While writing my last article I was running my blog on port 3000, and since I test all of my articles with actually building it myself, I came across needing to run the projects on another port.

Changing the port

I've decided I would start running my blog on port 3002. It's as simple as opening package.json file and changing the dev script:

"scripts": {
- "dev": "next",
+ "dev": "next -p 3002",
  "build": "next build",
  "start": "next start"
}

Now when you run npm run dev it'll start your project on port 3002, or whatever number you've chosen.

That's it.
