Saxon FletcherandClaude Opus 5 7880c2f079 fix(studio): explorer chat and notebook layout refinements (#50453)
Five layout fixes across Explorer chat, notebooks, and the sidebar.

### Chat

- **Conversation fade overlapped the scrollbar.** The top and bottom
gradients are positioned against the conversation's padding box, which
includes the scroll container's scrollbar gutter, so `inset-x-0` painted
them over the scrollbar. They now stop at the conversation's content
gutter, which `Conversation` owns for both the content and the fades.
- **Composer background bled past the input's radius.** The form paints
the surface behind the textarea but had no radius of its own, so its
square corners showed outside the `rounded-lg` input. It now shares the
radius.
- **Message parts used two different widths.** Wide parts come down to
`max-w-3xl` so every part shares a column, matching `AssistantQueryCell`
and `AssistantNotebookPreview`. `isWide` / `isWideMessagePart` stay in
place with both widths equal, so a part can diverge again later without
rebuilding the mechanism.

### Notebooks

- **Cell controls sat at the container edge.** Each cell centred itself
at its own max width while the grip and add-cell button stayed at the
far left of the full-width row, leaving a large gap. `SortableSection`
takes a `sectionWidth` and carries its control gutter twice — once as
the controls, once as padding on the other side — so the section stays
centred with its controls immediately beside it. Cell widths are
unchanged (prose `48rem`, query `72rem`); set them equal and the two
cell types' controls line up on their own.

The controls stay in flow rather than floating in an outside gutter, so
on a viewport narrower than the cap the row just fills the space instead
of clipping the controls into the padding.

### Sidebar

- **Search icon didn't line up with the menu row icons.** The row box
already sits flush with the search input's box, so rows moved from
`pl-3` to `pl-2` to put their icons on the same 8px offset the search
icon uses. Spacing between the input and the list now matches the 12px
side padding.

### Testing

`pnpm --filter studio run typecheck`, Prettier, and 378 tests across
`Explorer`, `ProjectHome`, `AIAssistantPanel`, and `ExplorerLayout`
pass. ESLint warning counts are unchanged from master.

These were reasoned from layout rather than checked in a browser, so
they're worth a look on a preview before merge.

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=
