Swagger Tools Production Build Node js - deployment

Question

We implemented the swagger in our nodeJs application. As of now we are created production build using webpack and remove the controller and services file.
bin/www.js
const YAML = require('yamljs');
const swaggerTools = require('swagger-tools');
const swaggerDoc = YAML.safeLoad('./swagger.yaml');
// swaggerRouter configuration
const swaggerOptions = {
controllers: path.join(__dirname, '../public/javascripts/controllers'),
useStubs: true, // Conditionally turn on stubs (mock mode)
};
// Initialize the Swagger middleware
swaggerTools.initializeMiddleware(swaggerDoc, (middleware) => {
// Interpret Swagger resources and attach metadata to request - must be first in swagger-tools middleware chain
app.use(middleware.swaggerMetadata());
// validate the security using JWT token
app.use(middleware.swaggerSecurity({
Bearer: auth.verifyToken
}));
// Validate Swagger requests
app.use(middleware.swaggerValidator({
validateResponse: true
}));
// Route validated requests to appropriate controller
app.use(middleware.swaggerRouter(swaggerOptions));
// Serve the Swagger documents and Swagger UI
app.use(middleware.swaggerUi());
});
If we did the same in production build and the swagger middleware expecting the same path to resolve. after build we delete the public folder.
Webpack code
const path = require('path');
const nodeExternals = require('webpack-node-externals');
module.exports = {
entry: {
server: './bin/www',
},
output: {
path: path.join(__dirname, 'dist'),
publicPath: '/',
filename: 'server.build.js',
},
target: 'node',
node: {
// Need this when working with express, otherwise the build fails
__dirname: false, // if you don't put this is, __dirname
__filename: false, // and __filename return blank or /
},
externals: [nodeExternals()],
module: {
rules: [
{
// Transpiles ES6-8 into ES5
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
},
},
],
},
};
Pleas help us to create a build using swagger middleware
Thanks in advance

Swagger tools is not a package bundler like webpack. So you will still need to provide it the controller files. Since you are deleting /public from prod then there is no way for swagger tools middleware to get the files it needs. Webpack in this case is basically building a dist from your code which is why it's ok to delete the controller and services.
