I'm developing a ReactJS app with Babel and Webpack. I am using the create-react-app facebook script so it handles the Webpack´s configuration. My problem is that I created a js file and add:
var childProcess = require('child_process');
But when I want to compile the new version i get the following error :
Module not found: 'child_process'.
I don't know what to do with this . I have read that adding custom configurations to the webpack.config.js may be the solution but i am using create react app so I don't have the Webpack configuration. I tried running npm run eject and create my own webpack.config.js but it doesn't work.
I hope somebody could help me.

js allows single-threaded, non-blocking performance but running a single thread in a CPU cannot handle increasing workload hence the child_process module can be used to spawn child processes. The child processes communicate with each other using a built-in messaging system.
The node:child_process module provides the ability to spawn subprocesses in a manner that is similar, but not identical, to popen(3) .
What is Module Pattern? The module pattern is a special Design pattern in which we use IFFI (Immediately invoked function expression), and we return an object. Inside of that object, we can have functions as well as variables.
You need to configure the correct target inside the webpack configuration: https://webpack.github.io/docs/configuration.html#target
module.exports = {
entry: './path/to/my/entry/file.js',
...
target: 'node',// we can use node.js modules after adding this configuration
};
