Strong Typing and Struct Binding -We utilize Gin's `ShouldBindJSON` alongside struct tags to strictly map and validate incoming requests before processing them.

Security Practices -- **Password Hashing:** Passwords are never stored or logged in plain text. We utilize the industry-standard `golang.org/x/crypto/bcrypt` to hash and salt passwords with an appropriate computational cost. -- **JWT Hardening:** The JWT middleware strictly forces the `jwt.WithValidMethods([]string{"HS256"})` and `jwt.WithExpirationRequired()` validators to prevent token tampering or downgrade attacks. -- **Data Isolation:** All protected routes fetch the user ID strictly from the verified JWT token (`c.MustGet("userID")`) injected by the middleware. We never trust `user_id` passed in the HTTP body, effectively preventing lateral data access (IDOR). -- **Graceful Error Recovery:** A global error recovery middleware traps unhandled panics, logs them securely on the server-side, and returns a generic `500 Internal Server Error` to the client, preventing stack trace exposure. - -## 6. Resource Management -- **Database Iterator Safety:** When iterating through `rows.Next()`, we explicitly check `rows.Err()` afterward. This catches scenarios where the iteration abruptly halted due to mid-network disconnects or corruption. -- **Background Cleanup:** Dead data (expired logout tokens) is swept away gracefully by an isolated Go routine initialized at startup `go func() { ... }()`, preventing table bloat over time. diff --git a/docs/backend_schema.md b/docs/backend_schema.md deleted file mode 100644 index 4717985..0000000 --- a/docs/backend_schema.md +++ /dev/null @@ -1,113 +0,0 @@ -# Capuchin Backend Database Schema - -This document outlines the data structures, tables, and relational constraints defined within the backend's PostgreSQL database.

A missed column, wrong type, or forgotten index is easy to introduce and hard to catch before it hits production. - -At that point we will layer in [Atlas](https://atlasgo.io) alongside Goose: - -- Atlas inspects the actual database state and compares it against a desired schema definition. It computes the exact diff and generates the migration SQL automatically. -- Goose continues to own migration execution and versioning. Atlas only generates the files; Goose runs them. -- This separation of concerns is intentional: Atlas handles the "what changed" problem, Goose handles the "apply in order" problem. - -**Genuine reasons to adopt Atlas later:** - -1. **Diff-based generation eliminates human error.** When you have 20+ tables and need to add a nullable column with a default, rename a constraint, or add a partial index, writing that SQL by hand is risky. Atlas generates it correctly from a schema diff every time. -2. **Schema drift detection.** Atlas can compare your migration history against the live database and flag if someone applied a manual hotfix directly to the DB — a common source of production incidents. -3. **Declarative schema as source of truth.** You define what the schema *should* look like, not the steps to get there. This is easier to reason about as the schema grows. -4. **CI integration.** Atlas can lint migrations in CI, catching destructive operations (e.g., dropping a column with data) before they reach production. - -**Why not Atlas alone (without Goose):** -Atlas can run migrations itself, but its execution model is less battle-tested in embedded Go startup scenarios compared to Goose. Goose's `embed.FS` integration and programmatic API are more mature for our use case. The combo gives us the best of both: Atlas for generation, Goose for execution. - ---- diff --git a/docs/readme.md b/docs/readme.md index 92bc19d..692379c 100644 --- a/docs/readme.md +++ b/docs/readme.md @@ -1,162 +1,104 @@ -## 📜 Capuchin: A basic Todo app -A basic full-stack todo list application with a Go (Golang) REST API backend and a React frontend with a professional-grade storage architecture. +## 📜 Capuchin: A robust Todo application +A feature-rich full-stack todo list application with a Go (Golang) REST API backend and a React/Vite frontend using a professional-grade decoupled architecture. ## 🚀 Features Implemented -* **Backend (Go + Gin):** RESTful API with distinct layers (Handlers, Services, DB) and robust error handling. -* **Authentication:** Secure Signup, Login, and Logout using JWT tokens. -* **Database (PostgreSQL):** Relational persistence using `database/sql` with schema migrations managed by Goose v3 on startup. -* **Frontend (React + Vite):** Modern reactive UI with Hooks (useState, useEffect). -* **Styling (Tailwind CSS):** Dark-mode interface with optimistic UI. -* **Architecture:** Clean architecture enforcing separation of concerns in 'internal'. -* **Containerization:** Docker & Docker Compose for Dev/Prod. +* **Backend (Go + Gin):** RESTful API with distinct layers (`handlers`, `services`, `database`, `middleware`) and robust error handling. +* **Authentication:** Secure Signup, Login, and Logout using short-lived JWT tokens with a database-backed token blacklisting mechanism. +* **Database (PostgreSQL):** Relational persistence mapped implicitly to user context to enforce cross-tenant data isolation. +* **Frontend (React + Vite):** Modern reactive UI with custom asynchronous Hooks (`useTodos`, `useAuth`) abstracting away native `fetch` requests. +* **Offline-friendly mode:** Supports an unauthenticated Guest mode backed tightly by `localStorage`. +* **Containerization:** Clean Docker Compose multi-stage orchestrations covering both isolated local development profiles and production scratch-image deployment. ## 📂 Project Structure -``` +```text capuchin/ ├── backend/ │ ├── cmd/ -│ │ └── server/ -│ │ └── main.go # Entry point +│ │ ├── server/ # Entry point for the REST server +│ │ ├── migrate/ # Standalone binary runner for schema definitions +│ │ └── seed/ # Dev DB seed runner │ ├── internal/ -│ │ ├── config/ # Environment & Config setup -│ │ ├── database/ # PostgreSQL connection & init -│ │ ├── handlers/ # HTTP Route handlers -│ │ ├── middleware/ # Auth & Error middleware -│ │ ├── models/ # Data structures -│ │ ├── routes/ # API route definitions -│ │ └── services/ # Core business logic -│ ├── Dockerfile # Backend Container -│ ├── air.toml # Hot Reload Config -│ ├── go.mod # Dependencies -│ └── go.sum +│ │ ├── config/ # Environment & Config map parsing +│ │ ├── database/ # PostgreSQL driver configuration & pooling limits +│ │ ├── handlers/ # HTTP Route logic & payload validation +│ │ ├── middleware/ # Identity resolution & security guards +│ │ ├── models/ # Data structures +│ │ ├── routes/ # Mux mappings setup +│ │ └── services/ # Identity and persistence core logic workflows +│ ├── Dockerfile # Multi-stage Backend Container +│ ├── air.toml # Hot Reload configs +│ ├── go.mod # Go Dependencies +│ └── test.sh # Integration / E2E endpoint bash test harness ├── frontend/ │ ├── src/ +│ │ ├── components/ # Presentational layout components +│ │ ├── hooks/ # Primary React state workflows (`useAuth`, `useTodos`) +│ │ ├── lib/ # Core native-fetch wrapper API logic +│ │ ├── pages/ # Page-level route views +│ │ ├── types/ # TypeScript definitions │ │ ├── App.tsx -│ │ ├── App.css │ │ └── main.tsx -│ ├── Dockerfile # Frontend Container -│ ├── vite.config.ts # Build Config +│ ├── Dockerfile # Nginx + React Multi-stage Frontend Container +│ ├── vite.config.ts # Vite bundling settings │ └── package.json -├── compose.yml # Prod Orchestration -├── compose-dev.yml # Dev Mode Overrides -└── Makefile # Command shortcuts -└── package.json -
