Enabling TypeScript (ts-loader)

Want to use TypeScript? No problem! First, install the dependencies:

        1
        $ yarn add --dev typescript ts-loader
    

Then, activate the ts-loader in webpack.config.js:

        1
2
3
4
5
6
7
8
9
        // webpack.config.js
// ...

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

    .enableTypeScriptLoader()
;
    

That's it! Any .ts files that you require will be processed correctly. You can also configure the ts-loader options via a callback:

        1
2
3
4
        .enableTypeScriptLoader(function (typeScriptConfigOptions) {
    typeScriptConfigOptions.transpileOnly = true;
    typeScriptConfigOptions.configFile = '/path/to/tsconfig.json';
});
    

If React assets are enabled (.enableReactPreset()), any .tsx file will be processed as well by ts-loader.

More information about the ts-loader can be found in its README.

Faster Builds with fork-ts-checker-webpack-plugin

By using fork-ts-checker-webpack-plugin, you can run type checking in a separate process, which can speedup compile time. To enable it, install the plugin:

        1
        $ yarn add --dev fork-ts-checker-webpack-plugin
    

Then enable it by calling:

        1
2
3
4
5
6
        // webpack.config.js

Encore
    // ...
    .enableForkedTypeScriptTypesChecking()
;
    

This plugin requires that you have a tsconfig.json file that is setup correctly.
