ember-angle-bracket-invocation-polyfill

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 and `has-block` detection - **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.

ember-named-blocks-polyfill

A polyfill for the Yieldable Named Blocks feature in Ember.

ember-router-service-polyfill

This addon provides a best-effort polyfill for the `ember-routing-router-service` feature introduced in Ember.js 2.15. It allows developers to use the modern Router Service API in older Ember applications, facilitating smoother upgrades and consistent code patterns across different Ember versions. ## Key Features - **Router Service Injection** — Enables injection of the router service via `Ember.inject.service()` in components and other Ember objects. - **Transition Methods** — Provides `transitionTo` and `replaceWith` methods on the router service for programmatic navigation. - **Backwards Compatibility** — Designed to work with Ember versions as old as 2.4, bridging the gap until native support is available. - **Addon Support** — Allows addon authors to depend on the router service while maintaining compatibility with a wide range of Ember versions. ## Philosophy The project aims to provide a reliable, best-effort implementation of the Router Service API for older Ember versions, following the official RFC specification to ensure consistency with Ember's future direction.
