React js 组件渲染

Question

Hello I'm starting in react for now and I'm a little confused, I'm using routes / private routes, and so I created a components folder where I will have my login components and my login / index.js folder where I import this component, but I'm No doubt what better way to do this:

my app.js:

import React, { Component } from 'react';
import './App.css';

import Routes from './routes';

function App() {
  return (
          <Routes/>
  );
}

export default App;

my routes js:

export default function Routes(){
    return(
        <BrowserRouter>
            <Switch>
                <Route path="/" exact component = {Login}/> //só chama rota se o caminho for exato; 
                <PrivateRoute path="/home" component = {DashBoard}/>              
            </Switch>
        </BrowserRouter>
    );
}

my component / LoginForm:

import React, { Component } from 'react';

class LoginForm extends Component {
    constructor(props){
        super(props);
        this.state = {
            login:'',
            password:'',
            errors: {},
            isLoading: false
        };
        this.onSubmit = this.onSubmit.bind(this);
        this.onChange = this.onSubmit.bind(this);
    }
    onSubmit(e){
        e.preventDefault();
    }
    onChange(e){
        this.state({[e.target.name]: e.target.value});
    }

  render() {
    const { errors, login, password, isLoading } = this.state;
    return (
        <form onSubmit={this.onSubmit}>
            <label for="login">Login</label>
            <input type="text" id="login" value={login} error= {errors.login} onChange={this.onChange} placeholder="Informe seu login" />
            <label for="password">Senha</label>
            <input type="password" id="password" value={password} error= {errors.password} onChange={this.onChange}   placeholder="Informe sua senha"/>
        <button className="btnEnt" type="submit" disabled ={isLoading}>Entrar</button>
    </form>
    )
  }
}

export default LoginForm;

Now i'm in doubt as i will call my login comp in my index.js file from my login page

index.js

import React, { Component } from 'react';
import loginComp from '../../components/LoginForm';


class Login extends Component {
    render() {
      return (
          <loginComp />
      )
    }
  }

  export default Login;

I don't have an error, but it doesn't render anything on screen

Answer 1

Looks like you have a typo right here: <ionChange} placeholder="Informe sua senha"/> and you repasted the bottom portion of the code.

Assuming this was a mistake and successfully compiles, you're only going to want that bottom export default and make sure your pathing is correct to that file.

./pages/login does not exist, I believe you have named your login file LoginForm

Also, I am pretty sure . you need a div inside BrowserRouter, like so:

export default function Routes(){
    return(
        <BrowserRouter>
          <div>
            <Switch>
                <Route path="/" exact component={Login}/> 
                <PrivateRoute path="/home" component={DashBoard}/>              
            </Switch>
          </div>
        </BrowserRouter>
    );
}

Since, <loginComp/> is not a component you have created in LoginPage it is not rendering the data. You can simply change the

   import loginComp from '../../components/LoginForm';

to  import LoginForm from '../../components/LoginForm'; 

remember /components/LoginForm this is the file name you have saved and not the component you have created.

 render() {
      return (
          <LoginForm/>
      )
    }
