parseJson

Type : function

This function simplifies parsing a string as JSON. It wraps the native JSON.parse function in a try-catch block to handle errors automatically. If the string cannot be parsed as JSON, it returns undefined; otherwise, it returns the parsed value.

Usage

type User = {
  name: string;
  email: string;
}

const user = parseJson<User>(userDataString);

if (user) {
  console.log(user) // { name: 'user name', email: 'user email' }
} else {
  console.log(user) // undefined
}
