How to stop Heroku from trying to install Husky

I have a Node app (React) on Heroku and the deploy and build was previous working fine, I have now added Husky, Lint-staged, Craco and WDYR to a new branch which works locally.
Upon trying to deploy and build this branch on Heroku, I am finding that the build fails due to Heroku trying to install Husky despite me not asking it to and it being a development tool. It makes sense that Heroku cannot find Husky as it is a dev dependency.
From what I can see Heroku is running the prepare script from the client package.json, which it shouldn't be.
How can I stop Heroku from trying to install Husky?
Here are my package.json files (haven't included server package.json as I'm not sure it's relevant).

Here is a screenshot of the error:

Here is the best solution:
run npm ci --only=production --ignore-scripts
https://github.com/typicode/husky/issues/920
Following is from Heroku support ticket (I did not check this info):
To cover the --only=production flag, you can set the environment
variable NPM_CONFIG_PRODUCTION=true
https://devcenter.heroku.com/articles/nodejs-support#only-installing-dependencies
While it isn’t possible to add the --ignore-scripts flag to the
install command directly, it can be set via npm config with npm config
set ignore-scripts true and this will achieve the same thing during
installation.
The above command could be included using heroku-specific-build steps.
e.g.;
"scripts": {
"heroku-prebuild": "npm config set ignore-scripts true",
...
}
Alternative solution (but it has a drawback):
You can direct Heroku to only install dependencies by setting environment variables NPM_CONFIG_PRODUCTION=true or YARN_PRODUCTION=true
See https://devcenter.heroku.com/articles/nodejs-support#only-installing-dependencies
This way you won't install devDependencies, assuming husky is in devDependencies (why would it not be?) meaning husky will never install.
The drawback is it won't install with any other devDependencies and i.e. I have there webpack which is required to run on build step. I don't want to move it from devDependencies to dependencies so I cant use this solution.

How to fix issue where I'm getting thousands of errors from prettier in my React App?

I am encountering this issue where prettier is giving me in excess of 1000 errors. I'm not sure what is causing it however here is how I got to this issue. I followed TraversyMedias guide on youtube to install eslint and prettier with the airbnb template. It was working great. I programmed for close to a day with it. Then after I started switching a component I had from React hooks state to Redux state I got an error saying that a file couldn't be found. After I fixed the issue it still was coming up with this error. I restarted my dev server and got a different error entirely it was an issue with the version of eslint i had. I can't remember the specific error but it was something along these lines "The react-scripts package provided by Create React App requires a dependency: "eslint": "^7.11.0". " After I got that error I followed these steps
To fix the dependency tree, try following the steps below in the exact order:
Delete package-lock.json (not package.json!) and/or yarn.lock in your project folder.
Delete node_modules in your project folder.
Remove "eslint" from dependencies and/or devDependencies in the package.json file in your project folder.
Run npm install or yarn, depending on the package manager you use.
after I did that I encountered the error I am asking the question about.
some useful information My project structure is a top level project folder. it contains both my server and client folder and all three have their own package.json.
I look on this forum for someone with an error similar to mine and couldn't find any.
I googled many different worded questions about this issue and can't find anything on it.
I uninstalled prettier to see if it would go away. it didn't
here is what my package.json looks like in this order root folder client folder and server folder

Any help you guys could give me would be fantastic. And please pardon me if I asked this question wrong. It is my first time asking any question on a programming forum.

The error I was getting had something to do with how eslint was set up or how prettier was set up. I deleted everything that was related to that and now the project is working.

In a React 17 project I wanted to run, there were 2 .ignore files: .prettierignore and .eslintignore.
I added the src folder to these files and with that the errors disappeared.
This way you don't have to remove everything, and you can leave it to address it at a later time if you want.

from my eyes it seems to be problem with node-sass but I am not sure
Is there some thing I should do to fix that?

This problem can occur with native (i.e. compiled, non-Javascript) npm modules when you install Node using the Ubuntu software manager.
For example, Ubuntu 20.04 comes with a system version of glibc 2.31.
However when you install the current latest version of Node via the Ubuntu software manager, it comes as a Snap package which also installs dependency package core containing glibc 2.23, and it is this one that your system version of Node will use (hence the path beginning /snap/core/current/lib/ in the error message, instead of just /lib/). Unfortunately, when you install native modules and the bindings are either downloaded or compiled locally for your system, the versions of the dependencies that the Snap package version of Node will be using are not taken into account, hence the error.
You should find that if you download the same version of Node from nodejs.org and run that binary instead of the system version from the Snap package then you won't get the error.
The solution is therefore not to install Node from the Ubuntu software manager. Use nvm or manual install instead.

After deploying on GH pages the app doesn't work

I have such problem, after deploying my React app on GitHub it works only in my PC. When I open link where is my App have to be deployed using my PC or LapTop link - it works, but when I tried to open it with phone or send this link to my friend - there is empty page (with my background). So how to solve this problem?
There is my repository link

}

The problem is this line:
const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ in store.jsx
window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ is only available if you have Redux Web Tools installed on your browser. Your app didn't run for me locally either. However, once I installed the extension, it ran correctly both locally as well as on your deployed site.
This thread might help find the right way to use composeEnhancers in production. Ideally, in production, you shouldn't be depending on properties populated by the dev tool plugin for debugging but you should be using compose directly from redux.

React - Infinite looping xhr sockjs-node

I have never hosted a website using react.js (Create-React-App).
I have made this website online but I have not turned on the API.
i don't know why i get auto looping xhr socketjs-nodes like this:
and even though I only entered 1 project using React.js and got Physical Memory Usage almost 600MB is this all because of this xhr?

This is most likely webpack-dev-server's requests (maybe hot module replacement feature is enabled, not sure, maybe something else). Create-React-App uses it under the hood in development mode if I'm not mistaken (sorry, didn't use it a lot). So I believe it's fine, not sure if those 600MB of memory usage are related to it though.
My personal sidenote: I always found those bootstrap tools like Create-React-Apps a bad thing for beginners because it's hard to understand what's happening under the hood. My advice - either dig into what create-react-app uses under the hood to understand the stack better or just create your react app from scratch, it's not hard at all and IMO better. You'll probably just need node + webpack + react

I had a similar problem and in my case the error was in my code where there was a loop between two resources, in one a resource "B" was requested from a resource "A", and in "B" it requested "A" to obtain an element of it.
https://stackoverflow.com/a/68202789/2493852

We faced a similar issue with a production React.js app just today. When accessing the production React app, we were still seeing these errors, even though a production build is deployed.
Later only we got to know that some development artifacts slid into build artifacts during the build process. This had happened because the app was being built for production while a development server was running. While the app was being built, it had also taken the temporary development artifacts generated by the webpack-dev-server into account and had included those in the production bundle.
To make sure this doesn't happen again, we made sure not to production build React apps while the development server/s is/are running for the same app.
