pg_graphql VS Hasura

Hi, I'm the author of Supabase GraphQL (pg_graphql)

One of the restrictions of composite types is that they can not contain an instance of themselves. So unfortunately, this is not currently possible.

I had this issue when trying to implement an AST type for pg_graphql[1] back when it was written in SQL [2]. In the end we used a JSON type which was much less constrained. That might be solvable using pg_jsonschema [3] if you really wanted to have a good time though

It’s something that’ll come in future, but nothing available yet: https://github.com/supabase/pg_graphql/issues/17

But... If you're looking for Graphql/Postgres, maybe look at https://github.com/supabase/pg_graphql which popped onto my radar yesterday, but I have no experience with it.

Check out some of the generated queries this extension [1] pumps out and you might have an answer.

hey HN, supabase ceo here. I'm really excited about this release.

Our GraphQL implementation is built on top of pg_graphql[0], a PostgreSQL extension we open-sourced a few months ago. The implementation works with a lot of native PG functionality (like Row Level Security). You can also do a some neat things with PG GRANTS, enabling/disabling access to different tables/columns to effectively serve a different GraphQL API depending who is "logged in".

On Supabase, the extension is served via PostgREST[1] using the public PostgreSQL function exposed by pg_graphql. PostgREST exposes PG functions as RPC routes (in our case we also map /rest/v1/rpc/graphql => /graphql/v1)

I'll ping the main dev (@oli_rice) and make sure he is here to answer any technical questions. This is just one of the exciting features we're launching this week. Stay tuned for one of our most-requested features later this week.

> 2. ORMs do not hide SQL nastiness.

This is certainly true!

I mean: ORMs are now well known to "make the easy queries slightly more easy, while making intermediate queries really hard and complex queries impossible".

I think the are of ORMs is over. It simply did not deliver.

If a book on SQL is --say-- 100 pages, a book on Hibernate is 400 pages. So much to learn just to make the easy queries slightly easier to type? Just not worth it.

I prefer jooq any day over ORMs. And dont get me started over what tools like Hasuna have to offer.

There are also some languages (forgot the names) that are SQL-done-right. Select in the back, more type safe, more logic, more in the same steps as the query gets executed. These need to be adopted by PG and MySQL and we're good to go. (IMHO)

Another strategy is to model access control declaratively and enforce it in the application layer. ZenStack (built above Prisma ORM) and Hasura are good examples of this approach. The following code shows how access policies are defined with ZenStack and how a secured CRUD API can be derived automatically.

Today, this ecosystem is going strong with new providers like Hasura, AppWrite and Supabase powering millions of projects. There are a few reasons people choose this style of hosting, especially if they are more comfortable with frontend development. BaaS lets them set up a database in a secure way, expose some business logic on top of the data, and connect via a dev-friendly SDK from their app or website code to save data easily. These modern tools build a blend of managed database with curated plugins such as authentication, great admin dashboards, and function as a service type capability - all in one package, and often offered as a integrated hosted service.

Hi! If you’ve ever thought about something like using GraphQL for something like this.. You might like Hasura. (Obligatory I work for Hasura)

We’ve got an OpenAPI import and you can setup cron-jobs or one-off jobs and do things like load in headers from the environment variables to pass through. There isn’t currently an easy journey for chaining multiple calls together without writing any code at all, but you can wrap pretty much any API endpoint via OpenAPI import or a custom action, and you can even make minor edits to things like the API contract format to change aliases/naming.

Our goal is to join all the things, databases and API’s. Most people know us for instant GraphQL API’s that give you CRUD on your database, but we also wrap APIs.

Not sure if something like this would fit your use-case and do check out some of the other things mentioned, but depending what you are trying to do I think Hasura might potentially work.

Nested Mutation - 113 thumbs up, and still open since 2019... another case of not listening to the users?

Hasura is an open-source real-time GraphQL API server with a strong authorization layer on your database. You can subscribe to database events via webhooks. It can combine multiple API servers into one unified graphQL API. Hasura is a great tool to build any CRUD GraphQL API. Hasura does not have any authentication mechanisms; e.g., you need an auth server to handle sign-up and sign-in.
