How to deploy React app (create-react-app) to Back4App? - reactjs

I've created an React app with create-react-app and I want to deploy it to Back4App.
The problem is I want to deploy the build folder and not the public folder (which I understand is the default for Back4App / ParsePlatform).
So far, I haven't found any way to config deploy to use anything other than the public folder.
Any solution / workaround to this?

If you are using B4A CLI, one of the easiest ways to deploy a create-react-app is, firstly, changing the build script into your package.json as below snippet:
...
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build && cp -r build/* {{PATH-TO-YOUR-B4A-APP}}/public",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
...
As you can see, you just need to move all content inside create-react-app build folder to the public folder of your cloud code. After that, move to your app path and run b4a deploy.
Also, you could add a step to clear all public folder content before move the new stuff, but be careful with this step.
Otherwise, you could access the Back4app Parse-Dashboard into the Cloud Code Functions and deploy all the build stuff in public folder using the browser interface.
This is a live demo of a create-react-app deployed in Back4App.

How to rename 'index.js' file in React File structure to something else?

In the React file structure under components there is index.js file that runs the main character when running the project. Is there anyway to rename this file to any name I want? I am using PM2 server manager and there is no way for me to keep track which server is which when running multiple index.js files. So the only option I got is to rename this index.js to something specific to each project.
I have tried changing the package.json file's start script as below but nothing worked out only gave errors.
"scripts": {
"start": "test.js react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
}
Appreciate all your help!
You can't change the name of the file used by create-react-path.
You'll have to either eject to use custom webpack config by running
npm run eject
But it's a one-way operation (see documentation)
Or you can use Vite instead of create-react-app to bundle your project.
Vite is more configurable than create-react-app, you define in the index.html the name of your js file. So you can put any name you want.
Maybe even this example could help you:

Launch mock server on vercel

I have a React project and installed mock server with json-server node module.
(For your note: Here is the json-server documentation for better understanding. [link]1)
I can start mock server with npm script [npm run mock].
After run the script, mock server start working with this link: localhost:3000.
This react project is working well on local environment.
Now I am going to deploy react project on vercel.
But I have no idea for start mock server on vercel.
How can I start mock server on vercel?
Here is the scripts of package.json file for the application.
{
...
"scripts": {
"start": "PORT=3001 react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject",
"mock": "json-server --watch src/mock/db.json",
"preinstall": "npm install --package-lock-only --ignore-scripts && npx npm-force-resolutions"
}
...
}
Please ask me more information what you want to check.
I had a similar issue and this article save my life.
https://shadowsmith.com/how-to-deploy-an-express-api-to-vercel
Instead of deploying together with my React project, I deploy JSON Server as a separate mock server.
First of all, you need to create a server.js to run JSON Server as a module.
Reference: https://github.com/typicode/json-server#module
At the end of the file, export server in order for Vercel to turn Express into a serverless function
// Export the Express API
module.exports = server;
Last but not least, create a vercel.json in order to deploy to Vercel.
Here are my scripts for your reference purpose: https://github.com/kitloong/json-server-vercel

React-create-app index.js file doesn't reload automatically

I'm using React version 17.0.1 on windows and I've noticed that the create-react-app hot reload doesn't work. I found some tips online (Development server of create-react-app does not auto refresh for example ) and tried every one of them (my path doesn't include parentheses, it isn't synced to google drive or dropbox, I've tried the watcher refresh and reinstalling the node modules). Nothing worked until I realized that the problem occurs only with the index.js file. If I save any other file (html or components) the browser does reload automatically. I've read that this might be a bug with the newer version of React that was released just days before I started studying this subject.
One thing I should mention is that my npm start script (that was automatically generated) is different than the ones I saw on the other threads (Auto reload react server on update for example), It doesn't says "Webpack" at all and I thought it maybe have something to do with my problem.
From the package.json file:
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
Is there any way around this bug? Is this problem familiar?

How to prevent npm run build from deleting directories in build

I have a SPA react app to host my personal projects. The layout is created with react, but each personal project is a directory with normal index.html, .js, and .css files.
I couldn't figure out how to successfully use <Link> to render the regular .html pages on click, so I'm taking the easy route for now: manually moving each directory into build, then linking to it with .
This works, but every time I rerun npm run build it erases all of my project directories. How can I prevent this behavior? (I'm using create-react-app with defaults).
tl;dr: How to tell npm run build not to delete certain directories inside build.
Build folder should be cleaned up on each build. This is best practice so your project can be build by different developers, having only source code.
To achive your task you should use additional npm script which will be automatically run after build. (You may see all possible stages when scripts can be run here)
postbuild script should copy additional files from some path under src folder to build folder. So on each build you'll have all required files in place
Example
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject",
"postbuild": "copy .\\src\\app.js .\\build\\app.js"
},
Last line will copy app.js from src folder to build folder. The same way you can create script to recreate all required directories after each build.

How to deploy React build folder to Heroku

 I looked around the internet for this and found this medium article using serve. The article directed modifying the packange.json file to this:
"scripts": {
"dev": "react-scripts
"start", "start": "serve -s build",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject",
"heroku-postbuild": "npm run build"
},
Now this works in development. I get console logs saying Content is cached for offline use. And google Lighthouse gives me >90% on progessive web apps. The problem is, when I deploy to Heroku, during build it runs the npm run build specified in the package.json scripts. But on opening the app, I get 21% on performance, and 50% on progressive web apps in firehouse. Also, it says service worker not registered. Which means it is not serving from the build folder. As an extra, I ran npm build myself in development machine and deployed the project TOGETHER with the build folder, but still same result. Now I also came around this other articlesuggesting to use node.js server and change scripts in package.json to this:
start: "node server.js"
I no nothing about node.js, so I decided to consult here for better choices.
EDIT: If a server command is needed, like in the node.js in the second medium article, and in Garesh's php code below - if anyone could help with a similar code in python(django), it'd be nice
Found the answer to this in this comment online:
Before deploying the app go to:
Heroku dashboard > settings > buildpacks > add buildpacks and then add github.com/mars/create-react-app-b...
Or, in command line you can do
heroku buildpacks:set github.com/mars/create-react-app-b...
If you don't do this step, heroku will deploy the development build (which is slow) of your react app instead of the optimized production build.
Build you code with:
npm run build
Now Put this code in the index.php file:
<?php header( 'Location: /index.html' ) ; ?>
Now put this index.php file into your build folder.
Copy this build folder somewhere else.
Now configure your new folder with your heroku app.
then
git push heroku master
