Introduction to Kraken-JS

Kraken.js is a lightweight and powerful layer that extends the express framework by providing structure and conventions. It offers a wealth of features and middleware to help developers build scalable and maintainable Node.js applications.

Getting Started with Kraken-JS

To get started with Kraken.js, first install it via npm:

npm install kraken-js

Initialize your project with Kraken:

kraken init my-project

Configuration Management

Kraken.js utilizes a powerful configuration management system. Configuration files are placed in the config/ directory and are automatically loaded and merged based on the environment.

// config/development.json
{
  "port": 8000,
  "app": {
    "title": "Development App"
  }
}

Middleware

Kraken.js integrates deeply with Express middleware. You can add custom middleware or use built-in middleware:

var kraken = require('kraken-js');
var express = require('express');
var app = express();

app.use(kraken());

app.use(function (req, res, next) {
  console.log('Custom Middleware');
  next();
});

Router and Controllers

Kraken.js supports a controller-based routing system. Define your routes and controllers separately and map them in your main application file:

// controllers/home.js
exports.index = function(req, res) {
  res.send('Home Page');
};

// routes/index.js
module.exports = function (router) {
  var home = require('../controllers/home');
  router.get('/', home.index);
};

// index.js
var app = require('express')();
var kraken = require('kraken-js');
app.use(kraken({
  onconfig: function (config, next) {
    next(null, config);
  }
}));

app.listen(8000);

Security

Implemented security features within Kraken.js enhance the safety and protection of your application:

var lusca = require('lusca');

app.use(lusca.csrf());
app.use(lusca.xframe('SAMEORIGIN'));
app.use(lusca.hsts({ maxAge: 31536000 }));

Application Example

Here’s a complete example of a Kraken.js application using the aforementioned APIs:

var kraken = require('kraken-js');
var express = require('express');
var lusca = require('lusca');
var app = express();

app.use(kraken({
  onconfig: function (config, next) {
    next(null, config);
  }
}));

app.use(lusca.csrf());
app.use(lusca.xframe('SAMEORIGIN'));
app.use(lusca.hsts({ maxAge: 31536000 }));

app.get('/', function (req, res) {
  res.send('Welcome to Kraken.js App');
});

app.listen(8000, function () {
  console.log('Listening on port 8000');
});

With Kraken.js, you can build robust and structured applications with greater ease and security. The conventions and tools provided make development more manageable and streamline the workflow.
