Forbin NPM | npm.io

Forbin.js

ES6 Component for controllers with filter support.

import Controller from "forbin";

const logRequest = Symbol(),
	authenticate = Symbol(),
	logResponse = Symbol();

class ApplicationController extends Controller {
	filters(...options) {
		this.before(this[logRequest]);
		this.before([this.changePassword, this.changeUsername], this[authenticate]);
		this.after(this.changePassword, this[logResponse]);
		this.skip(this.changePassword, this[logRequest]);
	}

	[logRequest](request, response, next) {
		//log request before every action on the controller
		next();
	}

	[logResponse](request, response, next) {
		//log response after some action
		next();
	}

	[authenticate](request, response, next) {
		//authenticate user
		next();
	}

	changeUsername(request, response) {
		//here the request is logged and the client authenticated
		//do your action and send the response
	}

	changePassword(request, response) {
		//here the client is authenticated but the log skipped
		//do your action and send the response
		//after this action the response will be logged
	}

	getInfo(request, response) {
		//here the request is logged but is a public operation
		//do your action and send the response
	}
}

Import / Require

import Controller from "forbin";

// ES5
var Controller = require("forbin");

// Require.js
define(["require"] , function (require) {
    var Controller = require("forbin");
});

Getting Started

Using it

You should extend the base Controller provided within forbin in order to apply filters and take advantage of the provided functionality.

As the above example shows, you can define a specific filter to every action on the controller, to a specific one, or to an array of actions.

There are three filter functions available right now:

before
after
skip

All those functions share the same interface:

before(filterToApply); //this will apply a before filter to all actions
before(functionToApplyTheFilterTo, filterToApply); //this will apply a before filter to a specific action
before(arrayOfFunctionsToApplyTheFilterTo, filterToApply); //this will apply the filter to the provided array of actions

after(filterToApply); //this will apply an after filter to all actions
after(functionToApplyTheFilterTo, filterToApply); //this will apply an after filter to a specific action
after(arrayOfFunctionsToApplyTheFilterTo, filterToApply); //this will apply the filter to the provided array of actions

skip(filterToApply); //this will skip a filter on all actions
skip(functionToApplyTheFilterTo, filterToApply); //this will skip a filter on a specific action
skip(arrayOfFunctionsToApplyTheFilterTo, filterToApply); //this will skip the filter on the provided array of actions
