Once you `eject`, you can't go back!** 35 | 36 | If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project. 37 | 38 | Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own. 39 | 40 | You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it. 41 | 42 | ## Learn More 43 | 44 | You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started). 45 | 46 | To learn React, check out the [React documentation](https://reactjs.org/). 47 | 48 | ### Code Splitting 49 | 50 | This section has moved here: [https://facebook.github.io/create-react-app/docs/code-splitting](https://facebook.github.io/create-react-app/docs/code-splitting) 51 | 52 | ### Analyzing the Bundle Size 53 | 54 | This section has moved here: [https://facebook.github.io/create-react-app/docs/analyzing-the-bundle-size](https://facebook.github.io/create-react-app/docs/analyzing-the-bundle-size) 55 | 56 | ### Making a Progressive Web App 57 | 58 | This section has moved here: [https://facebook.github.io/create-react-app/docs/making-a-progressive-web-app](https://facebook.github.io/create-react-app/docs/making-a-progressive-web-app) 59 | 60 | ### Advanced Configuration 61 | 62 | This section has moved here: [https://facebook.github.io/create-react-app/docs/advanced-configuration](https://facebook.github.io/create-react-app/docs/advanced-configuration) 63 | 64 | ### Deployment 65 | 66 | This section has moved here: [https://facebook.github.io/create-react-app/docs/deployment](https://facebook.github.io/create-react-app/docs/deployment) 67 | 68 | ### `npm run build` fails to minify 69 | 70 | This section has moved here: [https://facebook.github.io/create-react-app/docs/troubleshooting#npm-run-build-fails-to-minify](https://facebook.github.io/create-react-app/docs/troubleshooting#npm-run-build-fails-to-minify) 71 | -------------------------------------------------------------------------------- /package.json: -------------------------------------------------------------------------------- 1 | { 2 | "name": "react30", 3 | "version": "0.1.0", 4 | "private": true, 5 | "dependencies": { 6 | "@testing-library/jest-dom": "^5.17.0", 7 | "@testing-library/react": "^13.4.0", 8 | "@testing-library/user-event": "^13.5.0", 9 | "axios": "^1.6.0", 10 | "browserify-zlib": "^0.2.0", 11 | "react": "^18.2.0", 12 | "react-dom": "^18.2.0", 13 | "react-icons": "^4.11.0", 14 | "react-router-dom": "^6.16.0", 15 | "react-scripts": "5.0.1", 16 | "web-vitals": "^2.1.4" 17 | }, 18 | "scripts": { 19 | "start": "react-scripts start", 20 | "build": "react-scripts build", 21 | "test": "react-scripts test", 22 | "eject": "react-scripts eject" 23 | }, 24 | "eslintConfig": { 25 | "extends": [ 26 | "react-app", 27 | "react-app/jest" 28 | ] 29 | }, 30 | "browserslist": { 31 | "production": [ 32 | ">0.2%", 33 | "not dead", 34 | "not op_mini all" 35 | ], 36 | "development": [ 37 | "last 1 chrome version", 38 | "last 1 firefox version", 39 | "last 1 safari version" 40 | ] 41 | }, 42 | "devDependencies": { 43 | "webpack-cli": "^5.1.4" 44 | } 45 | } 46 | -------------------------------------------------------------------------------- /public/favicon.ico: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/Drop-X-Out/react-practice-30/b9587870f3d704bb8d33abf1cfe276eee23dd0b9/public/favicon.ico -------------------------------------------------------------------------------- /public/index.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 12 | 13 | 17 | 18 | 27 | React App 28 | 29 | 30 | 31 |
