is-json

check if a string is a valid JSON string without using Try/Catch and is a JSON object

V1.2

isJSON(str*, [passObjects=bool])

*with passObjects = true can pass a JSON object in str, default to false

  var isJSON = require('is-json');

  var good_json = '{"a":"obja","b":[0,1,2],"c":{"d":"some object"}}';
  var bad_json = '{"a":"obja""b":[0,1,2],"c":{"d":"some object"}}';
  var str_number = '121212';


  console.log(isJSON(good_json)); // true
  console.log(isJSON(bad_json)); // false
  console.log(isJSON(str_number)); // false



  // check is an object

  var object = {a: 12, b: [1,2,3]};

  console.log(isJSON(object, true)); // true

// can use isJSON.strict (uses try/catch) if wants something more robust

console.log(isJSON.strict('{\n "config": 123,\n "test": "abcde" \n}')); // true
