1Create a free Supabase project

Go to supabase.com → sign up → "New project". Pick any name/password/region and wait ~1 minute for it to spin up.

2Create the table

In your project, open the SQL Editor → "New query" → paste this in and run it:

create table pieces (
  id text primary key,
  title text not null,
  medium text,
  size text,
  date_created int,
  image_date int,
  status text,
  value numeric,
  sold_to text,
  loan_duration text,
  notes text,
  image_url text,
  created_at timestamptz default now()
);

alter table pieces enable row level security;

create policy "public read" on pieces
  for select using (true);
create policy "public write" on pieces
  for insert with check (true);
create policy "public update" on pieces
  for update using (true);
create policy "public delete" on pieces
  for delete using (true);

3Create a storage bucket for photos

Go to Storage → "New bucket" → name it exactly print-photos → toggle it Public → create.

Then back in the SQL Editor, run:

create policy "public read photos" on storage.objects
  for select using (bucket_id = 'print-photos');
create policy "public upload photos" on storage.objects
  for insert with check (bucket_id = 'print-photos');
create policy "public update photos" on storage.objects
  for update using (bucket_id = 'print-photos');
create policy "public delete photos" on storage.objects
  for delete using (bucket_id = 'print-photos');

4Copy your keys into this file

In your Supabase project, go to Settings → API. Copy the Project URL and the anon public key.

Open this HTML file in a text editor, find the CONFIG section near the top of the <script> tag, and paste your two values in, then save and reopen the file.
