Supabase

Did you set the env variables and are you using a development framework e.g. CRA or nextjs?

I can successfully use this import to query supabase data.

you are accessing the env variables in the client. In order to expose them to the client you have to prefix them with `NEXT_PUBLIC_`

check this out for more information: https://nextjs.org/docs/basic-features/environment-variables#exposing-environment-variables-to-the-browser

and make sure not to expose your supabase service key in the browser by prefixing it with NEXT_PUBLIC  🙂

Thanks a lot, I  set URL and KEY in .env.local
and used in createClient, is this the right way and safe?

If you are referring to the supabase "anon" key by your `NEXT_PUBLIC_SB_KEY`, you ~~should be~~ are fine
