my-react-app | Template for the React for Designers course | Frontend Utils library

I have a button, this is called game. When this is clicked, routing is triggered and you are redirected to localhost:3000/game. However, I do not want to be redirected to a new page, but to a new React app. This app is in a different folder and was regenerated with npx create-react-app game. Is there an option to go to the new React app with this button click? The React app does not need to be started but only opened.

So when I click the button in my localhost:3000 the React App Game should open with the routing e.g. localhost:4000/game. Later, both React apps run on the same domain, for example, my-react-app.com and my-react-app.com/game

Is there such a thing? If so, how can I create it? Haven't found anything so far.

I am new in react-redux and coding in general and I am trying to learn.

So what I did:

• installing node js
• instaling npm i -g create-react-app
• uninstalling npm uninstall -g create-react-app
• install npx create-react-app my-app-name
• cd my-react-app-name
• npm start

my node version node -v v14.16.0

I am about to deploy a react app. I have an API for my react app. On a react development server, it serves react on port 3000, and my API is on port 4000.

I see two ways of going about this.

One way is to use CORS in development. If we go this route, we'll need to also use CORS in production. We'll have an ENV file which tells the react app which host/port it should make requests to. Our CI pipeline will have 2 docker containers, 2 repos. When we deploy a frontend or a backend change, we'll be able to restart both servers independently. We'll have 1 docker running on mysite.com and the api running on api.mysite.com.

Another approach is to use the proxy in package.json and forward all requests to our backend. i.e. instead of having to make requests to localhost:4000/sign-in we just make requests to /sign-in. With this approach, I think it makes a lot of sense to use a monorepo. We would have

After the latest updates in chrome, the browser is not saving my server cookies. Previously, it was working even it showed a warning about it. But now it is not.

Since my react app is hosted on netlify and my server runs on AWS, it is cross-origin. So, I have changed my cookie settings in express-session with sameSite=None secure options as follows.

I have a an issue trying to get constants our of my .env file in a React app. My app structure is pretty basic:

I have a React app embedded in an iframe using iframe-resizer:

I have a Rails app that uses Webpack to bundle its assets. It doesn't currently use React.

In a separate repository, I have created a React app. This React app basically implements a complex custom UI element. The plan is that I can import this react component into my main application.

So far I have added the git repo to my package.json file and can see that the source code of my react app is being downloaded into the /node_modules folder.

I can get Webpack to bundle the app by adding:

To the React app package.json:

"prepare": "npm run build"

And in my main application webpack.config

I am getting Invalid Host header after installing the node_modules in my project. Then I googled it and found this. But don't where I need to add this line in webpack.config.js.
