Supabase Backend

Database

There is only one table in the database, room, which is defined as follows:

create table
  public.room (
    id uuid not null default gen_random_uuid (),
    created_at timestamp with time zone not null default now(),
    private boolean not null default true,
    online_members uuid[] null,
    creator uuid null,
    room_code text null,
    constraint room_pkey primary key (id)
  ) tablespace pg_default;

Row Level Security (RLS) is not defined to not allow any direct interactions with the database by the clients. Instead, all interactions are done through the Edge Functions.

Edge Functions

All edge functions are defined in the supabase/functions directory and are hosted on Supabase.

Cron Jobs

Install the pg_cron extension on Supabase and run the following SQL query to schedule the cron job to clean up old rooms every three hours:

select cron.schedule(
  'cleanup-of-old-rooms',
  '0 */3 * * *', -- Every three hours
  $$ delete from shortlinks where created_at < now() - interval '3 hours' $$
)
