const app = express();
 
// create a '/swagger' endpoint ...
swaggerJSDocExpress.setupSwaggerUIFromSourceFiles(
    {
        cwd: '/root/path/to/source/files',
        files: [ '**/*.ts', '**/*.js' ],
    },
 
    // ... and directly register it

    app
);
 
app.listen(8080, () => {
    // should be available via
    // http://localhost:8080/swagger
    // now
});

The following code shows, how to document API (you can put the JSDoc to all locations inside the files, which are handled by setupSwaggerUIFromSourceFiles() function):
