WeChat applet optimization method

1. Improve the loading speed of applets: The loading speed of applets has a great impact on user experience. You can improve the loading speed by reducing file size, merging the same requests, and using CDN.

2. Reduce the number of requests: Too many requests will reduce the performance of the applet. You can use caching, lazy loading and other technologies to reduce the number of requests.

3. Simplify the code: Too much code will slow down the running of the applet. You can simplify the code and improve the performance of the applet by deleting unused code and reducing unnecessary judgments.

4. Optimize pictures: Too large pictures will lead to longer loading time of applets, you can optimize pictures by compressing pictures, using WebP format, etc.

5. Optimize rendering: The performance of applets will be affected when rendering pages. You can improve the performance of applets by optimizing layout and reducing layers.

6. Use sub-package loading: Divide the pages in the applet into multiple packages, which can reduce the time for the first startup of the applet and optimize the performance of the applet at runtime.

7. Data burying point: Through data burying point, you can understand the user behavior and usage of the Mini Program, and optimize it according to the data analysis results.
