Connect to Supabase

Connect to a Supabase database with the supabase-js library.

Import the createClient function from jsr supabase-js package

import { createClient } from "jsr:@supabase/supabase-js@2";

Create a single supabase client for interacting with your database

const supabase = createClient(
  Deno.env.get("SUPABASE_URL")!,
  Deno.env.get("SUPABASE_KEY")!,
);

Insert data into the countries table

let resource = await supabase
  .from("countries")
  .insert({ code: "JP", name: "Japan" })
  .select();

if (resource.error) {
  console.error(resource.error);
}

console.log(resource.data); // [ { code: "JP", name: "Japan" } ]

Get data from the countries table

resource = await supabase
  .from("countries")
  .select();

if (resource.error) {
  console.error(resource.error);
}

console.log(resource.data); // [ { code: "JP", name: "Japan" }, ... ]
