How to serve SwaggerUI without using middleware (app.use)

[Hasankanso]

I'm implementing a controller where I'm only responsible of the get route/function and don't have access to app.

const swaggerUI = require('swagger-ui');

function getSwagger(req, res) {

//swaggerUI.serve?
//swaggerUI.serveFile?

var page = swaggerUI.generateHTML(doc);

return res.send(page);
}

This isn't working with error 404. how do I call serve correctly in the function?

P.S.: this is a pseudo code, because I don't have access to my pc at the moment, but the idea is I don't have access to app.use and app.get, I only can implement inside of the get function.

I don’t think you will be able to do this as the serve is used to serve the assets therefore needs the app.use
