Minor Changes

  • #11942 133bf95 Thanks @​penalosa! - Add support for Email Sending API's MessageBuilder interface in local mode

    Miniflare now supports the simplified MessageBuilder interface for sending emails, alongside the existing EmailMessage support.

    Example usage:

    await env.EMAIL.send({
    	from: { name: "Alice", email: "[email protected]" },
    	to: ["[email protected]"],
    	subject: "Hello",
    	text: "Plain text version",
    	html: "<h1>HTML version</h1>",
    	attachments: [
    		{
    			disposition: "attachment",
    			filename: "report.pdf",
    			type: "application/pdf",
    			content: pdfData,
    		},
    	],
    });

    In local mode, email content (text, HTML, attachments) is stored to temporary files that you can open in your editor or browser for inspection. File paths are logged to the console when emails are sent.
