Demonstration API definition

Swagger 2 Petstore is sufficient.

Configuration (browser query string, constructor, config.yaml)

Default.

Current Behavior

As an example, GET /pet/findByStatus in the Petstore currently returns 1.8MB of JSON when all statuses are selected. This is a pretty big chunk of data, but Swagger-UI insists on rendering the entire body, which is neither performant or useful. The main thread of the application is locked for upwards of 20 seconds on my machine.

Possible Solution

Truncate or refuse to display large textual response bodies.

Context

GET /pet/findByStatus is my favorite operation to use when testing UI enums, so this is something that impedes me pretty regularly.

Ran into this recently too. Looks like you can turn it off via config. For me, this worked:

SwaggerUI({
        syntaxHighlight: {
          activated: false,
          theme: "agate"
        },
        //url: path,
        ....
      });

1. Years. Later. Still the same problem and no flag available to disable pretty print… 😦
