I am amazed at the enormous power that small WiFi devices, such as esp and esp32, have. They are capable of serving an entire website, and this allows us to do some really cool stuff. A web server is server software, or hardware dedicated to running this software, that can satisfy client requests on the World Wide Web. A web server can, in general, contain one or more websites. A web server processes incoming network requests over HTTP and several other related protocols.

The actual implementation of a web server is much easier than it sounds, because the ESP Arduino Core includes some great libraries that handle pretty much everything for you. Let's look at a basic Hello World! The actual server code is pretty straightforward. First, we create a server instance that listens for HTTP requests on port This is the default port for web servers. In the setup, we tell the server what to do with certain HTTP requests. We put this in a function as well, and use server. Then we start listening for HTTP requests by using server. During the loop, we constantly check if a new HTTP request is received by running server. If handleClient detects new requests, it will automatically execute the right functions that we specified in the setup. You should get a webpage saying Hello world!
