2024 Roadmaps - I'm back!

Support

Next.js vs Nextron

next	nextron
v14.x	v9.x
v12.x / v13.x	v8.x
v11.x	v7.x
v10.x	v6.x
v9.x	v5.x
v8.x	v4.x
v7.x	v2.x / v3.x
v6.x	v1.x

Package Manager

npm, yarn and pnpm are supported.

My Belief for Nextron

• Show a way of developing desktop apps with only web knowledge
• Easy to use
• Be transparent and open to OSS developers

Usage

Create Application with Template

We can use examples/* as a template.

To create the examples/with-tailwindcss, run the command below:

# with npx
$ npx create-nextron-app MY_APP --example with-tailwindcss

# with yarn
$ yarn create nextron-app MY_APP --example with-tailwindcss

# with pnpm
$ pnpm dlx create-nextron-app MY_APP --example with-tailwindcss

Run Electron with Development Mode

Run npm run dev, and nextron automatically launches an electron app.

{
  "scripts": {
    "dev": "nextron"
  }
}

Production Build

Run npm run build, and nextron outputs packaged bundles under the dist folder.

{
  "scripts": {
    "build": "nextron build"
  }
}

module.exports = {
  // we need to export static files so as Electron can handle them
  output: 'export',

  distDir:
    process.env.NODE_ENV === 'production'
      ? // we want to change `distDir` to "../app" so as nextron can build the app in production mode!
        '../app'
      : // default `distDir` value
        '.next',

  // e.g. home.html => home/index.html

  // we need to disable image optimization, because it is not compatible with `{ output: 'export' }`

  // webpack config for next.js

}

nextron or nextron dev Options

--renderer-port (default: 8888)

It specifies next dev server port:

{
  "scripts": {
    "dev": "nextron --renderer-port 7777"
  }
}

--run-only (default: undefined)

It suppresses hot reloading of the main process:

{
  "scripts": {
    "dev": "nextron --run-only"
  }
}

--startup-delay (default: 0)

It waits until renderer process is ready (milliseconds):

{
  "scripts": {
    "dev": "nextron --startup-delay 3000"
  }
}

--electron-options (default: undefined)

We can pass electron args via --electron-options:

{
  "scripts": {
    "dev": "nextron --electron-options=\"--no-sandbox\""
  }
}

nextron build Options

NOTE:

• To build macOS binary, your host machine must be macOS!
• Please consider to use electron-builder.yml instead of these CLI options.
  • Command Line Interface (CLI) - electron-builder
  • Common Configuration - electron-builder

To build Windows 32 bit version, run npm run build:win32 like below:

{
  "scripts": {
    "build": "nextron build",
    "build:mac": "nextron build --mac",
    "build:mac:universal": "nextron build --mac --universal",
    "build:linux": "nextron build --linux",
    "build:win32": "nextron build --win --ia32",
    "build:win64": "nextron build --win --x64"
  }
}

--config (default: ./electron-builder.yml)

{
  "scripts": {
    "build": "nextron build --config ./configs/electron-builder.prod.yml"
  }
}

--publish (default: undefined)

Note

Highly recommend to use electron-builder.yml:

https://www.electron.build/configuration/publish

--no-pack (default: undefined)

This option skips packaging by electron-builder:

{
  "scripts": {
    "build": "nextron build --no-pack"
  }
}

Build Configuration: electron-builder.yml

Edit electron-builder.yml for custom build configurations:

appId: com.example.nextron
productName: My Nextron App
copyright: Copyright © 2020 Yoshihide Shiono
directories:
  output: dist
  buildResources: resources
files:
  - from: .
    filter:
      - package.json
      - app
publish: null # see https://www.electron.build/configuration/publish

For more information, please check out electron-builder official configuration documents.

Custom Config: nextron.config.js

module.exports = {
  // specify an alternate main src directory, defaults to 'main'
  mainSrcDir: 'main',
  // specify an alternate renderer src directory, defaults to 'renderer'
  rendererSrcDir: 'renderer',

  // main process' webpack config
  webpack: (config, env) => {
    // do some stuff here
    return config
  },
}

Custom Babel Config for Main Process

We can extends the default babel config of main process by putting .babelrc in our project root like this:

.babelrc:

{
  "presets": ["nextron/babel"]
}

examples/basic-launch-app-from-url

This example shows how to open your app from browser URL.

Note: this example works only production build!

# with npx
$ npx create-nextron-app my-app --example basic-launch-app-from-url

# with yarn
$ yarn create nextron-app my-app --example basic-launch-app-from-url

# with pnpm
$ pnpm dlx create-nextron-app my-app --example basic-launch-app-from-url

# --------------------------------------------------------------

# Production build
$ yarn build (or `npm run build` or `pnpm run build`)

After production build, open your-custom-protocol://open?token=jwt-value in your browser, then the app will be shown like a magic!

If you want to change schema URL, please edit electron-builder.yml#protocols:

protocols:
  name: Your App Name
  schemes: [your-custom-protocol-edited]

Then, you can see the app from URL: your-custom-protocol-edited://any-uri-here?data=include-any-data.
