uniapp compiles small programs too slowly

With the rapid development of the Internet, more and more people are beginning to use mini programs to conduct business and provide services. Mini programs have the advantages of lightweight and high performance, making them widely used in various fields. As a cross-platform framework, uniapp can easily develop small programs, so that many developers no longer worry about compatibility with different platforms. However, when using uniapp to compile small programs, many developers will encounter a common problem, that is, the compilation speed is too slow. This article will analyze the reasons why uniapp compiles small programs too slowly and provide feasible solutions.

1. The framework version cannot be updated in time

As an open source cross-platform framework, uniapp usually fixes some problems and adds new features as the version is updated. However, some developers may lock the framework version at an earlier version because they are worried that the update will affect the normal operation of the project, which leads to the problem of slow compilation speed.

Solution: Regularly upgrade the uniapp framework version. When the project is updated, you can choose according to the project needs. Of course, you need to back up the project before upgrading to avoid unnecessary trouble.

2. Improper selection of compilation mode

When compiling the uniapp project, there are two compilation modes: development mode and production mode. Development mode does not perform compression and optimization, and the compilation speed is faster; production mode includes compression and optimization, but the compilation speed is slower. Some developers stay in development mode during the development process, which results in a poor project experience and also affects the compilation speed.

Solution: After the project development is completed, be sure to switch the compilation mode to production mode, optimize the code, and compress and optimize the project. This can not only improve the performance of the project, but also speed up the compilation of the project.

3. Compilation cache is not used

Compilation cache is a technical means that can cache the compilation results when compiling the project for the first time, and can skip the compilation results every time in the future. compiled files, thereby increasing compilation speed. However, the uniapp project turns off the compilation cache by default and does not enable it normally. This is also one of the reasons for the slow compilation speed.

Solution: Open the vue.config.js file of the uniapp project, find the "parallel" option, and set it to true. This can enable compilation caching and improve compilation speed.

4. Too many compiled files

If the uniapp project contains a large number of files and components, the compilation process will take a long time. This is also one of the reasons for slow compilation speed.

Solution: You can consider cleaning up unnecessary files in the project and reducing invalid files in the project. At the same time, you can also try to merge the components in the project to reduce the number of components and thereby increase the compilation speed.

5. Optimize picture resources

In the uniapp project, if there are a large number of picture resources, it will also affect the compilation speed of the project. Because image resources need to be compressed and converted before they can be recognized by mini programs, this is also one of the reasons for slow compilation speed.

Solution: For image resources, you can use external links or delayed loading to reduce the size of the image resources in the project. In addition, you can use image compression tools to compress image resources, reduce image size, and increase compilation speed.

Summary:

Although the uniapp framework provides a convenient way to develop small programs, its slow compilation speed has become a common problem faced by many developers. This article analyzes the reasons why uniapp compiles small programs slowly and provides feasible solutions. As long as we adopt these methods, we can speed up the compilation of the uniapp applet and improve the development efficiency of the project.
