ember-angle-bracket-invocation-polyfill
Polyfill for Ember.js angle bracket component invocation syntax, enabling modern component usage in older Ember versions.
Overview
This Ember addon provides a polyfill for the angle bracket invocation syntax introduced in Ember RFCs 311 and 457. It allows developers to use the modern component invocation style with @ prefixed arguments and cleaner template syntax in Ember applications running versions 2.12 through 3.9.
Key Features
- Angle Bracket Syntax — Enables invoking components using
<ComponentName />instead of curly braces - Argument Passing — Supports passing arguments with
@prefix like@title={{value}} - Attribute Support — Allows passing HTML attributes without
@prefix for component root elements - Block Support — Supports block components with
as |params|syntax andhas-blockdetection - Path Invocation — Enables invoking components using nested paths like
<some.thing>or<Foo::Bar /> - Backward Compatibility — Completely inert when running Ember 3.10 or higher, only activates for older versions
- Comprehensive Coverage — Polyfills all features described in the relevant RFCs with no known limitations
Philosophy
The addon follows Ember's philosophy of progressive enhancement, allowing teams to adopt modern component syntax incrementally while maintaining compatibility with existing codebases running older Ember versions.
