Electron Router DOM

? A react-router-dom adapter for Electron apps

If you’ve already tried using react-router-dom with Electron, had difficulties getting it to work both in development and in production and in different windows, this library is for you!

Features

? Ready for Development and Production environments
? Works on Multiple windows
? Isolated routes by window id

Installation

In your terminal, run:

yarn add electron-router-dom

# OR

npm i electron-router-dom

Router DOM is a peer dependency, if you haven’t installed it yet or your package manager won’t handle it automatically for you, so run:

yarn add react-router-dom

# OR

npm i react-router-dom

Usage

The main thing to keep in mind is: you must use the same window id in the Electron Main Process used in createFileRoute and createURLRoute functions and in the Electron Renderer Process in the <Router> component prop names.

Electron Main Process

import {
  app,
  BrowserWindow,
  BrowserWindowConstructorOptions as WindowOptions,
} from 'electron'

import { createFileRoute, createURLRoute } from 'electron-router-dom'
import { join } from 'path'

function createWindow(id: string, options: WindowOptions = {}) {
  const window = new BrowserWindow({
    width: 700,
    height: 473,
    ...options,
  })

  const devServerURL = createURLRoute(process.env['ELECTRON_RENDERER_URL']!, id)

  const fileRoute = createFileRoute(
    join(__dirname, '../renderer/index.html'),
    id
  )

  process.env.NODE_ENV === 'development'
    ? window.loadURL(devServerURL)
    : window.loadFile(...fileRoute)

  return window
}

app.whenReady().then(() => {
  createWindow('main', {
    webPreferences: {
      preload: join(__dirname, '../preload/index.js'),
    },
  })

  createWindow('about', {
    width: 450,
    height: 350,
    show: false,
  })
})

Electron Renderer Process

Create a routes.tsx file:

import { Router, Route } from 'electron-router-dom'

import { MainScreen, AboutScreen, SearchScreen } from './screens'

export function AppRoutes() {
  return (
    <Router
      main={
        <>
          <Route path="/" element={<MainScreen />} />
          <Route path="/search" element={<SearchScreen />} />
        </>
      }
      about={<Route path="/" element={<AboutScreen />} />}
    />
  )
}

Then, import the AppRoutes in your index.tsx:

import ReactDom from 'react-dom/client'
import React from 'react'

import { AppRoutes } from './routes'

ReactDom
  .createRoot(document.querySelector('app') as HTMLElement)
  .render(
    <React.StrictMode>
      <AppRoutes />
    </React.StrictMode>
  )

A simple example of a MainScreen component:

import { useNavigate } from 'react-router-dom'

// The "App" comes from the context bridge in preload/index.ts
const { App } = window

export function MainScreen() {
  const navigate = useNavigate()

  return (
    <main>
      <button onClick={() => navigate('/search')}>Go to Search screen</button>

      <button onClick={App.OpenAboutWindow}>Open About window</button>
    </main>
  )
}

API

Electron Main Process

createFileRoute

Creates the route for Electron Window loadFile method for production mode with the given window ID.

Params:

path: string
id: string
options?: Electron.LoadFileOptions

Return:

Array: [string, Electron.LoadFileOptions]

Example:

mainWindow.loadFile(
  ...createFileRoute(
    join(__dirname, '../renderer/index.html'),
    'main'
  )
)

createURLRoute

Creates the URL route for Electron Window loadURL method for development mode for the given window ID.

Params:

route: string
id: string

Return: String

Example:

mainWindow.loadURL(
  createURLRoute(
    'http://localhost:3333',
    'main'
  )
)

Electron Renderer Process

Router

The prop names should be the window ids used in main process passsing a Route component to be rendered when route/window matches

Props: [windowID: string]: JSX.Element

Example:

<Router
  main={<Route path="/" element={<MainScreen />} />}
  about={<Route path="/" element={<AboutScreen />} />}
  settings={<Route path="/" element={<SettingsScreen />} />}
/>

Multiple Routes in the same window

<Router
  main={
    <>
      <Route path="/" element={<MainScreen />} />
      <Route path="/search" element={<SearchScreen />} />
    </>
  }
/>

Route

It’s the react-router-dom <Route /> component, same props, same usage. ?
