From c536b65aa708c85ada6b3b32e7f4b4c6d2914ec0 Mon Sep 17 00:00:00 2001 From: Yonatan Gross Date: Wed, 8 Apr 2026 15:03:27 +0300 Subject: [PATCH 1/4] feat(google): add Calendar discovery document endpoint Add GET /discovery/v1/apis/calendar/v3/rest serving a minimal discovery document that describes the Calendar routes this emulator implements: calendarList.list, events.list, events.insert, events.delete, and freebusy.query. This enables google-api-python-client build("calendar", "v3") and similar SDK bootstrapping to work against the emulator without hitting the real Google API. - No auth required (matches real Google behavior) - rootUrl dynamically reflects the server origin - 2 files changed, +117 lines Co-Authored-By: Claude Opus 4.6 (1M context) --- .../google/src/__tests__/google.test.ts | 33 +++++++ .../@emulators/google/src/routes/calendar.ts | 85 ++++++++++++++++++- 2 files changed, 117 insertions(+), 1 deletion(-) diff --git a/packages/@emulators/google/src/__tests__/google.test.ts b/packages/@emulators/google/src/__tests__/google.test.ts index 046d6942..6fd97871 100644 --- a/packages/@emulators/google/src/__tests__/google.test.ts +++ b/packages/@emulators/google/src/__tests__/google.test.ts @@ -1101,4 +1101,37 @@ describe("Google plugin integration", () => { expect(uploadedMediaRes.status).toBe(200);
