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

1'use strict'
2
3var parse = require('fast-json-parse')
4var fs = require('fs')
5
6var result = parse(fs.readFileSync('./package.json', 'utf8'))
7
8if (result.err) {
9  console.log('unable to parse json', result.err.message)
10} else {
11  console.log('json parsed successfully', result.value)
12}

constructor

1'use strict'
2
3var Parse = require('fast-json-parse')
4var fs = require('fs')
5
6var result = new Parse(fs.readFileSync('./package.json'))
7
8if (result.err) {
9  console.log('unable to parse json', result.err.message)
10} else {
11  console.log('json parsed successfully', result.value)
12}
