No longer able to add custom routes or middlewares

[pirumpi]

The custom routes are not longer working with the latest update

'use strict';

var path = require('path');
var http = require('http');

var oas3Tools = require('oas3-tools');
var serverPort = 8080;

// swaggerRouter configuration
var options = {
    routing: {
        controllers: path.join(__dirname, './controllers')
    },
};

var expressAppConfig = oas3Tools.expressAppConfig(path.join(__dirname, 'api/openapi.yaml'), options);
var app = expressAppConfig.getApp();

/** THIS CUSTOM ROUTE IS NOT LONGER ACCESSIBLE **/
app.get('/foo', (req, res) => { res.send('foo')})

// Initialize the Swagger middleware
http.createServer(app).listen(serverPort, function () {
    console.log('Your server is listening on port %d (http://localhost:%d)', serverPort, serverPort);
    console.log('Swagger-ui is available on http://localhost:%d/docs', serverPort);
});

Big issue, causes CORS middleware to not apply. That means the API will fail, from every client.

This is a significant regression, version 2.0.2 supported middleware, it is an important bug to fix

Some hacky code to get this to work, till the fix is out

Take the middlewares (4) you added and insert it into the 5th position(arbitrary - you can try any position before router, and after express json middlewares)

const stack = app._router.stack;
const lastEntries = stack.splice(app._router.stack.length - 4);  // The number of middle ware you added 4 in this case. 
const firstEntries = stack.splice(0, 5); // Arbitary number 5, adding our middleware after the first 5
app._router.stack = [...firstEntries, ...lastEntries, ...stack];
console.log(app._router.stack);
