Benefits of using vue: 1. Vue is component-based development, which reduces code writing and makes the code easy to understand; 2. Data can be bound in two directions; 3. Compared with the traditional use of hyperlinks to create pages For switching and jumping, Vue uses routing and does not need to refresh the page; 4. Vue is a single-page application. It does not need to obtain all the data and DOM when loading, which improves the loading speed and optimizes the user experience; 5. Vue's third-party components The library is rich, easy to use, and improves development efficiency.

What is Vue.js

Vue is a progressive JavaScript framework for building user interfaces. Unlike other large frameworks, Vue is designed to be applied layer by layer from the bottom up. Vue's core library only focuses on the view layer, which is not only easy to get started, but also easy to integrate with third-party libraries or existing projects. On the other hand, when combined with a modern tool chain and various supporting libraries, Vue is fully capable of providing drivers for complex single-page applications (SPA).

The goal of Vue.js is to enable responsive data binding and composed view components through the simplest possible API.

Vue.js itself is not a comprehensive framework - it only focuses on the view layer. Therefore it is very easy to learn and very easy to integrate with other libraries or existing projects. On the other hand, Vue.js can also power complex single-page applications when used with related tools and support libraries.

Advantages of Vue.js

  • Small size: only 33k after compression;

  • More High operating efficiency: Based on virtual DOM, a technology that can perform various calculations through JavaScript in advance to calculate and optimize the final DOM operation. Since this DOM operation is a preprocessing operation and does not actually operate the DOM, It’s called virtual DOM; [Learning video sharing: vue video tutorial, web front-end video]

  • Two-way data binding: so that developers don’t have to Then operate DOM objects and put more energy into business logic;

  • Rich ecology and low learning cost: There are a large number of mature and stable UIs based on vue.js on the market The framework and components can be used to achieve rapid development; it is friendly to beginners, easy to get started, and has a lot of learning materials;

In fact, aside from some unintelligible official statements, let’s take a simple look Say, in traditional web development, we build projects based on the HTML structure, and then add various special effects functions through jquery or js, and we need to select each element for commands.

These contents can still be dealt with in simple projects or unchanged projects. Once the project changes or the project is large, the code modification will be complicated and cumbersome.

But now with vue, these problems no longer exist. For example, some applications made from a single web page generally involve a lot of data interaction, and applying Vue will greatly reduce the workload.

What are the significant advantages of vue in web development and website production?

1. Data binding: Vue will set the element data according to the corresponding element, and perform real-time binding of data through input boxes, get data and other methods. Data rendering for web pages and applications.

2. Component-based development: Through the module encapsulation of vue, it can split various modules designed in a web development into separate components, and then call the corresponding template components through data binding. , and by passing in parameters at the same time, the development of the entire project can be completed.

What are the benefits of using vue?

  • Vue is component-based development, which reduces code writing and makes the code easy to understand.

  • The most prominent advantage is that data can be bound in two directions.

  • Compared with the traditional use of hyperlinks to switch and jump pages, Vue uses routing without refreshing the page.

  • Vue is a single-page application. It does not need to obtain all the data and DOM when loading, which improves the loading speed and optimizes the user experience.

  • Vue has a rich third-party component library, which is easy to use and improves development efficiency.

1. Responsive performance improvement

1) Diff method optimization

diff algorithm is an inevitable product of virtual DOM technology , it compares the old and new DOM, and then updates the changed DOM on the real DOM. Using vue, when creating a virtual DOM, a static mark will be added based on the content in the DOM. When the data changes, the static marked nodes will be compared, so that the changed DOM can be quickly found.

2) Event listener cache

By default onClick will be regarded as dynamic binding, so its changes will be tracked every time, but because it is the same function, there is no need to track it Changes can be directly cached and reused.

3) ssr rendering

When there is a large amount of static content, the content will be pushed into a buffer as a pure string. Even if there is dynamic binding, it will be sneaked in through template interpolation, which will be much faster than virtual DOM rendering.

2. Code size reduction

The package size is reduced by 41%.

vue has removed some uncommon APIs, such as inline-template, filter, etc., and uses tree-shaking.

Tree Shaking Tree shaking optimization means that when we introduce a module, we do not introduce all the code of this module, but only the code we need.

In vue, tree-shaking is introduced, and all APIs are introduced through ES6 modularization. This allows packaging tools such as webpack or rollup to automatically modify unused APIs when packaging. Perform culling to minimize bundle size.

Initial rendering is 55% faster, and update rendering is 133% faster. The components are introduced on demand, which makes the packaged size smaller, so the project runs faster and smoother!

3. Compilation is optimized

After using static promotion with vue, elements that do not participate in updates will only be created once and can be reused directly during rendering. .

There is no need to create a unique root node in the Fragment template, you can directly place tags and content at the same level. It is equivalent to one less node for nested rendering.

4. Combined API

vue has added a combined API, which is more conducive to maintenance and encapsulation. The code of a functional module will be gathered together to achieve high cohesion and low coupling. Improve code readability and maintainability, and APIs based on function composition better reuse logical code.

5. Better ts support

vue has added the defineComponent function to enable components to better utilize parameter type inference under ts. For example: reactive and ref are very representative.

6. More advanced components

  • vue does not require a root node, and multiple elements or labels can exist side by side.

  • You can add the content in the teleport to any node, which is definitely a boon for deeply nested components.

  • Allowing the program to wait for asynchronous components to render some back-up content allows us to create a smooth user experience.

7. Simple summary:

vue is currently one of the most popular front-end frameworks in China. Vue has improved performance and running speed than others. The frame is much better.

In short, vue is:

  • Make the project faster

  • Make the code less

  • Easier to maintain

  • Let us develop faster and work less overtime
