Ember 4.10 released 🐹

Ember 4.10 was recently released!

This release included several new features for Ember.js including the introduction of the @ember/owner package as specified in the API for Type-Only Imports RFC, 2 bug fixes for Ember.js and several deprecations. The release also includes 5 new features for Ember CLI.

Head on over to the 4.10 release blog post and give it a read today!

ember-template-lint 5.0.0 released 🧹

Version 5.0 has been released for ember-template-lint, the linter for best practices with Ember handlebars templates.

The key changes include:

  • Linting embedded templates by default
  • Adding nearly a dozen rules to the recommended config
  • Changing a few rule names and option defaults
  • Dropping support for old versions of Node

🎤 EmberConf News

We know folks are getting excited about EmberConf and might be wondering when it's happening. Currently, we're still getting our ducks in a row. After three years of virtual EmberConf, we're working out a way to match everybody's expectations around a possible hybrid conference. In the meantime, you can definitely keep working on those proposals and we’ll release more details as soon as we can. Historically, EmberConf has happened in March, but this time it will be later in the year. Hope to see you there!

✨ The new addons on the block

  • ember-blur - Geordan Neukum (@geneukum) provides us an Ember modifier that allows you to blur an element dynamically.
  • ember-tsparticles - Ignace Maes (@IgnaceMaes) made this addon that creates an Ember.js component for using tsParticles. This allows you to create highly customizable JavaScript particles effects, confetti explosions and fireworks animations and use them as animated backgrounds for your website.

🚀 Accelerating Code Delivery By 97% With Yarn Workspaces

Jordan Hawker (@elwayman02) details in this blogpost how they moved to Yarn Workspaces and how it improved the lead time for delivering commits to their deployment pipeline, from 39 hours to 125 mins. Yarn workspaces enabled the evolution of the application architecture without sacrificing the benefits of their previous multi-repo strategy. This post will give you the insight to see if this solution might benefit you.

"While one approach may serve well at a given point in time, there is no one-size-fits-all solution."

▶️ Wacky Tricks We Use in Publishing TypeScript Types

In this YouTube video, Chris Krycho (@chriskrycho) and Asa Kusuma (@asakusuma) discussed how we are publishing TypeScript types for Ember. Chris discusses how it is difficult for TypeScript to resolve types for ember-source given the public API for Ember is usually not imported directly from ember-source but from packages such as @ember/utils or @ember/object. Learn more by watching the full video on YouTube where “despite all the shenanigans” we are able to get Ember’s type to be “stable” and publish from Ember’s own TS source code.

📣 A new codemod to migrate addons to v2 format

With one command, you can get started with migrating Ember addons to v2 format:

npx ember-codemod-v1-to-v2

ember-codemod-v1-to-v2 helps you meet the latest standards set by @embroider/addon-blueprint. The codemod takes care of moving files and updating references to the moved files, while you remain in charge of re-configuring the packages.

Isaac Lee (@ijlee2) hopes that ember-codemod-v1-to-v2, along with ember-addon-migrator, can help you push Embroider forward. Check out ember-container-query for a real-life example.
