Necessary files in Next.js build

Question

I wrote a Next.js app and I'm close to deploying. I would like to know what are the strictly necessary files to copy on the server to deploy while keeping it SSR (not statically generated with next export):

• just the .next/ folder?
• node modules as well?
• any source code?

Answer 1

Copy .next folder with package.json && npm install --production should install only the dependencies of your app.

Keep the folder structure.

Side note, it is bad practice to copy node_modules between environments because there are some packages that are os specific.
