10 | Open [http://localhost:3000](http://localhost:3000) to view it in the browser. 11 | 12 | The page will reload if you make edits.
13 | You will also see any lint errors in the console. 14 | 15 | ### `npm test` 16 | 17 | Launches the test runner in the interactive watch mode.
18 | See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information. 19 | 20 | ### `npm run build` 21 | 22 | Builds the app for production to the `build` folder.
23 | It correctly bundles React in production mode and optimizes the build for the best performance. 24 | 25 | The build is minified and the filenames include the hashes.
26 | Your app is ready to be deployed! 27 | 28 | See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information. 29 | 30 | ### `npm run eject` 31 | 32 | **Note: this is a one-way operation. Once you `eject`, you can’t go back!** 33 | 34 | 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. 35 | 36 | 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. 37 | 38 | 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. 39 | 40 | ## Learn More 41 | 42 | You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started). 43 | 44 | To learn React, check out the [React documentation](https://reactjs.org/). 45 | 46 | ### Code Splitting 47 | 48 | This section has moved here: https://facebook.github.io/create-react-app/docs/code-splitting 49 | 50 | ### Analyzing the Bundle Size 51 | 52 | This section has moved here: https://facebook.github.io/create-react-app/docs/analyzing-the-bundle-size 53 | 54 | ### Making a Progressive Web App 55 | 56 | This section has moved here: https://facebook.github.io/create-react-app/docs/making-a-progressive-web-app 57 | 58 | ### Advanced Configuration 59 | 60 | This section has moved here: https://facebook.github.io/create-react-app/docs/advanced-configuration 61 | 62 | ### Deployment 63 | 64 | This section has moved here: https://facebook.github.io/create-react-app/docs/deployment 65 | 66 | ### `npm run build` fails to minify 67 | 68 | This section has moved here: https://facebook.github.io/create-react-app/docs/troubleshooting#npm-run-build-fails-to-minify 69 | -------------------------------------------------------------------------------- /Frontend/src/App.js: -------------------------------------------------------------------------------- 1 | import React, { useEffect, useState } from 'react'; 2 | import { Route, BrowserRouter as Router, Switch} from 'react-router-dom' 3 | 4 | import Nav from './component/Nav' 5 | 6 | import Main from './page/Main' 7 | import NF from './page/NF' 8 | import Admin from './page/Admin' 9 | import AdminUser from './page/AdminUser' 10 | import User from './page/User' 11 | import Status from './page/Status'; 12 | import Rank from './page/rank'; 13 | import Problem from './page/Problem'; 14 | import Submit from './page/Submit'; 15 | import EditProblem from './page/EditProblem'; 16 | import ShowProblem from './page/ShowProblem'; 17 | import Submission from './page/Submission'; 18 | import Auth from './page/Auth'; 19 | 20 | 21 | import {BACKEND_URL} from './util/config' 22 | import {UserContext} from './util/UserContext' 23 | 24 | import ReactLoading from 'react-loading'; 25 | // import queryString from 'query-string' 26 | 27 | function App() { 28 | // if(query.glaxoj) { 29 | // // localStorage.setItem('glaxoj', query.glaxoj) 30 | // history.push('/') 31 | // } 32 | 33 | const [user, setUser] = useState(null) 34 | const [loading, setLoading] = useState(true) 35 | 36 | useEffect(()=>{ 37 | 38 | (async()=>{ 39 | //console.log(`${BACKEND_URL}/user`) 40 | try{ 41 | if(!user) { 42 | const response = await fetch( `${BACKEND_URL}/user`, { 43 | credentials: 'include', 44 | withCredentials: true, 45 | headers: { 46 | 'Content-Type': 'application/json' 47 | }, 48 | }) 49 | const data = await response.json() 50 | //console.log(data) 51 | if(data.success === "yes") { 52 | setUser(data.data) 53 | //console.log(user) 54 | } else { 55 | setUser(null) 56 | } 57 | } 58 | 59 | setLoading(false) 60 | } catch(err) { 61 | setLoading(false) 62 | } 63 | })() 64 | 65 | // console.log(user) 66 | 67 | },[]) 68 | 69 | 70 | 71 | return ( 72 | 73 | { loading &&
