First run the following command to check bun is installed or not

bun -v

If you don't have bun installed then run the following command to install bun

curl https://bun.sh/install | bash

Now run the following command to create a next app

bun create next [your-app-name]

It will create a new directory with the name of your app. To start the app run the following command

cd your-app-name
bun dev

We have to update next.js version before we build our next app

bun a next@latest

Here we update to the latest version of next for avoiding any kind of build issue

We can add the following scripts to our package.json file

{
  "scripts": {
    "start": "next start",
    "build": "next build"
  }
}

And we can run the following command to build the production bundle

bun run build

To run the production build you can fire following command

bun start
