Intent to implement: Bind

[dreamofabear]

Summary

Bind is a new AMP extension that allows elements to mutate in response to user actions or data changes via data binding and simple JS-like expressions.

This will allow publishers to build responsive UIs for use cases not covered by existing AMP extended components. See #5059 for possible use cases.

Usage

In this example, the <p> element will have its textContent changed from "" to "Hello World".

<amp-dataset id=”foo”>{ bar: “Hello World” }</amp-dataset>
<p [text]=”foo.bar”></p>

Syntax is subject to change.

Details

Syntax discussion: #5760

@choumx — does this make sense to put in the sprint kicking off today, since Bind is in progress?

[dreamofabear]

@ericlindley-g Moving back to prioritized FRs since this is a top-level tracking issue.

[ericlindley-g]

Makes sense — thanks!

[adelinamart]

@choumx any updates here? Thanks.

[dreamofabear]

Yes! Closing since this is launching in next release.
