Enabling TypeScript (ts-loader)

Enabling TypeScript (ts-loader)

Want to use TypeScript? No problem! First, enable it:

  1.   // webpack.config.js
  3.   // ...
  4.   Encore
  5.       // ...
  6. +     .addEntry('main', './assets/main.ts')
  8. +     .enableTypeScriptLoader()
  10.       // optionally enable forked type script for faster builds
  11.       // https://www.npmjs.com/package/fork-ts-checker-webpack-plugin
  12.       // requires that you have a tsconfig.json file that is setup correctly.
  13. +     //.enableForkedTypeScriptTypesChecking()
  14.   ;

Then restart Encore. When you do, it will give you a command you can run to install any missing dependencies. After running that command and restarting Encore, you’re done!

Any .ts files that you require will be processed correctly. You can also configure the ts-loader options via the enableTypeScriptLoader() method.

  1.   // webpack.config.js
  2.   Encore
  3.       // ...
  4.       .addEntry('main', './assets/main.ts')
  6. -     .enableTypeScriptLoader()
  7. +     .enableTypeScriptLoader(function(tsConfig) {
  8. +         // You can use this callback function to adjust ts-loader settings
  9. +         // https://github.com/TypeStrong/ts-loader/blob/master/README.md#loader-options
  10. +         // For example:
  11. +         // tsConfig.silent = false
  12. +     })
  14.           // ...
  15.   ;

See the Encore’s index.js file for detailed documentation and check out the tsconfig.json reference and the Webpack guide about Typescript.

If React is enabled (.enableReactPreset()), any .tsx file will also be processed by ts-loader.
