froh.js v0.0.1
Froh is an easy to use, data oriented and component based javascript frontend framework.
Beginner tutorial
1) The key-value store
You can save Froh.set('key', obj) every kind of data. And you can fetch that data Froh.get('key') from anywhere in your whole project.
The main feature of this framework is that you can also listen on changes of that object, no matter how deep that change happens.
Example
Froh.set('serverlist', ['http://google.com', 'http://web.com', 'http://rothf.de']);
Froh.on('serverlist', function(){
console.log('Serverlist has been changed');
}
Froh.get('serverlist')[1] = 'http://facebook.com';
// console out: Serverlist has been changedNow every change on that object will be tracked and the cb function will be called.
2) Create a component
First of all you can write a Froh component that has to implement the function html().
This function will be called by a render() method automatically to redraw your defined component if you want so.
class WebsiteList extends FrohComponent {
html() {
return `<ul><li>${(Froh.get('websites') || []).join(`</li><li>`)}</li></ul>`;
}
}3) Froh.ready()
Wait for Froh to be ready, you know that from jQuery...
Froh.ready(function () {
...
}4) Go for it
Instantiate your component and attach your data to the Froh storage.
With Froh.on(...) you can add a listener function that will be called every time when the value of the key will be modified or overwritten.
Your FrohComponent also needs a place within the html document. If you pass a tag, or just the tagname of that html element Froh automatically shows the component within that html tag.
<!doctype html>
<html lang="en">
<head>
<title>Title</title>
<script type="application/javascript" src="Froh.js"></script>
<script type="application/javascript">
class WebsiteList extends FrohComponent {
html() {
return `<ul><li>${(Froh.get('websites') || []).join(`</li><li>`)}</li></ul>`;
}
}
Froh.ready(function () {
var websites = new WebsiteList('<websites>');
Froh.set('websites', ['http://google.de', 'http://amazon.de', 'http://myapp.js']);
Froh.on('websites', function(){
websites.render();
});
// Every modification on the stored object 'websites' will trigger the rerendering.
Froh.get('websites')[1] = 'http://web.de';
});
</script>
