Over the previous few weeks, we noticed 55 weblog posts, GitHub Gists, and tweets that described how Ember can proceed to innovate in 2019. We thank everybody for taking part, by writing a submit, replying to 1, and discussing it on-line or on podcasts. Please be happy to proceed to jot down your #EmberJS2019 submit even after the deadline. 💖

As at all times, you’ll find all #EmberJS2019 posts at our neighborhood repo. (Thanks once more, @abhilashlr!)
@sarbbottam remembers how the new testing syntax had improved his productiveness remarkably. Sarbbottam, who has been making notes on testing since, graciously shared them with the entire neighborhood final week. 💯
Be taught extra in the present day about:
- Writing several types of assessments (unit, integration, and acceptance)
- Operating assessments
- Stubbing dependencies
We encourage you to try Sarbbottam’s information and share it with builders that ! 💛
As Ember aligns with native JavaScript extra every day, we get to reexamine the framework selections that we had made. For instance, how ought to we deal with occasions for enter components? @rwjblue and @stefanpenner met to talk about the historic context and options to utilizing the {{enter}} helper.
You possibly can be taught extra from their recorded interview and @balinterdi‘s notes and ideas.
@patocallaghan gave a lightning speak on “Visible Regression Testing Made Simple” on the April 2019 DublinJS Meetup. In his speak, Pat used Percy to scale visible regression testing from a handbook to an automatic workflow. You possibly can catch potential CSS bugs, take away sure varieties of assessments, and take care of giant refactors and migrations. “Types can generally make unhealthy issues occur.” Percy offers you confidence while you make massive modifications.
Take a look at the full lightning speak video simply revealed this week!
The current Request for Feedback (RFC), titled “Specific Service Injection,” proposes an replace to the way in which providers and different dependencies are registered, seemed up and injected in Ember apps. The proposal argues {that a} class-based syntax for dependency injection is extra specific than the present string-based API and subsequently preferable.
If you would like to be taught extra in regards to the new API design that’s proposed within the RFC, remember to learn the unique proposal and don’t forget to be part of the dialogue within the feedback!
Discovering parts that are not utilized in your utility anymore will be powerful. On account of alternative ways to invoke parts (with curly braces or angle brackets) and the syntactical ambiguity between invoking helpers and parts, it takes a while to prune your app from redundant parts manually.
However now you should utilize the brand-new addon Ember Unused Parts to clear up your codebase mechanically. Use the --stats flag to get helpful studies on the impression of your app optimization efforts as you go. Test it out in the present day!
This week we would prefer to thank @loganrosen, @bekzod, @sdebarros, @buschtoens, @rwjblue, @pzuraq, @efx, @runspired, @scalvert and @muziejus for his or her contributions to Ember and associated repositories! 💖
