import React from 'react'; import {BrowserRouter as Router , Route} from "react-router-dom"; import "bootstrap/dist/css/bootstrap.min.css"; import login from "./components/homepage.component"; import Navbar from "./components/navbar.component" import classes from "./components/classes.component" import studentscreen from "./components/student.component" import majors from "./components/majors.component" import sections from "./components/sections.components" import passerror from "./components/passerror.component" import calendar from "./components/calendar.component" import faculty from "./components/faculty.component" import facultyhome from "./components/facultyhome.component" import spring from "./components/spring.component" import audit from "./components/audit.component" import masterspring from "./components/masterspring.component" import masterfall from "./components/masterfall.component" import register from "./components/register.component" import mark from "./components/add.component" import fall from "./components/fall.component" import transcript from "./components/transcript.component" function App() { return ( <Router> <Navbar /> <br/> <div className="Pineapple"> <Route path="/" exact component={login} /> <Route path="/student/:id" exact component={studentscreen} /> <Route path="/classes/:id" exact component={classes} /> <Route path="/majors/:name" exact component={majors} /> <Route path="/sections/:name" exact component={sections} /> <Route path="/passerror" exact component={passerror} /> <Route path="/calendar/:id" exact component={calendar} /> <Route path="/spring" exact component={spring} /> <Route path="/audit/:major" exact component={audit} /> <Route path="/adddrop/:id" exact component={mark}/> <Route path="/masterfall" exact component={masterfall} /> <Route path="/masterspring" exact component={masterspring} /> <Route path="/register" exact component={register} /> <Route path="/faculty" exact component={faculty}/> <Route path="/facultyhome/:id" exact component={facultyhome}/> <Route path="/fall" exact component={fall}/> <Route path="/transcript/:id" exact component={transcript}/> </div> </Router> ); } export default App;and that is my package.json
