Welcome to the Ultimate Guide to Mastering Cache Base

Cache Base is a simple and powerful caching library designed to improve the performance of your JavaScript applications. This guide provides dozens of useful API explanations along with code snippets to help you get the most out of Cache Base.

Getting Started with Cache Base

To get started, install Cache Base via npm:

npm install cache-base

Basic Usage

Initialize a Cache instance and use basic methods like set, get, and has:

 const Cache = require('cache-base'); const cache = new Cache();
// Setting a value cache.set('name', 'Cache Base');
// Getting a value const name = cache.get('name'); // 'Cache Base'
// Checking if a key exists const hasName = cache.has('name'); // true 

Advanced Methods

Explore advanced methods like del, union, and clear:

 // Deleting a value cache.del('name');
// Merging values from other caches const otherCache = new Cache(); otherCache.set('age', 25); cache.union(otherCache); console.log(cache.get('age')); // 25
// Clearing all values in the cache cache.clear(); 

Merging Options

Cache Base allows merging of default options:

 const cache = new Cache({
  create: (key, options) => `${key}:${options.namespace}`,
});
cache.set('id123', 'value', { namespace: 'user' }); console.log(cache.get('id123')); // 'id123:user' 

Application Example

Here’s a simple app example that uses Cache Base to cache user data:

 const express = require('express'); const Cache = require('cache-base');
const app = express(); const cache = new Cache();
app.get('/user/:id', (req, res) => {
  const userId = req.params.id;

  if (cache.has(userId)) {
    return res.send(cache.get(userId));
  }

  // Simulate a database lookup
  const userData = { id: userId, name: 'User ' + userId };
  cache.set(userId, userData);

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

Conclusion

Cache Base is a versatile library that can significantly boost your application’s performance by providing an easy-to-use caching solution. From setting basic values to implementing advanced caching strategies, this guide covers various features and practical examples to get you started quickly.
