Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 400,000 packages pre-installed, including nano-server with all npm packages installed. Try it out:

nano-server lists no main file and has no index.js, so it can't be directly required. If this is a mistake, please let us know. It may however contain internal files that you can require manually:

// require("nano-server/[??]")

nano-server v0.5.4

An ultra-lightweight node.js HTTP server for web development.


nano-server is an ultra-lightweight node.js HTTP server for web development. It exposes a local directory through HTTP, simplifying development of front-end apps that require functionality blocked by cross-origin protections, e.g. AJAX, Canvas Image Processing, Web Audio Analysis, WebGL textures.

nano-server provides some features that I didn't find in similar server packages:

  • Sends gzipped versions of files, if they are available.
  • Attempts to set the Content-Type header with the appropriate MIME type for browser-relevant file types.
  • 0 dependencies. Can be dropped into any project.


The simplest way to install nano-server is as a global install through npm:

  $ npm install -g nano-server

Then nano-server can be invoked as a command line executable:

  $ nano-server

By default, nano-server will run on port 5000 and use the current working directory as its document root. Optionally, a port number can be passed as first argument on the command line:

  $ nano-server 3000

The document root can be given as second argument, if desired.

  $ nano-server 5000 my_app/public_html

Since nano-server has no dependancies, it can be dropped directly into any project and invoked using node explicitly. This can be useful if you don't have the necessary permissions to do a global install on the machine you're using:

  $ cp nano-server ~/path/to/project/
  $ cd ~/path/to/project/
  $ node nano-server
