How-To Setup Redirects For A Next.js Site On Netlify
To use a `_redirects` file, set one up in the root of your project then change your `build` line in `package.json` to:
"build": "next build && cp _redirects .next/",
That puts the file in the right place at the end of the build process.
which says: "Save a plain text file called `_redirects` without a file extension to the publish directory of your site." but doesn't tell you how to actually do it.
TODO: put in syntax
Note: saw this in the build page of netlify:
A _redirects file is present in the repository but is missing in the publish directory ".next".
That was before I pushed it in with that package.json update.
