These files appear to have been missed in the update of test file naming from actual/expected.js to input/output.js. As a result, they were silently not being run. I've confirmed that they were not running, updated the names, then confirmed that they are running now.
@babel/plugin-transform-typescript
Transform TypeScript into ES.next.
Does not type-check its input. For that, you will need to install and set up TypeScript.
Caveats
- Does not support
namespaces. Workaround: Move to using file exports, or migrate to using themodule { }syntax instead. - Does not support
const enums because those require type information to compile. Workaround: Remove theconst, which makes it available at runtime. - Does not support
export =andimport =, because those cannot be compile to ES.next. Workaround: Convert to usingexport defaultandexport const, andimport x, {y} from "z".
Example
In
const x: number = 0;
Out
const x = 0;
