Warning: This is a work in progress

electron-angular-bootstrap-boilerplate

Comprehensive boilerplate application for Electron runtime.

Scope of this project:

  • Provide basic structure of the application so you can much easier grasp what should go where.
  • Give you cross-platform development environment, which works the same way on OSX, Windows and Linux.
  • Generate ready for distribution installers of your app for all three operating systems.
  • Bower, Angular, and Bootstrap are included as a jump start for application development.

#Dependencies

  • Git
  • Nodejs
  • NPM
  • Bower

Quick start

The only development dependency of this project is Node.js. So just make sure you have it installed. Then type few commands known to every Node developer...

git clone https://github.com/szwacz/electron-boilerplate.git
cd electron-boilerplate
npm install
cd app/ && npm install
bower install
cd ..
npm start

... and boom! You have running desktop application on your screen.

Structure of the project

There are two package.json files:

1. For development

Sits on path: electron-boilerplate/package.json. Here you declare dependencies for your development environment and build scripts. This file is not distributed with real application!

Also here you declare the version of Electron runtime you want to use:

"devDependencies": {
  "electron-prebuilt": "^0.34.0"
}

2. For your application

Sits on path: electron-boilerplate/app/package.json. This is real manifest of your application. Declare your app dependencies here.

OMG, but seriously why there are two package.json?

  1. Native npm modules (those written in C, not JavaScript) need to be compiled, and here we have two different compilation targets for them. Those used in application need to be compiled against electron runtime, and all devDependencies need to be compiled against your locally installed node.js. Thanks to having two files this is trivial.
  2. When you package the app for distribution there is no need to add up to size of the app with your devDependencies. Here those are always not included (because reside outside the app directory).

Project's folders

  • app - code of your application goes here.
  • config - place where you can declare environment specific stuff for your app.
  • build - in this folder lands built, runnable application.
  • releases - ready for distribution installers will land here.
  • resources - resources needed for particular operating system.
  • tasks - build and development environment scripts.

Development

Installation

npm install

It will also download Electron runtime, and install dependencies for second package.json file inside app folder.

Starting the app

npm start

Adding npm modules to your app

Remember to add your dependency to app/package.json file, so do:

cd app
npm install name_of_npm_module --save

Native npm modules

Want to use native modules? This objective needs some extra work (rebuilding module for Electron). In this boilerplate it's fully automated, just use special command instead of standard npm install something when want to install native module.

npm run install-native -- name_of_native_module

This script when run first time will add electron-rebuild to your project. After that everything is wired and no further maintenance is necessary.

Working with modules

How about being future proof and using ES6 modules all the time in your app? Thanks to rollup you can do that. It will transpile the imports to proper require() statements, so even though ES6 modules aren't natively supported yet you can start using them today.

You can use it on those kinds of modules:

// Modules authored by you
import { myStuff } from './my_lib/my_stuff';
// Node.js native
import fs from 'fs';
// Electron native
import { app } from 'electron';
// Loaded from npm
import moment from 'moment';

Including files to your project

The build script copies files from app to build directory and the application is started from build. Therefore if you want to use any special file/folder in your app make sure it will be copied via some of glob patterns in tasks/build.js:

var paths = {
    copyFromAppDir: [
        './node_modules/**',
        './vendor/**',
        './**/*.html',
        './**/*.+(jpg|png|svg)'
    ],
}

Unit tests

electron-boilerplate has preconfigured jasmine test runner. To run the tests go with standard:

npm test

You don't have to declare paths to spec files in any particular place. The runner will search through the project for all *.spec.js files and include them automatically.

Making a release

Note: There are various icon and bitmap files in resources directory. Those are used in installers and are intended to be replaced by your own graphics.

To make ready for distribution installer use command:

npm run release

It will start the packaging process for operating system you are running this command on. Ready for distribution file will be outputted to releases directory.

You can create Windows installer only when running on Windows, the same is true for Linux and OSX. So to generate all three installers you need all three operating systems.

Mac only

App signing

The Mac release supports code signing. To sign the .app in the release image, include the certificate ID in the command as so,

npm run release -- --sign A123456789

Windows only

Installer

The installer is built using NSIS. You have to install NSIS version 3.0, and add its folder to PATH in Environment Variables, so it is reachable to scripts in this project. For example, C:\Program Files (x86)\NSIS.

32-bit build on 64-bit Windows

There are still a lot of 32-bit Windows installations in use. If you want to support those systems and have 64-bit OS make sure you've installed 32-bit (instead of 64-bit) Node version. There are versions managers if you feel the need for both architectures on the same machine.
