parse-json 5.2.0

The "parse-json" library is an npm package designed to parse JSON data with more user-friendly and informative error messages. Instead of returning a generic error, parse-json provides a detailed error stack which byte-position of the invalid syntax, helping developers to quickly and precisely pinpoint issues in their JSON data. This enhanced level of detail can greatly reduce debugging time and improve coder efficiency.

To use parse-json in JavaScript, you first need to install the package to your project using npm. In your terminal, run the command npm install parse-json. Once installed, import the parse-json function, along with JSONError for error handling, into your script.

Given a JSON string 'json', you can parse it with parse-json as follows.

import parseJson, {JSONError} from 'parse-json';

const json = '{\n\t"foo": true,\n}';

// Use parseJson instead of JSON.parse()
parseJson(json);

To connect a JSON error with a specific file, you can either pass the filename as an argument in the parse-json call, or attach it to the error instance later, like this:

// Passing filename as an argument
parseJson(json, 'foo.json');

// Attaching filename to the error later
try {
    parseJson(json);
} catch (error) {
    if (error instanceof JSONError) {
        error.fileName = 'foo.json';
    }
    throw error;
}

This usage of parse-json enhances error tracing and can make debugging a more targeted process.

Detailed documentation for the parse-json package is available within the readme file at the project's GitHub page: https://github.com/sindresorhus/parse-json. The readme covers installation, usage, and API. For more specific information about the JSON.parse() function and the use of the reviver callback, you can refer to the Mozilla Developer Network documentation linked in the Parse-JSON documentation.
