Read the newly published Ember 2019-2020 Roadmap RFC 🐹, tune in to learn about GraphQL and Ember 👨💻, join EmberCamp Chicago (Sept 16th) 🍕, learn why you shouldn't use observers ✋, small things matter ✏️, and Super Rentals tutorial in Octane 🚀!
Reducing the size and conceptual complexity of Ember.
Improving ease of adoption.
This will be done by continuing to simplify Ember, modernizing our build system, enabling better accessibility (a11y) by default, and optimizing for growth by sharing how Ember Octane is modern, productive, and fun.
As your application grows, a change to data can trigger your observers in unexpected ways. The chain of dependencies grows and can form a cycle — a circular dependency — without your knowing. Observer A calls observer B, which calls A again, which then... 😨
What we need is a rule that we can enforce locally to prevent cycles from forming at the global level. You've likely heard of this rule already: Data Down, Action Up (DDAU). 💡
We often feature awesome blogposts, intricate RFCs and helpful addons in the Times. But in such a large ecosystem and community, the small things also matter. @backspace and @Imon-Haque both contributed by just changing one file on the Ember website. Fixing a typo or a broken link that you stumble upon might seem really small, but it is valuable because it makes everyone's Ember experience better. So if you find something small, feel free to fix it by clicking the ✏️ on GitHub and creating a PR.
If you've been looking for an example of what an app written in Ember Octane looks like, look no further than the rewrite of the Super Rentals Tutorial that's been a part of the Ember.js guides for quite a while now.
