Updated on April 4, 2024

To run multiple npm scripts in parallel, you can use a task runner like concurrently or npm-run-all. These tools allow you to execute multiple commands concurrently, making it easy to run multiple npm scripts simultaneously.

Using concurrently

  1. Install concurrently globally (if not already installed):

     
    npm install -g concurrently

  2. Update your package.json to include scripts that you want to run concurrently:

     
    {
  "scripts": {
    "start": "node server.js",
    "build": "webpack",
    "lint": "eslint src",
    "dev": "concurrently \\"npm run start\\" \\"npm run build\\" \\"npm run lint\\""
  }
}

  3. Run the concurrent npm scripts:

     
    npm run dev

Using npm-run-all

  1. Install npm-run-all globally (if not already installed):

     
    npm install -g npm-run-all

  2. Update your package.json to include scripts that you want to run concurrently:

     
    {
  "scripts": {
    "start": "node server.js",
    "build": "webpack",
    "lint": "eslint src",
    "dev": "npm-run-all --parallel start build lint"
  }
}

  3. Run the concurrent npm scripts:

     
    npm run dev

Both concurrently and npm-run-all provide options for running scripts in parallel or in a specific sequence. Adjust the scripts in your package.json file according to your project's needs.

Choose the tool that best fits your requirements and integrates well with your project.
