TypeScript Using Typescript with React (JS & native) Typescript & react & webpack
Example
Installing typescript, typings and webpack globally
npm install -g typescript typings webpack
Installing loaders and linking typescript
npm install --save-dev ts-loader source-map-loader npm link typescript
Linking TypeScript allows ts-loader to use your global installation of TypeScript instead of needing a separate local copy typescript doc
installing .d.ts files with typescript 2.x
npm i @types/react --save-dev
npm i @types/react-dom --save-dev
installing .d.ts files with typescript 1.x
typings install --global --save dt~react
typings install --global --save dt~react-dom
tsconfig.json configuration file
{
"compilerOptions": {
"sourceMap": true,
"noImplicitAny": true,
"module": "commonjs",
"target": "es5",
"jsx": "react"
}
}
webpack.config.js configuration file
module.exports = {
entry: "<path to entry point>",// for example ./src/helloMessage.tsx
output: {
filename: "<path to bundle file>", // for example ./dist/bundle.js
},
// Enable sourcemaps for debugging webpack's output.
devtool: "source-map",
resolve: {
// Add '.ts' and '.tsx' as resolvable extensions.
extensions: ["", ".webpack.js", ".web.js", ".ts", ".tsx", ".js"]
},
module: {
loaders: [
// All files with a '.ts' or '.tsx' extension will be handled by 'ts-loader'.
{test: /\.tsx?$/, loader: "ts-loader"}
],
preLoaders: [
// All output '.js' files will have any sourcemaps re-processed by 'source-map-loader'.
{test: /\.js$/, loader: "source-map-loader"}
]
},
// When importing a module whose path matches one of the following, just
// assume a corresponding global variable exists and use that instead.
// This is important because it allows us to avoid bundling all of our
// dependencies, which allows browsers to cache those libraries between builds.
externals: {
"react": "React",
"react-dom": "ReactDOM"
},
};
finally run webpack or webpack -w (for watch mode)
Note: React and ReactDOM are marked as external
