IOC Library

Inversion of control library for JavaScript/TypeScript.

Developer API inspired by PHP-DI.

License info, please see LICENSE.md.

Example Usage:

import { Builder } from 'ioc/dist/builder.js';
import { ElementFlat} from 'ioc/dist/types.js';
import { Container } from 'ioc/dist/container.js';
import { DBConnection } from './db-connection.js'; // your class dependency
import { Entity } from './entity.js'; // your class service

const items = [
    {
        identifier: 'db_host',
        value: '127.0.0.1'
    },
    {
        identifier: 'db_user',
        value: 'root'
    },
    {
        identifier: 'db_pass',
        value: 'example'
    },
    {
        identifier: 'DBConnection',
        value: (c) => { 
            return new DBConnection(c.get('db_host'), c.get('db_user'), c.get('db_pass'))
        }
    },
    {
        identifier: 'Entity',
        value: (c) => {
            return new Entity(c.get('DBConnection'))
        }
    }
];

const builder = new Builder();
builder.addDefinitions(items);
const container = builder.getContainer();
const entity = container.get('Entity');

Alternatively with Static Factory:

...
import { Factory as IOCFactory } from 'ioc/dist/factory.js';

const items = [
    ...
];

// stores container singleton
let container = IOCFactory.getContainer(items); 

// called later on in your code
container = IOCFactory.getContainer(); 

// add additional items to container
container = IOCFactory.getContainer([ ... ]);
