# Or Yarn
yarn add einf
# Or PNPM
pnpm add einf

Usage

Entry point of your electron application like index.ts:

import { BrowserWindow, app } from 'electron'
import { createEinf } from 'einf'
import { AppController } from './app.controller'

async function bootstrap() {
  const window = new BrowserWindow()
  window.loadURL('https://github.com')

  await createEinf({
    // window to create
    window,
    // controllers will be automatically initialized
    controllers: [AppController],
    // custom items to inject
    injects: [{
      name: 'IS_DEV',
      inject: !app.isPackaged,
    }],
  })
}

bootstrap()

Provide at least one controller to start the application, app.controller.ts:

import type { BrowserWindow } from 'electron'
import { app } from 'electron'
import { Controller, Inject, IpcHandle, IpcSend, Window } from 'einf'
import type { AppService } from './app.service'

@Controller()
export class AppController {
  constructor(
    private appService: AppService,
    @Inject('IS_DEV') private isDev: boolean,
    @Window() private win: BrowserWindow,
  ) {}

  @IpcSend('reply-msg')
  public replyMsg(msg: string) {
    return msg
  }

  @IpcHandle('send-msg')
  public sendMsg(msg: string) {
    console.log(msg)
    return 'Get msg'
  }

  @IpcHandle('exit')
  public exit() {
    app.quit()
  }
}

You can also inject service via @Injectable decorator, app.service.ts:

import { Injectable } from 'einf'

@Injectable()
export class AppService {
  public createMsg(msg: string): string {
    return `"${msg}" is created by app service`
  }
}
