NPM installing nearly 202M of modules - this can't be right - reactjs

Question

So I am looking at my package.json file - and nothing looks particularly crazy:
{
"name": "application_name",
"version": "0.1.0",
"private": true,
"dependencies": {
"bootstrap-toggle": "^2.2.2",
"classnames": "^2.2.6",
"html-react-parser": "^0.4.6",
"jquery": "^3.3.1",
"react": "^16.4.1",
"react-bootstrap-toggle": "^2.3.1",
"react-cookie": "^3.0.4",
"react-dom": "^16.5.2",
"react-load-script": "0.0.6",
"react-router-dom": "^4.3.1",
"react-scripts": "1.1.4",
"react-timer-mixin": "^0.13.4"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build && robocopy .\\build ..\\www /MIR",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
}
}
I've tried npm install, npm install --production and npm install --express
No matter what npm command I write, I get the following:
added 1425 packages from 862 contributors and audited 14585 packages in 15.876s
It ultimately is 202M - this can't be right, that's a HUGE number of modules
This is for a React project I am working on.
I only made this question because none of the other answers seemed to work for my situation.
Is there a solution to this problem? I am intending on compiling this into a mobile app and 202M is a huge footprint for what is a pretty simple app.

Answer 1

202Mb is almost completely occupied with development dependencies, react-scripts.
react-scripts is a bundle consisting Webpack and other tools that are necessary to run the project. It is provided by Create React App, which is just an executable that creates boilerplate project with react-scripts:
This package includes scripts and configuration used by Create React
App.
node_modules size is adequate for complex configuration that CRA sets up. It doesn't affect the size of compiled application.
