Excore

A minimalist Express framework with dependency injection using JService. Inspired by .Net Core.

JService is a small and powerful pure javascript DI container that favors code over configuration, less oppinionated, no automatic dependency resolution, and with dependency scoping such as Singleton, Scoped and Transient.

Install

npm install excore

Sample Usage

Entry file server.js

import core from 'excore'
import { configureServices, configureApplication } from './startup'

// Create app
const app = core()

// Configure services and application
app.configure(
  configureServices,
  configureApplication
).start()

Startup file for adding and configuring services. startup.js

import { Authentication } from 'excore'
import { Strategy as LocalStrategy } from 'passport-local'
// more imports

// Import services
import Database from './services/database'
import User from './services/user'
// more services

// This is where we add all our services to the container
export function configureServices(services) {

  services.singleton(Database)
  services.transient(User)

  // Add more services
  // services.scoped(Foo)

  // Can also configure built-in/added services
  services.configure(Authentication, () => {
    return auth => {
      auth.use(new LocalStrategy())
    }
  })

}

// This is where we configure our Express
export function configureApplication(app) {

  // Same old middleware utility
  app.use(helmet())
  app.use(bodyParser.json())

  /**
   * Some of built-in Excore middlewares
   */
  app.useAuthentication()
  app.useControllers()

}

Controller

import { api, post, authorize } from 'excore/controller'

@authorize()
@api('user') 
class User {

  // POST /api/user/create
  @post('create') 
  create(req, res) {
    res.jsonSuccess({ world: 'post' })
  }

}

export default User
