Beginner's Guide to Vue.js

Learn VueJS in simple and easy steps starting from basic to advanced concepts with examples

Vue.js is a frontend framework that is optimized for progressive integration. That means you can have a large app with only a couple Vue components integrated – or you could start from scratch and work completely within the Vue ecosystem.

Another thing that sets Vue apart is the lower learning curve compared to a lot of frameworks. Instead of having to understand complex topics, if you know HTML, CSS, and JavaScript, you’re already pretty close!

Like any framework, it adds a structure and utilities to your frontend so that your app is easier to extend as it grows, is more organized, and you don’t have to “reinvent the wheel” as often.

Vue is also really cool because it’s ecosystem is really well integrated – a lot of the utilities that would normally be 3rd party libraries are built by the Vue core maintainers, like Vue Router and Vuex.

Throughout this post, we’ll explore the key features of Vue, and create an app together!

Here’s what we’ll be building, though with some more interactive features. The like button will toggle from the heart outline to the red heart based on user clicks. Also, the character number will count down when someone types in the text box.

Go ahead and check out the HTML and CSS code above, we’ll be building off of the HTML with our Vue code.

Setting up a Vue App

For now, we’ll use a Vue CDN – we want a minimalist setup. In the future, you may want a more extensive environment, in which case you can use the Vue CLI.

Go to the settings button on Codepen, switch to the JavaScript tab, and search for Vue on CDNjs. This adds the Vue library to our project, so we can use all of the methods and features that Vue gives us.

Now, we need to create a Vue instance and attach it to our HTML in order to fully integrate Vue!

Let’s create a const that stores our Vue instance.

const app = new Vue()


We’re going to pass an object when we create this Vue app, it’ll have all our configuration and application logic for now.

The first thing we’re going to add to that object is el – which is the element that we want to be the base of our Vue app. In this case the element with the status class.

const app = new Vue({
  el: ".status"
})


Then, we’ll add our data. To test this out, let’s add the tweetText as data – so where we have Hello World! right now will become a variable. Down the road we’re going to make more tweets with different text, so it makes sense to make that piece of the tweet dynamic.

const app = new Vue({
    el: ".status",
    data: {
        tweetText: "Hello World!"
    }
})


When we want to add more dynamic data (or data that will change within our Vue app) we’ll add more attributes to this data object.

Now, we can use our newly created data in our HTML and plug in the variables that way! If you’ve ever used Handlebars or another templating language, it’s kind of like that.

If you go to the hardcoded “Hello World!” in the HTML, we can now replace it with {{tweetText}} which will pull from our Vue data!

<p class="tweet-text">
  {{ tweetText }}
</p>


Try to change your tweetText in Vue, and it’ll change in your output as well!

Let’s brainstorm for a second on what other data we have that will change within the course of our app.

  • The heart will toggle between liked and unliked
  • Our characters remaining will decrease when we type in the

Let’s go ahead and add attributes for those in our data object.

data: {
    tweetText: "Hello World!",
+    charactersRemaining: 280,
+    liked: false
}


We’ll also make charactersRemaining dynamic in the HTML.

<span class="characters-remaining">
  {{ charactersRemaining }} characters remaining
</span>


We’ll hold off on the liked attribute for now, we’ll come back to that in a second.

Methods

Now that we have our data, we need to make it update based on user actions.

We’re going to add another attribute to our Vue object – this one will store our methods.

const app = new Vue({
    el: ".status",
    data: {
        tweetText: "Hello World!",
        charactersRemaining: 280,
        liked: false
    },
    methods: {}
})


We have two “actions” for our app – toggling the like and changing the characters remaining number when the user types. Let’s work on the character counting first.

We’ll add a function to our methods object first:

methods: {
    countCharacters: function() {

    }
}


Let’s think about the logic for this function: we need to count how many characters the user has typed into the textarea. Then, we need to subtract that count from 280 (or our character limit).

Let’s create a data attribute for the comment text, and then update that every time the user types in the textarea.

  data: {
    tweetText: 'Hello World!',
    charactersRemaining: 280,
+    commentText: '',
    liked: false
  },

<textarea placeholder="tweet your reply" v-model="commentText"></textarea>


v-model is a directive that syncs our data attribute with what the user has typed into the textarea. So no matter how much or little they have typed in, commentText will match what they’ve typed. To take one quick step back, directives are HTML attributes that are provided by Vue, they’re prefixed by v-.

Okay, now back to our method. We can access our data in our methods with this.myDataAttribute (here’s a great reference on JavaScript’s this).

So, we can update the charactersRemaining with the following logic:

methods: {
    countCharacters: function() {
        this.charactersRemaining = 280 - this.commentText.length
    }
}


Now, we need to make sure that countCharacters runs every time the user types in the textarea.

Luckily, Vue has the v-on directive, and we can add the event after it so that we run the method each time that event takes place. In this case, v-on:input="countCharacters" will run the countCharacters method each time the user types in the textarea.

<textarea
  placeholder="tweet your reply"
  v-model="commentText"
  v-on:input="countCharacters"
></textarea>


Okay, now let’s step back and work on our toggleLike method.

We first need to add the method to our methods object.

methods: {
    ...
    toggleLike: function () {

    }
}


The body of the method should change this.liked to the opposite of what it currently is. So:

toggleLike: function () {
    this.liked = !this.liked
}


Now we need to make that action run.

On our reactions div, let’s add an event listener.

<div class="reactions like" v-on:click="toggleLike">
  ...
</div>


It’s time to introduce another Vue feature: conditionals!

Conditionals

Vue allows us to conditionally render data with the v-if directive.

Let’s add the following span-wrapped emoji within our reactions div:

<span v-if="liked">♥️</span>


Now, our red heart emoji only shows up if liked is true. Let’s also add a v-else to our heart outline emoji, so that it only renders if liked is false.

<span v-if="liked">♥️</span> <span v-else>♡</span>


Yay! Now our likes work!

If you had any issues with the above steps, here’s a Codepen with what we have so far.

Now that we have our interaction down, how would we create a bunch more tweets with the same functionality but different data? Components!

Components

Similar to other frontend frameworks, Vue apps are broken down into components. We compose components together in order to create full user interfaces. A good rule of thumb is that if a chunk of the user interface is used multiple times, it should be broken into a component.

In a production application, our tweet would probably be broken into subcomponents – we may have a component for the comment text area, one for the like functionality, one for the profile picture, etc. But, for now, we will just make the full tweet into a component so that we can easily create a bunch more tweets.

First, let’s move the logic from our Vue instance into a component.

The first argument to Vue.component is the name of the component, in this case “tweet”. We’re also turning data into a function that returns an object. This allows us to have multiple tweet component instance, each with separate data.

Vue.component("tweet", {
  data: function() {
    return {
      charactersRemaining: 280,
      commentText: "",
      liked: false
    }
  },
  methods: {
    countCharacters: function() {
      this.charactersRemaining = 280 - this.commentText.length
    },
    toggleLike: function() {
      this.liked = !this.liked
    }
  }
})


We also need the template for the component – or the HTML that the component will render. We’re going to grab all of the existing HTML and paste into a template attribute on our component.

template: `<div class="status">
  <div class="tweet-content">
    <img src="https://pbs.twimg.com/profile_images/1070775214370373633/borvu2Xx_400x400.jpg" class="logo" alt="Vue Vixens DC logo">
    <div class="tweet">
      <a href="https://twitter.com/vuevixensdc">Vue Vixens DC</a>
      <span>@VueVixensDC · Mar 20</span>
      <p class="tweet-text">
        {{ tweetText }}
      </p>
      <div class="reactions">
        <span v-on:click="toggleLike" class="like">
          <span v-if="liked">♥️</span>
          <span v-else>♡</span>
        </span>
      </div>
    </div>
  </div>
  <div class="comment-bar">
    <textarea placeholder="tweet your reply" v-model="commentText" v-on:input="countCharacters">
    </textarea>
    <span class="characters-remaining">
      {{ charactersRemaining }} characters remaining
    </span>
  </div>
</div>`


Now, we have a Vue component!

One other quick thing we need to add: the tweet text is going to be different from tweet to tweet. We’ll pass in different tweet text for each individual tweet through props – which allow us to pass data to a component from outside of that component. For now, we’ll just specify that our component has a prop associated with it.

Vue.component('tweet', {
  props: ['tweetText'],
...
})


We still have to have a Vue app though, so let’s add that back into our JavaScript:

new Vue({ el: "#app" })


Cool, now our JavaScript is set, we just have to handle our HTML. In our Vue instance, we’re looking for an element with the id app now, so let’s create that.

<div id="app"></div>


And, inside of our new Vue app, we’ll add some instances of our tweet component.

<div id="app">
  <tweet tweet-text="hello world!"></tweet>
  <tweet tweet-text="hi!"></tweet>
</div>


Notice how we’re passing in our tweetText prop – Vue converts the JavaScript camel case to kebab case in HTML. Outside of that change, our props look like HTML attributes.

Now our component should be good to go!

One more quick thing though, usually instead of hardcoding each tweet in the HTML, we’re going to want to loop through a data structure and create a tweet component for each of those items. Let’s look at how to do that in Vue!

We’re going to go into our Vue app instance and add some tweet data.

new Vue({
  el: "#app",
  data: {
    tweets: [
        { id: 1, tweetText: "hello world!" }, 
        { id: 2, tweetText: "hi!" }
    ]
  }
})


Now we’ll use another Vue directive, v-for in order to loop through the tweets array and create a tweet instance for each!

<div id="app">
  <tweet
    v-for="tweet in tweets"
    v-bind:key="tweet.id"
    v-bind:tweet-text="tweet.tweetText"
  ></tweet>
</div>


Notice that we use v-bind twice here – it allows us to dynamically update html attributes (or use variables within them). Keys are recommended whenever you use v-for – it allows Vue to identify the child elements better (more).

Awesome! Now we can create more tweets by adding an element to the tweets array!

Here’s all of that code together.

First, there’s a lot of cool features that you can add to the widget we just built. You can make the profile pictures different from tweet to tweet, along with the date and user data. You can also disable or highlight overflow text in our textarea. You could even use the Twitter API to use real tweets and even make the comment posting work!

• 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.

While Vuejs is simple to get started with, using it to build scalable web apps requires professionalism. Hence, you can approach a top Vue js development company in India to develop high-performing web apps.

Equipped with all the above features, it doesn't matter whether you want to build a small concept app or a full-fledged web app; Vue.Js is the most performant you can rely on.
