Live Reload

Miniflare automatically refreshes your browser when your Worker script changes when liveReload is set to true.

const mf = new Miniflare({
	liveReload: true,
});

Miniflare will only inject the <script> tag required for live-reload at the end of responses with the Content-Type header set to text/html:

export default {
	fetch() {
		const body = `
      <!DOCTYPE html>
      <html>
      <body>
        <p>Try update me!</p>
      </body>
      </html>
    `;

		return new Response(body, {
			headers: { "Content-Type": "text/html; charset=utf-8" },
		});
	},
};
