Navigation and completion
Move between OpenAPI operations and their Spring, NestJS, Express, or AWS Lambda implementations, and complete contract paths in Spring mapping annotations.
Documentation pages
CodeLens
Above each mapped endpoint, a CodeLens names the operation it implements
(“OpenAPI: GET /patients/{patientId}”); click it to open the operation. Above each
operation in the contract, a CodeLens names its implementation (“Implementation:
PatientController.kt”), or shows how many there are and lists them. A CodeLens appears
only where both sides exist; drift is reported by the diagnostics. Turn them off with
stackblender.openApiGuard.codeLens.
Go to Definition
F12, Ctrl+click, and Cmd+click work both ways: from a mapping annotation, an Express route, or a Lambda route registration to its operation, and from an operation to every implementation. The commands OpenAPI Guard: Go to OpenAPI Operation and OpenAPI Guard: Go to Implementation do the same from the editor context menu.
Path completion
Inside the string of a Spring mapping annotation (@GetMapping("…"),
@RequestMapping("…"), and the others), completion offers the contract’s paths:
- On a handler, the operations for that annotation’s HTTP method, relative to the controller’s class-level path. Operations that nothing implements yet come first, marked not implemented.
- On a class-level
@RequestMapping, each resource path, up to its first path variable.
