From a73274bd7b0da4c4f38a58a419f36ae15f5820b8 Mon Sep 17 00:00:00 2001 From: flourishbar Date: Tue, 30 Jun 2026 06:42:48 +0100 Subject: [PATCH] feat(ci): [BE-116] Add OpenAPI generation check and artifact upload - Add BackEnd/scripts/generate-openapi.ts: headless NestJS bootstrap that exports the full Swagger/OpenAPI JSON document without starting an HTTP server or requiring real external services (DB, Redis, etc.). Environment variable stubs are set inside the script and mirrored explicitly in CI so the build is fully reproducible. - Add 'openapi:generate' npm script to BackEnd/package.json (via ts-node + tsconfig-paths so path aliases resolve correctly at script runtime). - Update .github/workflows/backend-ci.yml: * New 'openapi-check' job runs after dependency install: 1. Calls npm run openapi:generate to produce dist/openapi/openapi.json 2. Validates the spec (JSON syntax, 'openapi' field present, at least one path) using a pure Python3 inline check (no extra deps). 3. Uploads the spec as a named artifact openapi-spec- with a 30-day retention, so reviewers can download it from any PR run. * 'backend-ci-gate' now depends on both build-and-lint AND openapi-check, failing the gate if either job does not succeed. * CI summary table extended with the new OpenAPI Check row.
