Swappy.one

Simple & Fun project for Supabase Holiday Hackdays!
Swap your Twitter image based on interest/season temporarily or forever!

? Features

• ? Add badges/frame to your Twitter profile
• ? Share templates with your friends to enjoy this festive season
• ? Only update your profile image
• ? Customize the placement of element yourself

? About The Project

This project is inspired by Facebook’s Temporary Profile Picture, as well as the Twitter Space’s logo when someone is joining a Space. Thus, I’ve created this apps to swap your plain Twitter picture to fit the season/event/anything that you want your follower to notice!

After a certain amount of period (you can configure on the app), it will automatically swap back (hence, Swappy) to your original image. And you can revisit the app when you feel like putting on another badges in the future.

Postgres SQL

1. Store user’s history

   create or replace function public.handle_new_user_image()
   returns trigger as $$
   begin
     insert into public.user_history (user_id, template, new_image_key)
     values (new.id, new.template, new.new_image_key);
     return new;
   end;
   $$ language plpgsql security definer;
   
   create trigger on_new_user_image
     after insert or update of update_on on public.user
     for each row execute procedure public.handle_new_user_image();

2. Invoke Vercel serverless function

   create or replace function change_back_image_vercel_webhook (input_id uuid)
     returns integer
     language plpgsql
     as
     $$
       begin
         return (select
           net.http_post(
               url:='https://swappy.one/api/user/change_back_image',
               body:=(
                 select json_build_object(
                   'id', a.id,
                   'old_image_key', a.old_image_key,
                   'token', a.oauth_token,
                   'secret', a.oauth_token_secret
                   ) as body
                 from (select a.id, a.old_image_key, b.oauth_token , b.oauth_token_secret
                   from public.user a inner join public.user_token b on a.id = b.user_id where a.id = input_id) a
               )::jsonb
           ) as request_id);
       end;
     $$

3. Function to query all the rows that need to change back their image, and loop through each row and call the change_back_image_vercel_webhook

   create or replace function check_date_and_change_back()
     returns table (request_id int)
     language plpgsql
     as
     $$
       declare
         r record;
       begin
         for r in (
           select * from public.user
           where now() > change_back_date and changed_back = false
         ) loop
             request_id := change_back_image_vercel_webhook(r.id);
             return next;
           end loop;
       end;
     $$;

4. CRON job to start the function #3 every hour.

   create extension if not exists pg_cron;
   grant usage on schema cron to postgres;
   grant all privileges on all tables in schema cron to postgres;
   
   select
     cron.schedule(
       'change_back_user_old_image',
       '0 */1 * * *', -- “At minute 0 past every 1th hour.”  https://crontab.guru/#0_*/1_*_*_*
       $$
         select check_date_and_change_back()
       $$
     );
