wrangler.toml
[[d1_databases]]

​Working with D1 Databases

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 { results } = await db.prepare("<Query>");

console.log(await res.json(results));
