FAQPage Schema

How do I test Google OAuth 2.0 flows locally without hitting real API quotas?▼

You can emulate Google OAuth 2.0 locally by running `npx emulate --service google`, which handles OAuth flows, ID tokens, and refresh tokens without requiring real Google API access.

What is the best way to mock Gmail, Calendar, and Drive API responses during development?▼

Mocking Gmail, Calendar, and Drive API responses is done by starting the local emulator, which simulates Google API functionalities and provides mock responses for application testing.

Does the Google API emulator support OpenID Connect discovery for local development?▼

Yes, the Google API emulator supports OpenID Connect discovery, allowing you to handle OIDC flows and test ID tokens locally without connecting to live Google authentication servers.

Do I need portless to get HTTPS URLs when emulating Google APIs?▼

Yes, while `npx emulate` starts the Google API emulator, the optional `portless` dependency is required if you need to generate HTTPS URLs for your local development and testing environment.

When should I use a Google API emulator instead of real Google API credentials?▼

Use a Google API emulator during local development and testing to eliminate the need for real Google API calls, preventing accidental quota exhaustion and removing the dependency on live Google API access.
