Thank you so VERY much. I really appreciate your time and knowledge. Cheers. Amit Chambial

Amit Chambial Thanks a lot for answering my questions. Can you add in your answer? I have added a couple of questions more in my previous reply.

router.get( "/*" , function ( req, res, next ) { res.render( "index" , { title: "My App" }) }) What is this code block doing? Is it rendering the index.ejs file? One more thing, how is /* will be handled by react routers? Also could you clarify my doubts on node environment? In package.json , I have this: "scripts" : { "start" : "NODE_ENV=development nodemon ./bin/www" , "webpack" : "webpack-dev-server --config ./webpack.config.js --mode development" }, In app.js : if (process.env.NODE_ENV === "development" ) { const webpack = require ( "webpack" ) const webpackConfig = require ( "./webpack.config" ) const compiler = webpack(webpackConfig) app.use( require ( "webpack-dev-middleware" )(compiler, { noInfo: true , publicPath: webpackConfig.output.publicPath, }) ) app.use( require ( "webpack-hot-middleware" )(compiler)) } I'm confused on how webpack is working here. I know it generates a bundle but how it's working with env is just that I could not understand. Sorry for asking too many questions.

Amit Chambial okay thanks. One more question, do you have idea about the mern stack. I posted a question today https://hashnode.com/post/i-need-to-know-the-flow-of-this-mern-app-ckbbvixgs028l5ks1b2e3x2zj. If you could help me out, that would be great.

THanks for the post. It's good. I have one question. If I need to check if the app is SSR or CSR, how do I do it?
