wtf is graphql-annotations?

graphql-annotations is a JavaScript library that lets you embed custom metadata, called "annotations," directly into the descriptions of a GraphQL schema. In GraphQL, you can add human-readable descriptions to types and fields (like noting that a field is a "user's email address"). This library lets you piggyback on that same description space to also include machine-readable instructions, so your schema can carry extra configuration alongside its regular documentation. At a high level, you write annotations as special tagged lines inside a description, for example, @db.unique or @db.length: 200. The library provides a function that reads through a description, finds any lines tagged with a namespace you specify (like db), and returns them as a neat JavaScript object. A second function can strip those tags back out, leaving only the plain-text description behind, useful if you're showing the schema in an explorer tool and don't want the raw annotations cluttering the view. Who would use this? Someone building a tool that generates database tables from a GraphQL schema. You could annotate a User type with @db.table: 'users' and its id field with @db.primary, then have your code read those annotations to figure out which database table to create and which column should be the primary key. It's a way to keep your schema as the single source of truth for both your API structure and related configuration, rather than maintaining that config in a separate file. The README doesn't go into detail about edge cases, error handling, or performance considerations. The project is relatively small and focused, doing one specific thing: parsing and stripping annotation tags from GraphQL description strings. It doesn't impose any particular database or framework, it just gives you the parsed annotations, and you decide what to do with them.
