What is nimma?

Nimma is a high-performance JSONPath processor for Node.js. It allows you to efficiently query and manipulate JSON data using JSONPath expressions.

What are nimma's main functionalities?

Query JSON Data

This feature allows you to query JSON data using JSONPath expressions. The code sample demonstrates how to extract the authors of all books in a store.

const Nimma = require('nimma');
const nimma = new Nimma();
const json = { "store": { "book": [ { "category": "reference", "author": "Nigel Rees", "title": "Sayings of the Century", "price": 8.95 }, { "category": "fiction", "author": "Evelyn Waugh", "title": "Sword of Honour", "price": 12.99 } ] } };
const result = nimma.query(json, '$.store.book[*].author');
console.log(result); // Output: [ 'Nigel Rees', 'Evelyn Waugh' ]

Modify JSON Data

This feature allows you to modify JSON data using JSONPath expressions. The code sample demonstrates how to increase the price of all books in a store by 10%.

const Nimma = require('nimma');
const nimma = new Nimma();
const json = { "store": { "book": [ { "category": "reference", "author": "Nigel Rees", "title": "Sayings of the Century", "price": 8.95 }, { "category": "fiction", "author": "Evelyn Waugh", "title": "Sword of Honour", "price": 12.99 } ] } };
nimma.modify(json, '$.store.book[*].price', price => price * 1.1);
console.log(json); // Output: { store: { book: [ { category: 'reference', author: 'Nigel Rees', title: 'Sayings of the Century', price: 9.845 }, { category: 'fiction', author: 'Evelyn Waugh', title: 'Sword of Honour', price: 14.289 } ] } }
