* Polderfest 2027 — seed script
|
|
* ----------------------------------------------------------
|
|
* Genereert 500 fictieve bands en zet ze in je Supabase `bands` tabel.
|
|
* Run:
|
|
* 1. Zorg dat `bands` tabel bestaat (zie schema.sql)
|
|
* 2. Vul .env.local met:
|
|
* SUPABASE_URL=https://<project>.supabase.co
|
|
* SUPABASE_SERVICE_ROLE_KEY=<service role key>
|
|
* 3. npm i @supabase/supabase-js dotenv tsx --save-dev
|
|
* 4. npx tsx seed-polderfest.ts
|
|
*
|
|
* Service role key is bewust nodig — alleen voor lokaal seeden.
|
|
* NIET committen, NIET in client gebruiken.
