NodeJS in Action - 1

Node.js is an event-driven, server-side JavaScript environment. Node runs JavaScript using the V8 engine developed by Google for use in their Chrome web browser.  The major speed increase is due to the fact that V8 compiles JavaScript into native machine code, instead of interpreting it or executing it as bytecode. http://blog.modulus.io/top-10-reasons-to-use-node

Node.js way: synchronous.

To perform a filesystem operation you are going to need the fs module from the Node core library. To load this kind of module, or any other "global" module, use the following incantation:

var fs = require('fs')

Now you have the full fs module available in a variable named fs. All synchronous (or blocking) filesystem methods in the fs module end with 'Sync'. To read a file, you'll need to use fs.readFileSync('/path/to/file'). This method will return a Buffer object containing the complete contents of the file.

Node.js way: asynchronous.

Instead of fs.readFileSync() you will want to use fs.readFile() and instead of using the return value of this method you need to collect the value from a callback function that you pass in as the second argument.

Remember that idiomatic Node.js callbacks normally have the signature:

                function callback (err, data) { /* ... */ }

Also keep in mind that it is idiomatic to check for errors and do early-returns within callback functions.

Node.js module

Create a new module by creating a new file that just contains your directory reading and filtering function. To define a single function export,

you assign your function to the module.exports object, overwriting what is already there:

module.exports = {

    foo: function () {

        console.log("foo is here.");

    },

    bar: function () {

        console.log("bar is here.");

    }

};

To use your new module in your original program file, use the require() call in the same way that you require('fs') to load the fs module. The only difference is that for local modules must be prefixed with './'. The '.js' is optional here and you will often see it omitted. So, if your file is named mymodule.js then

var mymodule = require('./mymodule.js')
