Use the non-DOM parts of ExtJS (Ext Core + Ext.data currently) server-side with Node.js

branch: master
README.md

What is N-Ext ?

N-Ext is the compression of Node and Ext. Its purpose is to allow developpers to use the ExtJS 4 Javascript framework in a server-side environment using Node.js.

Features

The project provides:

  • Ext.core without the client-side-specific parts
  • The Dynamic class loading package
  • Ext.data package
  • Provides a proxy for MongoDB that can be used with the classes from Ext.data. The proxy uses the excellent node-mongodb-native adapter
  • Examples available
  • A developer who is all-ears to requests and comments!

How to use it

Note:

  • N-Ext can not (as of now) use packaged version of ExtJS. It provides a minimal subset of ExtJS in which the DOM-specific code has been removed.
  • The only requirement to have N-Ext workin is the module contained in the node_modules folder. The lib folder contains the whole Ext package and the MongoDB proxy and store.

Set up N-Ext:

  1. Download the latest version of ExtJS 4
  2. Unzip the src folder in %PROJECT_ROOT%/lib/Ext (this can be changed with a single line of code)
  3. In the main file (it can be any file) of your application, type the following:

    var sencha = require('n-ext');
    sencha.bootstrapCore();
    

And that's it! You now have the beloved Ext namespace available application-wide.

Documentation

A little (but growing) documentation is available at the Wiki.

FAQ

  • What is the point of the project ?

Fun! Seriously, there is of course a serious reason to that (although fun is a big part of the game). The point is that with ExtJS (which I love), client-side coding carries its share of the model, of the application, and I was bored to have to code two equivalent models in both the server and the model, but with 2 different languages. It meant twice the amount of coding, more than twice the amount of unit testing and a world of troubles.

So I plunged into Node.js and started coding N-Ext, hoping to have a consistent framework to work on and with throughout the apps I developed.

  • Why does the Ext namespace have to be global to the app ?

I agree this is counter-intuitive in regards to the CommonJS conventions, but this is a limitation due to the way the Ext namespace is constructed and its packages are self- and inter-referencing through the namespace. I've worked a little on sandboxing the Ext namespace and having it in the exports variable of the module, but to no avail yet.

On the other hand, the package is supposed to be used throughout the whole app, so I'm still wondering whether it is absolutely required or just more normative.
