What is parse-json?

The parse-json npm package is used for parsing JSON strings. It provides an API for parsing JSON with more helpful error messages than the native JSON.parse. It can also handle trailing commas and comments in JSON strings, which are not supported by the standard JSON.parse.

What are parse-json's main functionalities?

Parse JSON with better error messages

This feature allows users to parse JSON strings and get more informative error messages when the JSON is invalid. It helps in debugging and fixing the JSON content.

const parseJson = require('parse-json');

try {
  const obj = parseJson('{"foo": true,}');
} catch (error) {
  console.error(error.message);
}

Parse JSON with comments

parse-json can handle JSON strings that contain comments, which are not typically allowed in JSON. This is useful when dealing with configurations or other JSON files where comments might be present.

const parseJson = require('parse-json');

const jsonWithComments = '{/* comment */ "foo": true}'
const obj = parseJson(jsonWithComments);

Parse JSON with trailing commas

This feature allows the parsing of JSON strings that have trailing commas after the last element in an object or array, which is not permitted in standard JSON.

const parseJson = require('parse-json');

const jsonWithTrailingComma = '{"foo": true,}'
const obj = parseJson(jsonWithTrailingComma);
