vue

What is vue?

Vue.js is a progressive JavaScript framework used for building user interfaces and single-page applications. It is designed to be incrementally adoptable, meaning that it can be used for more than just the interface layer of an application. Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

What are vue's main functionalities?

Reactive Data Binding

Vue.js offers a reactive and composable data binding system. When the state of the application changes, the view automatically updates to reflect the new state.

{"html": "<div id='app'>{{ message }}</div>", "javascript": "var app = new Vue({ el: '#app', data: { message: 'Hello Vue!' } })"}

Components

Vue allows developers to build encapsulated and reusable components, which can have their own state and methods. These components can be composed to build complex user interfaces.

{"javascript": "Vue.component('todo-item', { props: ['todo'], template: '<li>{{ todo.text }}</li>' })"}

Directives

Vue provides a set of built-in directives such as v-if, v-for, v-bind, and v-on, which offer functionality to HTML templates, allowing for declarative rendering and handling of user interactions.

{"html": "<p v-if='seen'>Now you see me</p>", "javascript": "new Vue({ el: '#app', data: { seen: true } })"}

Transition Effects

Vue has a transition system that can apply automatic transition effects when elements are inserted, updated, or removed from the DOM. This feature allows for adding interactive and engaging animations to the UI.

{"html": "<transition name='fade'><p v-if='show'>Hello Vue!</p></transition>", "javascript": "new Vue({ el: '#app', data: { show: true } })"}

Vuex for State Management

For larger applications, Vue can be used with Vuex, a state management pattern and library that helps manage state outside of Vue components for more complex applications.

{"javascript": "const store = new Vuex.Store({ state: { count: 0 }, mutations: { increment: state => state.count++ } })"}

Vue Router for Single Page Applications

Vue Router is the official router for Vue.js, which makes it easy to build single-page applications with Vue by allowing different views to be mapped to different paths.

{"javascript": "const router = new VueRouter({ routes: [{ path: '/foo', component: Foo }, { path: '/bar', component: Bar }] })"}

Other packages similar to vue

react

React is a JavaScript library for building user interfaces, maintained by Facebook. It focuses on a component-based architecture like Vue but uses a different syntax called JSX for combining markup with JavaScript. React also has a larger ecosystem and more extensive community support.

angular

Angular is a platform and framework for building single-page client applications using HTML and TypeScript. It is maintained by Google and offers a comprehensive solution with a wide range of features out of the box, including dependency injection, templating, AJAX handling, and more. It is considered to be more opinionated and has a steeper learning curve compared to Vue.

svelte

Svelte is a relatively new framework that shifts much of the work to compile time, producing highly optimized vanilla JavaScript at the end. Unlike Vue, which updates the DOM in response to state changes, Svelte writes code that surgically updates the DOM when the state of the app changes.

ember

Ember.js is an opinionated framework for building ambitious web applications. It provides a strong convention-over-configuration philosophy and comes with its own router and state management solutions. Ember is known for its powerful CLI and is often compared to Angular in terms of its all-in-one approach.

README

CSP compliant build

This is the CSP-compliant build of Vue.js that does not use new Function() for expression evaluation. Note there's an additional limitation compared to the normal build: you cannot use any globals in expressions (e.g. Date, parseInt etc.).

Intro

Vue.js is a library for building interactive web interfaces. It provides data-reactive components with a simple and flexible API. Core features include:

• Two-way data binding
• Plain JavaScript objects as reactive models
• Component-oriented development style

Note that Vue.js only supports ES5-compliant browsers (IE8 and below are not supported). To check out live examples and docs, visit vuejs.org. You can also start with this excellent screencast series on Laracasts.
