npm install json-parse --save

You can also use Duo, Bower or download the files manually.

Similar to try { return JSON.parse } … but more functional and compositionally friendly.

var parse = require('json-parse')
 
parse([])('[1,2,3]')
//=> [ 1, 2, 3 ] 
 
parse([])('[1,2,3')
//=> [] 
var parse = require('json-parse')
 
Promise.resolve('[1,2,3]')
.then(parse([]))
.then(sum)
//=> 6 
 
Promise.resolve(undefined)
.then(parse([]))
.then(sum)
//=> 0 
  • defaultValue (*) Default value to return if given data does not parse as valid JSON.
