From 13021c8ecff060542a1bdf21253160703571e6ec Mon Sep 17 00:00:00 2001 From: Naomi Chopra Date: Tue, 11 Nov 2025 17:56:52 -0800 Subject: [PATCH 1/4] feat(api): enhance event handling and authentication in API - Added new authentication plugins for API key and JWT verification. - Implemented event processing logic for signup and purchase events, including referral attribution. - Created routes for handling widget initialization and program retrieval. - Introduced a service for event creation and reward processing. - Enhanced error handling and validation for event submissions. - Updated package dependencies and lock file to reflect new additions. - Added comprehensive tests for event processing and referral logic. --- apps/api/package.json | 10 +- apps/api/src/app.ts | 35 ++- apps/api/src/index.ts | 1 + apps/api/src/plugins/better-auth.ts | 106 ++++++++ apps/api/src/plugins/jwt-auth.ts | 94 +++++++ apps/api/src/routes/v1/events.ts | 215 +++++++++++++++ apps/api/src/routes/v1/programs.ts | 59 +++++ apps/api/src/routes/v1/widget/init.ts | 233 +++++++++++++++++ apps/api/src/services/events.ts | 72 +++++ apps/api/src/services/reward-engine.ts | 234 +++++++++++++++++ apps/api/test/events.test.ts | 245 ++++++++++++++++++ apps/api/test/setup.ts | 31 ++- .../test/unit/referral-attribution.test.ts | 165 ++++++++++++ apps/api/test/unit/reward-calculation.test.ts | 147 +++++++++++ packages/utils/src/plugins/coredb.ts | 12 +- pnpm-lock.yaml | 55 +++- 16 files changed, 1691 insertions(+), 23 deletions(-) create mode 100644 apps/api/src/plugins/better-auth.ts create mode 100644 apps/api/src/plugins/jwt-auth.ts create mode 100644 apps/api/src/routes/v1/events.ts create mode 100644 apps/api/src/routes/v1/programs.ts create mode 100644 apps/api/src/routes/v1/widget/init.ts create mode 100644 apps/api/src/services/events.ts create mode 100644 apps/api/src/services/reward-engine.ts create mode 100644 apps/api/test/events.test.ts create mode 100644 apps/api/test/unit/referral-attribution.test.ts create mode 100644 apps/api/test/unit/reward-calculation.test.ts diff --git a/apps/api/package.json b/apps/api/package.json index bd8e55a..507ac24 100644 --- a/apps/api/package.json +++ b/apps/api/package.json @@ -17,12 +17,20 @@ }, "dependencies": { "@fastify/cors": "^10.0.1", + "@paralleldrive/cuid2": "^2.2.2", "@refref/coredb": "workspace:*", + "@refref/id": "workspace:*", + "@refref/types": "workspace:*", "@refref/utils": "workspace:*", + "@tsndr/cloudflare-worker-jwt": "^3.2.0", + "better-auth": "^1.3.32", + "dotenv": "^17.2.3", "drizzle-orm": "^0.33.0", "fastify": "^5.2.0", "fastify-plugin": "^5.0.1", - "postgres": "^3.4.5" + "jose": "^5.9.6", + "postgres": "^3.4.5", + "zod": "^3.23.8" }, "devDependencies": { "@types/node": "^22.10.2", diff --git a/apps/api/src/app.ts b/apps/api/src/app.ts index 58bac8c..9a0a998 100644 --- a/apps/api/src/app.ts +++ b/apps/api/src/app.ts @@ -1,10 +1,25 @@ import Fastify, { FastifyInstance } from "fastify";

From: Naomi Chopra Date: Tue, 11 Nov 2025 19:51:28 -0800 Subject: [PATCH 4/4] chore(api): remove deprecated event and program fetching routes - Deleted the old events route and program fetching scripts to streamline the API. - This cleanup enhances code maintainability and prepares for the new modular event handling structure. - Ensured that all related functionality is now handled by the updated track routes. --- apps/admin/src/app/api/events/route.ts | 202 ------------- .../app/api/scripts/fetch-program/route.ts | 95 ------- .../src/app/api/scripts/widget/init/route.ts | 266
