Server

The server backend is built on top of Supabase, which provides infrastructure for database, file storage, user authentication, serverless functions and more.

Local development requires running a self-managed supabase instance using docker containers. Serverless functions are run using a Deno runtime environment

Prerequisites

• Docker Desktop

Quickstart

Start Server

yarn start:server

This will start various backend services within docker containers

Frontend Config
In order for frontend apps to communicate with the server an anon key created by the server must be populated to local configuration.

This key can be found in the console when the server starts, or by running the script

yarn nx run picsa-server:supabase status

This key should be populated to libs\environments\src\supabase\config.json

Create User

In order to allow communication from unauthenticated users to the database a custom anonymous user should be created from the studio dashboard with credentials:

http://localhost:54323/project/default/auth/users

email: anonymous_user@picsa.app password: anonymous_user@picsa.app

Ensure Auto Confirm is checked

Stop Server

When no longer in use the server can be stopped by either stopping the container running in docker desktop, or by command

yarn nx run picsa-server:supabase stop
