The Ember Times – Issue No. 112

3 min read

Come on Emberistas! 🐹

This week: announcing the official Ember Octane release plan 🏎🐹, watch talks from the first Chennai EmberJS Meetup 🇮🇳, read up on fun state management using Microstates 💡, get your tickets to EmberCamp Chicago 🍕, and last, but not least, help improve the EmberArray documentation 👩‍💻👨‍💻!

The time has come: Ember Octane is coming to your Ember application very soon! As recently announced in the official Ember Octane release plan, the very first edition of Ember is going to be released at the same time as the planned release date of Ember v3.14.

But what does it mean? By the time Ember 3.14 is published, the framework will include all Octane-related features and enable them by default. Additionally, the “Octane way” will be the primary and recommended way to build Ember apps. This will also be reflected in Ember’s official documentation (API Docs and Guides) and migration tools.

Wanna learn more about what is going to happen between now and the time Ember Octane lands? Looking for support for migrating and testing your apps with the Octane feature set? Be sure to give the official release plan a read, join the discussion on the # topic-octane-migration channel on the Ember Discord and get ready for Octane!!

On August 3, Chennai EmberJS featured 6 speakers at their inaugural Meetup: @gokatz, @ g13n, @kandhavivekraj, @astronomersiva, @ pranith024, and @rajasegar! They covered various topics, including Ember Octane, tuning web performance, accessibility, differential bundling, JAM stack, and how ASTs (abstract syntax trees) fuel codemods and help us auto-document Ember components. 💖

You can watch all six talks today on YouTube. To learn more about Chennai EmberJS, you can visit their website and follow them on TwitterMeetup, and the #as-india channel on Discord!

@brandynbennett details his experience using Microstates.js as an alternative to DDAU. He describes how him and his team created complex tables in their app’s UI that requires a lot of state to be passed around. The DDAU strategy, in this scenario, was unwieldy due to the number of arguments needed to set and difficult to keep in sync as they had to refetch the data for each event such as a sort happens.

Microstates.js provided immutability so that any change to the state will make all the didReceiveAttrs hooks and computed properties update while also guarding it from being changed by child components. It also provided helpers and macros that would automatically update the component properties when the state has changed, eliminating the need to pass an action for each piece of state.

Read the full blog post to see the tradeoffs and potential pitfalls when state management is done with Ember and Microstates.

EmberCamp Chicago is around the corner! Join the community on September 16th, 2019 for the second annual edition of the event, hosting 150+ of the world’s top Ember developers for a full day of Ember talks.

Learn all about modern Ember patterns, Embroider, insightful case studies from community leaders such as Edward Faulkner, Jen Weber, Dan Gebhardt, Marie Chatfield and many others!

Check out the full talk schedule and get your tickets today before they are sold out!

@locks asks for your help with improving the documentation for EmberArray. The goal is to review each method and property of EmberArray and see if we can provide a better explanation and code sample.
