Why does uniapp initialize main.js

In recent years, as mobile application development has become increasingly popular, the uniapp platform has emerged. uniapp is a progressive cross-platform framework based on the Vue framework. Using uniapp for development can use the same set of code on multiple platforms at the same time, such as WeChat applet, Alipay applet, H5, App and other platforms.

As the entry file of uniapp, we usually perform initial configuration and initialization work in main.js, so why does uniapp initialize main.js?

First, by initializing the main script, developers can manage the project globally and at the page level, including introducing global styles, enabling global functions, configuring request interception and response, etc. Doing so will help improve the overall performance and development efficiency of the project.

Secondly, initializing main.js can also help us better manage the life cycle of the project. Because the application life cycle of uniapp generally refers to the entire life cycle of the entire application from startup to shutdown, and the first js file executed when the application starts is main.js, so through the management of main.js, the entire project can be managed. control its life cycle.

In addition, we can also perform some customized development on uniapp in main.js. For example, introduce some commonly used plug-ins and components and configure them. This can make it more convenient for us to use the uniapp development framework. At the same time, it can also ensure the maintainability and scalability of development and improve our development efficiency.

To sum up, by initializing main.js, we can better manage the overall performance and development efficiency of the uniapp project, better control the life cycle of the uniapp project, and make some personalized customizations development. Therefore, developers must pay attention to the initialization work of main.js, which helps to improve the maintainability and code quality of the code.
