Frequently Asked Questions

What does json-parse-even-better-errors do?

The npm package "json-parse-even-better-errors" is a Node.js library that improves the functionality of JSON.parse(). It provides more informative and easier to understand error messages which include the context and location of parse errors. It also takes care to preserve the newline and indentation styles present in the JSON data. These styles are kept in the object or array in Symbol.for('indent') and Symbol.for('newline') properties. This package can be particularly useful for developers who work with JSON data frequently and need a better way to handle and decipher errors.

How do you use json-parse-even-better-errors?

Here's how you can start using json-parse-even-better-errors. First, you need to install the package:

$ npm install --save json-parse-even-better-errors

Then, you can require it in your code like so:

const parseJson = require('json-parse-even-better-errors')

You can use it to parse JSON in a way similar to the JSON.parse() method, but with better errors:

parseJson('"foo"') // returns the string 'foo'
parseJson('garbage') // this will throw a more informative error message 

The package also provides a noExceptions method that returns undefined instead of throwing an error :

parseJson.noExceptions('garbage') // returns undefined

If you want to preserve JSON data indentation and newline character(s) when saving the file back to disk, you could use the following code:

const txt = await readFile('./package.json', 'utf8')
const data = parseJsonEvenBetterErrors(txt)
const indent = Symbol.for('indent')
const newline = Symbol.for('newline')
// .. do some stuff to the data ..
const string = JSON.stringify(data, null, data[indent]) + '\n'
const eolFixed = data[newline] === '\n' ? string
  : string.replace(/\n/g, data[newline])
await writeFile('./package.json', eolFixed)
