D1

• D1 Reference

Specify D1 Databases to add to your environment as follows:

const mf = new Miniflare({
	d1Databases: {
		DB: "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
	},
});

For testing, it can be useful to put/get data from D1 storage bound to a Worker. You can do this with the getD1Database method:

const db = await mf.getD1Database("DB");
const stmt = await db.prepare("<Query>");
const returnValue = await stmt.run();

return Response.json(returnValue.results);
