I have tried && in this line also but not works... tsc --watch & nodemon dist/index.js – Upend

You seem to be missing an & character between tsc --watch and nodemon dist/index.js. A single & is not a valid and operator:

"start": "tsc --watch && nodemon dist/index.js",

Update It looks like the issue is on Windows. Commonly this issue is solved by using a library such as concurrently or cross-env to execute commands in a similar way on Windows. After you've installed concurrently:

"start": "concurrently \"tsc --watch\" \"nodemon dist/index.js\"",

Hopefully that helps!

@jimit_jd Okay, update your question to reflect that. Also add to your question what platform you are attempting to execute this command on. – Ingratiate

If i run this project in ubuntu it works fine but not in windows – Upend

@jimit_jd I've updated the question to show one approach using a library for both windows and other platforms. – Ingratiate

Hey Alexander , It works after using concurrently , Thank you so much for your help – Upend

But why it is not running normally in Windows as run in Ubuntu ?? – Upend

It's processed differently on windows just like it wouldn't work if you tried to set an environment variable in the command like ENV=dev or something it wouldn't work on windows. – Ingratiate

Okay I see , and once again Thank you Alexander :) – Upend
