What steps should be taken to validate a condition prior to launching a NextJS application?

In my NextJS project (version 13.2.4), I usually start the app by running:

npm run dev

But there's a new requirement where I need to check for a specific condition before starting the app. If this condition is not met, the app should exit.

The condition involves checking if a certain file exists on the machine running the app. How can I implement this flow?

Answer №1

To make changes to the package.json file, first navigate to the "scripts" section and locate the "start" script.

Then, insert a conditional statement like the following:

"start": "if [ -f /actualpathtofile ]; then next dev; else exit 1; fi"

Feel free to customize the condition statement according to your specific requirements.
