Joshen Lim 71d58cba7f Joshenlim/fe 4401 re sql editor silently points to the primary instead of (#50513)
## Context

Fixes the following 2 issues with the database selection in the SQL
Editor
- An errant `useEffect` was resetting the `selectedDatabaseId` back to
the primary every time the `databases` list from `useReadReplicasQuery`
changed reference (not just on first load).
- `QuerySourceMenu` kept showing "Read Replica" even after selection had
reverted
- Was using local storage value as the `identifier` for
`DatabaseParametersSubMenu`, when it should use the valtio store as the
source of truth

## Summary by CodeRabbit

- **Improvements**
- The SQL Editor now remembers the last selected database between
sessions.
- Your saved database selection is restored when available; otherwise,
the project’s primary database is selected automatically.
- Query source settings now stay synchronized with the database
currently selected in the SQL Editor.

- **Bug Fixes**
- Background database refreshes no longer unexpectedly reset your
selected read replica to the primary database.
- Database selection now waits for saved preferences to load, preventing
a brief incorrect selection.

Supabase Studio

A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:

What's included

Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.

As such, the features exposed on Studio for existing deployments are limited to those which manage your database:

  • Table & SQL editors
    • Saved queries are unavailable
  • Database management
    • Policies, roles, extensions, replication
  • API documentation

Managing Project Settings

Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.

How to contribute?

  • Branch from master and name your branches with the following structure
    • {type}/{branch_name}
      • Type: chore | fix | feature
      • The branch name is arbitrary — just make sure it summarizes the work.
  • When you send a PR to master, it will automatically tag members of the frontend team for review.
  • Review the main contributing guide to help test your feature before sending a PR.
  • The Dashboard is under active development. You should run git pull frequently to make sure you're up to date.

Developer Quickstart

Note

Supabase internal use: To develop on Studio locally with the backend services, see the instructions in the internal infrastructure repo.

# You'll need to be on Node v22
# in /studio

## For external contributors
pnpm install # install dependencies
pnpm run dev # start dev server

## For internal contributors
## First clone the private supabase/platform repo and follow instructions for setting up mise
mise studio  # Run from supabase/platform alongside `mise infra`

## For all
pnpm run test # run tests
pnpm run test -- --watch # run tests in watch mode

Running within a self-hosted environment

Follow the self-hosting guide to get started.

cd ..
cd docker
docker compose -f docker-compose.yml -f ./dev/docker-compose.dev.yml up

Once you've got that set up, update .env in the studio folder with the corresponding values.

POSTGRES_PASSWORD=
SUPABASE_ANON_KEY=
SUPABASE_SERVICE_KEY=

Then run the following commands to install dependencies and start the dashboard.

npm install
npm run dev

If you would like to configure different defaults for "Default Organization" and "Default Project", you will need to update the .env in the studio folder with the corresponding values.

DEFAULT_ORGANIZATION_NAME=
DEFAULT_PROJECT_NAME=
