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
"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.
