Send an HTTP request using fetch

Bun implements the Web-standard fetch API for sending HTTP requests. To send a simple GET request to a URL:

const response = await fetch("https://bun.com");
const html = await response.text(); // HTML string

---

To send a POST request to an API endpoint.

const response = await fetch("https://bun.com/api", {
  method: "POST",
  body: JSON.stringify({ message: "Hello from Bun!" }),
  headers: { "Content-Type": "application/json" },
});

const body = await response.json();
