After one month of hacking around with Node.js, I created and distributed my first package. NPM is the repository of all kind packages that you can think of. At this moment, there are 28 698 packages in NPM which is a lot for a 4 years old project. The philosophy of Node and its community is to keep the core tiny and encourage composition with small modules that do one thing well.
In that sense, I wrote a small facebook API client that I called tiny-facebook-wrapper, as you can see in the figure. The package.json and .npmignore are two important files to have in any Node.js package. In a nutshell, the first one is the descriptor of your package with the author, version, dependencies, etc. The second one is used for keeping off things that you don’t want to share in your package, such as, docs, tests(?) or other superfluous files. Don’t forget to document your package in a README file with some hands-on examples of how developers can use your software, they will thank you from the bottom of their hearts.
Now that I have my module ready to share, I can create a dev account in the NPM registry directly from the command line:
$ npm adduser
$ Username: davidcunha
$ Password: ********
$ Email: email@example.com
Publish the module:
$ npm publish
And that’s all folks, my small facebook API client is online for the community to use it:
