This project features three example to illustrate how to work with the web-core framework:
- _benchmarks_ is a small application to test large number of widgets,
- _todoapp_ is the classical todo application (from the todomvc project),
## Benchmarks

Note that each message is itself a widget, with a sub widget. This
example could be made faster (by not using subwidgets), but the point is to observe/measure the overhead of the Component class.
## Todo App
The Todo App is the classical todo application from _http://todomvc.com/_. It is a good mini application with non trivial data structures and interface updates.
```
npm run example:todoapp:build # make a build in dist/examples/
npm run example:todoapp:dev # make a build in dist/examples/, and make a live server to access it
```
It is implemented with the Store class (as in redux/vuex).
