Vue.js is an open source JavaScript framework that helps developers build beautiful web interfaces. The great features of Vue.js are greatly enhanced when used in conjunction with other networking tools. Today, many developers have started using Vue.js to replace Angular and React.js.
So how should developers choose between Angular and React.js?
Below we will introduce and in-depth comparison of these two frameworks.
Vue.js was developed by ex-Googler Evan You and released in 2014, and has now received over 57,000 GitHub stars. Vue is highly recommended by many developers because it is easy to learn. Learning Vue.js should only take a few hours if you have a solid foundation in HTML, CSS and JavaScript.
What makes Vue most attractive to developers is that it's new, lightweight, and has little to no complexity. Vue is not only very flexible and simple, but also very powerful, and also provides two-way data binding capabilities, just like the virtual DOM capabilities of Angular and React.
Vue can help developers build applications in any way they want, something Angular can't do.
Vue.js - Versatile JavaScript Framework
As a cross-platform, highly progressive framework, Vue has become the first choice for many developers who need to create single-page applications. In a typical MVC architecture for developing Web applications, Vue acts as a View, which means it lets the developer see the displayed portion of the data. In addition to the basic features mentioned above, Vue has many other great features.
Let's take a look at these:
1. Easy to use
If you've been using other frameworks, then you can easily use Vue, because Vue's core library is focused on the View layer, and you can easily integrate it with third-party libraries and use it with existing projects.
2. Lightweight
Since Vue is primarily focused on ViewModel or two-way data binding, Vue is lightweight. Vue also has very basic documentation. Vue is used as a View layer, which means that developers can use it as a highlight function in the page, and Vue provides a better choice than a full-scale SPA.
3. Low learning curve
Developers familiar with HTML will find Vue has a low learning curve, while less experienced developers and beginners can learn and understand Vue quickly.
4. Two-way binding
Vue provides the v-model directive (for updating data on user input events) that makes it easy to implement two-way binding on form inputs and structural elements. It can choose the correct way to update elements related to the input type.
5. Virtual DOM
Since Vue is a lightweight virtual DOM implementation based on Snabbdom, the performance of Vue is slightly improved. This is one of the major new features of the virtual DOM, which developers can update directly. When you need to make changes in the actual DOM, you only need to perform such an update function once.
6. HTML Template-Based Syntax
Vue allows developers to directly bind the rendered DOM to the underlying Vue instance data. This is a useful feature because it allows developers to extend basic HTML elements to hold reusable code.
Angular: Dynamic Framework
Angular is a full-featured framework that supports the Model-View-Controller programming structure, ideal for building dynamic single-page web applications.
Developed and supported by Google in 2009, Angular includes a JS codebase based on standard JavaScript and HTML. Angular was originally designed as a tool to enable designers to interact with both the backend and the frontend.
Here are some of the best features of Angular:
1. Model-View-ViewModel（MVVM）
To build client-side web applications, Angular brings together the fundamentals behind the original MVC software design pattern. However, instead of implementing MVC in the traditional sense, Angular implements MVVM or the Model-View-ViewModel pattern .
2. Dependency Injection
Angular comes with a built-in dependency injection subsystem, which makes applications easy to develop and test. Dependency injection allows developers to obtain dependencies by request instead of searching for them. This is very helpful for developers.
3. Test
In Angular, controllers and directives can be unit tested separately. Angular allows developers to have end-to-end and unit test runner setups, which means testing from a user perspective is also possible.
4. Cross-browser compatibility
An interesting feature of Angular is that applications written in the framework work well in multiple browsers. Angular can automatically handle the code required by each browser.
5. Instructions
Angular directives (DOM templates for rendering directives) can be used to create custom HTML markup. These are tags on DOM elements because developers can extend the directive vocabulary and make their own directives, or turn them into reusable components.
6. Deep Linking
Since Angular is primarily used to make single-page applications, it is necessary to take advantage of the Deep Linking feature to load child templates on the same page. The purpose of Deep Linking is to look at the location URL and arrange for it to map to the current state of the page.
Rather than traversing the application from the home page, the Deep Linking feature sets the URL by viewing the state of the page and taking the user to specific content. Deep Linking allows all major search engines to easily search web applications.
Vue.js vs Angular - which is the best?
Exactly which framework is the best - Angular or Vue? Let's delve into the following points:
learning curve
In terms of learning curve, Vue.js is relatively simple to learn and understand, while Angular takes time to get used to. Developers consider both frameworks to be great for projects, but most of the developers prefer to use Vue because Vuex is simpler and scales well when Vuex is added to a project.
Although Vue and Angular share some syntax similarities, such as API and design (this is because Vue was actually inspired from Angular's early development stages), Vue has been working on improving itself in some areas that were difficult for Angular . A developer can build an ad hoc application with Vue.js in a few hours, but this is not possible with Angular.
flexibility
Angular is self-contained, which means your application should be structured in a certain way. Vue is much broader, Vue provides a modular, flexible solution for creating applications.
A lot of times, Vue is thought of as a library rather than a framework. By default, Vue does not include routers, HTTP request services, etc. The developer must install the required "plug-ins". Vue is very flexible and compatible with most libraries that developers want to use.
However, there are developers who prefer Angular because it provides support for the overall structure of their applications. This helps save coding time.
Document Object Model (DOM)
Vue precompiles templates to plain JavaScript with minimal component re-rendering. This virtual DOM allows a lot of optimization, which is the main difference between Vue and Angular. Vue allows for a simpler programming model, while Angular manipulates the DOM in a cross-browser compatible way.
speed/performance
While both Angular and Vue offer high performance, Vue is arguably slightly ahead in speed/performance due to the lighter weight of Vue's virtual DOM implementation.
A simpler programming model enables Vue to provide better performance. Vue can be used without a build system because developers can include it in HTML files. This makes Vue easier to use, which improves performance.
The reason Angular can be slow is that it uses dirty data checking, which means that Angularmonitors keep checking variables for changes.
two-way data binding
Both frameworks support two-way data binding, but Angular's two-way binding is more complex than Vue.js. Two-way data binding in Vue is very simple, and in Angular, data binding is even simpler.
When to choose Vue.js?
If you want the easiest way to make web applications, then you should choose Vue. If your Javascript foundation is not too strong, or have strict development deadlines, Vue will be a good choice.
If your frontend is Laravel then choose Vue. Developers in the Laravel community consider Vue to be their favorite framework. Vue reduces overall processing time by 50% and frees up space on the server.
If you are developing small-scale applications or do not like to be constrained when developing, choose Vue.
If you are familiar with ES5 Javascript and HTML, then use Vue for your projects.
If you want to compile templates in the browser and use its simplicity, using the standalone version of Vue is fine.
Vue's single-file components are perfect if you plan to build performance-critical SPAs or require feature-scoped CSS.
When to choose Angular?
If you need to build large and complex applications, then you should choose Angular because Angular provides a complete and comprehensive solution for client-side application development.
Angular is a good choice for developers looking to deal with client-side and server-side patterns. The main reason developers love Angular is that it enables them to focus on any type of design, whether it's jQuery calls or DOM configuration interference.
Angular is equally suitable for developers creating web applications with multiple components and complex requirements. When you choose Angular, local developers will find it easier to understand application functionality and coding structure.
If you want to choose an existing component in a new project, Angular is also an option as you can just copy and paste the code.
Angular can use two-way data binding to manage synchronization between the DOM and the model. This makes Angular a powerful tool for web application development.
Developers looking to make lighter and faster web applications can take advantage of the MVC structure and separate logic and data components in Angular, which can help speed up the development process.
code comparison
It's fun to analyze the code for Vue and Angular. Code that includes markup, style, and behavior helps developers build efficient and reusable interfaces. In Angular, entities such as controllers and directives are contained in modules, while Vue's modules contain component logic.
Vue components
View.extend({
data: function(){ return {...} },
created: function() {...},
ready: function() {...},
components: {...},
methods: {...},
watch: {...}
//(other props excluded)
});
Angular modules
angular.module(‘myModule’, […]);
Directives in Angular are more powerful.
Vue directives
Vue.directive('my-directive', {
bind: function () {...},
update: function (newValue, oldValue) {...},
unbind: function () {...}
});
Angular directives
myModule.directive('directiveName', function (injectables) {
return {
restrict: 'A',
template: '<div></div>',
controller: function() { ... },
compile: function() {...},
link: function() { ... }
//(other props excluded) };
});
Since Vue.js is inspired by Angular, it also borrows Angular's template syntax. So loops, interpolation and conditionals have very similar syntax for both frameworks.
The code snippet is given below:
Vue interpolation
{{myVariable}}
Angular interpolation
{{myVariable}}
vue loop
<li v-repeat="items" class="item-{{$index}}">
{{myProperty}}
</li>
Angular loop
<li ng-repeat="item in items" class="item-{{$index}}">
{{item.myProperty}}
</li>
Vue conditional
<div v-if="myVar"></div> <div v-show="myVar"></div
Angle condition
<div ng-if="myVar"></div> <div ng-show="myVar"></div>
Vue.js is coded to make page rendering very easy. In fact, Vue.js is more of a library than a framework because it doesn't provide all the features of Angular. Developers will have to rely on third-party code for Vue.js, while Angular provides features like HTTP request service or routers.
