How to deploy react, next js + express js app to netlify?

Question

I am trying to deploy my app to.netlify which is created by using react, next.js, and express js.

There is no error in.netlify console Despite this, site is not being live.

Here are my package.json scripts.

Here are my variable environments on.netlify.

Here are my build settings to.netlify.

Please can anyone tell me where I am making mistakes?

Answer 1

 npm run build

then drag and drop this build folder but.netlify doesnt support server i think firebase is the best option or herokuu too
