Vue Js Documentation Pdf

Posted on  by admin

You’re browsing the documentation for v2.x and earlier. For v3.x, click here. Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces.

Sample overview

What is Vue.js?

Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable.

Use more WebViewer APIs

The core library is focused on the view layer only, and is easy to pick up and integrate with other libraries or existing projects.

Conditionals and Loops

On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

Relation to Custom Elements

If you’d like to learn more about Vue before diving in, we created a video walking through the core principles and a sample project. If you are an experienced frontend developer and want to know how Vue compares to other libraries/frameworks, check out the Comparison with Other Frameworks.

:page Number - default: 1

The official guide assumes intermediate level knowledge of HTML, CSS, and JavaScript.

:rotate Number - default: 0

If you are totally new to frontend development, it might not be the best idea to jump right into a framework as your first step - grasp the basics then come back!

Initial setup

@password (updatePassword, reason)

  • Prior experience with other frameworks helps, but is not required.
  • The easiest way to try out Vue.js is using the Hello World example. Feel free to open it in another tab and follow along as we go through some basic examples.

@progress Number

Or, you can create an index.html file and include Vue with:.

@loaded

The Installation page provides more options of installing Vue.

@page-loaded Number

Note: We do not recommend that beginners start with vue-cli, especially if you are not yet familiar with Node.js-based build tools.

@num-pages Number

If you prefer something more interactive, you can also check out this tutorial series on Scrimba, which gives you a mix of screencast and code playground that you can pause and play around with anytime.

@error Object

At the core of Vue.js is a system that enables us to declaratively render data to the DOM using straightforward template syntax:.

@link-clicked Number

We have already created our very first Vue app!

Next step

print(dpi, pageList) experimental

  • This looks pretty similar to rendering a string template, but Vue has done a lot of work under the hood.
  • The data and the DOM are now linked, and everything is now reactive.

Declarative Rendering

createLoadingTask(src[, options])

  • How do we know? Open your browser’s JavaScript console (right now, on this page) and set app.message to a different value.

  • You should see the rendered example above update accordingly. Note that we no longer have to interact with the HTML directly. A Vue app attaches itself to a single DOM element (#app in our case) then fully controls it. The HTML is our entry point, but everything else happens within the newly created Vue instance.

    In addition to text interpolation, we can also bind element attributes like this:. Hover your mouse over me for a few seconds to see my dynamically bound title!

    Here we are encountering something new.

  • The v-bind attribute you are seeing is called a directive. Directives are prefixed with v- to indicate that they are special attributes provided by Vue, and as you may have guessed, they apply special reactive behavior to the rendered DOM.

  • Here, it is basically saying “keep this element’s title attribute up-to-date with the message property on the Vue instance.”.

  • If you open up your JavaScript console again and enter app2.message = 'some new message', you’ll once again see that the bound HTML - in this case the title attribute - has been updated.
