simple-container

Zero deps container

Usage

import SimpleContainer from '@skbkontur/SimpleContainer'

const hebrewFactory = ({ httpClient, log }) => ({
  async brew() {
    try {
      await httpClient('/api/brew')
    } catch (ex) {
      log.error(ex)
    }
  }
})

const container = new SimpleContainer()
  .registerFactory('hebrew', hebrewFactory)
  .registerValue('httpClient', fetch.bind(global))
  .registerValue('log', console)

const hebrew = container.resolve('hebrew')

hebrew.brew()

Api

SimpleContainer — class instantiates container

Instance methods

.registerValue(name, value) — registers value in container

.registerClass(name, klass) — registers class in container. When resolves, instance would be created with cradle to constructor

.registerFactory(name, factory) — registers factory function in container. When resolves, function would be called with cradle passed to arguments

.resolve(name) — resolves registered item

Instance properties

.cradle — Proxy, which resolves items on property get. For example:

const hebrew = container.cradle.hebrew
// is the same as
const hebrew = cotainer.resolve('hebrew')
