FLOCA

Enterprise-grade microservice architecture for NodeJS

========

floca is a complete solution to aid the development of enterprise-grade applications following the microservices architectural pattern. A proven stack used by numerous of systems in production for years now.

The basic idea of floca is to provide an abstraction level allowing your project to be freed of technical layers and unnecessary decoration. Your codebase will we required to define only pure CommonJS modules and all underlaying services will be set up by floca configured by a simple JSON object.

Features

• Proven, exceptionally featureful microservices architecture
• REST and Websockets as endpoints
• Internal services to be called by in-house entities only
• Tracking: you can monitor every message delivered (request or response) by only few lines of code
• Flow control / Reproducibility: A flow of communication / messages can be halted / continued / reinitiated anytime with no effort
• Advanced routing & listening: system fragmentation, qualified names, regular expressions, wildcards, etc.
• Channel-agnostic you can use any underlaying technology your application requires: AMQP, ZeroMQ, XMPP, etc...
• Built-in logging service supporting Loggly as well
• Short learning curve: no need to learn hundred of pages, communication has to be simple after all. CommonJS is all you need to understand. :)

System model

Of course, you can orchestrate your app the way you prefer, but please let us share a possible way to build up the codebase of an EE app using floca:

Each microservice

• has an own repository
• possesses only just a few CommonJS definition and optional configuration file(s)
• developed by a dedicated developer.
• is functional on its own. Can be built and deployed to a cloud provider or docker image with ease.

Your code is clean, pure and surprisingly simple.

Installation

$ npm install -g floca

Quick setup

Using the CLI tool:

$ floca create demoApp
$ cd demoApp
$ npm install
$ npm start

The CLI tool will create a new folder 'demoApp', and will create all required subfolders and files in it. By executing those npm commands, your microservice is ready-to-serve! The initial project will contain:

• a microservice
• a Starter code
• a preliminary package.json
• a sample config for the microservices

Creating own project:

var Floca = require('floca');

var floca = new Floca({
	entities: {
		appName: 'NameOfYourApp',
		serviceName: 'NameOfYourMicroService'
	}
});

floca.start( function(){
	console.log('Started.');
} );

Yes, it is that simple.

---

In either case, the app will

• read and watch your 'bus' folder and all entities defined in it
• publish entities and endpoints you defined
• be ready to serve :)
