TypeScript Deep Dive
TypeScript with NodeJS
TypeScript has had first class support for NodeJS since inception. Here's how to get setup with a NodeJS project in
TypeScript:
1. Compile with --module set to "commonjs" (as we mentioned in modules)
2. Compile with --declaration set to true . This gets TypeScript to generate a .d.ts file which is what TypeScript looks
for in your node_modules for using TypeScript NPM modules from other TypeScript modules.
3. Add node.d.ts ( tsd install node ) to your compilation context.
That's it! Now you can use all the built in node modules (e.g. import fs = require('fs') ) with all the safety and developer
ergonomics of TypeScript!
You can even use other node modules written in TypeScript (e.g. npm install csx for csx usage: import csx =
require('csx') ). One trick here is that you might want to have a typings field (e.g. src/index ) in your package.json similar
to the main field to point to the default TypeScript definition export.
