How to create Ractive's subcomponents dynamically and change them programmatically

Question

I can instantiate (sub)components manually using tags, but I don\'t know how to do it dynamically, or, how to insert and remove different components in the same area using t

Answer 1

Here's a dynamic component:

Ractive.components.dynamic = Ractive.extend({
    template: '',
    components: {
        component: function() {
            return this.get('name');
        }
    },
    oninit: function(){
        this.observe('name', function(){
            this.reset();
        }, { init: false});
    }
});

Just pass in the name of the component it should implement:

See it in action below

Ractive.components.a = Ractive.extend({ template: 'I am A {{foo}}' });
Ractive.components.b = Ractive.extend({ template: 'I am B {{foo}}' });
Ractive.components.c = Ractive.extend({ template: 'I am C {{foo}}' });

Ractive.components.dynamic = Ractive.extend({
    template: '',
    components: {
        component: function() {
            return this.get('name');
        }
    },
    oninit: function(){
        this.observe('name', function(){
            this.reset();
        }, { init: false});
    }
});


var r = new Ractive({
    el: document.body,
    template: '#template',
    data: {
        foo: 'foo',
        list: ['a', 'b', 'c'],
        name: 'a'
    }
});
