How to Implement JWT Authentication in Vue/Nuxt Applications
Authentication in SPAs is often a hot topic, and even more-so for those who aren’t sure of the best method for implementing an authentication system with all the necessary features and one that can handle the most common edge cases.
Although we won’t cover writing the backend JWT or authentication implementation, there are various articles that describe the best methods for various languages and frameworks, depending on your needs. Regardless of your choice, you’ll want to make sure to implement the three core features necessary for the frontend — registration, login and access token refreshing via refresh tokens. We’ll discuss a basic implementation of some of these endpoints, but they are still completely flexible. It’s also assumed that you have already setup a basic Nuxt application in universal rendering mode.
Getting Started
For the frontend, we’ll be making use of three essential packages — vuex-persistedstate, js-cookie and @nuxtjs/axios. The first allows us to persist Nuxt module state into a store of our choosing (cookies!), which will allow us to store tokens and user data accessible to both the Nuxt server, as well as the client, which in turn allows for authenticated calls from both ends. The second will make parsing cookies easier, while the last is a common Nuxt package, providing an all-inclusive package for HTTP calls.
Let’s start by installing those.
npm install --save vuex-persistedstate js-cookie @nuxtjs/axios
VueX State Persistence
To make authenticated API calls from both the server and browser (client), we need to ensure that the tokens are accessible from both ends. vuex-persistedstate simplifies this, and with the help of js-cookie will persist the tokens to a cookie.
After installing the packages, we’ll need to configure the vuex-persistedstate with a plugin.
// plugins/local-storage.js
import createPersistedState from 'vuex-persistedstate'
import * as Cookies from 'js-cookie'
import cookie from 'cookie'
// access the store, http request and environment from the Nuxt context
// https://nuxtjs.org/api/context/
export default ({ store, req, isDev }) => {
createPersistedState({
key: 'authentication-cookie', // choose any name for your cookie
paths: [
// persist the access_token and refresh_token values from the "auth" store module
'auth.access_token',
'auth.refresh_token',
],
storage: {
// if on the browser, parse the cookies using js-cookie otherwise parse from the raw http request
getItem: key => process.client ? Cookies.getJSON(key) : cookie.parse(req.headers.cookie || '')[key],
// js-cookie can handle setting both client-side and server-side cookies with one method
// use isDev to determine if the cookies is accessible via https only (i.e. localhost likely won't be using https)
setItem: (key, value) => Cookies.set(key, value, { expires: 14, secure: !isDev }),
// also allow js-cookie to handle removing cookies
removeItem: key => Cookies.remove(key)
}
})(store)
}
plugins/local-storage.js — configuring vuex-persistedstate
Don’t forget to add this plugin to your nuxt.config.js!
plugins: [
'~/plugins/local-storage',
],
VueX Store
We’ll also need to setup the VueX store, which will be where we store data about the user, the access token and refresh token. We’ll also need to include actions for making API calls to register, login and refresh a user, as well as mutations to commit the returned data to the state.
Although the structure is easily modifiable, you should end up with something like this…
// store/auth.js
// reusable aliases for mutations
export const AUTH_MUTATIONS = {
SET_USER: 'SET_USER',
SET_PAYLOAD: 'SET_PAYLOAD',
LOGOUT: 'LOGOUT',
}
export const state = () => ({
access_token: null, // JWT access token
refresh_token: null, // JWT refresh token
id: null, // user id
email_address: null, // user email address
})
export const mutations = {
// store the logged in user in the state
[AUTH_MUTATIONS.SET_USER] (state, { id, email_address }) {
state.id = id
state.email_address = email_address
},
// store new or updated token fields in the state
[AUTH_MUTATIONS.SET_PAYLOAD] (state, { access_token, refresh_token = null }) {
state.access_token = access_token
// refresh token is optional, only set it if present
if (refresh_token) {
state.refresh_token = refresh_token
}
},
// clear our the state, essentially logging out the user
[AUTH_MUTATIONS.LOGOUT] (state) {
state.id = null
state.email_address = null
state.access_token = null
state.refresh_token = null
},
}
export const actions = {
async login ({ commit, dispatch }, { email_address, password }) {
// make an API call to login the user with an email address and password
const { data: { data: { user, payload } } } = await this.$axios.post(
'/api/auth/login',
{ email_address, password }
)
// commit the user and tokens to the state
commit(AUTH_MUTATIONS.SET_USER, user)
commit(AUTH_MUTATIONS.SET_PAYLOAD, payload)
},
async register ({ commit }, { email_addr, password }) {
// make an API call to register the user
const { data: { data: { user, payload } } } = await this.$axios.post(
'/api/auth/register',
{ email_address, password }
)
// commit the user and tokens to the state
commit(AUTH_MUTATIONS.SET_USER, user)
commit(AUTH_MUTATIONS.SET_PAYLOAD, payload)
},
// given the current refresh token, refresh the user's access token to prevent expiry
async refresh ({ commit, state }) {
const { refresh_token } = state
// make an API call using the refresh token to generate a new access token
const { data: { data: { payload } } } = await this.$axios.post(
'/api/auth/refresh',
{ refresh_token }
)
commit(AUTH_MUTATIONS.SET_PAYLOAD, payload)
},
// logout the user
logout ({ commit, state }) {
commit(AUTH_MUTATIONS.LOGOUT)
},
}
export const getters = {
// determine if the user is authenticated based on the presence of the access token
isAuthenticated: (state) => {
return state.access_token && state.access_token !== ''
},
}
store/auth.js — the essential implementation of the auth store module
Now that we have a state in place, you’ll need to create form components for the login and registration pages, which also won’t be covered here. Essentially, your forms should call the authentication module actions to login or register the user.
const email_address = 'me@example.com'
const password = 'abc123'
await $store.dispatch('auth/login', { email_address, password })
A sample login API call
With the state and forms in place, and the ability to authenticate users, we can implement authenticated API requests!

How To Set Up Two-Factor Authentication in cPanel
What is 2FA
Two-Factor Authentication (or 2FA as it often referred to) is an extra layer of security that is used to provide users an additional level of protection when securing access to an account.
Employing a 2FA mechanism is a vast improvement in security over the Singe-Factor Authentication method of simply employing a username and password. Using this method, accounts that have 2FA enabled, require the user to enter a one-time passcode that is generated by an external application. The 2FA passcode (usually a six-digit number) is required to be input into the passcode field before access is granted. The 2FA input is usually required directly after the username and password are entered by the client.

• Vue.JS provides responsive visual components.
Top 7 Reasons to Choose Vue JS for Web Application Development
Vue js development has certain benefits, which will encourage you to use it in your projects. For example, Vue.js is similar to Angular and React in many aspects, and it continues to enjoy increasing popularity compared to other frameworks.
The framework is only 20 kilobytes in size, making it easy for you to download files instantly. Vue.js easily beats other frameworks when it comes to loading times and usage.
Take a look at the compelling advantages of using Vue.Js for web app development.
#1 Simple Integration
Vue.Js is popular because it allows you to integrate Vue.js into other frameworks such as React, enabling you to customize the project as per your needs and requirements.
It helps you build apps with Vue.js from scratch and introduce Vue.js elements into their existing apps. Due to its ease of integration, Vue.js is becoming a popular choice for web development as it can be used with various existing web applications.
You can feel free to include Vue.js CDN and start using it. Most third-party Vue components and libraries are additionally accessible and supported with the Vue.js CDN.
You don't need to set up node and npm to start using Vue.js. This implies that it helps develop new web applications, just like modifying previous applications.
The diversity of components allows you to create different types of web applications and replace existing frameworks. In addition, you can also choose to hire Vue js developers to use the technology to experiment with many other JavaScript applications.
#2 Easy to Understand
One of the main reasons for the growing popularity of Vue.Js is that the framework is straightforward to understand for individuals. This means that you can easily add Vue.Js to your web projects.
Also, Vue.Js has a well-defined architecture for storing your data with life-cycle and custom methods. Vue.Js also provides additional features such as watchers, directives, and computed properties, making it extremely easy to build modern apps and web applications with ease.
Another significant advantage of using the Vue.Js framework is that it makes it easy to build small and large-scale web applications in the shortest amount of time.
#3 Well-defined Ecosystem
The VueJS ecosystem is vibrant and well-defined, allowing Vue.Js development company to switch users to VueJS over other frameworks for web app development.
Without spending hours, you can easily find solutions to your problems. Furthermore, VueJs lets you choose only the building blocks you need.
Although the main focus of Vue is the view layer, with the help of Vue Router, Vue Test Utils, Vuex, and Vue CLI, you can find solutions and recommendations for frequently occurring problems.
The problems fall into these categories, and hence it becomes easy for programmers to get started with coding right away and not waste time figuring out how to use these tools.
The Vue ecosystem is easy to customize and scales between a library and a framework. Compared to other frameworks, its development speed is excellent, and it can also integrate different projects. This is the reason why most website development companies also prefer the Vue.Js ecosystem over others.
#4 Flexibility
Another benefit of going with Vue.Js for web app development needs is flexibility. Vue.Js provides an excellent level of flexibility. And makes it easier for web app development companies to write their templates in HTML, JavaScript, or pure JavaScript using virtual nodes.
Another significant benefit of using Vue.Js is that it makes it easier for developers to work with tools like templating engines, CSS preprocessors, and type checking tools like TypeScript.
#5 Two-Way Communication
Vue.Js is an excellent option for you because it encourages two-way communication. This has become possible with the MVVM architecture to handle HTML blocks. In this way, Vue.Js is very similar to Angular.Js, making it easier to handle HTML blocks as well.
With Vue.Js, two-way data binding is straightforward. This means that any changes made by the developer to the UI are passed to the data, and the changes made to the data are reflected in the UI.
This is also one reason why Vue.Js is also known as reactive because it can react to changes made to the data. This sets it apart from other libraries such as React.Js, which are designed to support only one-way communication.
#6 Detailed Documentation
One essential thing is well-defined documentation that helps you understand the required mechanism and build your application with ease. It shows all the options offered by the framework and related best practice examples.
Vue has excellent docs, and its API references are one of the best in the industry. They are well written, clear, and accessible in dealing with everything you need to know to build a Vue application.
Besides, the documentation at Vue.js is constantly improved and updated. It also includes a simple introductory guide and an excellent overview of the API. Perhaps, this is one of the most detailed documentation available for this type of language.
#7 Large Community Support
Support for the platform is impressive. In 2018, support continued to impress as every question was answered diligently. Over 6,200 problems were solved with an average resolution time of just six hours.
To support the community, there are frequent release cycles of updated information. Furthermore, the community continues to grow and develop with backend support from developers.
Wrapping Up
VueJS is an incredible choice for responsive web app development. Since it is lightweight and user-friendly, it builds a fast and integrated web application. The capabilities and potential of VueJS for web app development are extensive.
