Minutes

• Announcements

  • fdc3-dotnet 2.1.0 release: https://github.com/finos/fdc3-dotnet/releases/tag/v2.1.0
  • @bingenito reports that .NET 2.2 work has begun
    • proposed signatures (non-intent/context) event listeners (#1441)
    • Other work will be guided by the FDC3 CHANGELOG
  • API conformance test definitions are to be added to the documentation (#1417)
    • When adding to the API in future, PRs should ideally include any updates to conformance tests that are needed
    • Draft 2.2 conformance test additions are open for review (#1426)
  • FDC3 for Web Browsers implementation work is ongoing and active, a complete draft will soon be open for review and testing
    • The deprecation of the fdc3Ready() function from methods.ts and replacement by getAgent() was noted
    • ES6/Common.js: Whether to continue publishing is still an open question.
    • ES6 is still problematic when running tests with Jest (ES6 support is experimental), applications with legacy builds and legacy backend systems
    • One way to proceed would be to publish separate ES6 and Common.js modules - that will provide us with statistics on usage to compare - allowing the common.js version to be retired when it is no longer in use. The mono-repo structure introduced in the fdc3-for-web-impl PRs makes that easier to do.

• FDC3 for Web Browsers

  • Implementation work
    - Fair bit of implementation work is happening.
    - Giles is working on typescript types, type guards, validation function, better unions. This has been merged into the implementation PR.
    - Implementation is being aligned with the spec.
    - Prettier/ESLint need to be added.
    - Julianna has added reference UIs. Rob has also worked on the reference UIs.
    - Remaining work is to make this a well-documented, high-quality code base.
    - Implementers agreed that once more PRs go in (Kris'), it will be ready for code review.
    - We may not get Rob's time starting next year.
    - Upcoming: looking to recruit reviewers for the typescript code base.
    - Expect an announcement soon
    - The PR also refactors the FDC3 repository to be a monorepo to better support current and future component projects.

• minutes TBC

Action Items

• ...

Rolled over from previous meetings:

• FDC3 maintainers and interested contributors to revisit CommonJs vs ES6 #1351 as it should continue to be possible to publish a combined CommonJS and ES6 module, or to raise an alternative proposal.
• @finos/fdc3-maintainers Update the proposal for Support for Multiple Application Scopes (Agents) within a single window process #1250 to include a tear-down function for 'subAgents'.
• @kriswest add Add property to support analytics across apps #1290 to a future meeting agenda to determine what solution to select for the 2.3 scope
• @bingenito create an issue and PR to add the advice about consistent use of pascal case in enums in the API (implementation language and context docs (The Context Interface section after advice on union types).
