Introduction

Bootstrap and package your project with Angular ^10 , Electron ^10 and TypeOrm ^0.2.28 (Typescript + SASS + Hot Reload) for creating Desktop applications.

Currently runs with:

• Angular v10.0.14
• Electron v10.1.2
• TypOrm v0.2.28
• Electron Builder v22.8.0

/!\ Only Use these repository if you want to use TypeOrm in your application Other wise use angular-electron

/!\ Hot reload only pertains to the renderer process. The main electron process is not able to be hot reloaded, only restarted.

/!\ Angular 10.x CLI needs Node 10.13 or later to work correctly.

Getting Started

Clone this repository locally :

git clone https://github.com/arslanmughal99/angular-electron-typeorm.git

Install dependencies with npm :

npm install

There is an issue with yarn and node_modules when the application is built by the packager. Please use npm as dependencies manager.

If you want to generate Angular components with Angular-cli , you MUST install @angular/cli in npm global context. Please follow Angular-cli documentation if you had installed a previous version of angular-cli.

npm install -g @angular/cli

TypeOrm Connection Options

Before starting make sure to provide TypeOrm connection options in src/app/typeorm.connection.ts

also make sure to first install correct drivers for your database and then require them in angular.webpack.js checkout angular.webpack.js file in the root of the project.

npm install --save pg # if you are using postgres

angular.webpack.js

module.exports = (config, options) => {
  config.target = 'electron-renderer';
  config.externals = {
    typeorm: "require('typeorm')",
    // require drivers like below line for you database here e.g: sqlite, sqljs etc ...
    // example:
    pg: "require('pg')",
  };

  config.resolve = {
    alias: {
      // Also make sure to resolve path for your drivers like below
      // example:
      pg: path.resolve(__dirname, "../node_modules/typeorm/pg"),
      typeorm: path.resolve(__dirname, "../node_modules/typeorm/typeorm-model-shim"),
    }
  };

return config;
}

TypeOrm Entities

import all of your entities in src/app/root.entities.ts  and add to exports default []

import { User } from "./user/user.entity";

export default [
   User,
];

To build for development

• in a terminal window -> npm start

Voila! You can use your Angular + Electron + TypeOrm app in a local development environment with hot reload !

The application code is managed by main.ts. In this sample, the app runs with a simple Angular App (http://localhost:4200) and an Electron window. The Angular component contains an example of Electron and NodeJS native lib import. You can disable "Developer Tools" by commenting win.webContents.openDevTools(); in main.ts.

Use Electron / NodeJS / 3rd party libraries

As see in previous chapter, this sample project runs on both mode (web and electron). To make this happens, you have to import your dependencies the right way. Please check providers/electron.service.ts to watch how conditional import of libraries has to be done when using electron / NodeJS / 3rd party librairies in renderer context (ie. Angular).

Browser mode

Maybe you only want to execute the application in the browser with hot reload ? Just run npm run ng:serve:web.

Included Commands

Command	Description
npm run ng:serve	Execute the app in the browser
npm run build	Build the app. Your built files are in the /dist folder.
npm run build:prod	Build the app with Angular aot. Your built files are in the /dist folder.
npm run electron:local	Builds your application and start electron
npm run electron:build	Builds your application and creates an app consumable based on your operating system

Your application is optimised. Only /dist folder and node dependencies are included in the executable.

You want to use a specific lib (like rxjs) in electron main thread ?

YES! You can do it! Just by importing your library in npm dependencies section (not devDependencies) with npm install --save. It will be loaded by electron during build phase and added to your final package. Then use your library by importing it in main.ts file. Quite simple, isn't it ?

E2E Testing

E2E Test scripts can be found in e2e folder.

Command	Description
npm run e2e	Execute end to end tests

Note: To make it work behind a proxy, you can add this proxy exception in your terminal
export {no_proxy,NO_PROXY}="127.0.0.1,localhost"

This angular-electron-typeorm template repository is build on top of angular-electron so make sure to check that out too . Thanks !
