Introduction

Performance and User Experience

Why Performance Optimization Matters

The relationship between performance and user experience in mini-programs is inseparable. Users may encounter issues such as slow loading, laggy scrolling, and unresponsive interactions while using mini-programs. These issues are all related to the performance of the mini-program. Ultimately, performance issues are user experience issues. If not addressed properly, they can hinder normal usage and even lead users to exit the mini-program.

As mini-programs evolve with more pages and increasingly complex functionalities, performance issues become more prominent. While developing mini-programs, developers should not only focus on implementing features but also invest sufficient effort in optimizing the performance of the mini-program to ensure a good user experience.

How to Perform Performance Optimization

Broadly speaking, performance optimization for mini-programs can be divided into two main themes: Startup Performance and Runtime Performance. "Startup performance" ensures that users can open and see the content of the mini-program faster, while "runtime performance" ensures smooth usage of the mini-program's features. Apart from its functionalities, the excellent performance resulting in a good user experience is crucial for retaining users.

Mini-programs' frameworks combine technologies from both web development and client development and have undergone further innovations. Therefore, some performance optimization methods used in web development are also applicable to mini-programs, such as cache utilization, network request optimization, code compression, and more. Additionally, due to the characteristics of the mini-program technology framework, there are also some special performance optimization methods in mini-program development.

When performing performance optimization, developers can refer to the optimization guides in this chapter and utilize some debugging tools and performance data provided by mini-programs.
