express-sticker

Group your express routes to access them globally and save the routes path in a configuration file

Getting Started

Group your express routes to access them globally from all your application and save the routes path in a configuration file. You can add dependencies in order to structure your code correctly. Check the usage examples to see how it's working.

npm install express-sticker

Usage examples

Initialization of the sticker

var express = require('express');
var app = express();
var sticker = require('../lib/index.js')(app);

Initialization of the routes file, possibility to add multiple files Possibility to pass params to the routes file.

var params = {prod: true};
var err = sticker.addRoutes(__dirname + '/routes.js', params);

Routes file example:

module.exports = function(params) {
    return [{action: 'get', path: '/user', stick: 'displayUser'},
            {action: 'get', path: '/wall', stick: 'displayWall'},
            {action: 'get', path: '/admin', stick: 'displayAdmin', enabled: params.prod}];
}

Creation of the sticks

• Every sticks must call next(error, params) at the end of its execution.
• The params of all the dependencies are merged in one object.
• If there is an error in the dependencies, the execution of the dependencies is stopped and the main stick is called with the error in req.err.
• It's possible to override a stick who is using res.end(), its res.end() will be ineffective but yours will work.

var stick = sticker.stick;

stick('checkLogin', function(req, res, next) {
    next(null);
});

stick('checkAvailability', function(req, res, next) {
    next(null);
});

var fetchUserData = stick('fetchUserData', ['checkLogin', 'checkAvailability'], function(req, res, next, params) {
    next(null, {user: 'jack'});
});

stick('displayUser', [fetchUserData], function(req, res, next, params) {
    if (req.error)
        res.end('error');
    else
        res.end(params.user);
    next(true, params);
});

stick('overrideDisplayUser', ['displayUser'], function(req, res, params) {
    res.end();
    next(null, params);
});

Using a variable in the dependencies array is better because faster, express-sticker doesn't have to look for the stick id but both practises are working.

Get a stick and execute it

var myStick = sticker.stick('displayUser');
sticker.execute(stick);
