Correct way to reference modules from other modules in Typescript

Question

I\'m writing a module for NodeJS in Typescript. I\'m trying to process a request (which should be an IncomingMessage object) using this module.

Answer 1

If you are writing a module, nothing you write is in the global scope - the file itself is a module, and everything inside it is scoped to that module.

import http = require('http');

export function processRequest(req : http.IncomingMessage) : boolean {
    return false;
};

In the example above, the file, rateLimiter.ts is the module. http is imported into the rateLimiter module.

You need to compile with the module flag - for example:

tsc --module commonjs rateLimiter.ts

Most editors and IDEs supply a way to set this too.
