Problem
A forum backend needs clear boundaries for identity, profile data, authored posts, and comments. It also needs to protect write operations, validate incoming data, and return predictable API responses that clients can consume consistently.
Approach
This project implements a Bun and Hono API under an /api base path. It provides registration and sign-in flows, hashes passwords with Bun’s password API, issues JWTs, and applies bearer-token middleware to protected profile and post routes.
The API supports profile retrieval and updates, post creation, paginated post listing with author and comment-count data, comment creation, and post-detail responses with their comments. Hono’s Zod validator checks registration, authentication, post, comment, and profile-update payloads at the route boundary.
Prisma models and migrations define the SQL Server data model for users, optional profiles, posts, and comments. A shared response envelope, not-found handler, and error handler keep returned API shapes and errors consistent.
Outcome
The result is a working backend foundation for a forum product, with the primary user and discussion workflows exposed as HTTP endpoints. It demonstrates authentication, request validation, protected routes, relational data access, and paginated retrieval in a lightweight TypeScript runtime. The repository does not include validated usage or performance metrics, so none are claimed here.
Responsibilities
- Built the Hono route structure, controllers, middleware, and shared API response model.
- Implemented registration, sign-in, JWT issuance and verification, and protected route handling.
- Developed profile, post, and comment endpoints, including paginated post retrieval and comment counts.
- Defined Zod schemas for request validation and Prisma models and migrations for SQL Server persistence.
- Used Bun’s native password hashing and verification APIs for credential handling.
