bitcoinaddress.js

If you need to take Bitcoin payments on your site, then bitcoinaddress.js (GitHub: miohtama / bitcoinaddress.js, License: MIT, npm: bitcoinaddress) by Mikko Ohtamaa might help. It’s a module for handling Bitcoin payments. It can be run as a client-side script, or as a Node module. It allows Bitcoins to be sent, or specific currency amounts based on “fiat” amounts.

It’s based around bitcoin: URIs, and allows you to display “Pay from wallet” links on your pages. It also displays QR codes so people can easily make payments using mobile Bitcoin apps.

atry

atry (GitHub: CodeCharmLtd / atry, License: MIT, npm: atry) from Code Charm (Damian Kaczmarek) is an alternative to Node’s domain module. The basic idea is to allow exceptions to be caught using an asynchronous API:

atry(function() {
  setTimeout(function() {
    throw new Error('I am Error');
  }, 10);
}).catch(function(err) {
  console.log('Error:', err);
});

It has an intercept method that returns an “exception safe” callback that you can pass as a callback to asynchronous APIs like fs.readFile.

Node Web Modules

Node Web Modules (GitHub: caio-ribeiro-pereira / node-web-modules, License: MIT) by Caio Ribeiro Pereira is a Node web application that shows a list of popular web frameworks for Node. If you select one of the modules it shows a screenshot and some statistics.

The project is powered by Express and Redis, and it uses the GitHub API. The module list it displays on http://nodewebmodules.com/ is useful for beginners, but you might also like to take a look at the source to see how it works.
