This enables its users to efficiently handle different templates and manage dynamic content generation. Another efficient tool of Asynchronous server is a simple template processing engine. ![]() The ServeStatic plugin is also quite helpful as it supports cache, Last-Modified headers, default index, and more to enhance user experience and content delivery.The URL Rewrite plugin enables the users to conditionally or permanently rewrite URLs for flexible routing.Async EventSource plugin (Server-Sent Events) ensures smooth delivery of events to the browser.The Async WebSocket plugin offers its users to use different locations without requiring any extra servers or ports.There are many plugins that enhance the user experience, we have listed some of them below: The Asynchronous server is capable of handling any type of content and supports “continue 100” server code to enhance server client interactions. The API is easy to use and supports HTTP Basic and Digest MD5 Authentication as default options along with Chucked Responses. This allows the server to process individual and several requests with fast speed. In case you have sent a response to the server, the server will start processing the response in the background and keep on taking your next requests. When the request from the client is ready and parsed, a call is generated to notify the client. Overall, an asynchronous server improves performance and enhances the way clients interact with the web server.Īn Asynchronous server can handle multiple connections from different clients at the same time. This means that client requests don’t block each other, and they can be executed concurrently, leading to a smoother and more responsive user experience. Instead, it uses event-driven loops to process the requests from multiple clients simultaneously. On the other hand, with an asynchronous server, there’s no need to create separate threads for each client’s request. In the traditional approach, there can be issues like blocking requests, where the server waits for resources to be freed up, causing delays and negatively affecting the client’s experience. Unlike traditional thread-based servers, which dedicate a separate thread to each client, the asynchronous server operates differently. Asynchronous Web Server Introduction What is Asynchronous Web Server?Īn asynchronous web server is designed to handle XMLHttpRequests in a scalable and efficient way. Asynchronous web servers offer many advantages, as they can efficiently handle multiple connections simultaneously, enhancing the overall performance of your ESP32-based projects. The server operates through HTTP GET requests, allowing data transfer from the user to the server seamlessly. With this web server, you’ll be able to control multiple LEDs connected to ESP32 GPIO pins concurrently. To accomplish this, we’ll be using the ESPAsyncWebServer Library, specifically designed for the ESP32 Dev board in the Arduino IDE. In this tutorial, we will guide you through the process of creating an Asynchronous web server using ESP32 and Arduino IDE. ![]()
