From cb34e0db70401565003e5ceb5e4c5cfa4b439d7c Mon Sep 17 00:00:00 2001 From: Caxton22 Date: Mon, 9 Mar 2026 12:45:26 +0100 Subject: [PATCH] feat: implement credential controller and routes - Add GET /credentials endpoint for user credentials with filtering and pagination - Add GET /credentials/:id endpoint for single credential details - Add GET /credentials/verify/:onChainId for public verification - Implement comprehensive validation using Zod schemas - Add 14 unit tests with full coverage - Update routes index to include credentials endpoints Closes #8 --- PR_DESCRIPTION.md | 95 +++++ src/controllers/credential.controller.ts | 250 ++++++++++++ src/routes/index.ts | 2 + src/routes/v1/credentials.routes.ts | 54 +++ tests/unit/credential.controller.test.ts | 477 +++++++++++++++++++++++ 5 files changed, 878 insertions(+) create mode 100644 PR_DESCRIPTION.md create mode 100644 tests/unit/credential.controller.test.ts diff --git a/PR_DESCRIPTION.md b/PR_DESCRIPTION.md new file mode 100644 index 0000000..db48cbe --- /dev/null +++ b/PR_DESCRIPTION.md @@ -0,0 +1,95 @@ +# Credential Controller & Routes Implementation + +## Overview +Implements credential management endpoints for certificates and achievements as specified in issue #8. + +## Changes Made + +### New Files +- `src/controllers/credential.controller.ts` - Controller with three main endpoints +- `src/routes/v1/credentials.routes.ts` - Route definitions with validation +- `tests/unit/credential.controller.test.ts` - Comprehensive unit tests (14 tests, all passing) + +### Modified Files +- `src/routes/index.ts` - Added credentials routes to API + +## Implemented Endpoints + +### 1.
