I am trying to work with Mysql as a document store using xdevapi, but it is written in JavaScript and I am using TypeScript,so I found mysqlx a type definition for xdevapi and I don't know if it is a good one. Is there any better alternative
I can't really say if it's good or not, but the fact is that the original @mysql/xdevapi package does not include any TypeScript definitions.
You can track the following enhancement request for adding TypeScript support and signal your own interest in it.
