A VSCode extension for using the JSON Schema Language Server.

VSCode's built-in "JSON Language Features" extension includes JSON Schema functionality. That means you could end up getting the same messages twice (once from the built-in extension and once from this extension) or you might get incorrect or confusing messaging. For example, JSON Language Features will warn you against using 2020-12 because it doesn't support dynamic references, but this extension fully supports 2020-12 and you are encouraged to use it.

If you wish, you can disable the built-in extension. In the "Extensions" tool, search for @builtin json language features to find the extension. Click the "Disable" button to disable it.

If you do choose to disable the built-in extension, keep in mind that this extension is not yet a complete replacement and you may end up losing some functionality you're used to.

Contributions are welcome and encouraged! If you have a feature/bug/improvement you want to work on, it's usually best to open an issue to discuss the issue before starting work.

This is the launcher I use to launch the extension for development. Yours may vary slightly depending on your environment.
