The first part of the phrase, https://localhost:11501 , is the technical heart of the matter. The port number 11501 is arbitrary—a stand-in for any local development server. The real innovation is the https . Traditionally, secure sockets layer (SSL/TLS) certificates were for domains with public DNS records. They validated that a server (e.g., yourbank.com ) was who it claimed to be. But localhost resolves to the loopback address 127.0.0.1 —your own computer. Why encrypt a conversation you are having with yourself? The answer lies in . Modern browsers increasingly gatekeep powerful features—Service Workers, Geolocation, the Web Crypto API—behind a secure context. Without https , your local app cannot mimic the production environment. Worse, a development server running on plain http might be vulnerable to a "localhost override" attack, where malicious local software listens in. Thus, we impose the rigors of the public web onto our private workspace. https localhost11501 verified
