Storybook is a tool for UI development. It makes development faster and easier by isolating components. This allows you to work on one component at a time. You can develop entire UIs without needing to start up a complex dev stack, force certain data into your database, or navigate around your application.
Use Storybook to build small atomic components and complex pages in your web application. If it's a UI, you can build it with Storybook. Storybook helps you document components for reuse and automatically visually test your components to prevent bugs.
Extend Storybook with an ecosystem of addons that help you do things like fine-tune responsive layouts or verify accessibility.

If you want to learn more about the component-driven approach that Storybook enables, this site is a good place to start. If you want a guided tutorial through building a simple application with Storybook in your framework and language, our tutorials have your back.
Read on to learn Storybook basics and API! 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.
Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is easy to pick up and integrate with other libraries or existing projects.
Composing with Components
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.
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.
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.
Or, you can create an index.html file and include Vue with:. The Installation page provides more options of installing Vue. Note: We do not recommend that beginners start with vue-cli, especially if you are not yet familiar with Node.js-based build tools.
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.
At the core of Vue.js is a system that enables us to declaratively render data to the DOM using straightforward template syntax:. We have already created our very first Vue app!
Explanation of Different Builds
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.
