Parallelizing npm Scripts with Concurrent Execution

In package development, simultaneously executing multiple dependent scripts is often a necessity. To alleviate the sequential execution imposed by npm's default behavior, a powerful solution emerges: concurrently.

Concurrent execution empowers users to run multiple npm scripts side-by-side, ensuring concurrent operation while retaining output visibility. To harness this capability, follow these steps:

1. Install Concurrently:

   • Utilizing your preferred terminal, execute the following command:

     npm i concurrently --save-dev

2. Configure the Development Script:

   • In your package.json, modify the development script as follows:

     "dev": "concurrently --kill-others \"npm run start-watch\" \"npm run wp-server\""

This refined "dev" script leverages concurrently to simultaneously initiate both "start-watch" and "wp-server" scripts. The "--kill-others" flag ensures that if any script fails, all other concurrently running scripts are terminated.
