CanJS’s StacheElement allows you to create Web Components with observable properties and live-bound templates.

``js
class Counter extends StacheElement {
static view =
Count: {{ this.count }}
+1
;

static props = {
count: 0
};

increment() {
this.count++;
}
}
customElements.define("my-counter", Counter);
`

Components shouldn’t be concerned with how data is fetched, updated, or cached.

CanJS provides the right abstractions for your model code to be cleanly separated from your UI code. Learn more…

CanJS’s stache templating language can directly read the state and values from Promises.

No need to write any extra code to determine whether a Promise is pending, resolved, or rejected. Learn more…

`handlebars
{{# if(this.promise.isPending) }}
Loading…
{{/ if }}
{{# if(this.promise.isRejected) }}
Error: {{ this.promise.reason }}
{{/ if }}
{{# if(this.promise.isResolved) }}
Result: {{ this.promise.value }}
{{/ if }}
``

After data is created, updated, or destroyed, CanJS automatically updates your lists for you.

Filtering and sorting are preserved, so you don’t have to manually update your lists or fetch the same data again. Learn more…
