Sapphire IOC

This is a simple IOC container implementation on NodeJS. You can register services on it and retrieve it later.

Register with bind

You can register a service using the bind method and passing a callback on how the service should build when is accessed later. The IOC container will always create a new instance when the ioc.make() is executed.

// SimpleClass.js
class SimpleClass {
    constructor(parameter) {
        this._parameter = parameter
    }
 
    getParameter() {
        return this._parameter
    }
 
    setParameter(parameter) {
        this._parameter = parameter
    }
}
 
module.exports = SimpleClass

const IOC = require('sapphire-ioc')
const SimpleClass = require('./SimpleClass.js')
 
let ioc = new IOC()
ioc.bind(SimpleClass, () => (
    new SimpleClass(5)
))
const simpleClass = ioc.make(SimpleClass)

Register with singleton

const IOC = require('sapphire-ioc')
const SimpleClass = require('./SimpleClass.js')
 
let ioc = new IOC()
ioc.singleton(SimpleClass, () => (
    new SimpleClass(5)
))
const simpleClass = ioc.make(SimpleClass)
const simpleClass2 = ioc.make(SimpleClass)
 
simpleClass.setParameter(3)
simpleClass2.getParameter()     // 3
