Introduction to Cache Base

Cache Base is a powerful caching library designed to optimize data retrieval and storage processes. With its extensive API offerings, it provides developers with the tools they need to efficiently manage cached data, reduce load times, and improve overall application performance. In this article, we’ll explore dozens of useful APIs provided by Cache Base, complete with code snippets and a comprehensive application example. Let’s dive in!

Getting Started with Cache Base

To get started, you need to install Cache Base via npm:

  
    npm install cache-base
  

API Examples

Creating a Cache

  
    const Cache = require('cache-base');
    const cache = new Cache();
  

Setting a Value

  
    cache.set('foo', 'bar');
  

Getting a Value

  
    let value = cache.get('foo'); // 'bar'
  

Checking for Existence

  
    let exists = cache.has('foo'); // true
  

Removing a Value

  
    cache.del('foo');
  

Clearing the Cache

  
    cache.clear();
  

Using Namespaces

  
    const nsCache = cache.namespace('namespace1');
    nsCache.set('foo', 'bar');
    let value = nsCache.get('foo'); // 'bar'
  

App Example

Let’s integrate the Cache Base into a simple Express.js app:

  
    const express = require('express');
    const Cache = require('cache-base');
    const app = express();
    const cache = new Cache();

    app.get('/set', (req, res) => {
      cache.set('greeting', 'Hello, World!');
      res.send('Value set in cache');
    });

    app.get('/get', (req, res) => {
      let value = cache.get('greeting') || 'No value found!';
      res.send(value);
    });

    app.get('/clear', (req, res) => {
      cache.clear();
      res.send('Cache cleared');
    });

    app.listen(3000, () => {
      console.log('Server is running on port 3000');
    });
  

With these simple endpoints, you can easily manage cached data and integrate powerful caching mechanisms into your applications, all thanks to Cache Base.
