LocalHost to Domain Name using Express in React using nodejs
Question about estimating random symmetric sums modulo p ,I've been searching a lot but I couldn't find anything useful. Or am I not supposed to be using Express? Am I supposed to do something like this:,I was using Express to create a server, developing using localhost:4000. Now that I actually have a domain called let's say https:something.com using AWS amplify, I don't understand what modifications I have to make. Do I have to make Express listen to that url? How do I do that?

Integrate React production into Node.js Project,Run Express and React on same Port,React & Node.js Express Application Overview
Open cmd and create a new React Project as following command:
npx create - react - app react - crud
A React frontend connected to a Node backend is a rock-solid combination for any application you want to build. ,This guide is designed to help you create full-stack projects with React as easily as possible.,When we deploy, both our Node backend and React frontend are going to be served on the same domain (i.e. mycoolapp.herokuapp.com).
To create our Node project, run the following command in your terminal:
npm init - y
Stop the server with Cmd/Ctrl + C and use npm to install Express and Body Parser:,To run both the server and React application at the same time we need to add a couple more things to package.json.,Start by creating a new React app with Create React App. Did you know, you don't have to globally install the create-react-app package to do this? Instead, you can run:
npm init react - app my - new - app cd my - new - app
Using cookies with Secure attribute or SameSite attribute set to None.,Using a custom domain name for the local server instead of localhost.,The above command will generate a certificate and a private key for your domain. You can replace localhost with a domain name of your preference.
Then you can install mkcert using:
choco install mkcert
Now we should create a trusted certificate authority in our system’s root store using the following command.
mkcert - install
Now you can generate an SSL certificate. For that, navigate to the location where you need to generate the SSL certificate and run the following command.
By default requests from any other origins will be restricted by the browser.,There is an HTTP header called origin in each HTTP request. It defines from where the domain request has originated. We can use header information to restrict or allow resources from our web server to protect them.,We're allowed to fetch the information from that application and domain.
Let's start off with a fresh project. We'll make a directory for it, enter it and run
npm init with the default settings:
$ mkdir myapp $ cd myapp $ npm init - y
Testing Node.js applications is out of the scope of this tutorial. However, it's important to implement testing to create robust, production-ready web apps.,You now have the basic structure of a Node.js application.,In this tutorial, you'll learn how to build a simple and clean Node.js server-side rendered application using the Express framework and Pug templates styled with CSS.
Proxy the Node/Express app served on
localhost:8000 as Browsersync only creates a static server for basic HTML/JS/CSS websites. You still need to run the server with
files: ["**/*.css", "**/*.pug", "**/*.js"]
Specify the patterns that file watchers need to ignore. You want to ignore
node_modules to let Browsersync run fast.
Time in milliseconds to delay the reload event following file changes to prevent Nodemon and Browsersync from overlapping, which can cause erratic behavior.
Don't start the Browsersync user interface, a page where you can control the behavior of Browsersync.
Disable a distracting message notifying you that Browsersync is connected to the browser.
Example 2: Suppose we have a domain name instead of localhost as shown below:,Make sure you have installed express module using the following command:npm install express,After installing the express module, you can check your express version in command prompt using the command.npm version express
npm install express
npm version express
npm install express
Server listening on PORT 3000
Server listening on PORT 3000 localhost
Example 2: Suppose we have a domain name instead of localhost as shown below:
Host: "demo.com:3000" console.log(req.hostname);
