Installation

Development Setup

This config works when using nodejs and yarn installed for windows (not through ubuntu in windows).

Install / Update Node and yarn:

https://nodejs.org/en/

https://yarnpkg.com/en/

Install shell launcher:

Add vs code extension shell launcher.

https://github.com/Tyriar/vscode-shell-launcher

Use it by crtl-shft-p 'shell'. Electron apps must be run from cmd.

Clone the repo via git:

git clone --depth=1 https://github.com/chentsulin/electron-react-boilerplate.git your-project-name

And then install dependencies with yarn (from the node.js command prompt).

$ cd your-project-name
$ yarn

Run

Start the app in the dev environment. This starts the renderer process in hot-module-replacement mode and starts a webpack dev server that sends hot updates to the renderer process:

$ yarn dev

Alternatively, you can run the renderer and main processes separately. This way, you can restart one process without waiting for the other. Run these two commands simultaneously in different console tabs:

$ yarn start-renderer-dev
$ yarn start-main-dev

If you don't need autofocus when your files was changed, then run dev with env START_MINIMIZED=true:

$ START_MINIMIZED=true yarn dev

Packaging

To package apps for the local platform:

$ yarn package

To package apps for all platforms:

First, refer to Multi Platform Build for dependencies.

Then,

$ yarn package-all

To package apps with options:

$ yarn package -- --[option]

💡 You can debug your production build with devtools by simply setting the DEBUG_PROD env variable:

DEBUG_PROD=true yarn package

CSS Modules

This boilerplate is configured to use css-modules out of the box.

All .css file extensions will use css-modules unless it has .global.css.

If you need global styles, stylesheets with .global.css will not go through the css-modules loader. e.g. app.global.css

If you want to import global css libraries (like bootstrap), you can just write the following code in .global.css:

@import '~bootstrap/dist/css/bootstrap.css';

SASS support

If you want to use Sass in your app, you only need to import .sass files instead of .css once:

import './app.global.scss';
