This depends on your use-case. If you're writing a mail agent, then you do probably want to parse email addresses in their entirety. If you're writing a website that accepts email addresses and wants to make sure the user doesn't just type "foo", then yeah, check for `.+@.+` and call it a day.
- runarberg 5y agoIf you are writing a webpage that accepts email addresses, then please just use <input type="email"> and check for: document.querySelector("[type='email']").validity.valid This will not only give you email validation for free, but also gives users with software keyboards (e.g. on phones) a contextual keyboard.
- tokumei 5y agoThat’s just for the client though. Best to check on the server as an authoritative source of truth.
