const { startServerWithSwaggerFile } = require('open-swagger-ui');
// or
import { startServerWithSwaggerFile } from 'open-swagger-ui';

startServerWithSwaggerFile('./path/to/swagger.json', port)
  .then(({ app, port, swagFilePath, server }) => {
    console.log(`app started on port ${port}`);
    // app is the express server underneath
    // you may freely add routes to it like
    // app.use(stuff);
  .catch(err => console.error('something went wrong', err));

The startServerWithSwaggerFile function returns express app, the HTTP server instance, port in which the file is open and the reference swagFilePath.
