In Node.js

// ESM:
import { safeJsonDecode, safeJsonEncode } from 'safe-json-decode';
// CommonJS:
const { safeJsonDecode, safeJsonEncode } = require('safe-json-decode');

Usage

// Same behavior as JSON.parse with valid JSON
safeJsonDecode('{ "foo": "bar" }'); // => {foo: 'bar'}
// Returns null if JSON.parse fails
safeJsonDecode('{ invalid }'); // => null


// Same behavior as JSON.stringify with value that can be serialized
safeJsonEncode({ foo: 'bar' }); // => '{"foo": "bar"}'
// Returns null if JSON.stringify fails
const objectWithCircularReference = {};
objectWithCircularReference.self = objectWithCircularReference;
safeJsonEncode(objectWithCircularReference);


// Handle side effects if error is caught

const handleError = (error) => console.error(error);

safeJsonDecode('{ invalid }', undefined, handleError); 
safeJsonEncode(objectWithCircularReference, undefined, undefined, handleError);
