What Changed?

This is a major release with 💥 breaking changes 💥! However, most apps will compile with minimal (or no) changes! 🎉 They'll also tend to compile much faster in many cases. ⚡️

We now use Babel 7's support for TypeScript to build apps and addons. Most of the horrible hacks we had to do before are now gone, and the error outputs you will see for type errors are much nicer as well. (As a particular note, we should work better with ember-auto-import now, since we're just part of the normal Broccoli/Babel pipeline Ember CLI uses.)

THIS IS A BETA! Please test this out in your apps! Please do not use this for your production apps!

Added ⭐️

• Much nicer reporting of type errors both in the console and in your browser
• Type errors now use the "pretty" type error format stabilized in TypeScript 2.9

Changed 💥

• We now build the application using Babel 7's TypeScript plugin. This has a few important limitations – some of them bugs (linked below); others are conscious decisions on the part of Babel. The changes:

  • const enum types are unsupported. You should switch to constants or regular enums.

  • trailing commas after rest function parameters (function foo(...bar[],) {}) are disallowed by the ECMAScript spec, so Babel also disallows them.

  • re-exports of types have to be disambiguated to be types, rather than values. Neither of these will work:

    export { FooType } from 'foo';
    

    import { FooType } from 'foo';
    export { FooType };
    

    In both cases, Babel attempts to emit a value export, not just a type export, and fails because there is no actual value to emit. You can do this instead as a workaround:

    import * as Foo from 'foo';
    export type FooType = Foo.FooType;
    

  • this types in ES5 getters and setters are do not work (babel/babel#8069)

  • destructuring of parameters in function signatures currently do not work (babel/babel#8099)

  Other bugs you should be aware of:

  • if an enum has a member with the same name as an imported type (babel/babel#8881), it will fail to compile

• ember-cli-typescript must be in dependencies instead of devDependencies for addons, since we now hook into the normal Broccoli + Babel build pipeline instead of doing an end-run around it

• Addons can no longer use .ts in app, because an addon's app directory gets merged with and uses the host's (i.e. the other addon or app's) preprocessors, and we cannot guarantee the host has TS support. Note that in-repo-addons will continue to work for in-repo addons because of the app build works with the host's (i.e. the app's, not the addon's) preprocessors.

• Apps need to use .js for overrides in app, since the different file extension means apps no long consistently "win" over addon versions (a limitation of how Babel + app merging interact) – note that this won’t be a problem with Module Unification apps

Fixed 🔧

• Type errors now show properly in the browser when running tests

This release says bye to compilation churn, bye to spurious rebuilds and errors, and bye to relaxed TypeScript checks by default. Great efforts were made to get Broccoli and the TypeScript compiler "NSYNC".

Note: As of this release, re-running the blueprint on an existing project (e.g. ember generate ember-cli-typescript) will update tsconfig.json with maximum compiler strictness settings, which are likely to result in new TypeScript errors being reported. You can always turn these checks off individually, but they are now on by default.

What Changed?

Added

• This addon now supports failing the build when there are type errors, using noEmitOnError: true in tsconfig.json.

Changed

• Clarified instructions for sourcemaps.

Fixed

• TypeScript no longer churns on every change in the tmp directory.
• Make sure ember-cli-typescript is a dev dependency when generating in-repo-addons, so their TypeScript gets built correctly.
• Eliminated some lint errors in the build.
• Synchronization between tsc and the broccoli build process has been improved, reducing spurious rebuilds (and works properly on Windows).
• Updated the generated tsconfig.json to use the maximum strictness we can with Ember's typings.
• Simplified the file watching implementation, fixing some odd behavior when trees of files were deleted or moved all at once.
