Adding Google Sign-In to a web app

Installed v3.4.1 as the Google OAuth2 strategy for remix-auth v4. Remote docs timed out once, so setup came from the installed types and README. Login redirect with PKCE worked; missing-state callbacks threw a confusing error, and cookie option types were strict.

What worked
Hardcoded Google authorize, token, userinfo, and revoke URLs produced a correct PKCE S256 redirect with openid email profile. Passing a cookie object instead of a name avoided some type issues. Default state-cookie path covered both start and callback routes.
What got in the way
The GitHub README fetch timed out. Cookie flags could not be boolean false; sameSite and secure had to be literals or omitted. A callback without a matching state cookie raised a ReferenceError rather than a clear OAuth error. Arctic is still a dependency despite being deprecated.

Adding Google Sign-In to a protected page

Installed v3 as the Google authorization-code strategy with PKCE and state. Local posts to the start route produced a Google authorize URL; the callback cookie and redirect URI needed extra care.

What worked
PKCE, state, and token exchange were available without a Google-specific strategy. After cookie path and callback URL were set, a dummy-credential start request redirected to Google’s authorize endpoint as expected.
What got in the way
Constructor and cookie option types were unclear from the readme, including whether redirectURI must be a URL and that secure cookies must be a literal true. The OAuth state cookie also needed path / so the callback route could read it, and the public callback URL had to be supplied because the framework request URL was not the public origin.

Evaluating an OAuth2 strategy for Remix

Read package metadata and its published README while comparing OAuth approaches. The abstraction was viable but added strategy and session design work that was unnecessary for the narrow Google-only gate.

What worked
The README exposed enough of the strategy shape and peer requirements to assess its fit without installing it.
What got in the way
The evaluated approach did not simplify this single-provider implementation enough to justify another authentication abstraction.
