From 9ad0d9be93817dc73a6bdf2a5cca17a43e13b758 Mon Sep 17 00:00:00 2001 From: Tudor Stanciu Date: Mon, 13 Oct 2025 01:14:37 +0300 Subject: [PATCH] feat: update version to 1.2.0 and refactor backend structure - Changed main entry point from `index.js` to `server.js` in package.json. - Created a new `app.ts` file to encapsulate Express app configuration. - Removed old `index.ts` file and moved server logic to `server.ts`. - Updated nodemon configurations to point to the new `server.ts`. - Added new middleware for API key authentication with public endpoint support. - Modified validators to accept any string for IPs, allowing handlers to determine validity. - Added integration tests for batch lookup and health endpoints. - Implemented unit tests for error handling and validation middleware. - Updated `tsup` and `vitest` configurations to reflect new entry points and testing setup. --- Dockerfile | 2 +- README.md | 77 +- content/Overview.json | 29 +- content/ReleaseNotes.json | 139 +++ package-lock.json | 969 ++++++++++++++++++- package.json | 4 +- src/backend/app.ts | 103 ++ src/backend/index.ts | 164 ---- src/backend/middleware/auth.ts | 4 +- src/backend/middleware/validators.ts | 2 +- src/backend/nodemon-debug.json | 2 +- src/backend/nodemon.json | 2 +- src/backend/package.json | 17 +- src/backend/server.ts | 82 ++ src/backend/tests/integration/batch.test.ts | 125 +++ src/backend/tests/integration/health.test.ts | 56 ++ src/backend/tests/integration/lookup.test.ts | 125 +++ src/backend/tests/setup.ts | 33 + src/backend/tests/unit/errorHandler.test.ts | 139 +++ src/backend/tests/unit/validators.test.ts | 136 +++ src/backend/tsup.config.ts | 2 +- src/backend/vitest.config.ts | 30 + 22 files changed, 2059 insertions(+), 183 deletions(-) create mode 100644 src/backend/app.ts delete mode 100644 src/backend/index.ts create mode 100644 src/backend/server.ts create mode 100644 src/backend/tests/integration/batch.test.ts create mode 100644 src/backend/tests/integration/health.test.ts create mode 100644 src/backend/tests/integration/lookup.test.ts create mode 100644 src/backend/tests/setup.ts create mode 100644 src/backend/tests/unit/errorHandler.test.ts create mode 100644 src/backend/tests/unit/validators.test.ts create mode 100644 src/backend/vitest.config.ts diff --git a/Dockerfile b/Dockerfile index ebade20..335b40c 100644 --- a/Dockerfile +++ b/Dockerfile @@ -99,4 +99,4 @@ HEALTHCHECK --interval=30s --timeout=3s --start-period=10s --retries=3 \ # Start the application ENTRYPOINT ["dumb-init", "--"] -CMD ["node", "dist/backend/index.js"] +CMD ["node", "dist/backend/server.js"] diff --git a/README.md b/README.md index b3ef4fb..3024c9f 100644 --- a/README.md +++ b/README.md @@ -332,11 +332,20 @@ The API returns appropriate HTTP status codes: Bitip/ ├── src/ │ ├── backend/ # Express.js API server -│ │ ├── routes/ # API route handlers +│ │ ├── handlers/ # Route handlers (separated by concern) +│ │ ├── middleware/ # Express middleware (auth, rate limiting, validators, errorHandler) +│ │ ├── routes/ # API routes (declarative, minimal) │ │ ├── services/ # Business logic (GeoIP, config, logger) -│ │ ├── middleware/ # Express middleware (auth, rate limiting) +│ │ ├── tests/ # Test suite (integration + unit tests) +│ │ │ ├── integration/ # API endpoint tests (25 tests) +│ │ │ ├── unit/ # Middleware unit tests (18 tests) +│ │ │ └── setup.ts # Test configuration and helpers │ │ ├── types/ # TypeScript type definitions -│ │ ├── index.ts # Main server entry point +│ │ ├── utils/ # Utilities (errors, paths) +│ │ ├── app.ts # Express app factory (without server) +│ │ ├── server.ts # Server startup and lifecycle +│ │ ├── index.ts # Entry point (backward compatible) +│ │ ├── vitest.config.ts # Test configuration │ │ ├── nodemon.json # Nodemon configuration │ │ ├── tsconfig.json # TypeScript configuration │ │ └── package.json # Backend dependencies @@ -377,6 +386,13 @@ npm run build:frontend # Build frontend only # Production npm start # Start production backend server (after build) +# Testing +cd src/backend +npm test # Run all tests once +npm run test:watch # Run tests in watch mode +npm run test:ui # Open Vitest UI dashboard +npm run test:coverage # Run tests with coverage report + # Code Quality npm run lint # Lint both frontend and backend npm run lint:fix # Fix linting issues @@ -415,6 +431,14 @@ npm run install:all # Install all dependencies (root + backend + frontend) -
