A utility method to get the line & column to which a JSON pointer points in a given JSON string.

More information about JSON pointers in the RFC6901;

This package is no longer maintained.

The last version is the 1.0.2 from 2026/03/24.

The module only contains one method, use it like this:

const { getLineNumber } = require('jp2p');
const jsonString = '{\n  "toto": "tata"\n}';

console.log(getLineNumber(jsonString, '/toto'));

In this case it will output { line: 2, column: 10 }. The line in the jsonString at which the element at JSON pointer /toto is defined.
