Planning Meeting Notes

Motivations

• Bug backlog

• Goals and current 6-month roadmap

• GitHub user feedback (👍s)

• Feedback from customer interviews, social media, past iteration plans

• Visual Studio and Visual Studio Code feedback, as well as new functionality demands

• Actionable PRs (need to make a call)

• Language

  • Type System Innovation
    • Assertion Signatures
    • Recursive Type References
  • Standards Conformance
    • ECMAScript Private Fields
    • Nullish Coalescing
    • Optional Chaining
    • Top level await
    • Transition plan for class fields

• Compiler

  • --declaration and --allowJs
  • --declaration and --isolatedModules
  • Investigate compiler plugin API

• Infrastructure

  • Migrate repo to ESLint
  • Investigate smaller package publish
    • Might have ideas for removing unnecessary files.
  • Dual-publishing @types on GitHub package registry
    • Today, types packages are automatically fetched to power IntelliSense in VS and VS Code.
    • GitHub now provides its own registry.
    • We want to ensure that there is some level of redundancy.

• Editor Productivity

  • Call hierarchy
  • Polishing auto-import functionality (fixing issues, adding functionality)
    • Just expect more to come in.
  • Project references improvements
    • Opening unbuilt project reference solutions (git clone scenarios)
    • Delayed loading of projects (improving performance and memory consumption)

• Website and Documentation

  • New Handbook
    • Finishing up chapters (Enums and Modules) in core handbook
  • Redesign
    • Core messaging
    • Samples
    • New community page for meetups/conferences
    • Integrating the new handbook into the site
    • Ensure full accessibility

• Stability

  • TSServer crawler
    • Currently takes a fixed set of repos
      • That's fine.

• Performance

  • Rolling Issues
  • Experiments in Perf
    • Can we incrementally bind, reuse checking results, etc.?
  • Customer Development/Investigation
    • Establish hypotheses
    • Validate/invalidate
    • Concept/value testing
    • Implementation
  • Get performance data from TSServer crawler work.

   Thanks AnyhowStep and Anders Hejlsberg (@ahejlsberg). Additionally, I've made a change to the schedule. We will be reducing the feature period given that there's a convenient opportunity to align with Visual Studio, and we feel like the planned features are all individually in a good place.

   Does Auto-inserted await for completions and Call Hierarchy support on roadmap move to v3.7? It's not included in v3.6.3. right?

    Hey everyone - as you've all likely heard, TypeScript 3.7 is now available!

    As a few follow-ups:

    • We will likely have a 3.7.4 servicing release.
    • The Iteration Plan for TypeScript 3.8 is also now available: TypeScript 3.8 Iteration Plan #34898
    • The PRs asked about above will likely make it into 3.8.

    Thanks everyone!
