What are the specifications for applet development?

Directory structure:

Use a clear directory structure to organize code files, such as placing pages, components, styles, and resource files in different directories.

Follow the directory structure specified by the applet framework, for example, place pages in the pages directory and components in the components directory.

File name:

Use meaningful file names to describe the purpose and function of the file.

Follow the file naming specification specified by the applet framework, for example, the page file uses the. wxml extension, and the style file uses the. wxss extension.

Style specification:

Use consistent style naming and organization to make style codes easy to read and maintain.

Avoid using overly complex style selectors to improve performance.

Minimize the nesting level of style files to avoid style conflicts and performance problems.

JavaScript specification:

Use clear variable and function names to accurately describe their purposes and functions.

Follow consistent indentation and code style to improve code readability.

Use comments to explain key parts and logic of the code.

API call:

Use the API provided by the applet reasonably to avoid frequent and unnecessary calls.

Reasonably handle asynchronous operations, and use callback functions, promise or async/await to control the process.

Picture and resource management:

Use appropriate picture formats and sizes to reduce applet loading and rendering time.

Try to avoid too many image resources to reduce the size of the package.

Properly use image compression and caching strategies to improve performance and user experience.

Security:

User input is verified and filtered to prevent potential security vulnerabilities.

Reasonably handle user permissions and sensitive information to ensure the security of user data.

These specifications help maintain the consistency, readability, and maintainability of applet code. At the same time, applet development also needs to follow various platforms (such as WeChat applet , Alipay applet) to ensure that the application can pass the review and be released and run on the corresponding platform.
