Set the Port of the Dev Server in a Next.js Project

To set the port of the dev server in a Next.js project, we can add the -p option to the dev command in package.json.

For instance, we write:

"scripts": { 
  "dev": "next -p 8080" 
},

to set the dev server to serve the project on port 8080.

We can also set the PORT environment variable before we run the dev script.

To do this, we type in:

PORT=8080 npx next dev

into the command to run the dev server on port 8080.
