Project to build better microservices.

This repository contains ilms and few plugins.

A service is a group of middleware. A middleware is a handler which, with a given input give a output ;

• basic example

const ilms = require('ilms');

const sum = (params, next) => {
  next(params.a + params.b);
};

ilms('sum')
    .use(sum)
    .run({ a : 5, b: 4 })
    .then(result => {
      expect(result).to.be.equal(9);
    });

• multiple middlewares in one service :

const ilms = require('ilms');

const registerUserMongoDB = require('./registerUserMongoDB');
const registerUserElasticSearch = require('./registerUserElasticSearch');
const triggerCRM = require('./triggerCRM');

ilms('users.register')
    .use(registerUserMongoDB)
    .use(registerUserElasticSearch)
    .use(triggerCRM);

• call a service ;

const ilms = require('ilms');

ilms.run('users.get', { _id: 33 })
    .then(user => {
      // Do something
    });

• The project give a way to write buisness logic.
• This kind of handler is easier to test.
• The way to separe logic is easier to understand.

### API - ilms

• ilms.declare(serviceName) : Create a new service from serviceName.
• ilms.exists(serviceName) : Check if the given service exists
• ilms.run(serviceName, params) : Play a service with the given params.
• ilms.get(serviceName) : Get the service serviceName

• Service.use(middleware) : Associate a middleware to the given service.
• Service.bind(serviceName) : Associate the current service with another service
• Service.run(params) : Play the service and return a promise with the result.

### API - next

• next(results) : go to the next middleware in the stack or resolve middleware stack
• next.resolve(results) : resolve the middleware stack
• next.reject(err) : reject the middleware stack
• next.replay(params) : replay the same middleware with the params
• next.run(serviceName, params) : play another service (return a promise)
