fast-json-parse

It is equivalent to json-parse-safe, but it set both the err and value property to null.

The reason why this is fast is that try/catch inhibits the functions in which you use them to be optimized. This assumption holds true up to Node 6, from Node 7 and forward this module is not useful anymore.

Install

npm i fast-json-parse --save

Usage

You can use it as a function or via a contructor, as you prefer.

function

'use strict'
 
var parse = require('fast-json-parse')
var fs = require('fs')
 
var result = parse(fs.readFileSync('./package.json'))
 
if (result.err) {
  console.log('unable to parse json', result.err.message)
} else {
  console.log('json parsed successfully', result.value)
}

constructor

'use strict'
 
var Parse = require('fast-json-parse')
var fs = require('fs')
 
var result = new Parse(fs.readFileSync('./package.json'))
 
if (result.err) {
  console.log('unable to parse json', result.err.message)
} else {
  console.log('json parsed successfully', result.value)
}
