express-swagger-explorer

Install

npm i --save express-swagger-explorer

Usage

const app = request('express')();
const swaggerUI = require('express-swagger-explorer')();
app.use('/api-documentation', swaggerUI);
app.listen(8080)

Now you have a nice Swagger UI API explorer:

http://localhost:8080/api-documentation

Note: Swagger UI expects a Swagger 2.0 swagger.json file to exist relative to the Swagger UI folder.
