I have already created a swagger.json from an open-source library since my API doesn't support creating one due to HAPI-link and libraries. Now what I do is copy the JSON and load into an online Swagger-editor to verify and view the UI but is there any way by which I can feed the swagger JSON and create a SwaggerUI?
StaffAllow your swagger.json file to be servable as static asset via your HAPI.js server. Let's say your server runs on https://pre-existing-swagger.com/ and your swagger.json file is accesible on https://pre-existing-swagger.com/static/swagger.json. Then create a following HTML file called api.html and again make it servable as static asset via your HAPI.js server. Now when you access https://pre-existing-swagger.com/static/api.html, SwaggerUI will render the swagger.json file.
