Can next.js and React.js work without Webpack?

Question

Do you know how my configuration is working without webpack installed? This configuration was originally made only to practice tests with Jest but the command "npm run dev" succeed to print a page. Is it a coincidence based on my code, my browser?

"scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start",
    "test": "jest"
  },
  "dependencies": {
    "axios": "^0.24.0",
    "fetch": "^1.1.0",
    "next": "10.1.3",
    "node-fetch": "^3.1.0",
    "react": "17.0.2",
    "react-dom": "17.0.2"
  },
  "devDependencies": {
    "@babel/preset-env": "^7.13.12",
    "@babel/preset-typescript": "^7.13.0",
    "@testing-library/dom": "^7.30.3",
    "@testing-library/jest-dom": "^5.11.10",
    "@testing-library/react": "^11.2.6",
    "@types/node": "^14.14.37",
    "@types/react": "^17.0.3",
    "babel-jest": "^26.6.3",
    "identity-obj-proxy": "^3.0.0",
    "jest": "^26.6.3",
    "jest-cli": "^26.6.3",
    "jest-dom": "^4.0.0",
    "jest-svg-transformer": "^1.0.0",
    "react-test-renderer": "^17.0.2",
    "ts-jest": "^27.1.2",
    "ts-node": "^9.1.1",
    "typescript": "^4.2.3"
  }
}

Thanks for your help.

Answer 1

webpack is a React dependency: https://github.com/facebook/react/blob/main/package.json

Answer 2

Next.js have internal config files for such cases. I think you can check next.config.js file to see the webpack configuration.

Have a look at this link .
