TypeScript Webpack Loader

TypeScript loader for Webpack.

Example Configuration

webpack.config.js

``javascript
module.exports = {

// Currently we need to add '.ts' to resolve.extensions array.
resolve: {
extensions: ['', '.webpack.js', '.web.js', '.ts', '.js']
},

// Source maps support (or 'inline-source-map' also works)
devtool: 'source-map',

// Add loader for .ts files.
module: {
loaders: [
{
test: /\.ts$/,
loader: 'typescript-loader'
}
]
}
};
`

After that, you would be able to write JSX in TypeScript!

Best Practices

You can use typescript-loader together with
jsx-typscript compiler which
has support for JSX syntax (used in React.js).

For that you need to install jsx-typescript:

% npm install jsx-typescript

And specify typescriptCompiler loader option:

`javascript
module.exports = {

module: {
loaders: [
{
test: /\.ts$/,
loader: 'typescript-loader?typescriptCompiler=jsx-typescript'
}
]
}
};
`

The most natural way to structure your code with TypeScript and webpack is to use external modules, and these work as you would expect.

`
npm install --save react
`

`typescript
import React = require('react');
`

TypeScript Loader will work with internal modules too, however acquiring a reference to modules declared this way requires some work using the exports-loader. This is required because webpack wraps every file in a closure and internal modules are meant to run in a global context.

foo.ts
`typescript
module Foo {
export var bar = 42;
}
`

main.ts
`typescript
///
var foo: typeof Foo = require('exports?Foo!./foo');
console.log(foo.bar) // 42
