Generate Guid or UUID

So, how do we generate a Guid or UUID in TypeScript and Angular? C# is kind enough to provide us a built-in, but in Angular, we have to install the package!

If we do not want to install anything and quickly just generate a random Guid then we can simply do this:

generateGUID() {
  return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
    var r = Math.random() * 16 | 0,
      v = c == 'x' ? r : (r & 0x3 | 0x8);
    return v.toString(16);
  });
}

This will return a Guid as a string 👌

Now let's do the reverse... let's check if the string is a Guid:

isStringGuid(guidAsString: stirng){
  const guidRegex = /^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}$/;

  if (guidRegex.test(guidAsString)) {
    console.log(`${guidAsString} is Guid`);
  }
  else {
    //Handle the case when it is not a GUID
    console.log("Nope! It is not!");
  }
}
