Running Your App

Your first endpoint is ready. Now you can build and run the application using the Mach CLI.

Run the Application

Run your application using the Mach CLI:

mach run

Mach builds the project and starts the application.

Once the server is running, you’ll see output indicating that Mach is listening for requests.

Send a Request

Open your browser and navigate to:

http://localhost:3143/

You should see:

Hello, world!

The request is handled by the endpoint defined in src/main.cpp:

app.mapGet("/", [] {
    return mach::ok("Hello, world!");
});

You’ve now created, built, and run your first Mach application.

Stopping the Application

To stop the running application, return to the terminal and press Ctrl+C.

Where to Go Next

Now that you have a working Mach application, you’re ready to explore more of the framework.

Continue with the guides to learn about routing, controllers, middleware, dependency injection, validation, and other Mach features.
