Easily resolve type at JSONPath

[andyscott]

Given a JSONPath (or similar structure) and a schema, is there a good way to determine the type ('string', 'object', etc) for a value at that path?

JSONPath store.book[0].title might resolve to 'string' against a schema for a book store record.

Would the best approach be to just navigate the schema structure directly?

Not sure if I understood the question correctly.

If you want traversing object using paths, you can use object-path

Or you can use reactive models from milojs framework - it does much more than just that though.

If you want to determine the required type for the value at a given path based on schema, it is not possible, because the schema can have 'anyOf' or 'not' keyword, for example, that would allow multiple types for a given property. Also schema can be written in such a way that the allowed type(s) for a given property would depend on other properties.

If you only use simple keywords then you can answer this question, but in general case there is no definite answer.

Hello, is there currenty a way to "find possible schemas" given a data path (or json pointer of the data) that resolves all $refs along the way (that were added into the Ajv instance)?

I could not find from the docs, I suspect the answer is still no..

Thanks!
