Add a --watch option to the Next CLI

[SirFrey]

Goals

1. Using Turbopack (Context in background)
2. Avoid using third packages or complex configuration to achieve this
3. Track files that Next itself can't track

Non-Goals

I think it is very clear...

Background

I'm actually using a package called next-remote-watch that do the job for .mdx and .json files, the problem is that I can't use Turbopack with it and it is susceptible to break. besides, a native implementation it's gonna be more optimized and ready to use without installing packages and doing complex configuration for it.

Example:
Before:

  "scripts": {
    "dev": "next-remote-watch",
  }

After:

  "scripts": {
    "dev": "next --watch .",
  }

In the last example now you have the option to extend the configuration with the options that Next's CLI offers to you (like --turbo).

Proposal

Hmm, like a standard --watch option, like the one that has node, bun, etc...
