Auto-detect Next.js framework on `netlify build`

[akd-io]

Which problem is this feature request solving?

Netflify's CLI is a bit behind in UX compared to Vercel's CLI.

I'm building Create Next Stack, and I'm having trouble getting the Netlify CLI to auto-detch that my repository is using Next.js when running netlify deploy. If this is correct, it doesn't seem to be possible to deploy a Next.js from the CLI without setting up configuration first. And maybe using the Next.js plugin?

At the moment running netlify deploy in a new Next.js project looks like below.

$ netlify deploy
This folder isn't linked to a site yet
? What would you like to do? +  Create & configure a new site
? Team: my-team
? Site name (leave blank for a random name; you can change it later): my-site

If everything looks good on your draft URL, deploy it to your main site URL with the --prod flag.
netlify deploy --prod

When following the link to the build logs, you are met with a broken build, as the CLI didn't detect a Next.js project, and all steps were skipped:

Describe the solution you'd like

I'd like Netflify's CLI to auto-detect Next.js like Vercel's CLI does as follows:

$ vercel
Vercel CLI 30.2.2
? Set up and deploy “~/workspace/create-next-stack-tests/a6
7e4390-1fce-4284-b9a6-0268f8006453”? [Y/n] y
? Which scope do you want to deploy to? my-scope
? Link to existing project? [y/N] n
? What’s your project’s name? my-app
? In which directory is your code located? ./
Local settings detected in vercel.json:
Auto-detected Project Settings (Next.js): <-------------- AUTO-DETECTS HERE
- Build Command: next build
- Development Command: next dev --port $PORT
- Install Command: `yarn install`, `pnpm install`, or `npm install`
- Output Directory: Next.js default
? Want to modify these settings? [y/N] n
