By Caching JSON Data
To increase the speed of an application and reduce the number of network requests, it is possible to cache JSON data locally. Here are a some methods:
- Saving JSON responses to local storage or session storage.
- Integrating client-side caching systems such as IndexedDB or Web Storage.
- Using service workers that can intercept and store JSON requests for offline use.
Syntax:
localStorage.setItem('jsonData', JSON.stringify(data));
Example: To demonstrate storing the JSON data locally.
const data = {
"name": "Johny",
"age": 23,
"city": "Lucknow",
"country": "India"
};
localStorage.setItem('data', JSON.stringify(data));
// Accessing the item from localStorage
setTimeout(() => {
const retrievedData = localStorage.getItem('data');
console.log(JSON.parse(retrievedData));
}, 1000);
Output:
{"name":"Johny","age":23,"city":"Lucknow","country":"India"}
How to Optimize JSON Performance in JavaScript Applications?
JSON or JavaScript Object Notation is a lightweight data format that is usually used in transmitting data between the server and client end of web applications. It may cause performance problems if not handled properly, particularly when working with large datasets in programs. So, let’s see how to improve JSON performance in JavaScript.
