Build a Basic CRUD App with Vue.js and Node

This article was originally published on the Okta developer blog. Thank you for supporting the partners who make SitePoint possible.

I’ve danced the JavaScript framework shuffle for years starting with jQuery, then on to Angular. After being frustrated with Angular’s complexity, I found React and thought I was in the clear. What seemed simple on the surface ended up being a frustrating mess. Then I found Vue.js. It just felt right. It worked as expected. It was fast. The documentation was incredible. Templating was eloquent. There was a unanimous consensus around how to handle state management, conditional rendering, two-way binding, routing, and more.

This tutorial will take you step by step through scaffolding a Vue.js project, offloading secure authentication to Okta’s OpenID Connect API (OIDC), locking down protected routes, and performing CRUD operations through a backend REST API server. This tutorial uses the following technologies but doesn’t require intimate knowledge to follow along:

About Vue.js

Vue.js is a robust but simple Javascript framework. It has one of the lowest barriers to entry of any modern framework while providing all the required features for high performance web applications.

This tutorial covers two primary builds, a frontend web app and backend REST API server. The frontend will be a single page application (SPA) with a homepage, login and logout, and a posts manager.

Okta’s OpenID Connect (OIDC) will handle our web app’s authentication through the use of Okta’s Vue SDK. If an unauthenticated user navigates to the posts manager, the web app should attempt to authenticate the user.

The server will run Express with Sequelize and Epilogue. At a high level, with Sequelize and Epilogue you can quickly generate dynamic REST endpoints with just a few lines of code.

You will use JWT-based authentication when making requests from the web app and Okta’s JWT Verifier in an Express middleware to validate the token. Your app will expose the following endpoints which all require requests to have a valid access token.

- GET /posts
- GET /posts/:id
- POST /posts
- PUT /posts/:id
- DELETE /posts/:id

Create Your Vue.js App

To get your project off the ground quickly you can leverage the scaffolding functionality from vue-cli. For this tutorial, you are going to use the progressive web app (PWA) template that includes a handful of features including webpack, hot reloading, CSS extraction, and unit testing.

If you’re not familiar with the tenets of PWA, check out our ultimate guide to progressive web applications.

To install vue-cli run:

npm install -g vue-cli

Next, you need to initialize your project. When you run the vue init command just accept all the default values.

vue init pwa my-vue-app
cd ./my-vue-app
npm install
npm run dev

Point your favorite browser to http://localhost:8080 and you should see the fruits of your labor:

Install Bootstrap

Let’s install bootstrap-vue so you can take advantage of the various premade components (plus you can keep the focus on functionality and not on custom CSS):

npm i --save bootstrap-vue bootstrap

To complete the installation, modify ./src/main.js to include bootstrap-vue and import the required CSS files. Your ./src/main.js file should look like this:

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import BootstrapVue from 'bootstrap-vue'
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue/dist/bootstrap-vue.css'

Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
  el: '#app',
  template: '<App/>',
  components: { App }

Add Authentication with Okta

Dealing with authentication in a web app is the bane of every developer’s existence. That’s where Okta comes in to secure your web applications with minimal code. To get started, you will need to create an OIDC application in Okta. Sign up for a forever-free developer account (or log in if you already have one).

Once logged in, create a new application by clicking “Add Application”.

Select the “Single-Page App” platform option.
