I'm trying to Oauth with react native. There aren't any libraries that work for free with Android, iOS, and Web, however Oauth2 is a pretty standard procedure. Seems like there should be a way to make a couple Http requests, configure some redirects, and receive an auth token but I'm having a hard time finding documentation for the procedure for Google.
Here's an example that shows the full OAuth2 procedure in Rust.
I've got the process to work on web using expo-auth-session but it's deprecated and losing support and instead of paying for a solution, I'd rather just implement it myself using some react native primitives.
Does Google have a documented way of authing with Http requests? If not, is there a security reason for why it can't be provided?
Here is the google docs for doing this - https://developers.google.com/identity/protocols/oauth2
