Reasons and solutions why uniapp cannot use plus directly

With the rapid development of mobile Internet, more and more developers choose to use multi-terminal development frameworks to reduce development costs and improve development efficiency. As a high-performance, multi-terminal unified packaging framework, uniapp has received more and more attention and use.

However, when using uniapp for development, some developers will encounter some problems, such as being unable to use the plus module directly. Let's discuss the reasons why uniapp cannot directly use the plus module and how to solve this problem.

1. Why can’t uniapp use the plus module directly?

Before answering this question, we need to first understand the principle of uniapp and the technology stack it uses. uniapp is essentially a cross-end development framework based on Vue.js syntax, using a series of technology stacks including Vue.js, Webpack, node.js and mini program native extensions. Due to some limitations, uniapp cannot directly use js native web API and other platform-specific APIs like traditional Vue.js applications. uniapp only provides some specific cross-end APIs to fulfill this cross-end requirement.

For H5 and mini programs, the code written by uniapp is directly compiled into native JavaScript and run. You can directly use the js native web API or specific mini program API; but for the App side, due to the need to access some of the native system capabilities, so you need to use the plus.js bridge provided by development tools such as HBuilderX for access to achieve the same experience as native development.

Therefore, we can analyze why the plus module cannot be used directly based on the principle. Because of the packaging method of uniapp, some native capabilities cannot be directly accessed. The plus module is such a capability.

2. How to use the plus module?

Since the plus module cannot be used directly, what should we do? Here are two feasible solutions for your reference.

1. Use the plus module through the uniapp plug-in (uni-modules)

uni-modules is the compatibility of uniapp with all dependent libraries of npm. This method can make uniapp compatible with npm. Native JavaScript library. You can import the required uni-modules package in HBuilderX, similar to the traditional npm package, and you can access the plus module. For example, we can use the plus positioning module by importing the uni-geolocation custom component package.

2. Direct access to the plus module through uni-app-plus

uni-app-plus is an open source project based on uni-app, which enables uni-app to support direct use of plus modules, etc. Native module. It can automatically convert the JS API call that comes with uni-app into the JS API that plus can call, thereby directly calling the plus module. During use, just download the plug-in and integrate it into the project.

Summary

Through the above introduction, I believe everyone has a rough understanding of why uniapp cannot directly use the plus module and how to solve this problem. In general, the cross-end advantages of uniapp are still very prominent. With the help of open source projects such as uni-modules and uni-app-plus, cross-end development tasks can be completed more conveniently and efficiently. Therefore, you need to continue to learn and practice during use. Think to complete better projects.
