4f80bb70cd fix(studio): prevent Monaco editor collapse after visiting GraphiQL (#47339)
Fixes a pre-existing bug where visiting **GraphiQL** leaves the **SQL
editor** (and other Monaco editors) collapsed to a ~5px slit with the
background spilling over it, until a full navigation away.

## Root cause

GraphiQL (`@graphiql/react`) and the rest of Studio's editors
(`@monaco-editor/react`) share one global Monaco instance. Visiting
GraphiQL does `import 'graphiql/style.css'`, which injects a **second
copy of Monaco's CSS** globally and persists for the session.

`CodeEditor` hard-codes a `monaco-editor` class onto the
`@monaco-editor/react` **wrapper** div (it's not a real Monaco editor —
Monaco creates its own `.monaco-editor` inside it). That makes the
wrapper subject to global `.monaco-editor` rules. After GraphiQL's CSS
loads, the wrapper flips from `position: relative` to `position:
absolute`, drops out of the flex flow, and collapses to `height: 0`.
Monaco then lays out against a 0-height container → ~5px editor, and the
full-size gutter/background layers spill over the area.

Confirmed by inspecting the same wrapper before vs after a GraphiQL
visit — identical inline styles, but `position` flips `relative` →
`absolute` and height `266px` → `0`.

## Fix

Add `h-full` to the wrapper so it fills its (full-height) section even
when it's `position: absolute`, instead of collapsing to 0. Monaco then
measures the correct height. In the normal `relative` state this is
identical to the existing flex-stretch behavior.

This is the contained fix. The deeper fix is isolating GraphiQL's Monaco
from the shared instance (so it can't inject CSS / mutate global state
affecting other editors) — larger, worth a follow-up.

## To test

- Open the SQL editor (renders fine).
- Go to Integrations → GraphiQL, then back to the SQL editor.
- Editor should be full height and fully visible (previously a ~5px slit
covered by the background).
- Sanity-check other editors that use `CodeEditor` (e.g. RLS policy
editor, function editor) still render at the right height.

## Summary by CodeRabbit

* **Bug Fixes**
* Improved the code editor’s sizing so it keeps its full height during
navigation and no longer collapses to a near-zero display in some cases.

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 contributing checklists 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 v20
# 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=
