Supabase

A Supabase client for Elixir.

With this library you can work with Supabase. At the moment there's functionality for

auth
database/postgrest
storage

auth and database are implemented in different libraries. gotrue-elixir for auth and postgrest-ex for database.

supabase-elixir handles the correct initializtion from a common config.

Installation

def deps do
  [
    {:supabase, "~> 0.2.0"}
  ]
end

Configuration

You can configure your Supabase project url and api anon key so that supabase-elixir can handle the correct initialization of the different clients:

config :supabase,
  base_url: System.get_env("SUPABASE_URL"),
  api_key: System.get_env("SUPABASE_KEY")

Auth / GoTrue

Uses gotrue-elixir

Supabase.auth()
|> GoTrue.settings()

Database / Postgrest

Uses postgrest-ex:

import Supabase
import Postgrestex

Supabase.rest()
|> from("profiles")
|> eq("Username", "Patrick")
|> json()
%{
  body: [
    %{
      "avatar_url" => "avatar.jpeg",
      "id" => "blabla7d-411d-4ead-83d0-452343b",
      "updated_at" => "2021-05-02T21:05:37.258616+00:00",
      "username" => "Patrick",
      "website" => "https://patrick-muehlbauer.com"
    }
  ],
  status: 200
}

# Or when in a user context with available JWT
Supabase.rest(session.access_token)

# To use another schema than 'public'
Supabase.rest(schema: 'other_schema')

Not depending on Application config

Supabase.init("https://my-project.supabase.co", "my-api-key")

Storage

The API tries to reflect the one of the offical JS client.

{:ok, object} =
  Supabase.storage()
  |> Supabase.Storage.from("avatars")
  |> Supabase.Storage.download("public/avatar1.png")

# with user context
{:ok, object} =
  Supabase.storage(user.access_token)
  |> Supabase.Storage.from("avatars")
  |> Supabase.Storage.download("public/avatar1.png")

Testing

The tests require a Supabase project (the url and api key) where Row Level Security is disabled for both, BUCKET and OBJECT.

export SUPABASE_TEST_URL="https://*********.supabase.co"
export SUPABASE_TEST_KEY="***"

mix test

# or with coverage
mix coveralls
