Sanity is a real-time content infrastructure with a scalable, hosted backend featuring a Graph Oriented Query Language (GROQ), asset pipelines and fast edge caches
React hooks and UI for reading and managing secrets in a Sanity Studio. This is a good pattern for keeping configuration secret. Instead of using environment variables which would be bundled with the Studio source (it is an SPA), we store secret information in a document in the dataset. This document will not be readable to externals even in a public dataset. With custom access controls you can also specify which users can read the configuration in your Studio.
