Learn to Integrate Firebase Authentication With your Nuxt JS project

Nuxt JS is a framework to build Universal Vue.js Applications, which means you can deploy your project to any platform or hosting provider. Using NuxtJS and Firebase storage together will let you take advantage of cloud-based authentication for users with the ability to sign in on one device but retain their state across multiple devices without having access keys saved locally on each computer/device.

Nuxt JS is a framework for building universal and progressive web applications. It provides features like hot reloading, SSR (Server-Side Rendering), and authentication with Firebase. The “nuxt firebase auth” is a tutorial that will help you integrate Firebase Authentication with your Nuxt JS project.

You’ll learn how to utilize Google’s Firebase authentication service in your Nuxt Js app in this article.

After reading this tutorial, you will be able to create and authenticate users in your app using email and passwords. 

So, if you want to or are thinking about using Firebase authentication in one of your Nuxt Js applications, this post is for you.

In Nuxt Js, there are several requirements for authenticating with Firebase.

• yarn/npm package manager with Node.js installed version (14.x or above)
• Visual Studio Code is my preferred code editor.
• We’ll need a Google account to utilize Firebase.
• I won’t suggest this lesson to complete novices in Nuxt Js since it requires a basic understanding of the language.

You may refer to the code in the GitHub repository if you run into any problems throughout the course.

What is Firebase Authentication and how does it work?

Google has created a platform called Firebase. Backend as a Service (BaaS) provider Firebase offers a number of services for online and mobile app development. 

 Such as:

• Authentication of users
• Databases with scalability
• Messaging in the cloud
• Functions of cloud code
• Integration of social media
• Storage of files

plus a whole lot more

And Firebase Authentication is one of the Firebase services that enables you to simply install authentication in your web app and therefore increase its security.

Let’s get started:

First and foremost, we’ll create our Firebase project. 

Go to firebase.google.com and sign in using our Google account.

Create a project, give it whatever name you like, accept the rules, and then click proceed.

Then uncheck Enable Google Analytics for this project (since we don’t need it) and click Create Project.

Wait for it to complete for a few seconds before clicking on continue.

.

To build a web app, go to the dashboard and click this button (seen below).

Now give your web app whatever name you like and click Register app.

Now you’ll see this page, which contains your API key and other personal information; be careful to keep this information secret.

You should copy these 6 items and put them in a notebook or somewhere else since you will need them in the future.

projectId: “, storageBucket: “, messagingSenderId: “, appId: “, measurementId: “, apiKey: “, authDomain: “, projectId: “, storageBucket: “, messagingSenderId: “, appId: “, measurementId: “

Click Continue to Console once you’ve saved these data.

We’ll utilize the firebase authentication service using email and password now that we’ve developed the app in Firebase.

After that, go to the Build tab and then to the Authentication tab.

Now press the start button. 

Here, choose Email/Password.

Activate the top one and save it.

That’s all there is to the firebase section. Let’s create a Nuxt js project now.

Open your vscode editor and run the command below into the terminal. It will construct the “nuxt-auth” Nuxt Js project.

create nuxt-app nuxt-auth yarn

When creating the project, there will be a few settings to choose from; we’ll be using other things in addition to Nuxt Js, so here are the ones we’ll need:

Note To choose Node js modules, press space.

After that, we’ll need to set up a firebase server in our project. To do so, type the command below and press Enter.

add yarn to the firebase

Then type the following command and click enter to install the Nuxt module as well.

@nuxtjs/firebase yarn add

After the installation is complete, go to your Nuxt js project by entering cd nuxt-auth and pressing enter, then executing yarn dev and pressing enter to start the server.

This should open your browser, and you should see something like this:

Let’s tidy up a little bit so we can go back to coding. Delete NuxtLogo.vue and Tutorial.vue from the Components folder. Remove the Tutorial component from index.vue after deleting these files. Your index.vue file should now look like this:

Now open your nuxt.config.js file and make the following changes: 

This should be replaced. 

[/ https://go.nuxtjs.dev/axios ‘@nuxtjs/axios’], @nuxtjs/axios, @nuxtjs/axios, @nuxtjs/axios, @nuxtjs/axios

To this:

[/ https://go.nuxtjs.dev/axios ‘@nuxtjs/axios’, [‘@nuxtjs/firebase’, ‘@nuxtjs/firebase’, ‘@nuxtjs/firebase’, ‘@nuxtjs/firebase’, ‘@nuxtjs/firebase’, ‘@n config: apiKey: “, authDomain: “, projectId: “, storageBucket: “, messagingSenderId: “, appId: “, measurementId: ” ]], it might be any other service.

Remember how I instructed you to make a duplicate of your Firebase API keys and other personal data? Now you must copy and paste the information into this box. 

Nuxt js is now linked to Firebase. On our sites, we can now utilize Firebase authentication.

In Nuxt Js, you may create a sign-up page.

First, we’ll build a sign-up feature that allows people to sign up for our app using their email address and password. After that, we’ll lead them to a different page. 

Let’s begin by creating a basic sign-up HTML page in index.vue, modeling the email and password input fields with an email and password variable so we can extract the data, and then creating a register button that will execute the “createUser” method when pushed.

This is how the whole code will look:

We specified two variables, email and password, in the scripts section, which will represent the data from the input forms we built previously.

Then we’ll build a function called createUser that will contact our firebase auth instance, which has a “createUserWithEmailAndPassword” method that accepts an email and a password as parameters to create a new user object in firebase.

After that, we’ll just send customers to another page called aftersignup.

Let’s create a page called aftersignup that will appear after the user has registered.

Create a file called aftersignup.vue in your pages folder, and then display anything you want to show the user after they’ve registered, for example:

This is how the whole registration page will look:

Following the registration, it will appear as follows:

Let’s construct a login page now that we’ve established the registration page using the Firebase authentication API.

In Nuxt Js, you may make a login page.

To begin, we’ll design a login feature that will allow users to sign in to our app using their email address and password. We will then redirect them to another page when they have successfully logged in. 

First, create a login file. in the pages folder vue

Then, in login.vue, make a basic login HTML page, modeling the email and password input forms with an email and password variable, like we did in the registration page, and then create a login button that, when pushed, runs a function named “loginUser.”

This is how the whole code will look:

Here, we created a loginUser function that will call our auth object from Firebase, which includes a “signInWithEmailAndPassword” method that accepts an email and password as parameters.

After that, we’ll just redirect customers to another page called afterlogin.

Now let’s create a page called afterlogin that will appear after the user has successfully logged in.

Create a file called afterlogin.vue in your pages folder, and then display anything you want the user to see after they log in, such as:

This is how the whole login page will look:

Following the registration, it will appear as follows:

Finally, launch the server using the following command to view all of the changes.

yarn dev

Also, the app should be up and running.

Once you’ve completed this build, you may experiment with the code by adding alternative authentication systems such as Google authentication, Facebook authentication, and so on.

Here’s the GitHub repository you may use for reference if you have any issues or queries about the code.
