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.

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 primary function of a web server is to store, process and deliver web pages to clients.

Than you must specify witch uri you can manage, you will use server. Another important thing is the management of not found with server. As you can see the response is managed by server. Another very popular library is AsyncWebServer , exist a version for esp and esp32, you must only change the base library. This is fully asynchronous server and as such does not run on the loop thread.

During the loop, we constantly check if a handleroot HTTP request is received by running server.

In the handleRoot function: I have:. But I only see the first line in the browser when handleRoot gets called. If I comment out the first line then the second line gets sent. What am I not understanding? When the browser sees the first send response it processes it and is done.

Add the following snippet to your HTML:. Read up about this project on. The web server is a place to send and receive information, process the information and store it. The web server can also display this information on a web page. When a request is sent to this server for example, its address is searched in the browser , the server returns a code as a response for example, code , which means the connection is established correctly, or code , which indicates that the address is not correct. You can find the full list of these codes here. By entering this IP in your browser you can see the web page you have just created. Two required libraries have been added at the beginning of the code. The WiFi.

If that's the case, we respond with a status Ok and a welcome page. Do you mean handleRoot only opens the connection for a single send per server. If you want to send composite content you can first collect it all in a String and then send it in one go.
