supabase-mailer VS SupaScript

Supabase developer here. Just to clarify, Supabase has server-side functions (edge functions), emails can be sent with something like my repo here (https://github.com/burggraf/supabase-mailer) or through edge functions -- but you're right, while we do have the ability to send any auth-related emails built-in (sign up, sign in with magic link, MFA, reset password, etc.) we don't have an out-of-the-box solution for sending emails, that's why I wrote that repo. And lastly, it's quite easy to schedule tasks using pg_cron, which is built into every Supabase project by default.

Hello, I've tried these instructions https://github.com/burggraf/supabase-mailer/blob/main/Mail_Providers/Sendgrid.md when I tried to execute the first line INSERT INTO private.keys (key, value) values ('SENDGRID_API_KEY', 'aaaaaaaaaa'); in SQL editor (with my API key) in Supabase I've got this error: "Failed to run sql query: relation "private.keys" does not exist"

Here's a repo where I use the http extension extensively: https://github.com/burggraf/supabase-mailer

I was excited to find the supabase-mailer project, but unfortunately it seems that only the Mailgun provider is fully supported and working. Mailgun only has a 30 day trial, which didn't work for my needs.

You can't call the http function like that. You need to use a SELECT statement. See https://github.com/burggraf/supabase-mailer/blob/main/02A_send_email_mailgun.sql for an example: SELECT content INTO retval FROM http (('POST', ....etc

I'm not 100% sure you could do this with PostgreSQL functions, but you probably can. Since we have http access from these functions, I've written interfaces to some of the transactional email apis here: https://github.com/burggraf/supabase-mailer . (It's probably even easier if you use straight SMTP mailers.)

Not sure what you mean. I have a couple open-source repos on github that show you how you can send emails or text messages from a Postgres function using third-party providers. I also have a repo that shows how you could roll your own auth using functions. Assigning permissions and roles is definitely something you can do in functions -- that's standard postgres stuff....

I also wrote this library, which makes things even more node/deno like: https://github.com/burggraf/supascript

You can also check out my SupaScript extension here, which may give you access to other node libraries you may need: https://github.com/burggraf/SupaScript

And I write a majority of my functions using Javascript and even have access to a lot of npm libraries. (I wrote https://github.com/burggraf/SupaScript for this purpose).

You should also look at my SupaScript repo on github. This is a wrapper on PLV8 that lets you write functions in Javascript with NodeJS and Deno-like functionality. It also makes it MUCH easier to work with JSON data and make HTTP calls to API providers. If you're comfortable with NodeJS, you'll find it pretty easy to write Postgres functions with this.
