Catch exception in node during JSON.parse
It's all good! :-)
JSON.parse runs synchronous and does not know anything about an err parameter as is often used in Node.js. Hence, you have very simple behavior: If JSON parsing is fine, JSON.parse returns an object; if not, it throws an exception that you can catch with try / catch, just like this:
webSocket.on('message', function (message) { var messageObject; try { messageObject = JSON.parse(message); } catch (e) { return console.error(e); } // At this point, messageObject contains your parsed message as an object.}That's it! :-)
