use D1 DB in worker (no wrangler etc, just JS)

hey there, noobie here. There are multiple tutorials online how to set up the D1 DB with a worker using wrangler, nodejs etc., however i just want to be able to use all the db related stuff within my js file, so no typescript. I went ahead and added the database via DB Database bindings in the settings of the worker, however any request i do in js returns empty data:

const { results } = await env.DB.prepare('SELECT * FROM user').all();
const json = await Response.json(results);
const jjson = JSON.stringify(json);
console.log(jjson);

const { results } = await env.DB.prepare('SELECT * FROM user').all();
const json = await Response.json(results);
const jjson = JSON.stringify(json);
console.log(jjson);

and yes, the DB is called user, the environment variable in the settings is DB. Am i missing something?

Response.json is a static method to return a Response. That isn't something you can stringify.

oh i see. how can i get the db result as a string?

Just remove the const json line Stringifying results is all you need to do

awesome! Thank you very much.

If you're trying to return it to the user, you can do return Response.json(results) from your fetch handler return Response.json(obj) is basically return new Response(JSON.stringify(obj))
