We initially wrote about this some time ago, to want to have a standard way to support redirects / Single Page App (SPA) mode on the standard IPFS HTTP Gateway.
There is now a tracking issue in the ipfs specs repo: Manifest for unixfs loaded via HTTP Gateway · Issue #257 · ipfs/specs · GitHub
Manifest Review
Netlify
Netlify supports a TOML system for specifying various settings:
As well as a plain text redirects file:
Cloudflare Pages
CF Pages uses a plain text redirects file
https://developers.cloudflare.com/pages/platform/redirects
As well as a plain text _headers file:
https://developers.cloudflare.com/pages/platform/headers
The idea is that we use a manifest file over time for a number of settings. This should be one of YAML or TOML likely – with a slight leaning towards TOML. There will be some bike shedding around this for sure.
I think we should also support a plain text redirects file to start, for maximum compatibility with apps on Netlify.
Supporting definition of a path to a 404 page is the other existing feature that could be defined in the manifest to start.
