flexi-container

Flexible container for services that separates implementation and usage from configuration.

flexi-container create services using provied plugin while the default plugin, ObjectContaier, create the service in memory.

Supported Plugins

flexi-container-socket - socket.io plugin

Installion

npm install --save flexi-container

Usage

Firts thing we need to create a Contract for our service that the service will implement and the consumer will use:

// math-contract.js
const Contract = require('flexi-container').Contract;

module.exports = new Contract({
    add: Contract.Function,
    sub: Contract.Function
});

Contract's members can be either Contract.Function or Contract.Event. When members is a Contract.Event, the method will be exposed to the concrete class.

our service just implement a class with the same members

// math.js
class Math {
    add(a,b) {
        return a + b;
    }
    sub(a,b) {
        return a -b;
    }
}

to register the service in the container we'll call registerService(contract, implementation, [plugin]) and to use the service a call getService(contract, [plugin])

const flexiContainer = require('flexi-container');
const mathContract = require('./math-contract');
const Math = require('./math');

flexiContainer.registerService(mathContract, new Math());
const math = flexiContainer.getService(mathContract);

console.log(math.add(1,2));
console.log(math.sub(10,5));
