Enabling TypeScript (ts-loader)

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

// webpack.config.js

  // ...
  Encore
      // ...
+     .addEntry('main', './assets/main.ts')

+     .enableTypeScriptLoader()

      // optionally enable forked type script for faster builds
      // https://www.npmjs.com/package/fork-ts-checker-webpack-plugin
      // requires that you have a tsconfig.json file that is setup correctly.
+     //.enableForkedTypeScriptTypesChecking()
  ;

Then create an empty tsconfig.json file with the contents {} in the project root folder (or in the folder where your TypeScript files are located; e.g. assets/). In tsconfig.json you can define more options, as shown in tsconfig.json reference.

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.

// webpack.config.js

      // ...
      .addEntry('main', './assets/main.ts')

-     .enableTypeScriptLoader()
+     .enableTypeScriptLoader(function(tsConfig) {
+         // You can use this callback function to adjust ts-loader settings
+         // https://github.com/TypeStrong/ts-loader/blob/master/README.md#loader-options
+         // For example:
+         // tsConfig.silent = false
+     })

          // ...
  ;

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.
