TypeScript-Babel application

Mininal example for babel-plugin-rewire does not work in a Typescript project at StackOverflow

This is a example that uses Babel to transform TypeScript to plain JavaScript, and uses TypeScript for just type-checking. It is recommended to be set via @babel/cli. Babel looks for .js files by default, but this is not configurable withn the Babel config file.

Commands

  • npm run check-types - check types for TypeScript.
  • npm run lint - run the TypeScript linter using the tslint.json config file.
  • npm run compile - compile the ES6 TypeScript into the /lib directory.
  • npm test - run the tests using the local .mocharc.json config file. Babel Config set is inside babel.config.js.

Handling Babel extensions

Compiling TS + Babel

By specifying --extensions ".ts, .tsx" options, @babel/cli can handle .ts, .tsx files.

Testing TS + Babel with Mocha

According to this issue, you have to create a new js file babel-register.js into the test directory, specify extensions for TypeScript. This cannot be done by just using --require @babel/register.
