How to use JSON Path
JSONPath is a query language used to extract data from JSON documents. It has gained relevance with more tools and standards relying on it, such as OpenAPI. JSONPath allows filtering, querying, and traversing through complex JSON structures, making it useful for tasks like writing advanced linting rules or overlays in API documentation. The syntax of JSONPath includes elements like $ (root node identifier), @ (current node identifier), [<selectors>] (child segment), .name (shorthand for ['name']), and ?<logical-expr> (filter selector). By combining these elements, users can create powerful queries to manipulate JSON data. JSONPath is also used in tools like Bump.sh CLI for tasks such as updating or removing specific parts of an OpenAPI document.
