What are the pitfalls of uniapp app development?

With the advent of the mobile Internet era, App applications have become an indispensable part of people's daily lives. In recent years, with the continuous development of technology, App development has gradually moved towards cross-platform application development. As a development framework that integrates multiple platforms, Uniapp is favored by more and more developers due to its efficiency, simplicity, and stability. However, some developers also encounter problems when using Uniapp for App development. Encountered some difficulties and pitfalls. This article will introduce in detail some of the pitfalls when Uniapp develops apps.

1. Basic configuration

1. File names must be lowercase: Uniapp has strict regulations on file names. All file names must be lowercase. If the file name contains special characters, Compilation errors may occur.

2. Problems with introducing style sheets: When importing external style sheets, you need to pay attention to the following points:

(1) The file name in the style sheet must be lowercase, otherwise it may Triggers a compilation error;

(2) When using css tools such as less, sass, etc., you need to set minimize to false, otherwise the style sheet will be reduced, causing some styles to become invalid;

(3) The style sheet defined in the style tag in App.vue will not overwrite the style sheets of other pages, and the style needs to be defined in the specific page.

3. Problems with introducing third-party resources: When introducing third-party resources, you need to pay attention to the following points:

(1) You need to check whether the version of the third-party resource meets the requirements. Low will cause incompatibility issues;

(2) You need to check whether third-party resources support introduction in Vue. If not, you need to use uni.scss to introduce them.

2. Pitfalls in development

1. Multi-terminal compatibility issues: Although the Uniapp framework is cross-platform, there are still problems with the compatibility of different platforms. For example, some components in the h5 platform and the mini program platform are different in style and function, and developers need to test and handle them by themselves. Compatibility of each platform needs to be carefully checked before publishing the app.

2. Missing components: Uniapp has relatively few component libraries, but at the same time it needs to consider multi-terminal compatibility issues. This has resulted in many existing component libraries not supporting Uniapp. Developers are kindly requested to Before using a third-party component library, conduct a compatibility test to confirm that the component library can be used normally on multiple platforms.

3. Routing jump problem: When using the uni.navigateTo() method to jump to a page, you need to ensure that the jumped page belongs to the same component. If you want to jump to a page under a different component, you need to use the uni.switchTab() or uni.reLaunch() method.

4. Custom navigation bar problem: When customizing the navigation bar, you need to modify the global configuration file, which may lead to style confusion and other problems. Developers need to carefully check and test navigation bar compatibility and develop different navigation bar styles for different platforms.

5. Image size issue: When using images, you need to pay attention to the size of the image. When an image is distorted or stretched, it's usually because the image size is incorrect. Developers need to adjust according to the size requirements of different platforms.

6. Font problem: Fonts may be different under different platforms, and developers need to test and check under different platforms. You also need to pay special attention to issues such as the version and file format of the font file, otherwise it may cause incompatibility issues.

3. Performance optimization issues

1. JS code compression: Before publishing an application, JS code needs to be compressed, which can improve the speed of application running. You can use tools such as Webpack to compress JS files to reduce file size and improve running speed.

2. Image compression: Using high-definition images will slow down the loading speed of the application and take up more storage space. Images need to be compressed to reduce file size and improve application loading speed.

3. Delete useless code: Before packaging the application, you need to delete useless code to reduce the file size.

4. Caching mechanism: Adding a suitable caching mechanism to the application can help improve the access speed of the application. You can use localstorage technology to cache some data that needs to be accessed frequently.

Summary:

The above are some pitfalls you may encounter when using Uniapp for App development. Through the introduction of this article, I believe that everyone will have a deeper understanding of the problems that may be encountered when developing apps with Uniapp. Developers need to carefully check and test the compatibility, performance and stability of the application, and perform corresponding optimization and testing before the application is released to ensure the quality and user experience of the application. I believe that on the premise that these problems are properly resolved, the Uniapp framework still has very broad application prospects.
