The Big Dig

Migrating from 0.7.x

The 1.0 release should largely be a drop-in replacement coming from 0.7.x, but there are a few changes to be aware of:

• Referencing a local-class in a template that doesn't have a corresponding styles module is now a hard error (before it would silently fail and add no class to the target element).
• Using localClassNames or localClassNameBindings on a component with no template is no longer possible. You can either create an empty template for that component or import the styles module and set classNames or classNameBindings using the imported mapping, e.g. classNames: styles['my-local-class'].

Fixed

• The type declaration for localClassNames now uses the right identifier
• The error message when referencing a local-class in a template with no styles module is now more informative

If you're migrating from 0.7.x, see the release notes for the 1.0 betas for additional changes and fixes.

Decorations

Added

• The long awaited @localClassNames and @localClassName decorators, which work as parallels to ember-decorators' @classNames and @className, are now available. Thanks @buschtoens!

Fixed

• Turns out there was one breaking change from the 0.7 series: components must now have a template in order for their localClassNames and localClassNameBindings (as well as the decorator versions) to resolve. The error message for this scenario has been improved to provide more actionable details.

Ch-ch-changes

This release is the first beta for Ember CSS Modules 1.0. There are no known breaking changes since 0.7.10, but as described below, there were a few internal refactorings, so we'll run a beta series before christening the official 1.0 🎉

Added

• addPostcssPlugin now accepts multiple arguments (#103)

Fixed

• The template-only-glimmer-components feature should no longer conflict with ember-css-modules (#98)

Changed

• The majority of the runtime monkeypatching that was present in this addon has been removed in favor of build-time processing. The only remaining runtime code is the {{local-class}} helper and an extension to the Component class to support localClassNames and localClassNameBindings. (#99)

Super Scope

• Support importing styles via @value and composes: from addons with @scopeed names.

Party Like It's 1992

Fixed

• Ember 3.1 ships with a version of Glimmer that expects AST transforms to use a singular visitor key rather than plural visitors. So we do that. Big thanks to @luqman for tracking this down.
• The internal computed property we set up to support localClassNameBindings now uses Ember's defineProperty for compatibility with the ES5 getters overhaul.

Let's Pretend This Never Happened

This was a no-op republish of 0.7.7.

Prerelease Blues

Fixed

• Prerelease versions of Ember CLI are correctly detected now.

Lint Roller

Added

• The plugin system now supports a notion of lint plugins, which will activate for developing addons even when they're in devDependencies.

Everything is Awesome

Fixed

• The local-class template transform should now play nicely with ember-font-awesome's own transforms (thanks @buschtoens!)
• The plugin registry no longer explodes when addons with no package keywords are present (thanks @devotox!)

String Theory

Added

• The ability to use {{local-class}} to inject classes from other modules is now public and documented (thanks @kellyselden!)

Fixed

• localClassNameBindings now works with string values instead of just booleans (thanks @luxferresum!)
• headerFiles and footerFiles will now accept file paths with and without extensions
• Setup for localClassNames and localClassNameBindings now short circuits to avoid extra work for tagless components (thanks @garno!)
