Create a user logout Component


import React, { Component } from 'react'
export default class UserLogout extends Component {

  render() {
    return (
      <button>Logout</button>
    )
  }
}

import React, { Component } from 'react'

export default class UserLogout extends Component {

render() {

return (

<button>Logout</button>

)

}

In the above example code, you can see we created a “UserLogout” Class Component. Here we are rendering logout button but there is no logout function calling on button click.

Now we will implement logout function and this function will trigger when user click on logout button.


<button onClick={this.logout}>Logout</button>

<button onClick={this.logout}>Logout</button>

Define logout function with class component

Now we will define the logout function in-class component. When logout function will trigger then it will Clear the token in localStorage and redirect the user to the login page or home or where you want to redirect.


  logout = () => {
    localStorage.clear();
// you can also like localStorage.removeItem('Token');
    window.location.href = "/login";
  }

logout = () => {

localStorage.clear();

// you can also like localStorage.removeItem('Token');

window.location.href = "/login";

}

Complete Code


import React, { Component } from 'react'
export default class UserLogout extends Component {

 logout = () => {
    localStorage.clear();
// you can also like localStorage.removeItem('Token');
    window.location.href = "/login";
  }

  render() {
    return (
      <button onClick={this.logout}>Logout</button>
    )
  }
}

import React, { Component } from 'react'

export default class UserLogout extends Component {

logout = () => {

localStorage.clear();

// you can also like localStorage.removeItem('Token');

window.location.href = "/login";

}

render() {

return (

<button onClick={this.logout}>Logout</button>

)

}
