+# Mayaspace Backend
+
+Mayaspace Backend is a federated social network backend implementation that follows the **ActivityPub** protocol. It includes user registration, password authentication using JWT tokens, post creation, and following activities. It uses **SQLite** via the `quick.db` library for data storage.
+
+## Features
+
+- **Federated**: Supports ActivityPub protocol to allow federated communication with other ActivityPub-compatible platforms.
+- **Password Authentication**: User authentication with password hashing (using bcrypt) and JWT tokens.
+- **SQLite Backend**: Data storage using SQLite via `quick.db`.
+- **RESTful API**: Basic routes for user registration, login, post creation, and followers management.
+
+## Technologies
+
+- **Node.js** for backend.
+- **Express.js** for routing and middleware.
+- **ActivityPub-Express** for ActivityPub protocol handling.
+- **quick.db** for persistent SQLite storage.
+- **bcryptjs** for password hashing.
+- **jsonwebtoken** for user authentication and token management.
+- **uuid** for unique post IDs.
+- **node-fetch** for making federated requests.
+
+## Installation and Setup
+
+Follow these steps to set up the Mayaspace Backend locally:
+
+### Prerequisites
+
+- Install **Node.js** (v14.0.0 or above).
+- Ensure **npm** is installed.
+
+### 1. Clone the Repository
+
+First, clone the project to your local machine:
+
+```bash
+git clone https://github.com/yourusername/mayaspace-backend.git
+cd mayaspace-backend
+```
+
+### 2. Install Dependencies
+Install the required dependencies using npm:
+
+```bash
+npm install
+```
+
+This will install the following dependencies:
+
+activitypub-express: For handling ActivityPub protocol.
+bcryptjs: For securely hashing passwords.
+body-parser: For parsing incoming request bodies.
+jsonwebtoken: For managing JWT tokens.
+quick.db: For SQLite storage.
+uuid: For generating unique post IDs.
+node-fetch: For federated network communication.
+express: For building the API server.
+
+### 3. Run the Server
+Start the backend server:
+
+```bash
+npm start
+```
+
+This will run the backend on http://localhost:3000.
+
+### 4. API Endpoints
+Here are the main API endpoints available:
+
+User Registration
+Create a new user (actor) with a username, display name, and password.
+
+```bash
+POST /users
+```
+
+Request Body:
+
+```json
+{
+  "username": "alice",
+  "displayName": "Alice",
+  "password": "password123"
+}
+```
+
+#### User Login
+Authenticate the user and get a JWT token.
+
+```bash
+POST /login
+```
+
+Request Body:
+
+```json
+{
+  "username": "alice",
+  "password": "password123"
+}```
+
+Response:
+
+```json
+{
+  "token": "<JWT_TOKEN>"
+}```
+#### Create a Post (Status Update)
+Create a post (note) for the authenticated user. Authentication is required using the JWT token in the Authorization header.
+
+```bash
+POST /users/:username/posts
+````
+Request Body:
+
+```json
+{
+  "content": "Hello, federated world!"
+}
+```
+#### Get User's Posts
+Fetch posts for the authenticated user. Authentication is required using the JWT token in the Authorization header.
+
+```bash
+GET /users/:username/posts
+```
+#### ActivityPub - Follow
+This endpoint handles incoming follow activities for federated interactions.
+
+```bash
+POST /users/:username/inbox
+Request Body:
+```
+
+```json
+{
+  "type": "Follow",
+  "actor": {
+    "id": "http://example.com/users/bob"
+  }
+}
+```
+
+### 5. Testing the API
+To test the API, you can use Postman or cURL to make requests.
+
+Here are some example cURL commands to test the basic functionality:
+
+### Create a new user:
+```bash
+curl -X POST http://localhost:3000/users -H "Content-Type: application/json" -d '{"username": "alice", "displayName": "Alice", "password": "password123"}'```
+
+#### Login to get a token:
+```bash
+curl -X POST http://localhost:3000/login -H "Content-Type: application/json" -d '{"username": "alice", "password": "password123"}'```
+
+#### Create a post (Authenticated):
+```bash
+curl -X POST http://localhost:3000/users/alice/posts -H "Content-Type: application/json" -H "Authorization: Bearer <YOUR_JWT_TOKEN>" -d '{"content": "Hello, federated world!"}'
+```
+
+#### Get posts (Authenticated):
+```bash
+curl http://localhost:3000/users/alice/posts -H "Authorization: Bearer <YOUR_JWT_TOKEN>"
+```
+### 6. Federated Interaction
+If you want to integrate with other federated servers, you can send ActivityPub requests to follow users on other servers or receive activities through the /users/:username/inbox endpoint.
