This demo can be used with cloud or local services.

Local Services

The Self Hosting Demo repository contains a Docker Compose Django backend demo which can be used with this client. See instructions for starting the backend locally.

This demo requires that you have the PowerSync Django Backend: Todo List Demo running on your machine. Follow the guide in the README of the PowerSync Django Backend to set it up.

Create a new PowerSync instance, connecting to the database of the Supabase project.

Then deploy the following sync rules:

config:
  edition: 3

streams:
  user_lists:
    queries:
      - SELECT * FROM lists WHERE owner_id = auth.user_id()
      - SELECT todos.* FROM todos JOIN lists ON todos.list_id = lists.id WHERE lists.owner_id = auth.user_id()

Configure The App

Copy the AppConfig.template.ts to a usable file

cp library/django/AppConfig.template.ts library/django/AppConfig.ts
