Simple JS dependency injection container
#### Defining services
```js
container.set('storage', function(container) {
return new Storage;
});
container.set('cache', function(container) {
return new Cache(container.get('storage'));
});
```
#### Defining factory services
```js
container.set('cache', container.factory(function(container) {
return new Cache(container.get('storage'));
}));
```
#### Modifying services after definition
```js
container.extend('cache', function(cache, container) {
cache.setTtl(100);
return cache;
});
```
#### Defining you factory*
```js
container.protect('cache', function(container) {
return new Cache(container.get('storage'));
});
```
#### Sample application
```js
var app = new Container;
app.set('app', function(container) {
return {
run: function() {
console.log('App start');
container.get('table').render();
container.get('newInstance').render();
container.get('newInstance').render();
container.get('newInstance').render();
container.get('myFactory').render();
container.get('myFactory').render();
container.get('myFactory').render();
console.log('App end');
}
};
});
app.set('table', function(container) {
var row = container.get('row');
return {
render: function () {
row.render(1);
row.render(2);
row.render(3);
},
setRow: function(value) {
row = value;
}
};
});
app.extend('table', function(table, container) {
var row2 = container.get('row2');
table.setRow(row2);
return table;
});
app.set('newInstance', app.factory(function(container) {
var random = Math.random();
return {
render: function () {
console.log('newInstance -> ' + random);
}
};
}));
app.protect('myFactory', function (container) {
var random = Math.random();
return {
render: function () {
console.log('instance from my myFactory -> ' + random);
}
};
});
app.set('row', function(container) {
var random = Math.random();
return {
render: function (value) {
console.log('render row: ' + value + ' -> ' + random);
}
};
});
app.set('row2', function(container) {
var random = Math.random();
return {
render: function (value) {
console.log('render row2: ' + value + ' -> ' + random);
}
};
});
app.get('app').run();
```
