-# madbase
+# MadBase
 
+**MadBase** is an open-source, high-performance Backend-as-a-Service (BaaS) written in Rust. It serves as a lightweight alternative to Supabase, providing a comprehensive suite of tools for building modern web and mobile applications.
+
+## 🚀 Features
+
+MadBase consolidates the following services into a single, efficient binary:
+
+*   **🔐 Authentication (`/auth/v1`)**
+    *   User Signup & Login (Email/Password).
+    *   JWT-based Session Management.
+    *   Row Level Security (RLS) integration with PostgreSQL.
+*   **💾 Data API (`/rest/v1`)**
+    *   Auto-generated REST API for your Postgres tables.
+    *   CRUD operations (Select, Insert, Update, Delete).
+    *   Filtering, Pagination, and Ordering.
+    *   Stored Procedure (RPC) calls.
+*   **⚡ Realtime (`/realtime/v1`)**
+    *   WebSocket-based event streaming.
+    *   Listen to database changes via Postgres `LISTEN/NOTIFY`.
+*   **📦 Storage (`/storage/v1`)**
+    *   S3-compatible object storage (backed by MinIO).
+    *   File Upload, Download, and Management.
+    *   Integrated RLS permissions for buckets and objects.
+*   **🎛️ Control Plane (`/platform/v1`)**
+    *   Project Management.
+    *   Automatic API Key Generation (`anon` and `service_role`).
+
+## 🛠️ Architecture
+
+MadBase is built as a modular monolith in **Rust**, utilizing the **Axum** web framework for high performance and low latency.
+
+*   **Gateway**: The central entry point that routes requests to appropriate internal modules.
+*   **PostgreSQL**: The primary database for data, auth, and system state.
+*   **MinIO**: S3-compatible object storage.
+
+## 🏁 Getting Started
+
+### Prerequisites
+
+*   **Rust** (latest stable)
+*   **Docker** & **Docker Compose** (for DB and MinIO)
+*   **PostgreSQL Client** (optional, for debugging)
+
+### Installation
+
+1.  **Clone the repository:**
+    ```bash
+    git clone https://github.com/yourusername/madbase.git
+    cd madbase
+    ```
+
+2.  **Start Infrastructure:**
+    Spin up PostgreSQL and MinIO using Docker Compose:
+    ```bash
+    docker-compose up -d
+    ```
+
+3.  **Run Migrations:**
+    Initialize the database schema:
+    ```bash
+    sqlx migrate run
+    ```
+    *(Note: You may need to install sqlx-cli: `cargo install sqlx-cli`)*
+
+4.  **Start the Gateway:**
+    Run the main server:
+    ```bash
+    cargo run -p gateway
+    ```
+    The server will start at `http://0.0.0.0:8000`.
+
+## 📖 Usage Guide
+
+### 1. Create a Project
+Use the Control Plane to initialize a project and get your API keys.
+
+```bash
+curl -X POST http://localhost:8000/platform/v1/projects \
+  -H "Content-Type: application/json" \
+  -d '{"name": "my-awesome-app"}'
+```
+
+**Response:**
+```json
+{
+  "id": "...",
+  "anon_key": "eyJ...",
+  "service_role_key": "eyJ...",
+  ...
+}
+```
+*Save the `anon_key` and `service_role_key`!*
+
+### 2. Authentication
+Sign up a new user:
+
+```bash
+curl -X POST http://localhost:8000/auth/v1/signup \
+  -H "apikey: <ANON_KEY>" \
+  -H "Content-Type: application/json" \
+  -d '{"email": "user@example.com", "password": "securepassword"}'
+```
+
+### 3. Data Operations
+Query a table (e.g., `users`):
+
+```bash
+curl -X GET "http://localhost:8000/rest/v1/users?select=*" \
+  -H "apikey: <ANON_KEY>" \
+  -H "Authorization: Bearer <USER_ACCESS_TOKEN>"
+```
+
+### 4. Realtime
+Connect via WebSocket:
+`ws://localhost:8000/realtime/v1`
+
+### 5. Storage
+Upload a file:
+
+```bash
+curl -X POST http://localhost:8000/storage/v1/object/my-bucket/image.png \
+  -H "apikey: <ANON_KEY>" \
+  -H "Authorization: Bearer <USER_ACCESS_TOKEN>" \
+  -F "file=@./local-image.png"

+# MadBase Development Roadmap
+
+This document outlines the development plan for **MadBase**, a high-performance, resource-efficient, Supabase-compatible API layer written in Rust. The roadmap is derived from the requirements specified in [SPECIFICATIONS.md](./SPECIFICATIONS.md).
+
+## Phase 1: Foundation & Core APIs (MVP)
+**Goal:** Establish the single-binary architecture and deliver functional Auth and Data APIs for a single project context.
+
+### 1.1 Project Scaffolding & Architecture

+### MadBase (Supabase-Compatible Rust API Layer) — Functional & Non-Functional Specification (Updated)
+
+This document specifies **MadBase**, a **Supabase API-compatible** platform implemented primarily in **Rust**, designed to be a drop-in replacement for Supabase’s hosted API surface while supporting **Bring Your Own PostgreSQL**. Primary goals: **low resource usage**, **simplicity**, and **operability** (Docker Compose-first).
+
+## 0. Key Decisions (Chosen for Resource Usage, Simplicity, Operability)
+
+1. **Single Rust “gateway” binary** (one container) exposes Supabase-compatible endpoints:
+   - `/auth/v1/*`, `/rest/v1/*`, `/rpc/v1/*` (or `/rest/v1/rpc/*` depending on compatibility requirements), `/storage/v1/*`, `/realtime/v1/*` (WS), `/functions/v1/*`, `/admin/v1/*`
+2. **Custom “PostgREST-lite” Rust data API** (instead of embedding PostgREST) to reduce runtime overhead and simplify deployment.
+3. **Realtime via PostgreSQL logical replication (pgoutput)** implemented in Rust (no external Debezium/Elixir stack).
+4. **Edge Functions executed as WASM via Wasmtime** (small, fast startup, strong sandbox). (Optionally support “Deno compatibility mode” later if required.)
+5. **Storage API is an S3 proxy** with MinIO default in podman-compose and support for external S3/R2/etc. in production.
+6. **Monitoring: VictoriaMetrics + Loki + Grafana** with Prometheus-format metrics endpoints and JSON stdout logs.
+
+---
+
+## 1. Functional Requirements
+
+### 1.1 Supabase Client Compatibility (Hard Requirement)
+**Goal:** `@supabase/supabase-js` works unchanged. Users only swap the URL.
+
+#### 1.1.1 API Surface Compatibility
+MadBase must mimic Supabase’s public endpoints, including:
+- Path structure (e.g., `/auth/v1`, `/rest/v1`, `/storage/v1`, `/realtime/v1`, `/functions/v1`)
+- Required headers:
+  - `apikey: <anon/service_role key>`
+  - `Authorization: Bearer <jwt>`
+- Status codes and error format consistency (enough to not break supabase-js).
+
+#### 1.1.2 Key Types
+- **Anon key**: public, used by clients for most operations.
+- **Service role key**: privileged, bypasses RLS (admin operations).
+- Key rotation supported per project.
+
+---
+
+### 1.2 Multi-Tenant Projects (Control Plane)
+MadBase is multi-tenant and supports many “projects,” each mapping to:
+- A PostgreSQL connection string (BYO DB/cluster)
+- JWT secret / signing policy
+- Storage backend configuration
+- Function runtime configuration
+- Realtime replication configuration
+
+#### 1.2.1 Project Identification
+Projects are identified via one of:
+- Subdomain-based routing: `https://<project-ref>.<base-domain>`
+- Or header-based routing: `x-project-ref: <ref>` (for internal/admin use)
+
+#### 1.2.2 Project Lifecycle
+- Create project
+- Update project settings (DB URL, keys, storage config)
+- Disable / delete project (with soft-delete option)
+- View usage/health info per project
+
+---
+
+### 1.3 Auth (GoTrue-Compatible-ish)
+MadBase provides auth flows expected by supabase-js.
+
+#### 1.3.1 Supported Flows
+- Email/password signup
+- Email/password login
+- Token refresh (refresh token → new access token)
+- Session retrieval (`/user`)
+- Password reset (email-based) — optional for MVP, but spec’d
+- Email confirmation — optional for MVP, but spec’d
+- OAuth providers — **out of MVP**, future extension
+
+#### 1.3.2 User Model
+For each project:
+- Users are isolated by `project_id`
+- Store:
+  - `id (uuid)`
+  - `email`
+  - `password_hash (argon2)`
+  - `created_at`
+  - `confirmed_at` (optional)
+  - `user_metadata` (jsonb)
+  - `app_metadata` (jsonb, e.g., provider)
+
+#### 1.3.3 Token Model
+- Access token: JWT, short-lived
+- Refresh token: opaque random string (stored hashed) or JWT-like; must support rotation
+- Required JWT claims to align with RLS expectations:
+  - `sub`
+  - `role` (e.g., `authenticated` / `anon`)
+  - `aud`
+  - `exp`
+  - plus project scoping claim (e.g., `project_ref`)
+
+---
+
+### 1.4 Data API (CRUD, Filtering, Ordering, Pagination)
+MadBase provides PostgREST-like behavior.
+
+#### 1.4.1 CRUD
+- `GET /rest/v1/<table>`
+- `POST /rest/v1/<table>`
+- `PATCH /rest/v1/<table>`
+- `DELETE /rest/v1/<table>`
+
+#### 1.4.2 Query Features
+- `select=*` and nested selects (MVP: basic selects; advanced nested relations phased)
+- Filters:
+  - `eq`, `neq`, `lt`, `lte`, `gt`, `gte`
+  - `like`, `ilike`
+  - `in`
+  - `is` (null checks)
+  - `or` boolean expression support (MVP: limited; expand later)
+- Ordering: `order=col.asc|desc`
+- Pagination:
+  - `limit`, `offset`
+  - Range headers compatibility (nice-to-have if required by supabase-js usage patterns)
+- Count support (`Prefer: count=exact|planned|estimated`) as feasible
+
+#### 1.4.3 RPC
+- Postgres function invocation endpoint compatible with Supabase usage patterns:
+  - `POST /rest/v1/rpc/<function>` (common supabase pattern)
+- Input via JSON body; output as JSON.
+
+#### 1.4.4 RLS Enforcement (Hard Requirement)
+MadBase must rely on **native PostgreSQL RLS**.
+
+For each request within a transaction:
+- Validate JWT (or anon)
+- Set request-local variables:
+  - `SET LOCAL request.jwt.claims = '<json>'` OR granular `SET LOCAL request.jwt.claim.<x>`
+- Set role appropriately:
+  - anon → restricted
+  - authenticated → restricted
+  - service role → bypass policies (by using privileged DB role / bypass behavior)
+
+**Outcome:** Existing Supabase-style RLS policies work unchanged.
+
+---
+
+### 1.5 Realtime (WebSocket Subscriptions)
+MadBase supports Supabase-js subscriptions.
+
+#### 1.5.1 WebSocket Protocol Compatibility
+- `supabase.channel(...).on('postgres_changes', ...)` works unchanged (protocol-level compatibility target)
+- Support channel join/leave, heartbeats, and authorization.
+
+#### 1.5.2 Change Capture
+- Use PostgreSQL logical replication (`pgoutput`)
+- Per-project replication slot management
+- Resume from last confirmed LSN after restart
+
+#### 1.5.3 Filtering + RLS Semantics
+- Enforce subscription filters (table, schema, event types, optional column filters)
+- **RLS-correctness goal**: only stream rows the user is allowed to see.
+  - MVP approach: re-check row visibility by executing a parameterized query under the user’s claims (heavier but correct)
+  - Future: optimize with precomputed policies / projection strategies
+
+---
+
+### 1.6 Object Storage (Supabase Storage-Compatible)
+MadBase provides:
+- Bucket CRUD
+- Object upload/download/delete
+- Signed URL generation (optional)
+- Public/private bucket behavior
+
+#### 1.6.1 Storage Backend
+- Default: MinIO in Podman Compose
+- Production: external S3-compatible endpoint
+- Metadata stored per project in control DB (or optionally tenant DB)
+
+#### 1.6.2 Authorization
+- Requires JWT or anon access depending on bucket policy
+- Service role bypass supported
+
+---
+
+### 1.7 Edge Functions (Full Support, WASM Runtime)
+MadBase supports:
+- `POST /functions/v1/<name>` invocation
+- Deploy/update function artifacts per project
+
+#### 1.7.1 Runtime
+- Wasmtime sandbox execution
+- Per-invocation limits:
+  - max CPU time
+  - max memory
+  - max request body size
+- Environment variables injection:
+  - project ref
+  - supabase URL
+  - anon key (optional)
+  - secrets (encrypted at rest)
+
+#### 1.7.2 Function Packaging
+- MVP: accept WASM modules + manifest
+- Optional toolchain support for TS/JS→WASM documented, but not required in-core.
+
+---
+
+### 1.8 Management UI (Full Project Management)
+UI provides:
+- Project creation/config
+- DB connection configuration test
+- Key management + rotation
+- User management (admin)
+- Storage bucket management
+- Edge function deployment + logs
+- Realtime connection stats
+- RLS policy helpers (optional, best-effort)
+- Health checks
+
+UI talks to `/admin/v1/*` endpoints.
+
+---
+
+### 1.9 Podman Compose Deployment
+Single `docker-compose.yml` (compatible with `podman-compose`) deploys:
+- MadBase API container
+- Control plane Postgres (for project/user/config)
+- MinIO (default storage)
+- Grafana
+- Loki
+- VictoriaMetrics
+
+BYO tenant Postgres DBs are external (not necessarily in compose).
+
+---
+
+## 2. Non-Functional Requirements
+
+### 2.1 Resource Usage Targets
+- **Single-node dev deployment** (compose):
+  - MadBase (idle) memory target: ~100–300MB depending on active WS connections
+  - Minimal CPU when idle
+- Monitoring stack runs within reasonable bounds for small installs.
+
+### 2.2 Performance
+- REST overhead target: low single-digit milliseconds excluding DB time
+- WebSocket fanout efficiency:
+  - handle thousands to tens of thousands connections per node (depending on hardware)
+- Streaming uploads/downloads without buffering entire objects in memory.
+
+### 2.3 Operability (Primary Goal)
+- **Few moving parts**: one Rust service container + standard off-the-shelf observability components.
+- Stateless API layer:
+  - can scale horizontally behind a load balancer
+- Configuration via environment variables + control DB records.
+- Smooth upgrades:
+  - migrations for control plane DB
+  - backward compatible API where possible
+
+### 2.4 Reliability & Availability
+- Graceful shutdown:
+  - drain in-flight requests
+  - close WS connections cleanly
+- Realtime resume:
+  - store last confirmed LSN per project
+- Retry policies for transient DB/storage failures
+- Backpressure handling for WS broadcasts and replication consumption
+
+### 2.5 Security
+- JWT validation strictness (issuer/audience configurable per project)
+- Password hashing: Argon2
+- Secrets encrypted at rest in control DB
+- RBAC for admin UI
+- Edge runtime sandboxing:
+  - no filesystem by default
+  - no network by default (or allowlist)
+- Defense-in-depth:
+  - rate limiting per project/IP
+  - request size limits
+  - CORS configuration
+
+### 2.6 Observability
+- Metrics:
+  - request counts/latency by endpoint and project
+  - DB pool stats
+  - replication lag
+  - WS connections
+  - function invocation duration/errors
+  - storage bytes in/out
+- Logs:
+  - JSON structured logs to stdout
+  - correlation IDs per request
+- Dashboards:
+  - Grafana dashboards included for the above
+
+### 2.7 Maintainability
+- Modular internal crate structure:
+  - `gateway`, `auth`, `data_api`, `realtime`, `storage`, `functions`, `admin`, `control_plane`
+- Clear compatibility test suite using supabase-js integration tests
+- Versioned API surface for `/admin/v1`
+
+---
+
+## 3. Constraints & Assumptions
+
+- MadBase is **API layer only**; it does not provision tenant databases (though it can optionally assist with templates).
+- PostgreSQL is assumed to be standard and supports:
+  - RLS
+  - logical replication (for realtime)
+- Supabase-js compatibility is the north star; where full fidelity is expensive:
+  - MVP supports the most common subset, with explicit “compatibility gaps” tracked.
+
+---
+
+## 4. Acceptance Criteria (Definition of Done)
+
+1. A standard supabase-js app can:
+   - sign up, log in, refresh tokens
+   - perform CRUD with filters/order/pagination
+   - call RPC functions
+   - upload/download storage objects
+   - receive realtime row change events
+   - invoke an edge function
+2. Two projects pointing at two different external Postgres instances are fully isolated.
+3. RLS policies behave identically to Supabase for supported query patterns.
+4. Entire stack deploys via podman-compose and exposes Grafana dashboards with logs+metrics.
