Tbase - Simple Socket-Based Backend Library

npm License

Tbase is a lightweight, socket-based backend solution packed into a single npm library. With just one Client class and a prebuilt server, you can set up a fully functional backend in as little as 10 lines of code. No need for complex API routes or server modifications—Tbase handles it all out of the box.

Demo at: Github

Key Features

Real-Time Sockets: Built-in WebSocket support for effortless real-time communication.
Database Support: Seamless integration with MongoDB (NoSQL) and MySQL (SQL).
Authentication: JWT-based sign-up/sign-in with session management.
Database Actions: Prebuilt CRUD operations (get, add, update, delete) with real-time updates.
User Management: Permissions, teams, and online user tracking.
File Storage: Bucket-based file API for uploads and management.
Push Notifications: Cross-platform notifications with VAPID and APNs support.
SSR & CSR: Works on both server-side rendering (SSR) and client-side rendering (CSR).
Frontend Freedom: Control everything from the frontend—no backend setup required.
Permission and Preferences: On account and users-scope.
Mailer: Send mails and handle user verifications on the frontend. (in development.)

Getting Started

Installation

Install Tbase via npm: (still in development)

npm install @tomkoooo/tbase

Basic Setup

Tbase provides a Client class as the main entry point. Initialize it with optional WebSocket server URI (defaults to localhost:3000 if not specified).

const { Client } = require('tbase');

// Basic client setup
const client = new Client(); // Uses default server at localhost:3000

YOU NEED THIS SERVER.JS FOR THE WEBSOCKET CONNECTION get the server.js file (nextjs) Change the imports for the npm package.

#### Database Connection Connect to MongoDB or MySQL with a simple configuration:

MongoDB:

export const mongoClient = new Client()
  .database('mongodb')
  .connection({
    url: 'mongodb://localhost:27017',
    dbName: 'socket-test',
  });

MySQL:

export const mysqlClient = new Client()
  .database('mysql')
  .connection({
    host: 'localhost',
    user: 'root',
    port: 3306,
    database: 'socket-test',
  });

Once connected, you're linked to both the socket server and your database!

Core Features

1. Socket Communication

Real-time communication is at the heart of Tbase. Use these methods to interact with sockets:

Subscribe/Listen: Listen to events on a specific channel.

client.subscribe('chat', (message) => {
  console.log('Chat message:', message);
});

Unsubscribe: Stop listening to a channel.

client.unsubscribe('chat');

Send: Emit data to a channel.

client.send('chat', 'Hello, world!');

Example (React):

useEffect(() => {
  client.subscribe('chat', (message) => {
    setMessages((prev) => [...prev, message.message]);
  });
  return () => client.unsubscribe('chat');
}, []);

2. Database Operations

Perform CRUD operations with real-time updates using the ActionBuilder:

Get Data:

mongoClient
  .get('users')
  .query("collection('users').find().toArray()")
  .setState(setUsers) // Optional: Update state based on the CRUD method
  .callback((response) => console.log('Response:', response))
  .execute();

Other Actions: Use add, update, or delete similarly. Raw Query:

mysqlClient.execute('users', 'SELECT * FROM users', (data) => console.log(data));

3. Authentication (client.account())

Manage user authentication with ease:

Sign Up/Sign In:

databaseClient.signUp('user@example.com', 'password', (data) => console.log(data));
databaseClient.signIn('user@example.com', 'password', (data) => console.log(data));
databaseClient.validate('jwt_string' (data) => console.log(data)); //gives back the user by provided jwt

Returns a JWT (stored in localStorage) and session ID (stored in cookies) under t_auth.

Get User:

databaseClient.account().get((user) => console.log(user));

Returns a user object if there is a valid JWT token stored

Session Management: Use getSession, killSession, setSession, etc

public getSessions: (callback: (data: any) => void)
- Gives back all the user's sessions if there is a valid JWT registered
- Note: on server-side use the database class and on that the getSessions method with the userId as a parameter
public setSession: (sessionData: string, callback: (data: any) => void)
- Register a new session with the sessionData string if there is a valid JWT
- Note: on server-side use the database class and on that the setSession method with the userId and the new sessionId string as a parameter
public killSession: (callback: (data: any) => void)
- Kills the user current session from the database and removes the tokens from localStorage and cookies
- Note: on server-side use the database class and on that the kilSession method with the sessionId as a parameter
public killSessions: (callback: (data: any) => void)
- Kills the user's all session from the database and removes the tokens from localStorage and cookies
- Note: on server-side use the database class and on that the kilSessions method with the userId as a parameter
public changeSession: (newSessionString: sring, callback: (data: any) => void)
- Changes the user's current session if there is a valid JWT Note: It not updates the cookies
- Note: on server-side use the database class and on that the changeSession method with the changable sessionId and the new sessionId as a parameter

4. User Management (client.users())

Requires an active JWT session: List Users:

databaseClient.users().listAll((users) => console.log(users));
databaseClient.users().getUser('userId2', (users) => console.log(users)); // gives back specific user obj
databaseClient.users().getUsers(['userid1', 'userid2'], (users) => console.log(users)); // gives back users obj in an array by their userId from a list
databaseClient.users().listOnline((onlineUsers) => console.log(onlineUsers));
//Note a user can be online if after socket connection there is a getAccount or getSession call (client-sde authentication)

Real-Time Online Users:

client.users().listenOnlineUsers((users) => console.log(users));

5. File Storage (Bucket API)

Store and manage files in buckets: JWT session needed

Create Bucket:

const bucketId = await databaseClient.createBucket();

Upload File:

await databaseClient.uploadFile(bucketId, { name: 'file.txt', type: 'text/plain', data: buffer });

List Files:

const files = await databaseClient.listFiles(bucketId);

Other calls:

await databaseClient.deleteFile(bucketId, fileId); //deletes a file in the bucket
const buckets = await databaseClient.listBuckets(); //list of all existing buckets in the db
await databaseClient.deleteBucket(bucketId); //deletes the corresponfing bucket table
await databaseClient.renameBucker(bucketId, newBucketString); //renames the bucket Note: new name = bucket_{newNameString}

6. Push Notifications

Enable notifications with VAPID keys (and optional APNs for Apple):

Subscribe/unsubscribe:

client.subscribeToNotification('user123');
client.unsubscribeFromNotification('user123');

Send Notification:

client.sendNotification('user123', { title: 'Hello', message: 'New update!' }); //sends notification with the corresponding user based on userId

### 7. Server-Side Rendering (SSR) Use the Database class for server-side operations:

const { Database, MongoDB } = require('tbase');

const db = new Database(new MongoDB({
  url: 'mongodb://localhost:27017',
  dbName: 'socket-test',
}));

// Get user session
export const getSession = async (sessionId) => {
  return await db.getSession(sessionId);
};

avaible methods under database: db.{method name}

account

async signUp(payload: {email: string, password: string})
async signIn(email, password)
async getAccount(userId)
async getSession(sessionId)
async getSessions(userId)
async setSession(userId, sessionId)
async killSession(sessionId)
async killSessions(userId)
async changeSession(sessionId, newSessionId)

users

async getUser(userId)
async getUsers(userIds)
async listUsers()

Notification

async storeSubscription(userId, subscription)
- subscription obj generated by the notification class
async upsert(table, data)
- updates/inserts the subscription from the notification class
async delete(table, query)
- deletes a subscription from the notification class
async find(table, query)
- finds a table and gives back every data that are in it
- used to retreive subscriptions in the notification clasy

Bucket

async createBucket()
async uploadFile(bucketId, file)
async getFile(bucketId, fileId)
async listFiles(bucketId)
async deleteFile(bucketId, fileId)
async listBuckets()
async deleteBucket(bucketId)
async renameBucket(oldBucketId, newBucketId)

Permissions

item permissions
- async createPermission(itemId, requireAction, requireRole = null)
- async getPermission(permissionId)
- async getPermissions(itemId = null)
- async updatePermission(permissionId, itemId, requireAction, requireRole = null)
- async deletePermission(permissionId)
user permissions
