How to debug the code when running a small program in uniapp

UniApp is a cross-platform development framework that supports the use of Vue.js to develop small programs, H5, App and other applications. For developers, UniApp is equivalent to a revolutionary innovation that "writes code once and runs on multiple terminals". In UniApp, we can use a set of codes to quickly develop multi-terminal applications and improve development efficiency. However, when developing the UniApp applet, we will inevitably encounter some problems and need to debug the code. Below, we will introduce how to debug the UniApp applet code.

First, we need to open the UniApp applet. After opening the mini program, we need to enter the developer tools, select the project where the mini program is located, and then enter the debugging mode of the mini program.

Next, we need to debug the code. Code debugging in the UniApp applet is similar to code debugging in Vue.js. We can use the developer tools provided in the Chrome browser to debug. The specific steps are as follows:

Step 1: In the developer tools, find the "Debugger" tab.

Step 2: After entering the "Debugger" tab, first press F1, check "Enable page debugging", then press Ctrl Shift I or select "Developer Tools" in the developer tools --"Page" --"Debug Vue.js".

Step 3: After the "Vue.js DevTools" mark appears on the page, we can happily debug the code! We can view the DOM structure of the page through the "Elements" panel, and we can also execute various debugging commands through the "Console" panel.

In addition to using the Chrome browser for debugging, the UniApp applet also provides some tools to help us debug. For example, we can use the console.log() statement in the code to print logs to better understand the running status of the program. UniApp's debugging tools can also prompt us when errors occur in the code, helping us quickly locate the problem.

In short, in order to better develop the UniApp applet, we need to master the method of code debugging, and have the courage to face problems when encountering them, so that we can achieve good development results in the project.
