Mainly includes data cache, file cache, page cache, cache update, etc. Detailed introduction: 1. Data caching: Mini programs can store data locally so that they can be directly read and updated when needed, without the need to obtain it from the server every time. This caching method can reduce the burden on the server and improve the performance and response speed of the mini program; 2. File caching: the mini program can save some commonly used files or resources locally, such as pictures, videos, audios, etc., to reduce the impact on the server. and network access times, improve the response speed and user experience of the mini program, etc.
Operating system for this tutorial: Windows 10 system, Dell G3 computer.
The caching mechanisms of mini programs mainly include the following:
- Data caching: mini programs can store data locally so that they can be directly read and updated when needed. Instead of getting it from the server every time. This caching method can reduce the burden on the server and improve the performance and response speed of the mini program.
- File caching: The mini program can save some commonly used files or resources locally, such as pictures, videos, audios, etc., to reduce the number of visits to the server and network and improve the response speed and user experience of the mini program. .
- Page caching: The applet can save the page content locally so that the page content can be directly rendered the next time you visit without reloading the page. This caching method can improve the response speed and user experience of the mini program.
- Cache update: The applet can regularly update the data and files in the cache to ensure the latestness and accuracy of the cached data. At the same time, the applet also needs to handle cache update conflicts and synchronization issues to ensure data consistency between multiple devices or users.
In the caching mechanism of the mini program, you need to pay attention to the following points:
- Cache strategy: The mini program needs to choose an appropriate caching strategy based on actual needs and business scenarios. For example, comprehensive considerations should be made based on factors such as data type, access frequency, and data size.
- Cache invalidation: In order to ensure the correctness and integrity of the data, the mini program needs to regularly clear expired or invalid cache data and update the data in the cache in a timely manner.
- Cache capacity: Mini programs need to reasonably control the cache capacity to avoid taking up too many memory resources due to excessive cache capacity, resulting in reduced performance of the mini program.
- Cache security: Mini programs need to take some security measures to protect the security and privacy of cached data, such as encrypted storage, access control, etc.
