BhaiClient Package Documentation

Overview

BhaiClient is a versatile and efficient solution for applications needing fast, reliable, and persistent data storage using MongoDB and in-memory caching.

Installation

npm install bhaiclient

Getting Started

Importing and Initializing

import BhaiClient from 'bhaiclient';

const client = new BhaiClient({
  mongoConfigs: [{ uri: 'your_mongo_connection_string', dbName: 'your_database_name' }],
  ttl: 3600, // Time-to-Live for cache entries in seconds
  logger: (message) => console.log('LOG:', message),
  errorHandler: (error) => console.error('ERROR:', error.message)
});

Connecting to MongoDB

(async () => {
  await client.connectToMongo();
})();

API Reference

1. connectToMongo()

Connects to the MongoDB instances specified in the configuration.

await client.connectToMongo();

2. getData(collectionName, key)

Retrieves data from the cache or MongoDB.

• collectionName: The name of the MongoDB collection.
• key: The key to retrieve.

const data = await client.getData('your_collection', 'testKey');
console.log(data);

3. setData(collectionName, key, value)

Sets data in the cache and MongoDB.

• collectionName: The name of the MongoDB collection.
• key: The key to set.
• value: The value to set.

await client.setData('your_collection', 'testKey', { some: 'data' });

4. deleteData(collectionName, key)

Deletes data from the cache and MongoDB.

• collectionName: The name of the MongoDB collection.
• key: The key to delete.

await client.deleteData('your_collection', 'testKey');

Example Scenarios

Real-Time Applications (Chat Application)

import BhaiClient from 'bhaiclient';

(async () => {
const client = new BhaiClient({
    mongoConfigs: [{ uri: 'your_mongo_connection_string', dbName: 'your_database_name' }],
    ttl: 3600, // 1 hour TTL for chat messages
    logger: (message) => console.log('LOG:', message),
    errorHandler: (error) => console.error('ERROR:', error.message)
  });

  await client.connectToMongo();

  // Set chat message
  await client.setData('chat', 'message123', { from: 'user123', to: 'user456', message: 'Hello!' });

  // Get chat message
  const message = await client.getData('chat', 'message123');
  console.log('Chat Message:', message);

  // Delete chat message
  await client.deleteData('chat', 'message123');
})();

IoT (Sensor Data)

import BhaiClient from 'bhaiclient';

(async () => {
  const client = new BhaiClient({
    mongoConfigs: [{ uri: 'your_mongo_connection_string', dbName: 'your_database_name' }],
    ttl: 600, // 10 minutes TTL for sensor data
    logger: (message) => console.log('LOG:', message),
    errorHandler: (error) => console.error('ERROR:', error.message)
  });

  await client.connectToMongo();

  // Set sensor data
  await client.setData('sensors', 'sensor123', { temperature: 22.5, humidity: 60 });

  // Get sensor data
  const sensorData = await client.getData('sensors', 'sensor123');
  console.log('Sensor Data:', sensorData);

  // Delete sensor data
  await client.deleteData('sensors', 'sensor123');
})();

E-commerce (User Cart)

import BhaiClient from 'bhaiclient';

(async () => {
  const client = new BhaiClient({
    mongoConfigs: [{ uri: 'your_mongo_connection_string', dbName: 'your_database_name' }],
    ttl: 86400, // 1 day TTL for user carts
    logger: (message) => console.log('LOG:', message),
    errorHandler: (error) => console.error('ERROR:', error.message)
  });

  await client.connectToMongo();

  // Set user cart
  await client.setData('carts', 'user123', { items: [{ productId: 'prod123', quantity: 2 }] });

  // Get user cart
  const cart = await client.getData('carts', 'user123');
  console.log('User Cart:', cart);

  // Delete user cart
  await client.deleteData('carts', 'user123');
})();

Events

set

Emitted when data is set.

client.on('set', (key, data) => {
  console.log(`Data set for key: ${key}`, data);
});

get

Emitted when data is retrieved.

client.on('get', (key, data) => {
  console.log(`Data retrieved for key: ${key}`, data);
});

delete

Emitted when data is deleted.

client.on('delete', (key) => {
  console.log(`Data deleted for key: ${key}`);
});

cacheMiss

Emitted when a cache miss occurs.

client.on('cacheMiss', (key) => {
  console.log(`Cache miss for key: ${key}`);
});

Performance

The performance of the BhaiClient package largely depends on your use case, hardware, network latency, and data volume. However, overall, this package is fast and efficient due to its combination of in-memory caching and MongoDB.

Expected Performance

• setData: Typically takes a few milliseconds, depending on MongoDB write speed.
• getData: If data is in cache, it takes less than 1 millisecond. If data is fetched from MongoDB, it takes a few milliseconds.
• deleteData: Typically takes a few milliseconds, depending on MongoDB delete speed.

Improving Performance

1. Optimize MongoDB Indexing: Ensure that your MongoDB collections have appropriate indexes to speed up queries.
2. Increase Cache TTL: Increase the Time-to-Live (TTL) for cache entries to reduce the frequency of fetching data from MongoDB.
3. Use Efficient Data Structures: Use efficient data structures and algorithms to manage data within your application.
4. Monitor Performance: Use monitoring tools to track the performance of your MongoDB cluster and in-memory cache.
