How Can I Run Multiple Npm Scripts in Parallel?

When working with JavaScript projects, it is common to have multiple npm scripts that need to be executed. However, running them one after the other can be time-consuming and inefficient. In this blog post, we will explore how to run multiple npm scripts in parallel, saving you time and improving your workflow.

There are a few different approaches to achieve parallel execution of npm scripts. Let’s take a look at some of them:

1. Using the npm-run-all package

The npm-run-all package provides a simple and convenient way to run multiple npm scripts in parallel. To use it, you need to install it as a development dependency:

npm install --save-dev npm-run-all

Once installed, you can update your package.json file to define a new script that runs multiple scripts in parallel. Here’s an example:

"scripts": {
  "start": "npm-run-all script1 script2 script3"
}

In the above example, the “start” script will run “script1”, “script2”, and “script3” in parallel. You can replace these with the actual names of your scripts.

2. Using the concurrently package

The concurrently package is another popular option for running npm scripts in parallel. To use it, you need to install it as a development dependency:

npm install --save-dev concurrently

Once installed, you can update your package.json file to define a new script that uses the “concurrently” command. Here’s an example:

<

pre>"scripts": {
"start": "concurrently "npm run script1"" ""npm run script2"" ""npm run script3""""
