Ferrum [alfa]

What is it?

Ferrum is simple and powerful framework for node.js. It's designed for quick and simple development of high-performance application. Ferrum don't force you to organize your code how it wants - it's up to you and i suppose it gives some flexibility in development of apps.

Instalation

npm install ferrum

Hello, word

Here is an example of Ferrum app:

var util = require('util');
var ferrum = require('ferrum');

function MainHandler () {
    ferrum.RequestHandler.call(this);
    
    this.get = function () {
        this.write("Hello, world!");
    };
}

util.inherits(MainHandler, ferrum.RequestHandler);

ferrum.Application({
    routes: {
        '^/$': MainHandler
    }
}).run();

Then type http://localhost:8888 in browser address bar and enjoy.

Usage

• Request handlers and arguments
• Query params

Request handlers and arguments

In Ferrum application every URL or URL expression corresponds to handler based on ferrum.RequestHandler. This handler contains methods for processing GET, POST and others of http requests.

Allowed http-methods and appropriate ferrum methods are:

• GET > get()
• POST > post()
• PATCH > patch()
• PUT > put()
• DELETE > del()
• HEAD > head()
• OPTIONS > options()

In following example the root path / points to MainHandler and the URL expression /user/([0-9]+) to UserHandler. Apart of that regular expression groups are passed as arguments to UserHandler handler.

function MainHandler () {
    ferrum.RequestHandler.call(this);
    
    this.get = function () {
        ...
    };
}
util.inherits(MainHandler, ferrum.RequestHandler);


fuction UserHandler () {
    ferrum.RequestHandler.call(this);
    
    this.get = function (userId) {
        ...
    };
}
util.inherits(UserHandler, ferrum.RequestHandler);

ferrum.Application({
    routes: {
        '^/$': MainHandler,
        '^/user/([0-9]+)$': UserHandler
    }
}).run();

Query params

To work with query paramenters ferrum use third-party component qs. The result of parsing query string is available in ferrum.Request object.

// GET http://localhost/params?params1=value1&params2=value2

function ParamsHandler, () {
    ferrum.RequestHandler.call(this);
    
    this.get = function () {
        this.write(JSON.stringify(this.request.query));
        // => {"params1":"value1","params2":"value2"}
    };
}
util.inherits(ParamsHandler, ferrum.RequestHandler);

ferrum.Application({
  routes: {
    	'^/params$': ParamsHandler
	}
}).run();
