5 Practical Examples For Learning Vue.js

Category: JavaScript, Tutorials

We’ve already covered Angular.js and React in previous articles but there is a new frontend library that we think is worth your time. It’s called Vue.js and it has gathered a large community of enthusiastic developers.

The philosophy behind Vue.js is to provide the simplest possible API for creating real-time, two-way data binding between the view (HTML) and the model (a JavaScript object). As you will see in the following examples, the library holds true to that idea and working with it is effortless and enjoyable, without compromising on any functionality.

Getting Started

The easiest way to install Vue.js is to simply include it with a <script> tag at the end of your HTML’s body. The entire library is located in a single JavaScript file which you can download from the official website or import directly via CDN:

<script src=""></script>

If you want to use the library in a Node.js project, vue is available as an npm module. There is also an official CLI, which allows users to quickly setup their whole project based on premade template builds.

Below are five editors containing example apps we’ve built for you. The code has lots of comments and is separated in tabs for each file, making it really easy to follow. The editors have Vue.js built-in so don’t be afraid to experiment. Also, you can download an archive containing all the examples from the Download button near the top of this article.

1. Navigation Menu

To kick things off we’re going to build a simple navigation bar. There are a few basic components almost every Vue.js app need to have. They are:

  • The model, or in other words our app’s data. In Vue.js this is simply a JavaScript object containing variables and their initial values.
  • An HTML template, the correct terminology for which is view. Here we chose what to display, add event listeners, and handle different usages for the model.
  • ViewModel – a Vue instance that binds the model and view together, enabling them to communicate with each other.

The idea behind these fancy words is that the model and the view will always stay in sync. Changing the model will instantly update the view, and vice versa. In our first example this is shown with the active variable, representing which menu item is currently selected.

As you can see working with the library is pretty straightforward. Vue.js does a lot of the work for us and provides familiar, easy to remember syntax:

  • simple JavaScript object for all the options
  • {{double brackets}} for templating
  • v-something inline attributes for adding functionality directly in the HTML.

2. Inline Editor

In the previous example our model had only a couple of predefined values.  If we want to give the users the ability to set any data, we can do two-way binding and link together an input field with a model property.  When text is entered, it is automatically saved in the text_content model, which then causes the view to update.

Another thing to note in the above code is the v-if attribute . It show or hides a whole element depending on the truthfulness of a variable. You can read more about it here.

3. Order Form

This example illustrates multiple services and their total cost. Since our services are stored in an array, we can take advantage of the v-for directive to loop through all of the entries and display them. If a new element is added to the array or any of the old ones is changed, Vue.js will automatically update and show the new data.

To display the prices in a correct format we use one of the available filters that come built-in with Vue.js. They allow us to lazily modify the model data – in this case the currency filter is perfect, as it adds a dollar sign and proper number decimals. Just like in Angular filters are applied using the | syntax – {{ some_data | filter }}.

4. Instant Search

Here we will create an app, that exhibits some of the articles on our website. The app will also have a search field allowing us to filter which articles are displayed.  There is a filterBy filter available, but it doesn’t do exactly what we need it to, so instead we will be creating our own custom filter.

The input field is bind to the searchString model. When text is entered the model is instantly updated and passed on to the searchFor filter. This way we can create a real-time search without having to worry about rendering or setting up event listeners – Vue.js handles all that!

5. Switchable Grid

In our last example we will demonstrate a common scenario where a page has different layout modes. Just like in the previous app we will be showing a list of articles from stored in an array.

By pressing one of the buttons in the top bar you can switch between a grid layout containing large images, and a list layout with smaller images and text.

There is a lot more to Vue.js than what we’ve showcased in these examples. The library also offers animations, custom components and all sorts of other features. We recommend you check out the excellent official documentation which is full of information and helpful snippets.

Having troubles deciding whether Vue.js is the right library for your project? The following links will be of great help to you:

  • An official, detailed comparison with other frameworks – here.
  • TodoMVC – a website where the same app is recreated with many different frameworks.
  • Our articles where we’ve done similar examples using React and Angular.js.
