TypeScript loader for webpack

Usage

Installation

npm install ts-loader

Configuration

1. Add .ts as a resolvable extension.
2. Configure all files with a .ts extension to be handled by ts-loader.

module.exports = {
    entry: './app.ts',
    resolve: {
        extensions: ['', '.webpack.js', '.web.js', '.js', '.ts']
    },
    module: {
        loaders: [
            { test: /\.ts$/, loader: 'ts-loader?sourceMap&target=ES3' }
        ]
    }
}

Options

target

Specify the TypeScript output target.

• ES3
• ES5 (default)
• ES6

module

Specify the type of modules that TypeScript emits.

• CommonJS (default)
• AMD

sourceMap (boolean) (default=false)

Specify whether or not TypeScript emits source maps.

noImplicitAny (boolean) (default=false)

Specify whether or not TypeScript will allow inferring the any type.

compiler (string) (default='typescript')

Allows use of TypeScript compilers other than the official one. Should be set to the NPM name of the compiler.

additionalFiles (array of string) (default=[])

Allows additional files to be manually passed to the TypeScript compiler. For example, if you want to make a declaration file available without actually referencing it in code with a /// <references /> tag. Should consist of rooted paths.

instance (string)

Advanced option to force files to go through different instances of the TypeScript compiler. Can be used to force segregation between different parts of your code. Can typically be ignored.

Loading other resources and code splitting

Loading css and other resources is possible but you will need to make sure that you have defined the require function in a declaration file.

declare var require: {
    <T>(path: string): T;
    (paths: string[], callback: (...modules: any[]) => void): void;
    ensure: (paths: string[], callback: (require: <T>(path: string) => T) => void) => void;
};

Then you can simply require assets or chunks per the webpack documentation.

require('!style!css!./style.css');

React JSX

This loader supports using jsx-typescript. Simply install jsx-typescript and use the compiler=jsx-typescript option.

If for some reason using jsx-typescript doesn't work or you want to use the official TypeScript take a look at ts-jsx-loader.

Building from source

tsd reinstall
npm install
tsc index.ts --module commonjs
