So, I've tried running npm i on my React app so that I can work concurrently on both front and back end at the same time. However, it seems to be hanging on the "install":

[email protected] install
cd server && npm i && cd ../client && npm i

Below are the package.json scripts I'm using:

  "scripts": {
    "start": "node server/server.js",
    "dev": "concurrently \"cd server && npm run watch\" \"cd client && npm start\"",
    "install": "cd server && npm i && cd ../client && npm i",
    "build": "cd client && npm run build",
    "seed": "cd server && npm run seed",
    "test": "echo \"Error: no test specified.\" && exit 1",
    "eject": "react-scripts eject"
  },

What am I doing wrong? Any help is greatly appreciated!

You may be running into an infinite loop since you have defined an install script in your package.json. For more details on npm scripts configuration have a look here.

You might also be facing similar issues with some of the other scripts you have defined, e.g. build also calls itself npm run build. You should build the project code as part of the build script. See the CRA source build script for reference: https://github.com/facebook/create-react-app/blob/d960b9e38c062584ff6cfb1a70e1512509a966e7/package.json#L8

Try removing the install script and run the commands manually when you need to install dependencies for your project. The updated scripts:

"scripts": {
    "start": "node server/server.js",
    "dev": "concurrently \"cd server && npm run watch\" \"cd client && npm start",
    "build": "cd client && npm run build",
    "seed": "cd server && npm run seed",
    "test": "echo \"Error: no test specified\" && exit 1",
    "eject": "react-scripts eject"
  },

As a side note/question, why don't you run npm i from the root of the project and then run your build and seed commands?

Only installing dependencies will not build your app, in most cases.
