Hello, Dev! In today’s digital age, web servers are the backbone of every online business. A web server is a computer program that responds to requests from web clients (such as web browsers) and serves them with relevant content. Mongoose web server is one such web server that provides a lightweight and robust solution for developers to create web applications. In this article, we will dive deep into the world of Mongoose web server and explore its features, benefits, and use cases.

Getting Started with Mongoose Web Server
Now that you have a good understanding of what Mongoose web server is and what it has to offer, let’s dive into how to get started with it. Here’s a step-by-step guide:
Step 1: Installing Mongoose Web Server
The first step in getting started with Mongoose web server is to install it on your computer. Mongoose web server can be downloaded from the official website (https://mongoose-os.com/) and comes with pre-built binaries for various operating systems.
Once you have downloaded the appropriate binary for your operating system, extract the archive to a directory of your choice. On Windows, you can simply run the “mongoose.exe” executable from the extracted directory to start the web server.
On Linux and Mac, you need to open a terminal and navigate to the extracted directory. Then, you can start the web server by running the following command:
./mongooseAlternatively, you can build Mongoose web server from source by cloning the official GitHub repository (https://github.com/cesanta/mongoose). Building from source requires a C compiler and other development tools, so it may not be suitable for beginners.
Step 2: Creating Your First Mongoose Web Server Application
Once you have Mongoose web server installed, you can start creating your first web application. Mongoose web server provides a simple and intuitive API for creating web applications, which we will explore in detail in the following sections.
For now, let’s create a simple “Hello, World!” web application using Mongoose web server. Here’s the code:
// Include the Mongoose library#include <mongoose.h>// Define the request handler functionstatic void handle_request(struct mg_connection *conn, struct http_message *msg) {// Send the response headersmg_printf(conn, "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n");// Send the response bodymg_printf(conn, "<html><body><h1>Hello, World!</h1></body></html>");}int main() {// Create the server instancestruct mg_mgr mgr;mg_mgr_init(&mgr, NULL);// Create the listenerstruct mg_bind_opts bind_opts;memset(&bind_opts, 0, sizeof(bind_opts));bind_opts.error_string = "Failed to create listener";struct mg_connection *listener = mg_bind_opt(&mgr, "8080", handle_request, bind_opts);// Run the event loopwhile (1) {mg_mgr_poll(&mgr, 1000);}// Clean upmg_mgr_free(&mgr);return 0;}This code creates a simple HTTP server that listens on port 8080 and responds with a “Hello, World!” message when a client makes a request. To run the application, save the code to a file (e.g., “main.c”) and compile it using the following command:
gcc -o main main.c -lmongooseThis will create an executable file called “main” that you can run to start the web server. Open your web browser and navigate to “http://localhost:8080” to see the “Hello, World!” message in action.
Step 3: Exploring Mongoose Web Server’s API
Now that you have created your first web application using Mongoose web server, it’s time to explore its API and see what else it can do. Mongoose web server provides a rich set of functions and data structures for creating web applications, including:
- mg_bind_opt – Creates a listener socket that listens for incoming connections from clients.
- mg_http_send_error – Sends an HTTP error response to the client.
- mg_http_send_redirect – Sends an HTTP redirect response to the client.
- mg_http_send_file – Sends a file to the client over HTTP.
- mg_http_parse_header – Parses an HTTP header from a client request.
- mg_send_websocket_frame – Sends a WebSocket frame to a client.
In addition to these functions, Mongoose web server provides a range of data structures for representing HTTP requests and responses, WebSocket frames, and more. You can find the full API documentation on the official Mongoose web server website (https://mongoose-os.com/docs/).
