🛤️ tracking: The Road to Polaris ✨

[runspired]

🌌 Universal

Note

Universal also presumes that we ship SchemaRecord (in the WarpDrive section)
for full utility, and that tasks in the Vite section are done.

• derisk decoupling EmberData from Ember's runloop

  • (upstream) Implement Render Aware Scheduler RFC

• EmberData without EmberSource

  • deprecate Store extending EmberObject
  • hook @ember-data/tracking for arbitrary signal implementations
    • and/or adopt StarbeamJS
    • and/or adopt Reactive Primitives proposal from TC39
  • replace @ember/debug (assert) usage with something not tied to ember-source
  • replace @ember/debug (warn, deprecate) usage with something not tied to ember-source
  • Configuration point for @ember/test-waiters for non-ember projects
  • replace @ember/string usage with something lighter of our own

⚡️ Vite

Tip

This section might be one of the easiest to complete for someone that understands
a bit of tooling without needing to dig into EmberData's library code.

• EmberData without EmberCLI
  • build config method
  • ship all packages in v2 format
  • stand-alone macros plugin for vite

💚 Typescript

Tip

This section might be one of the easiest to complete for someone that understands
typescript without needing to learn too much of EmberData's library code.

• rollup .d.ts files to reduce import surface area
• improve quality of types so we can mark them as stable

💡 API Documentation

• 🚧 FILL ME OUT 🚧

🔭 Guides

• Ember Guides rewritten to Polaris EmberData patterns
• SuperRentals tutorial rewritten to Polaris EmberData patterns
• Find somewhere to publish the in-repo guides we've written

🚢 Onboarding

• npx warp-drive|ember-data to run user through a flow that configures packages for them.

Really inspiring list!

@runspired is any CRDT support planned (https://blog.notmyidea.org/a-comparison-of-javascript-crdts.html)?
@Baltazore said it's could be implemented on top of custom handler

[runspired]

@lifeart built-in support for CRDT is not planned, and likely never will be due to how it overlaps with JSON:API operations, but yes, it could be implemented overtop of a handler

[sandstrom]

@lifeart If you have some free time, and would like to contribute to this roadmap, we'd be willing to sponsor your work on Ember Data.

Can discuss in more detail if you're interested (we're sponsoring runspired and rwjblue already).
