How to speed up vue compilation

Every developer wants to compile code quickly, especially in Vue development, the compilation speed is directly related to product delivery time and user experience. However, the compilation speed of Vue applications can sometimes become extremely slow, especially when the application's code base becomes larger and larger and the configuration becomes more complex, the compilation speed will be even slower. So how to speed up the compilation of Vue? Next, we will share some practical tips to improve Vue compilation speed.

1. Use third-party libraries

The compilation speed of Vue programs can be optimized by using third-party libraries, such as ElementUI or Vuetify and other UI frameworks. Because these frameworks in most cases have some commonly used components built-in, reducing the amount of code for specific components. Of course, this also means that you need to introduce these frameworks into your Vue project, but compared to writing all the code by hand, using third-party frameworks will reduce the compilation workload and speed up compilation.

2. Use CDN

In the Vue project, you can use CDN to introduce libraries such as Vue, Vue-router and Vuex instead of downloading through Node Package Manager (npm) they. A CDN can make a page load faster because it is hosted on multiple servers around the world, and the data is fetched from the nearest server rather than from the origin server. This can reduce the burden of compilation and speed up the running speed of the code.

3. Lazy loading routing

In Vue development, we often define multiple routes, but some routes may not need to be loaded when the user enters the page. At this time, we can use lazy loading of routes, which will only be loaded when needed. This reduces the number of routes on first load, thus speeding up compilation.

4. Avoid unnecessary dependencies

When writing Vue applications, we sometimes use some unnecessary dependencies, such as date formatting libraries such as Moment.js, In fact, Vue's native filter function already provides corresponding date formatting functions. Therefore, before using a dependency, you need to think about whether it is really necessary. Reducing dependencies reduces compilation time and improves performance.

5. Use Webpack or Rollup

Using packaging tools such as Webpack or Rollup can make your Vue application compile faster. These packaging tools package multiple files into a single file, reducing load times and improving performance. In addition, these packaging tools also have some optimization functions, such as compression, removal of comments, and elimination of unused code, which can further reduce the compilation time of Vue programs.

6. Develop a reasonable component division

When encapsulating Vue components, we need to consider the coupling between components. If a component needs to introduce too many dependencies, its compilation speed will slow down. Therefore, components need to be divided reasonably according to business, module or function to reduce the number of dependencies and coupling between components, thereby speeding up compilation.

In short, the compilation speed of Vue applications is directly related to the development efficiency of the project and the user experience. By using third-party libraries, CDN, lazy loading of routes, avoiding unnecessary dependencies, using Webpack or Rollup, and formulating reasonable component divisions, you can effectively improve the compilation speed of Vue applications. It is recommended that developers can optimize for specific projects, choose appropriate methods to speed up compilation, and optimize user experience.
