Building REST API with Grape
summary
A concise demo of the Grape DSL shows actual routes and handlers, the error helper returns status codes and JSON bodies, and the API uses four versioning strategies (path header vendor accept) plus parameter-based versioning. It demonstrates pagination and partial-response patterns, multiple formats including JSON/JSONP and XML, CORS support, basic/digest/token authentication, logging hooks, and testing helpers, with code examples that build working endpoints rather than abstract advice.
