Online payment has become a common thing now. There are many websites which use payment gateways. Sometimes we have to integrate the payment gateway on our website as well.

It’s common to show a 404 error page if a user goes to a wrong path that is not on our website. A 404 error page is used to show the user a not found page instead of a blank page.

Here I will show handling 404 error page in Vue router.

For the 404 error page, create a new component called NotFoundPage.vue and add the following code.

<template>
    <div>
        <center>
            <h1>404 not found</h1>
            <h2>it seems you're in the wrong page</h2>
        </center>
    </div>
</template>

Now go to the router.js file and add the following

import NotFoundPage from './compnents/NotFoundPage.vue{
  path: '*',
  component: NotFoundPage
}

we have added the * character as the route for handling 404 errors. So if any user navigates to a wrong path, our NotFoundPage will be rendered.

Introduction

In this tutorial, we will create a basic CRUD (Create Read Update Delete) application using Node.js. We will use Express.js for routing and MongoDB to store our data.

Node.js is an open-source, cross-platform, JavaScript runtime environment that executes JavaScript code outside of a browser.
Express.js is one of the popular web frameworks for Node.js. It simplifies routing, creating middleware etc.
MongoDB is one of the most popular databases used by modern apps. It is an opensource, cross-platform NoSQL database.
