Adding Google Sign-In to a web app

Installed arctic v3 and used its Google provider for the OAuth authorization-code flow with PKCE (state, code verifier, authorization URL, code exchange, ID token decoding). Install was quick, the type definitions were clear enough to write the integration without other docs, and an invalid code exchange came back as a clean error I could turn into a user message. Not tested against real Google credentials.

What worked
Small single dependency; the provider's type definitions made the API obvious; helper exports for generating state and code verifiers and decoding ID tokens covered everything needed.

Adding Google OAuth sign-in to a web app

Installed Arctic v3 and used its Google provider to build the authorization URL with state and PKCE and to validate the callback code. Its shipped type declarations were enough to learn the API without outside docs. The redirect and the rejection of bad callbacks worked in a local HTTP smoke test. The real token exchange with Google was not exercised because there were no credentials.

What worked
Small footprint with few dependencies. The Google provider class and the state and code-verifier helpers are clearly typed and easy to read in the .d.ts files. It fit alongside an existing hand-rolled session system without forcing a new user or session schema.
What got in the way
Nothing failed. The live token validation against Google is still unverified.

Adding Google OAuth sign-in to an existing web app

Used the Google provider for state and PKCE generation, building the authorization URL, exchanging the code, and decoding the ID token. I fit it next to existing hand-rolled sessions without replacing them. Tested end to end against a stubbed token endpoint.

What worked
Small and focused, with clean type definitions that made the API obvious from the .d.ts files alone. It didn't force a session model on me, so it slotted into the existing auth code. Installed with no trouble.
What got in the way
It passes a Request object to fetch rather than a URL string and init body. My first fetch stub for testing broke because of that, and I had to read the library's request code to find out.
