Claude 8e335582fb feat(storage): let a blocked drag start, then explain on drop
Refusing to start the drag while a move was running left nothing to read:
pressing a row just did nothing, with no signal about why.

A drag that can't be dropped now behaves like any other drag — it starts,
follows the pointer, and carries the whole selection. What changes is the
feedback: no drop target highlights, rows and columns show a not-allowed
cursor, the drag preview carries a short reason, and releasing lands in
moveItems, which says what to do about it.

Both blocking reasons run through the same path, so the over-cap case
gets this treatment too instead of only the running-move case:

  getDropBlockedReason -> 'Move in progress' | 'Max 25 items' | undefined

It's computed once in the provider and read from the dnd context, so rows,
columns, and the preview can't disagree about whether a drop is possible.

The bulk Move button and its shortcut stay disabled with a tooltip. A
disabled control with an explanation is already legible, and it's the
pattern Studio uses elsewhere — it was only the silent drag that wasn't.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Envoy is a cloud-native, high-performance edge and service proxy.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
