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.
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.
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.

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.
I have a custom Express project with a small React front-end builded with gulp.
What I would like to do is to add a create-react-app as second front-end like this one in my project, so I:
created a src/ folder in the root of the project
pasted the src/ form the create-react-app in my project src/
added react-scripts and all the create-react-app dependencies in my package.json
installed all the new dependencies
added "build": "react-scripts build", to my package.json scripts
I would like to build the create-react-app in the default folder /build and respond to all the request that doesn't match my API routes with the index of the builded create-react-app using this code in the routes bottom:
app.get('*', (req, res)=>{
res.sendFile(path.join(__dirname, '..','build','index.html'));
})
But running npm run build I get:
> node-js-scaffolder#0.0.1 build /Users/matt/dev/my-api
> react-scripts build
Could not find a required file.
Name: index.html
Searched in: /Users/matt/dev/my-api/public
I actually have a public/ folder where gulp saves my builded front end together with some images, but react-scripts should look in the src/ folder for the entry point of the create-react-app.

What am I doing wrong?
I've made a new repository but I still want to serve the create-react-app with express so I've followed this tutorial and created a /client folder in my project and put there all the create-react-app files and folders together with its package.json.
The scripts I use to deploy or lunch in dev mode are the following:
"client": "cd client && yarn start",
"server": "nodemon server.js",
"dev": "concurrently --kill-others-on-fail \"yarn server\" \"yarn client\"",
"build": "yarn && cd client && yarn && yarn build && cd ../",
"deploy": "git pull origin master && yarn build && pm2 restart server.js || pm2 start server.js"
I'd like to know which are the cons of this approach if someone has any experience.
First, eject your create-react-app project like this :
npm run eject or yarn eject
Second, you can configure index.html and public folder path from: [react-project-dir]/config/paths.js
In your case i assume eject command will create a folder in root directory of your project so you can find it in: [project-dir]/config/paths.js
You can change these parameters:
...
appPublic: resolveApp('public'),
appHtml: resolveApp('public/index.html'),
like this:
appPublic: resolveApp('public_react'),
appHtml: resolveApp('public_react/index.html'),
Im developing a web app using React JS(Using Create React App) which will run on Stellar and Im using the official JS Stellar SDK. However, after integrating the Stellar SDK, I get a Babel error due to the Stellar SDK. Has anyone faced this issue before? The error is as follows :
./node_modules/js-xdr/lib/opaque.js
Module not found: Can't resolve 'babel-runtime/helpers/interop-
