• name - service name
• classOf - service class
• factory - service factory function
• args - array of service constructor or factory arguments
• tags - service tags (array of strings)
• shared - is the service shared or every time should be instantiated
• instance - instance of service target

DI

class DI {
    has(name)
    get(name, args)
    set(name, instance, options) {
    injectService(target, serviceName)
    register(name, options)
    find(callback)
    findFirst(callback)
    resolveService(service, args)
    resolveArg(arg)
    services
}

createService(name, options) - creates service from provided arguments

var service = DI.createService('myService', {classOf: Array, args: [[1,2,3,4,5]], tags: ['array']});

injectService(target, serviceName) - proxify target properties starts from $ sign to service getter

var target = {$myService: null};
DI.injectService(target, 'myService');
console.log(target.$myService); // [1,2,3,4,5]

has (name) - returns true if service exists register (name, options) - register new service with name and options set (name, instance, options) - set service with name name provided instance and options get (name, args) - returns service instance by name if service does not exists create with arguments args find(callback) - returns all services where callback returns true findFirst (callback) - return first service on callback returns true resolveService(service, args) - resolves service service with arguments args and returns instance resolveArg (arg) - returns service instance with name arg or arg services - list of services names

Example

import createService, { DI } from 'nodic';

const di = new DI();
const serviceDate = createService('date', { factory: () => new Date(), tags: ['date'] });
const serviceCurDate = createService('currentDate', { factory: () => new Date(), shared: false, tags: ['date'] });

di.register(serviceDate);
di.register(serviceCurDate);

console.log(di.get('date') === di.get('date')); // true
console.log(di.get('currentDate') === di.get('currentDate')); // false
