Hello World

The Hello World function is a simple function that returns the string "Hello [name]!", where [name] is either the value provided in the name query parameter for a GET request or the value provided in the name field of the request body for a POST request.

The function uses the event and context parameters and logs them to the console. It handles both GET and POST requests and returns a JSON response with a message field containing the personalized greeting.

The source code for the function:

// GET requests to /filename?name=<name> would return "Hello, <name>!"
export const onRequestGet = async ({request}) => {
    const urlParams = new URL(request.url || "").searchParams;
    const name = urlParams.get("name") || "World";

    return new Response(JSON.stringify({
        message: `Hello, ${name}!`
    }));
};

// POST requests to /filename with a JSON-encoded body would return "Hello, <name>!"
export const onRequestPost = async ({request}) => {
    const {name} = await request.json();

    return new Response(JSON.stringify({
        message: `Hello, ${name}!`
    }));
};
