Electron Installer for Red Hat

electron-installer-redhat Version Build Status

Create a Red Hat package for your Electron app.

Requirements

This tool requires Node 10 or greater and rpmbuild 4.13 or greater to build the .rpm package.

Note: RPM 4.13.0 or greater is required due to the boolean dependency feature.

On Fedora you can do something like this:

$ sudo dnf install rpm-build

While on Debian/Ubuntu you'll need to do this instead:

$ sudo apt-get install rpm

Installation

For use from command-line:

$ npm install -g electron-installer-redhat

For use in npm scripts or programmatically:

$ npm install --save-dev electron-installer-redhat

Usage

Say your Electron app lives in path/to/app, and has a structure like this:

.
├── LICENSE
├── README.md
├── node_modules
│   ├── electron-packager
│   └── electron
├── package.json
├── resources
│   ├── Icon.png
│   ├── IconTemplate.png
│   └── IconTemplate@2x.png
└── src
    ├── index.js
    ├── main
    │   └── index.js
    └── renderer
        ├── index.html
        └── index.js

You now run electron-packager to build the app for Red Hat:

$ electron-packager . app --platform linux --arch x64 --out dist/

And you end up with something like this in your dist folder:

.
└── dist
    └── app-linux-x64
        ├── LICENSE
        ├── LICENSES.chromium.html
        ├── content_shell.pak
        ├── app
        ├── icudtl.dat
        ├── libgcrypt.so.11
        ├── libnode.so
        ├── locales
        ├── natives_blob.bin
        ├── resources
        ├── snapshot_blob.bin
        └── version

How do you turn that into a Red Hat package that your users can install?

Command-Line

If you want to run electron-installer-redhat straight from the command-line, install the package globally:

$ npm install -g electron-installer-redhat

And point it to your built app:

$ electron-installer-redhat --src dist/app-linux-x64/ --dest dist/installers/ --arch x86_64

You'll end up with the package at dist/installers/app-0.0.1-1.x86_64.rpm.

Scripts

If you want to run electron-installer-redhat through npm, install the package locally:

$ npm install --save-dev electron-installer-redhat

Edit the scripts section of your package.json:

{
  "name": "app",
  "description": "An awesome app!",
  "version": "0.0.1",
  "scripts": {
    "start": "electron .",
    "build": "electron-packager . app --platform linux --arch x64 --out dist/",
    "rpm64": "electron-installer-redhat --src dist/app-linux-x64/ --dest dist/installers/ --arch x86_64"
  },
  "devDependencies": {
    "electron-installer-redhat": "*",
    "electron-packager": "*",
    "electron-prebuilt": "*"
  }
}

And run the script:

$ npm run rpm64

You'll end up with the package at dist/installers/app-0.0.1-1.x86_64.rpm.

Programmatically

Install the package locally:

$ npm install --save-dev electron-installer-redhat

And write something like this:

const installer = require('electron-installer-redhat')

const options = {
  src: 'dist/app-linux-x64/',
  dest: 'dist/installers/',
  arch: 'x86_64'
}

async function main (options) {
  console.log('Creating package (this may take a while)')

  try {
    await installer(options)
    console.log(`Successfully created package at ${options.dest}`)
  } catch (err) {
    console.error(err, err.stack)
    process.exit(1)
  }
}
main(options)

You'll end up with the package at dist/installers/app-0.0.1-1.x86_64.rpm.

Note: As of 2.0.0, the Node-style callback pattern is no longer available. You can use util.callbackify if this is required for your use case.

Options

Even though you can pass most of these options through the command-line interface, it may be easier to create a configuration file:

{
  "dest": "dist/installers/",
  "icon": "resources/Icon.png",
  "categories": [
    "Utility"
  ]
}

And pass that instead with the config option:

$ electron-installer-redhat --src dist/app-linux-x64/ --arch x86_64 --config config.json

Anyways, here's the full list of options:

src

Type: String Default: undefined

Path to the folder that contains your built Electron application.

dest
