• @nativescript/core package

  • Move all the code to @nativescript/core generate the tns-core-modules compatibility package

  • generate tests that validate that compatibility package exports all modules

  • Update developer workflow. There should be an easy way to setup the nativescript/nativescript repo so that you can run the tests and all e2e projects with linked modules and HMR.

  • Do a detailed review of the barrel exports:

    • @nativescript/core
    • @nativescript/core/ui
    • @nativescript/core/ui/layouts
    • Missing modules. Style, FormattedString etc.
      • Styling -> there are a couple of useful things from styling modules:
      • export { addTaggedAdditionalCSS, removeTaggedAdditionalCSS } from "./styling/style-scope";
      • export { Style } from "./styling/style";
      • FormattedString, Text, Span

  • Move methods exported by modules into static class-mehtods, thus eliminating the need of ns prefix-ed objects. Problematic modules:

    • Frame
    • Builder
    • ImageSource
    • Application
    • Application-settings
    • Connectivity
    • Http
    • Profiling
    • Trace
    • Utils
    • consider using namespaces where appropriate

  • Move modules into ui. Create re-exports on the original place for back-compat. Models that should be moved in ui:

    • FormattedString and Span

  • Handle EventDatas and clashing interfaces names. Try to define all event-data interfaces in one place only and reuse.

  • generate documentation (with typedoc) for the scoped packages.

    • Research if we can generate typedoc for barrel files (seems now that re-exported modules are not documented). Result: rollup d.ts generated with api-extractor.
    • Docs for functions re-exported inside objects (ex. Trace, Utils) are not visible in the docs.

  • Run the e2e/scoped-packages application on CI

• @nativescript/angular package

  • Move all the code to @nativescript/angular and create nativescript-angular compatibility package (either generate it or manually create it)
  • Update developer workflow. There should be an easy way to setup the nativescript-angular repo so that you can run the tests and all e2e projects with linked modules and HMR.

• nativescript-dev-webpack package

  • Remove the tns-core-module/xml dependency in the xml-namespace-loader
  • Make sure webpack works with the tns-core-modules compatibility package without the need to change configuration.
  • Make sure all generated code from webpack loaders uses the scoped packages. This way people won't have to still include the compat packages in their projects. Add a check that scoped-packages exist in the project and show "not compatible" error otherwise.

• nativescript-cli

  • ...

• Create an ESLint rule for migrating to scoped packages imports  #8131 Migration tool (eslint rule with auto-fix). It should:

  • convert all tns-core-modules imports to @nativescript/core imports
  • convert all nativescript-angular imports to @nativescript/angular imports
