Welcome to the Comprehensive Guide on Kraken-js

Kraken-js is a secure and scalable layer that extends Express by providing structure and convention. It is used to create advanced Node.js applications with confidence and ease!

Getting Started

Kraken-js is built on top of Express, providing additional structure and configuration capabilities. Below is a step-by-step guide to setting up your first Kraken-js application.

  
  const express = require('express');
  const kraken = require('kraken-js');
  const app = express();
  
  app.use(kraken());
  
  app.listen(3000, function () {
    console.log('Your Kraken-js application is running on port 3000');
  });
  

API Examples

Config API

Kraken-js offers a powerful configuration API. You can set different configurations for different environments.

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

  const options = {
    onconfig: function (config, callback) {
      // Customize the config object
      callback(null, config);
    }
  };

  app.use(kraken(options));
  

Middleware API

Just like Express, you can use middleware in Kraken-js.

  
  const express = require('express');
  const kraken = require('kraken-js');
  const app = express();
  
  app.use(kraken());
  app.use((req, res, next) => {
    console.log('Middleware executed.');
    next();
  });
  
  app.get('/', (req, res) => {
    res.send('Hello Kraken-js');
  });
  
  app.listen(3000);
  

Router API

Kraken-js allows you to structure your routes easily and in an organized manner.

  
  const express = require('express');
  const kraken = require('kraken-js');
  const app = express();
  
  const router = express.Router();
  
  router.get('/users', (req, res) => {
    res.send('User List');
  });
  
  app.use(kraken());
  app.use('/api', router);
  
  app.listen(3000);
  

Full Application Example

Below is a complete example demonstrating the usage of Kraken-js with the configurations and APIs we have introduced.

  
  const express = require('express');
  const kraken = require('kraken-js');

  const app = express();

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

  const router = express.Router();
  router.get('/users', (req, res) => {
    res.send('User List');
  });

  app.use((req, res, next) => {
    console.log('Global Middleware Executed');
    next();
  });

  app.get('/', (req, res) => {
    res.send('Hello Kraken-js');
  });

  app.use('/api', router);

  app.listen(3000, function () {
    console.log('Your Kraken-js application is running on port 3000');
  });
  

With Kraken-js, building structured and manageable applications becomes more straightforward. Happy coding!
