// Sign up
let signUp = async () => {
  let response = await supabase->auth->signUp({
    "email": "[email protected]",
    "password": "password123"
  })
  
  switch response.error->Js.Nullable.toOption {
  | Some(error) => Js.log(error.message)
  | None => Js.log("Success!")
  }
}

// Sign in
let signIn = async () => {
  let response = await supabase->auth->signInWithPassword({
    "email": "[email protected]",
    "password": "password123"
  })
  // Handle response...
}

// OAuth sign in
let signInWithGoogle = () => {
  supabase->auth->signInWithOAuth({"provider": "google"})
}

Database Queries

// Select all
let getUsers = async () => {
  let response = await supabase
    ->fromTable("users")
    ->select("*")
    ->execute
    
  response.data
}

// Filter
let getActiveUsers = async () => {
  let response = await supabase
    ->fromTable("users")
    ->select("*")
    ->eq("active", true)
    ->order("created_at", {"ascending": false})
    ->limit(10)
    ->execute
    
  response.data
}

// Insert
let createUser = async (user) => {
  let response = await supabase
    ->fromTable("users")
    ->insert(user)
    ->execute
}

Storage

// Upload file
let uploadFile = async (file, path) => {
  let response = await supabase
    ->storage
    ->from("avatars")
    ->upload(path, file, {"upsert": Some(true)})
}
