aioc

Another inversion of control (IoC) container for Node.js applications inspired by the awesome compact-ioc.

Installation

npm install aioc --save

Example usage

// foo.js
class Foo {
  sayFoo () {
    console.log('foo')
  }
}
exports = module.exports = Foo
exports['@factory'] = () => new Foo

// bar.js
class Bar {
  sayBar () {
    console.log('bar')
  }
}
exports = module.exports = Bar
exports['@factory'] = () => new Bar

// foobar.js
class Foobar {
  constructor (foo, bar) {
    this.foo = foo
    this.bar = bar
  }
  sayFoobar () {
    this.foo.sayFoo()
    this.bar.sayNar()
  }
}
exports = module.exports = Foobar
exports['@deps'] = ['foo', 'bar']
exports['@factory'] = ([foo, bar]) => new Bar(foo, bar)

// ioc.js
const AIOC = require('aioc')
 
module.exports = new AIOC()
  .pub('foo', './foo')
  .pub('bar', './bar')
  .pub('foobar', './foobar')

// index.js
const ioc = require('./ioc')
 
const foobar = ioc.get('foobar')
 
foobar.sayFoobar()
 
// $ node index.js
// foo
// bar

}
exports = module.exports = Foo
exports['@factory'] = (deps, args) => new Foo(args)
 
// index.js
const ioc = new AIOC
 
ioc.pub('foo', './foo')
ioc.applyArgs('foo', ['foo', 'bar'])
 
const Foo = ioc.get('foo')
 
// $ node index.js
// ['foo', 'bar']
