Supabase

Helper functions are located in @/supabase/.... Use the exported classes to GET and SET to access and modify the values in the Supabase database.

Each method returns a { data, error } object, where data is a list/object (depending on the query). If the query is successful, error returns NULL.

For example:

import { paymentDatabase } from "@/supabase/database";

async function payments() {
  const { data, error } = await paymentDatabase.getPaymentDetails(
    "sample-username"
  );
  if (error) console.log(error);
  else {
    console.log(data);
  }
}

If successful, data returns:

[{...}, {...},...]
