Effortlessly manage API data with this flexible caching class. Auto-update, built-in cache expiration, and simple interface optimize data processing for all projects.

Data Caching Class

A class for caching data from API requests in Node.js. This class makes use of the fs and fetch modules to store and retrieve data, respectively. The cached data is saved to a JSON file, and the class will automatically check the cache's expiration time and refresh the data as necessary.

Features

• Automatically refreshes data when cache has expired
• Uses fs module to save and load cache data
• Throws an error if no token is provided

Usage

The class can be imported and instantiated in your Node.js code as follows:

const Data = require('./data');  
const data = new Data();

The Data class has the following methods:

autoUpdate(token, minutes = 1)

Starts the auto-update process, which checks the cache every minutes interval.

• token (required): API token for making requests
• minutes (optional, default 1): interval in minutes to check cache, default is 1

update(token)

Updates the cache on call with new data, bypassing the cacheExpiry Timer.

• token (required): API token for making requests

getData(token)

Gets the data and updates the cache if necessary.

• token (required): API token for making requests

Example

Here is a complete example of how to use the Data class:

const Data = require('./data'); 
const data = new Data(); 
const token = 'your_api_token';  

// Get the data 
data.getData(token).then((data) => { console.log(data); });`
