Routes not working in react even when trying to use Routes and Router

Time:12-22

I'm following this tutorial: https://ibaslogic.com/routing-with-react-router/

When I render the page, I recieve this error

Uncaught Error: A <Route> is only ever to be used as the child of <Routes> element, never rendered directly. Please wrap your <Route> in a <Routes>.

I've tried to wrap the Route in Routes as the warning suggests. I still get an error that I need Router which I already have. I've also tried the suggestions here react-router, routes not working without success

Here is my js component file where the error is taking place:

import React, { useState, useEffect } from "react"
import TodosList from "./TodosList";
import Header from "./Header";
import InputTodo from "./InputTodo";
import { v4 as uuidv4 } from "uuid";
import "./App.css"
import { Route, Switch } from "react-router-dom"

const TodoContainer = () => {
  const [todos, setTodos] = useState(getInitialTodos())

  const handleChange = id => {
    setTodos(prevState =>
      prevState.map(todo => {
        if (todo.id === id) {
          return {
            ...todo,
            completed: !todo.completed,
          }
        }
        return todo
      })
    )
  }

  const delTodo = id => {
    setTodos([
      ...todos.filter(todo => {
        return todo.id !== id
      }),
    ])
  }

  const addTodoItem = title => {
    const newTodo = {
      id: uuidv4(),
      title: title,
      completed: false,
    }
    setTodos([...todos, newTodo])
  }

  const setUpdate = (updatedTitle, id) => {
    setTodos(
      todos.map(todo => {
        if (todo.id === id) {
          todo.title = updatedTitle
        }
        return todo
      })
    )
  }

  // useEffect(() => {
  //   console.log("test run")
  
  //   // getting stored items
  //   const temp = localStorage.getItem("todos")
  //   const loadedTodos = JSON.parse(temp)
  
  //   if (loadedTodos) {
  //     setTodos(loadedTodos)
  //   }
  // }, [])

  function getInitialTodos() {
    // getting stored items
    const temp = localStorage.getItem("todos")
    const savedTodos = JSON.parse(temp)
    return savedTodos || []
  }

  useEffect(() => {
    // storing todos items
    const temp = JSON.stringify(todos)
    localStorage.setItem("todos", temp)
  }, [todos])

  

  return (
    <Route path="/">
      <div className="container">
        <div className="inner">
          <Header />
          <InputTodo addTodoProps={addTodoItem} />
          <TodosList
            todos={todos}
            handleChangeProps={handleChange}
            deleteTodoProps={delTodo}
            setUpdate={setUpdate}
          />
        </div>
      </div>
    </Route>
  )
}

export default TodoContainer

Here is my index.js:

import React from "react"
import ReactDOM from "react-dom"
//component file
import TodoContainer from "./functionBased/components/TodoContainer"
import { BrowserRouter as Router } from "react-router-dom"

//stylesheet
import "./functionBased/App.css"

ReactDOM.render(
  <React.StrictMode>
    <Router>
      <TodoContainer />
    </Router>
  </React.StrictMode>,
  document.getElementById("root")
)

I'm unsure how to make Route work. Thank you

Not sure I understand the problem correctly but maybe try in the index.js to change

<TodoContainer />

with:

<Route exact path="/" element={<TodoContainer />}/>

also remember to import Route from react-router-dom

import {BrowserRouter as Router, Route} from 'react-router-dom';

This blogpost by Esteban Herrera gives a good example on how to use react router. https://blog.logrocket.com/react-router-dom-tutorial-examples/

CodePudding user response:

I think you need to do something like that:

  • remove Route tag from your component folder
  • add Route tag to your index.js file like that
import {BrowserRouter as Router, Route} from 'react-router-dom';

...

 <Router>
     <Route exact path="/" element={<TodoContainer />}/>
 </Router>
