CodePudding user response：

Your npm install command runs the install in your root package.json which doesn't contain react dependencies. Then the build step goes into ./frontend and tries to use those react script that were'nt fetched.

You could use npm's preinstall target to install the frontend dependencies.

Also try to see if it is possible to split the project into two different ones because this structure seem fragile and you actually loose the advantages of having a separate backend/frontend. ( plus your scripts get overly complicated )

EDIT:
Preinstall isn't specifically made for installing node modules, it is simply a step you can add to your package.json which will be run by npm before the install step, it can contain arbitrary script commands. In your case maybe try :

"scripts": {
    "preinstall": "cd frontend && npm install",
    "start": "node backend/server.js",
    "dev": "set NODE_ENV=DEVELOPMENT& nodemon backend/server",
    "prod": "set NODE_ENV=PRODUCTION& nodemon backend/server",
    "seeder": "node backend/utils/seeder.js",
    "build": "cd frontend && npm run build"
}
