 # ChangeLog
 This document contains an overview of all changes between Owl 1.x and
 Owl 2.x, with some pointers on how to update the code.
 Note that some of these changes can be magically implemented (for example, by
 patching the `setup` method of `Component` to auto register all the lifecycle
 methods as hooks). This will be done for the transition period, but will be
 removed after.

 ## Details/Rationale/Migration
 All changes are listed in no particular order.
 ### 1. component lifecycle methods are removed
 There was two ways to define hooks: the component methods (`willStart`, `mounted`, ...) and the hooks (`onWillStart`, `onMounted`, ...). In Owl 2, the component methods have been removed.
 Rationale: it makes the implementation simpler and slightly faster. Hooks are more composable
 than component methods. It enforces a single entry point to check all the useful lifecycle
 calls (instead of it being scattered in the component definition). It feels more "modern".
 Migration: lifecycle methods should be defined in the `setup`:
 ```js
 class MyComponent extends Component {
  mounted() {
    // do something
  }
 }
 ```
 should become:
 ```js
 class MyComponent extends Component {
  setup() {
    onMounted(() => {
      // do something
    });
  }
 }
 ```
 ### 2. components can no longer be mounted in a detached dom element
 Nor document fragment.
 Rationale: it is actually very difficult to do it: this implies that a component
 can be mounted more than once, that we need to check every time different status,
 that some elements is in the dom, and was a cause for bugs. Also, we don't use it
 in practice. Removing this means that we have a much simpler mental model of what
 happens.
 Migration: well, not really easy. The code needs to be refactored in a different way.
 ### 3. **`t-set` will no longer work to define a slot**
 The `t-set` directive cannot define a slot anymore. Only the `t-set-slot` directive
 can do it.
 Rationale: it was left for compatibility reason, but was deprecated anyway.
 Migration: `t-set` should be changed to `t-set-slot` (when defining a slot)
 Example:
 ```xml
 <SideBar><t t-set="content">content</t></SideBar>
 ```
 should become:
 ```xml
 <SideBar><t t-set-slot="content">content</t></SideBar>
 ```
 ### 4. `mount` method API is simpler
 Before, the `mount` method was used like this:
 ```js
 await mount(Root, { target: document.body });
 ```
 It is now simpler and takes the root component and a target argument:
 ```js
 await mount(Root, document.body);
 ```
 Rationale: the `mount` method is only useful anyway for small toy examples,
 because real applications will need to configure the templates, the translations,
 and other stuff. All complex usecases need to go through the new `App` class,
 that encapsulates the root of an owl application.
 ### 5. components can no longer be instantiated and mounted by hand
 In Owl 1, it was possible to instantiate a component by hand:
 ```js
 const root = new Root();
 await root.mount(document.body);
 ```
 Now, it is no longer possible. All component instantiations should be done by
 the owl framework itself.
 Rationale: the `mount` method does not make sense for all non root components.
 Also, the fact that it was possible for a component to be sometimes root,
 sometimes a child made for a weird constructor signature. This changes makes it
 simpler.
 Migration: all code doing that should use either the `mount` method (if the use
 case is simple enough, or the `App` class):
 ```js
 const app = new App(Root);
 app.configure({ templates: ..., ...});
 await app.mount(document.body);
 ```
 ### 6. components can no longer be unmounted/remounted
 Rationale: this is a very difficult feature to implement (it adds a lot of possible
 state transitions), compared to its benefit.
 Migration: all code using it should find a way to export and reimport the state
 ### 7. template name is no longer inferred from the class name
 Before, it was possible to define a component without specifying its template:
 ```js
 class Blabla extends Component {
    // no static template here!
 }
 ```
 with the `Blabla` template. It also worked with subclasses. But then, this means
 that the code had to look up all the super classes names to find the correct
 template.
 Rationale: in practice, it is not really useful, since all templates are usually
 namespaced: `web.SomeComponent` anyway. All the trouble to do that was just not
 worth it.
 Migration: simply explicitely defines the template key everytime:
 ```js
 class Blabla extends Component {}
 Blabla.template = "Blabla";
 ```
 ### 8. components no longer have a `shouldUpdate` method
 Rationale: `shouldUpdate` is a dangerous method to use, that may cause a lot of
 issues. Vue does not have such a mechanism (see https://github.com/vuejs/vue/issues/4255),
 because the reactivity system in Vue is smart enough to only rerender the minimal
 subset of components that is subscribed to a piece of state. Now, Owl 2 features
 a much more powerful reactivity system.
 Migration code: remove the `shouldUpdate` methods. Then, maybe the following
 ideas may help:
 - try to organize the state/architecture to minimize the number of state updates
 - take advantage of the finer reactivity system. For example, if we have a list
  of items, with a component for each item, we can write this:
  ```js
  class Item extends Component {
      setup() {
          this.item = useState(this.props.item); // and only use this, not props.item
      }
  }
  ```
  Doing so will make it that each `Item` component will register itself as an
  observer of its own item, and will be the only component being rerendered when
  its item object is updated.
 - use the `Memo` component to wrap some piece of template. `Memo` memoize its
  content, and only update itself if its props are different (shallow comparison):
  ```xml
    <Memo a="state.a" b="state.b"> 
        <t t-esc="state.a"/>
        <t t-esc="state.b"/>
        <t t-esc="state.c"/>
    </Memo>
  ```
 ### 9. component.el may be a text node, and is no longer `null`
 This comes from the fact that Owl 2 supports fragments (arbitrary content). When
 it is not defined, it was `null` in Owl 1 and is `undefined` in owl 2.
 ### 10. style/class on components are now regular props
 Before, it was possible to do this in a template:
 ```xml
 <Child style="..." class="..."/>
 ```
 (or with `t-att-style` and `t-att-class`). This does no longer work, as they are
 now considered normal props.
 Rationale: with the move to fragments, the semantics of where the style/class
 attribute should be set is unclear. Also, it is actually very hard to implement
 properly, in particular with higher order components. And another issue is that
 it (slightly) breaks the encapsulation of behaviour from the `Child` component
 perspective.
 Migration: each component that wishes to be customized should explicitely add
 the `class` and `style` attributes in its template. Also, the parent component
 should be aware that since we are talking about props, it should be a javascript expression:
 In parent:
 ```xml
 <Child class="'o_my_god'"/>
 ```
 and in child:
 ```xml
    <div t-att-class="props.class">
        ...
    </div>
 ```
 ### 11. components can no longer be mounted with position=self
 Rationale: this is due to the implementation of owl 2 virtual dom. The hack
 necessary to support position=self does not work. This position also is not
 compatible with the fact that a component can have a root `<div>` then later,
 change it to something else, or even a text node.
 Migration: no real way to do the same. Owl application needs to be appended or
 prepended in something, maybe a `div`.
 ### 12. `t-on` does not work on components any more
 In owl 1, it was possible to bind an event listener on a component tag in a
 template:
 ```xml
 <SomeComponent t-on-some-event="doSomething"/>
 ```
 This does not work any more.
 Rationale: with the support of fragments, there is no longer a canonical html
 element that we can refer. So, this makes it difficult to implement correctly
 and efficiently. Also, we noticed in practice that the event system was an issue
 in some cases, when components need to communicate before they are mounted. In
 those cases, the better solution is to directly use a callback.  Also, another
 conceptual issue with this is that it kind of breaks the component encapsulation.
 The child component kind of leak its own implementation to the outside world.
 Migration: a quick fix that may work in some cases is to simply bind the event
 handler on a parent htmlelement. A better way to do it, if possible, is to change
 the component API to accept explicitely a callback as props. 
 ```xml
 <SomeComponent onSomeEvent="doSomething"/>
 ```
 ### 13. Portal does no longer transfer DOM events
 In Owl 1, a Portal component would listen to events emitted on its portalled
 child, and redispatch them on itself. It no longer works.
 Rationale: Portal now supports an arbitrary content (so, more than one child,
 and potentially no html element), so it is already unclear what it should listen
 to. Also, redispatching events was an hack. And this changes allows the portal
 to render itself as a text node, which is nice. This is also in line with the
 fact that modern Owl moves toward using callback instead of `t-on` for communication.
 Migration: use callback if possible to communicate. Otherwise, use a sub env.
 ### 14. Portal does render as an empty text node instead of `<portal/>`
 That is pretty nice. No real migration needed.
 ### 15. Context is removed
 Context was an abstraction in Owl that was used to define some reactive state
 and to let some components subscribe to it, then only them would be rerendered
 if the context was updated. This has been removed.
 Rationale: first, the Context api and code was kind of awkward, which is a sign
 that the abstraction is not well thought. But the good news is that it is actually
 completely replaced by the new reactivity system, which is even more powerful,
 since it can tracks changes key by key.
 Migration: replace all uses of Context with the new reactivity system.
 ```js
 // somewhere, maybe in a service, or in the global env
 const context = observe({some: "state"})
 // in a component that would previously get a reference to the context:
 setup() {
    this.context = useState(context);
    // now the component is subscribed to the context and will react to any
    // change for any key read by the component, and only those changes
 }
 ```
 ### 16. `env` is now totally empty
 In Owl 1, the `env` object had to contain a QWeb instance. This was the way
 components would get a reference to their template function. It no longer works
 that way: the `env` object is now totally empty (from the perspective of Owl).
 It is now a user space concept, useful for the application.
 Rationale: first, there is no longer a QWeb class. Also, this changes simplifies
 the way components works internally.
 Migration: there is no proper way to get an equivalent. The closest is to get
 a reference to the root App using `this.__owl__.app`. If you need to do this,
 let us know. If this is a legitimate usecase, we may add a `useApp` hook.
 ### 17. `t-component` no longer accepts strings
 In owl 1, we could write this:
 ```xml
 <t t-component="Coucou"/>
 ```
 This meant that Owl would look for the component class like this: `components["Coucou"]`,
 so, essentially equivalent to `<Coucou/>`. In Owl 2, the `t-component` directive
 is assumed to be an expression evaluating to a component class:
 ```js
 class Parent extends Component {
  static template = xml`<t t-component="Child"/>`;
  Child = Child;
 }
 ```
 Rationale: it simply seems more consistent with the way directive works. Also,
 the implementation is slightly simpler.
 Migration: simply using `constructor.components.Coucou` instead of `Coucou` will
 do the trick.
 ### 18. most exports are exported at top level
 Most exports are flattened: for ex, `onMounted` is in owl, not in `owl.hooks`.
 Rationale: this makes it easier to work with, instead of importing stuff from 
 `owl`, then `owl.hooks` and `owl.tags` for example.
 Migration: all import code simply need to be slightly adapted.
 ### 19. Properties are no longer set as attributes
 Formerly, html properties `<input type="checkbox" t-att-checked="blah"/>` were
 set as property and as attribute, so, they would be visible in the DOM:
 `<input type="checkbox" checked="blah"/>`. Now, they are treated as property only:
 `<input type="checkbox"/>`.
 Rationale: this is actually simple to do, is faster, and makes more sense to me.
 ### 20. `t-foreach` should always have a corresponding `t-key`
 It was possible in Owl 1 to write a `t-foreach` without a `t-key`. In that case,
 the index was used as key.  Since it was clearly a possible bug, Owl 1 had a
 warning in some cases, when it could detect that there was definitely not a `t-key`.
 However, this was imperfect, and in some cases no warning was displayed. In Owl 2,
 the tag with a `t-foreach` has to have a corresponding `t-key`.
 Rationale: this makes it easier to avoid bugs.
 Migration: simply move the `t-key` to the tag with the `t-foreach`. If this is
 a situation where there is really not a need for a `t-key`, you can still add
 it with the `_index` suffix:
 ```xml
 <div t-foreach="items" t-as="item" t-key="item_index">
  ...
 </div>
 ```
 ### 21. `EventBus` api changed: it is now an `EventTarget`
 In Owl 1, the `EventBus` class was done manually, with a custom API. In Owl 2,
 it simply extends `EventTarget` (the native Dom class), so its implementation
 is basically only 5 lines long. This means that it has now the usual DOM interface:
 ```js
 bus.addEventListener('event-name', callback);
 ```
 Rationale: it makes it easier to have just one interface to remember, it makes
 the code simpler
 Migration: most bus methods need to be adapted. So, `bus.on("event-type", owner, (info) => {...})` has to be
 rewritten like this: `bus.addEventListener("event-type", (({detail: info}) => {...}).bind(owner))`.
 Do not forget to similarly replace `bus.off(...)` by `bus.removeEventListener(...)`
 ### 22. `Store` is removed
 The Store system had been abandoned in owl 2.
 Rationale: first, it was complicated to maintain. Second, it was not really
 used in Odoo. Finally, the new reactivity system seems to be a pretty good basis
 to write a store, and it should not take much work. Also, this can be done in
 user space (so, not necessarily at the framework level). Another point is that
 the store API was invented before the hooks, then was still a little awkward.
 Migration:
 - rewrite the code not to use a store
 - probably use the reactivity system instead and build a store class and a few
  hooks on top of it.
 ### 23. `Router` is removed
 Rationale: Router was not used that much, and it felt like it did not fit in Owl 2.
 Its API needs to be reworked, and we are not confident that it is a good
 experience to use it. Also, it can be done in userspace (it does not need specific
 integration at the framework level)
 Migration: reimport all missing piece from the code in Owl 1.
 ### 24. transition system is removed
 Rationale: this was a high ratio cost/value, with a lot of potential for bugs.
 We feel like there should be a way to reimplement in userspace the simple cases.
 Maybe something like: add a `t-ref` in the template, and define a hook `useFadeOut`
 that takes the ref, and add a fadeout class at initial render, then in mounted,
 wait for a micro tick and remove it.
 Migration: try to reimplement it manually. 
 ### 25. no more global components or templates
 It was possible in Owl 1 to register globally a component or a template. This is
 no longer the case in Owl 2.
 Rationale: first, this was a tradeoff: ease of use was gained, but at the cost
 of a higher complexity. Users had to know that there was a magic mechanism. Also,
 it was not used much in practice, and the cost of having to import manually components
 is low.  Finally, this can be mostly done in user space (for example, by subclassing
 `Component`).
 Migration: import manually all required global components, or find a way to organize
 the code to do it.
 ### 26. `AsyncRoot` utility component is removed
 Rationale: it was difficult to understand, never used, and not really useful.
 It seems better to control the asynchrony of an application by simply controlling
 how/when the state is updated, and how each component is loading/updating itself.
 Migration: remove the `AsyncRoot` component, then possibly, reorganize the code
 to fetch data in a higher order component, and using a `t-if/t-else` to display
 either a fallback when the data is not ready, or the actual component with data
 as props.  If there is no escape, and `AsyncRoot` is needed, please reach out to
 us so we can study this usecase.
 ### 27. `useSubEnv` only applies to child components
 In Owl 1, a call to `useSubEnv` would define a new environment for the children
 AND the component. It now only defines an environment for the children.
 Rationale: This was a subtle cause for bugs: some code had to be rrun
 before the call to `useSubEnv`, otherwise it could interfere with the sub environment.
 ### 28. `env` is now frozen
 In Owl 2, the `env` object is frozen. It can no longer be modified (structurally)
 arbitrarily. 
 Rationale: it seems like the `env` object purpose is to have a global channel of
 communication between components. It is however scary if anyone can add something
 to it.  The usual use case is to add something to the environment for some child
 components. This use case still works with `useSubEnv`.
 Migration: use `useSubEnv` instead of writing directly to the env.  Also, note
 that the environment given to the App can initially contain anything.
 ### 29. `t-ref` does not work on component
 Before, `t-ref` could be used to get a reference to a child component. It no
 longer works.
 Rationale: the possibility of having a ref to a child component breaks the
 encapsulation provided by Owl components: a child component now has a private
 and a public interface.  Another issue is that it may be unclear when the ref
 should be set: is the component active on setup, or on mounted? Also, it is
 kind of awkward to implement.
 Migration: the `env` and `props` should provide a communication channel wide enough:
 the sub component can expose its public API by calling a callback at the proper
 timing, or by triggering an event.
 ### 30. `t-on` does not accept expressions, only functions
 In Owl 1, it was possible to define simple expressions inline, in a template:
 ```xml
 <button t-on-click="state.value = state.value + 1">blabla</button>
 <button t-on-click="someFunction(someVar)">blabla</button>
 ```
 This does not work anymore. Now, the `t-on` directive assumes that what it get is
 a function.
 Rationale: the fact that owl 1 had to support expressions meant that it was not
 possible to properly inject the event in general. With this restriction, Owl 2
 can support more general use cases. Also, the examples above can simply be
 wrapped in a lambda function. 
 Migration: use lambda functions. For example, the two examples above can be
 adapted like this:
 ```xml
 <button t-on-click="() => state.value = state.value + 1">blabla</button>
 <button t-on-click="() => this.someFunction(someVar)">blabla</button>
 ```
 ### 31. components can now have arbitrary content
 Before Owl 2, components had to limit themselves to one single htmlelement as
 root. Now, the content is arbitrary: it can be empty, or multiple html elements.
 So, the following template works for components:
 ```xml
  <div>1</div>
  <div>2</div>
  hello

 # 🦉 How to debug Owl applications 🦉
 Non trivial applications become quickly more difficult to understand. It is then
 useful to have a solid understanding of what is going on. To help with that,
 logging useful information is extremely valuable. There is a [javascript file](../../tools/debug.js) which can be evaluated in an application.
 Once it is executed, it will log a lot of information on each component main hooks. The following code is a minified version to make it easier to copy/paste:
 ```
 function debugOwl(t,e){let n,o="[OWL_DEBUG]";function r(t){let e;try{e=JSON.stringify(t||{})}catch(t){e="<JSON error>"}return e.length>200&&(e=e.slice(0,200)+"..."),e}if(Object.defineProperty(t.Component,"current",{get:()=>n,set(s){n=s;const i=s.constructor.name;if(e.componentBlackList&&e.componentBlackList.test(i))return;if(e.componentWhiteList&&!e.componentWhiteList.test(i))return;let l;Object.defineProperty(n,"__owl__",{get:()=>l,set(n){!function(n,s,i){let l=`${s}<id=${i}>`,c=t=>console.log(`${o} ${l} ${t}`),u=t=>(!e.methodBlackList||!e.methodBlackList.includes(t))&&!(e.methodWhiteList&&!e.methodWhiteList.includes(t));u("constructor")&&c(`constructor, props=${r(n.props)}`);u("willStart")&&t.hooks.onWillStart(()=>{c("willStart")});u("mounted")&&t.hooks.onMounted(()=>{c("mounted")});u("willUpdateProps")&&t.hooks.onWillUpdateProps(t=>{c(`willUpdateProps, nextprops=${r(t)}`)});u("willPatch")&&t.hooks.onWillPatch(()=>{c("willPatch")});u("patched")&&t.hooks.onPatched(()=>{c("patched")});u("willUnmount")&&t.hooks.onWillUnmount(()=>{c("willUnmount")});const d=n.__render.bind(n);n.__render=function(...t){c("rendering template"),d(...t)};const h=n.render.bind(n);n.render=function(...t){const e=n.__owl__;let o="render";return e.isMounted||e.currentFiber||(o+=" (warning: component is not mounted, this render has no effect)"),c(o),h(...t)};const p=n.mount.bind(n);n.mount=function(...t){return c("mount"),p(...t)}}(s,i,(l=n).id)}})}}),e.logScheduler){let e=t.Component.scheduler.start,n=t.Component.scheduler.stop;t.Component.scheduler.start=function(){this.isRunning||console.log(`${o} scheduler: start running tasks queue`),e.call(this)},t.Component.scheduler.stop=function(){this.isRunning&&console.log(`${o} scheduler: stop running tasks queue`),n.call(this)}}if(e.logStore){let e=t.Store.prototype.dispatch;t.Store.prototype.dispatch=function(t,...n){return console.log(`${o} store: action '${t}' dispatched.

 Adding new keys is supported. Once any part of the state has been changed, a
 rendering is scheduled in the next microtask tick (promise queue).
 ## State Management
 Managing the state of an application is a tricky issue. Many solutions have
 been proposed these last few years. It also depends on the kind of application we
 are talking about. A small application may not need much more than a simple
 object to contain its state.
 However, there are some common solutions for React and Vue: redux and vuex.
 Both of them are a centralized store that own the state, and they dictate how
 the state can be mutated.
 **Redux**
 In Redux, the state is mutated by reducers. Reducers are functions
 that modify the state by returning a different object:
 ```javascript
  ...
  switch (action.type) {
    case ADD_TODO: {
      const { id, content } = action.payload;
      return {
        ...state,
        allIds: [...state.allIds, id],
        byIds: {
          ...state.byIds,
          [id]: {
            content,
            completed: false
          }
        }
      };
    }
 ```
 This is a little bit awkward to write, but this allows the component system to
 check if a part of the state was changed. This is exactly what is done by the
 `connect` function: it create a _connected_ component, which is subscribed to
 the state and triggers a rerender if some part of the state was modified.
 **VueX**
 VueX is based on a different principle: the state is mutated through
 some special functions (the mutations), which modify the state in place:
 ```javascript
    function ({state}, payload) {
        const { id, content } = payload;
        const message = {id, content, completed: false};
        state.messages.push(message)
    }
 ```
 This is simpler, but there is a little bit more happening behind the scene:
 each key from the state is silently replaced by getters and setters, and VueX
 keeps track of who get data, and retrigger a render when it was changed.
 **Owl**
 Owl store is a little bit like a mix of redux and vuex: it has actions (but not
 mutations), and like VueX, it keeps track of the state changes. However, it does
 not notify a component when the state changes. Instead, components need to connect
 to the store like in redux, with the `useStore` hook (see the [store documentation](../reference/store.md#connecting-a-component)).
 ```javascript
 const actions = {
  increment({ state }, val) {
    state.counter.value += val;
  },
 };
 const state = {
  counter: { value: 0 },
 };
 const store = new owl.Store({ state, actions });
 class Counter extends Component {
  static template = xml`
      <button t-name="Counter" t-on-click="dispatch('increment')">
        Click Me! [<t t-esc="counter.value"/>]

 # 🦉 Mounting an application 🦉
 ## Content

 ## Overview
 Mounting an Owl application is done by using the `mount` method (available in
 `owl.mount` if you are using the iife build, or it can be directly imported
 from `owl` if you are using a module system):
 ```js
 const mount = { owl }; // if owl is available as an object
 const env = { ... };
 const app = await mount(MyComponent, { target: document.body, env });
 ```
 Another example:
 ```js
 const config = {
  env: ...,
  props: ...,
  target: document.body,
  position: "self",
 };
 const app = await mount(App, config);
 ```
 A common way to initialize an application is to first setup an environment,
 then to call the `mount` method.
 ## API
 Mount takes two parameters:
 - `C`, which should be a component class (NOT instance),
 - `params`, which is an object with the following keys:
  - `target (HTMLElement | DocumentFragment)`: the target of the mount operation
  - `env (optional, Env)` an environment
  - `position (optional, "first-child" | "last-child" | "self")` the position
    where it should be mounted (see below for more informations)
  - `props (optional, any)`: some initial values that are given as props. Useful
    when the root component is configurable, or when testing sub components
 Here are the various positions supported by Owl:
 - `first-child`: with this option, the component will be prepended inside the target,
 - `last-child` (default value): with this option, the component will be
  appended in the target element,
 - `self`: the target will be used as the root element for the component. This
  means that the target has to be an HTMLElement (and not a document fragment).
  In this situation, it is possible that the component cannot be unmounted. For
  example, if its target is `document.body`.
 The `mount` method returns a promise that resolves to the instance of the created
 component.

 ## Overview
 It is often useful to organize an application around urls. If the application is
 a single page application, then we need a way to manage those urls in the browser.
 This is why there are many different routers for different frameworks. A generic
 router can do the job just fine, but a specialized router for Owl can give a
 better developer experience.
 The Owl router support the following features:
 - `history` or `hash` mode
 - declarative routes
 - route redirection
 - navigation guards
 - parameterized routes
 - a `<Link/>` component
 - a `<RouteComponent/>` component
 Note that it is still in early stage of developments, and there are probably
 still some issues.
 ## Example
 To use the Owl router, there are some steps that needs to be done:
 - declare some routes
 - create a router
 - add it to the environment
 ```js
 async function protectRoute({ env, to }) {
  if (!env.session.authUser) {
    env.session.setNextRoute(to.name);
    return { to: "SIGN_IN" };
  }
  return true;
 }
 export const ROUTES = [
  { name: "LANDING", path: "/", component: Landing },
  { name: "TASK", path: "/tasks/{{id}}", component: Task },
  { name: "SIGN_UP", path: "/signup", component: SignUp },
  { name: "SIGN_IN", path: "/signin", component: SignIn },
  { name: "ADMIN", path: "/admin", component: Admin, beforeRouteEnter: protectRoute },
  { name: "ACCOUNT", path: "/account", component: Account, beforeRouteEnter: protectRoute },
  { name: "UNKNOWN", path: "*", redirect: { to: "LANDING" } }
 ];
 function makeEnvironment() {
    ...
    const env = { qweb };
    env.session = new Session(env);
    env.router = new owl.router.Router(env, ROUTES);
    await env.router.start();
    return env;
 }
 App.env = makeEnvironment();
 // create root component here
 ```
 Notice that the router needs to be started. This is an asynchronous operation
 because it needs to apply the potential navigation guards on the current route
 (which may or may not mean that the application is redirected to another route).
 ## Reference
 ### Route definition
 A route need to be defined as an object with the following keys:
 - `name` (optional): a (unique) string useful to identify the current route. If not
  given, it will be assigned an automatic name,
 - `path`: a string describing the url. It can be static: `/admin` or dynamic: `/users/{{id}}`.
  It also can be `*`, to catch all remaining routes.
 - `component` (optional): an Owl component that will be used by the `t-routecomponent`
  directive if the route is active
 - `redirect` (optional): should be destination object (with optional keys `path`, `to` and `params`) if given, the application will be redirected to the destination whenever we match this route
 - `beforeRouteEnter`: defines a [navigation guard](#navigation-guards).
 ### `Router`
 The `Router` constructor takes three arguments:
 - `env`: a valid environment,
 - a list of routes,
 - an optional object (with the only key `mode` which can be `history` (default
  value) or `hash`).
 `history` will use the browser [History API](https://developer.mozilla.org/en-US/docs/Web/API/History_API) as the mechanism to manage URL.\
 Example: `https://yourdomain.tld/my_custom_route`.\
 For this mechanism to work, you need a way to configure your web server accordingly.
 `hash` will manipulate the hash of the URL.\
 Example: `https://yourdomain.tld/index.html#/my_custom_route`.
 ```js
 const ROUTES = [...];
 const router = new owl.router.Router(env, ROUTES, {mode: 'history'});
 ```
 Note that the route are defined in a list, and the order matters: the router
 tries to find a match by going down the list.
 The router needs to be added to the environment in the `router` sub key.
 Once a router is created, it needs to be started. This is necessary to initialize
 its current state to the current URL (and also, to potentially apply any
 navigation guards and/or redirecting).
 ```js
 await router.start();
 ```
 Once started, the router will keep track of the current url and reflect its
 value in two keys:
 - `router.currentRoute`
 - `router.currentParams`
 The router also has a `navigate` method, useful to programmatically change the
 application to another state (and the url):
 ```js
 router.navigate({ to: "USER", params: { id: 51 } });
 ```
 ### Navigation Guards
 Navigation guards are very useful to be able to execute some business logic/
 perform some actions or redirect to other routes whenever the application is
 entering a new route. For example, the following guard checks if there is an
 authenticated user, and if it is not the case, redirect to the sign in route.
 ```js
 async function protectRoute({ env, to }) {
  if (!env.session.authUser) {
    env.session.setNextRoute(to.name);
    return { to: "SIGN_IN" };
  }
  return true;
 }
 ```
 A navigation guard is a function that returns a promise, which either resolves
 to `true` (the navigation is accepted), or to another destination object.
 ### `RouteComponent`
 The `RouteComponent` component directs Owl to render the component associated
 to the currently active route (if any):
 ```xml
 <div t-name="App">
    <NavBar />
    <RouteComponent />
 </div>
 ```
 ### `Link`
 The `Link` component is a Owl component which render as a `<a>` tag with any
 content. It will compute the proper href from its props, and allow Owl to
 properly navigate to a given url if clicked on it.
 ```xml
 <Link to="'HOME'">Home</Link>

 ## Overview
 Managing the state in an application is not an easy task. In some cases, the
 state of an application can be part of the component tree, in a natural way.
 However, there are situations where some parts of the state need to be displayed
 in various parts of the user interface, and then, it is not obvious which
 component should own which part of the state.
 Owl's solution to this issue is a centralized store. It is a class that owns
 some (or all) state, and lets the developer update it in a structured way, with
 `actions`. Owl components can then connect to the store to read their relevant
 state, and they will be rerendered if the state is updated.
 Note: Owl store is inspired by React Redux and VueX.
 ## Example
 Here is what a simple store looks like:
 ```js
 const actions = {
  addTodo({ state }, message) {
    state.todos.push({
      id: state.nextId++,
      message,
      isCompleted: false,
    });
  },
 };
 const state = {
  todos: [],
  nextId: 1,
 };
 const store = new owl.Store({ state, actions });
 store.on("update", null, () => console.log(store.state));
 // updating the state
 store.dispatch("addTodo", "fix all bugs");
 ```
 This example shows how a store can be defined and used. Note that in most cases,
 actions will be dispatched by connected components.
 ## Reference
 ### `Store`
 The store is a simple [`owl.EventBus`](event_bus.md) that triggers `update` events
 whenever its state is changed. Note that these events are triggered only after a
 microtask tick, so only one event will be triggered for any number of state changes in a
 call stack.
 Also, it is important to mention that the state is observed (with an `owl.Observer`),
 which is the reason why it is able to know if it was changed. See the
 [Observer](observer.md)'s documentation for more details.
 The `Store` class is quite small. It has two public methods:
 - its constructor
 - `dispatch`
 The constructor takes a configuration object with four (optional) keys:
 - the initial state
 - the actions
 - the getters
 - the environment
 ```javascript
 const config = {
  state,
  actions,
  getters,
  env,
 };
 const store = new Store(config);
 ```
 ### Actions
 Actions are used to coordinate state changes. It can be used for both synchronous
 and asynchronous logic.
 ```js
 const actions = {
  async login({ state }, info) {
    state.loginState = "pending";
    try {
      const loginInfo = await doSomeRPC("/login/", info);
      state.loginState = loginInfo;
    } catch (e) {
      state.loginState = "error";
    }
  },
 };
 ```
 The first argument to an action method is an object with four keys:
 - `state`: the current state of the store content,
 - `dispatch`: a function that can be used to dispatch other actions,
 - `getters`: an object containing all getters defined in the store,
 - `env`: the current environment. This is useful sometimes, in particular if
  an action needs to apply some side effects (such as performing an rpc), and
  the `rpc` method is located in the environment.
 Actions are called with the `dispatch` method on the store, and can receive an
 arbitrary number of arguments.
 ```js
 store.dispatch("login", someInfo);
 ```
 Note that anything returned by an action will also be returned by the `dispatch`
 call.
 Also, it is important to be aware that we need to be careful with asynchronous
 logic. Each state change will potentially trigger a rerendering, so we need to
 make sure that we do not have a partially corrupted state. Here is an example that
 is likely not a good idea:
 ```javascript
 const actions = {
  async fetchSomeData({ state }, recordId) {
    state.recordId = recordId;
    const data = await doSomeRPC("/read/", recordId);
    state.recordData = data;
  },
 };
 ```
 In the previous example, there is a period of time in which the state has a
 `recordId` which does not correspond to the `recordData`. It is more likely that
 we want an atomic update: updating the `recordId` at the same time as the `recordData`
 values:
 ```javascript
 const actions = {
  async fetchSomeData({ state }, recordId) {
    const data = await doSomeRPC("/read/", recordId);
    state.recordId = recordId;
    state.recordData = data;
  },
 };
 ```
 ### Getters
 Usually, data contained in the store will be stored in a normalized way. For
 example,
 ```js
 {
    posts: [{id: 11, authorId: 4, content: 'Greetings'}],
    authors: [{id: 4, name: 'John'}]
 }
 ```
 However, the user interface will probably need some denormalized data like
 ```js
 {id: 11, author: {id: 4, name: 'John'}, content: 'Greetings'}
 ```
 This is what `getters` are for: they give a centralized way to process and
 transform the data contained in the store.
 ```js
 const getters = {
  getPost({ state }, id) {
    const post = state.posts.find((p) => p.id === id);
    const author = state.authors.find((a) => a.id === post.id);
    return {
      id,
      author,
      content: post.content,
    };
  },
 };
 // somewhere else
 const post = store.getters.getPost(id);
 ```
 Getters take _at most_ one argument.
 Note that getters are not cached.
 ### Connecting a Component
 At some point, we need a way to interact with the store from a component. This
 means that the component needs a reference to the store. By default, it looks
 for it in the `env.store` key. However, this can be configured with the `useStore`
 hook.
 Every component-store interactions are done with the help of the three store hooks:
 - [`useStore`](#usestore) to subscribe a component to some part of the store state,
 - [`useDispatch`](#usedispatch) to get a reference to a dispatch function,
 - [`useGetters`](#usegetters) to get a reference to the getters defined in the store.
 Assume we have this store:
 ```javascript
 const actions = {
  increment({ state }, val) {
    state.counter.value += val;
  },
 };
 const state = {
  counter: { value: 0 },
 };
 const store = new owl.Store({ state, actions });
 ```
 To make it accessible to the complete application, we will put it in the
 environment:
 ```js
 // in this example, the root component is App
 App.env.store = store;
 ```
 A counter component can then select this value and dispatch an action like this:
 ```js
 class Counter extends Component {
  counter = useStore((state) => state.counter);
  dispatch = useDispatch();
 }
 const counter = new Counter({ store, qweb });
 ```
 ```xml
 <button t-name="Counter" t-on-click="dispatch('increment')">
  Click Me! [<t t-esc="counter.value"/>]
 </button>
 ```
 ### `useStore`
 The `useStore` hook is used to select some part of the store state. It accepts
 two arguments:
 - a selector function, which takes the store state as first argument (and the
  component props as second argument) and which must return the part of the
  store state that will be made available and observed for changes,
 - optionally, an object which can have the following optional keys:
  - a `store` key containing a store object if we want to use another store than
    the default store,
  - an `isEqual` key containing an equality function if we want to specialize
    the comparison (the function must accept two arguments: the previous result
    and the new result, and must return whether they are equal),
  - and an `onUpdate` key containing an update function if we want to execute an
    arbitrary code every time the selected state changes (the function will
    receive one argument, the new result, and can execute arbitrary code).
 If the `useStore` selector returns a sub part of the store state, the component
 will only be rerendered whenever this part of the state changes. Otherwise, it
 will perform a strict equality check (unless the `isEqual` option is defined,
 then it will call it) and will update the component every time this check fails.
 Note that if the selector function returns a primitive type, the result of
 `useStore` will be immutable and it will not react to changes. In this case, it
 is important to define the `onUpdate` option to properly update the value
 manually when it changes.
 Also, the return value from `useStore` is not supposed to be modified. The store
 state should only be updated with actions.
 ### `useDispatch`
 The `useDispatch` hook is useful when a component needs to be able to dispatch
 actions. It takes an optional argument, which is a store. If not given, it will
 use the store in the environment.
 Note that a component does not need to be connected in any other way to the store.
 For example:
 ```js
 class DoSomethingButton extends Component {
  static template = xml`<button t-on-click="dispatch('something')">Click</button>`;
  dispatch = useDispatch();
 }
 ```
 ### `useGetters`
 The `useGetters` hook is useful when a component needs to be able to use the
 getters defined in a store. It takes an optional argument, which is a store. If
 not given, it will use the store in the environment.
 Note that a component does not need to be connected in any other way to the store.
 For example:
 ```js
 class InfoButton extends Component {
  static template = xml`<span><t t-esc="getters.somevalue()"></span>`;
  getters = useGetters();
 }
 ```
 ### Semantics
 The `Store` class and the `useStore` hook try to be smart and to optimize as much
 as possible the rendering and update process. What is important to know is:
 - components are always updated in the order of their creation (so, parent
  before children),
 - they are updated only if they are in the DOM,
 - if a parent is asynchronous, the system will wait for it to complete its
  update before updating other components,
 - in general, updates are not coordinated. This is not a problem for synchronous
  components, but if there are many asynchronous components, this could lead to
  a situation where some part of the UI is updated and some other part of the UI is
  not updated.
 ### Good Practices
 - avoid asynchronous components as much as possible. Asynchronous components
  lead to situations where parts of the UI is not updated immediately,
 - do not be afraid to connect many components, parent or children if needed. For
  example, a `MessageList` component could get a list of ids in its `useStore`
  call and a `Message` component could get the data of its own
  message,
 - since the `useStore` function is called for each connected component,
  for each state update, it is important to make sure that these functions are
  as fast as possible.
