Stop the npm start command with a specific error message if the file is not found in the repository

Can the npm start process be stopped or cancelled if a specific file is not found in your codebase?

I am looking to end the process if the file dev-variables.js is missing, preferably displaying a custom error message like "You are missing the dev-variables.js file".

Answer №1

For initializing, use the code snippet prestart found at https://docs.npmjs.com/misc/scripts

"scripts": {
  "prestart": "scripts/check-dev-variables.js"
}

The file path scripts/check-dev-variables.js should be present to avoid any exceptions during execution
