    Project mention: Can't link fresh project - problem with underlying postgrest version not supporting 15. | reddit.com/r/Supabase | 2023-01-29

    I suspect this is the culprit (might be wrong): https://github.com/PostgREST/postgrest/blob/main/src/PostgREST/Config/PgVersion.hs

    Project mention: so people are making these | reddit.com/r/ProgrammerHumor | 2022-07-31

    I also looked into Snap (http://snapframework.com/) and Yesod (https://www.yesodweb.com/) for Haskell. I didn't really get anywhere with those though because I had build issues with dependencies and was in a bit of a hurry so I put them off for later.

  • servant

    Main repository for the servant libraries — DSL for describing, serving, querying, mocking, documenting web applications and more!

    Project mention: Question: Servant with NamedRoutes and Swagger | reddit.com/r/haskell | 2022-11-25

    Here's the current commit I'm working with: https://github.com/scotty-web/scotty/commit/3ed8586c046b46dc42740e8ac2e7fe712e84191d

    Project mention: Recommendation for simple static sure generator based on Markdown | reddit.com/r/software | 2022-11-12

    Have you considered neuron or it's successor emanote?

  • aeson

    A fast Haskell JSON library

    Project mention: Haskell adoption is higher than I expected, what can we do to get it to top 10 languages. | reddit.com/r/haskell | 2022-10-24

    Don't get me wrong, we figured it all out, and currently we use Aeson fork as we needed this: https://github.com/haskell/aeson/pull/926, as the default behaviour didn't work with Swift, and I wasn't sure if it's worth spending any time completing it...

  • postgres-websockets

    PostgreSQL + Websockets

    Project mention: PostgREST – Serve a RESTful API from Any Postgres Database | news.ycombinator.com | 2022-12-29

    At work, we've finally replaced a large part of a custom (mostly-)web backend with PostgREST recently, and that's quite a relief: considerably less code to maintain in that project now, and that was a rather awkward code. Something akin to PostgREST's "Embedding with Top-level Filtering" [1] had to be provided for all the tables, with OpenAPI schema and a typed API (Haskell + Servant); I avoided manually writing it all down, but at the cost of poking framework internals, and maintainability suffered. It was particularly annoying that the code doesn't really do anything useful, except for standing between a database and an HTTP client, and simply mimics the database anyway. Whenever a change had to be introduced, it was introduced into the database, the backend, and the frontend simultaneously, so it wasn't even useful for some kind of compatibility.

    Now PostgREST handles all that, and only a few less trivial endpoints are handled by a custom backend (including streaming, which I'm considering replacing with postgrest-websocket [2] at some point).

    During the switch to PostgREST, the encountered minor issues were those with inherited tables (had to set a bunch of computed/virtual columns [3] in order to "embed" those), and with a bug on filtering using such relations (turned out it was an already-fixed regression [4], so an update helped). Also a couple of helper stored procedures (to use via /rpc/) for updates in multiple tables at once (many-to-many relationships, to edit entities along with their relationships, using fewer requests) were added (though the old custom backend didn't have that), the security policies were set from the beginning, the frontend was rewritten (which allowed to finally switch without adding more work), so it was only left to cleanup the backend.

    Not using views, since as mentioned above, database changes usually correspond to frontend changes, and the API doesn't have to be that stable yet.

    Happy with it so far.

  • three-layer

    :three: :cake: Architecture of the Haskell web applications

    Project mention: My Module Structure Does Not Feel Haskell-like | reddit.com/r/haskell | 2022-12-13

    I’m working on this pet project for a time now. Initially based on the three-layer repository, it’s now modelled after the Clean Architecture. In my understanding, it’s an OOP variation of the functional “Functional Core, Imperative Shell” approach. As most examples for Clean Architecture are written in C#, my module structure also looks more like a typical C# than Haskell one to me.

  • nixpkgs-update

    Updating nixpkgs packages since 2018

    Project mention: Chrome technically unusable on NixOS | reddit.com/r/NixOS | 2022-04-15
