Webpack loader swears. How to use jsx source files inside node_modules?

Question

Node.js

structure:

./node_modules/packageName/file.jsx
./main.js

main.js

import * as CUSTOM from './node_modules/packageName/file.jsx'

file.jsx

export function custom() {

}

webpack error

ERROR in ./~/packageName/src/js/custom.jsx
Module parse failed:PATH_TO_PROJECT/node_modules/packageName/file.jsx Line 1: Unexpected token

| export function CUSTOM() {
| }
| 
 @ ./src/js/main.js

At the same time, importing the same file, if it lies next to main.js, works successfully

Answer 1
