Node.js Question

Importing node-modules with TypeScript

I'm trying to get this to work, but I can't seem to find a solution anywhere on SO. When trying to compile this single-file app:

import http = require('http')
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');


Using the command "tsc app.ts --module 'commonjs'" I get the following error (not using the --module flag gives me an additional error telling me that I need it to compile external modules):

error TS2071: Unable to resolve external module '"http"'.
error TS2072: Module cannot be aliased to a non-module type.

Answer

TypeScript needs to know that http is present. Follows these two steps
