Setup Supabase Policies

Quick tutorial to setup the Supabase policies to manipulate the data.

Create Supabase Project

You need the following things

  • SUPABASE_URL: Database URL.
  • SUPABASE_KEY: It is safe to be used in a browser context.


  • To get these go to Supabase and log in with your account.

  • Click on New Project and fill all the fields.

  • Click on Create New Project.

  • Go to the Settings page in the Dashboard.

  • Click API in the sidebar.

  • Find your API URL and anon key on this page.

  • Now you can Create table and start using it.

    But before you use this there was one issue I had when I was using this it was returning the empty array ([]). It was because of project policies. By default, no-one has access to the data. To fix that you can do the following:

  • Go to Policies.

  • Select your Project.

  • Click on New Policy.

  • You will be presented with two options. You can choose either one. I chose the 1st option:

  • After that, you will have four options as shown in the following image. You can choose according to your need. I only need the read access so I went with 1st option.

  • Click on Use this template.

  • Click on Review.

  • Click on Save Policy

    After that, you will be able to access the data using @supabase/supabase-js. Install it and you just set up your project with Supabase.
