json-parse-safe

Like JSON.parse, but doesn't throw on invalid JSON.

Usage

Takes the same arguments as JSON.parse.

``js
const parse = require('json-parse-safe');
const validJson = '{ "foo": "bar" }';
const invalidJson = 'foo';

// Simple usage
console.log(parse(validJson)); // { foo: 'bar' }
console.log(parse(invalidJson)); // null

// Pass a reviver just like the real JSON.parse
parse('{"p": 5}', (key, value) =>
typeof value === 'number'
? value 2 // return value 2 for numbers
: value // return everything else unchanged
);
// { p: 10 }

// choose a defaultValue for invalid json
console.log(parse(invalidJson, undefined, 'WHOOPS')); // 'WHOOPS'
