WeChat Mini Program Tutorial Mini Program Configuration

WeChat Mini Program—Configuration

The following is the editor’s systematic arrangement of the configuration information of the Mini Program. I hope it will be helpful to developers.

We use the app.json file to globally configure the WeChat applet, determine the path of the page file, window performance, set the network timeout, set multiple tabs, etc.

The following is a simple configuration app.json that contains all configuration options:

{  
 "pages": [  
  "pages/index/index",  
  "pages/logs/index"  
 ],  
 "window": {  
  "navigationBarTitleText": "Demo"  
 },  
 "tabBar": {  
  "list": [{  
   "pagePath": "pages/index/index",  
   "text": "首页"  
  }, {  
   "pagePath": "pages/logs/logs",  
   "text": "日志"  
  }]  
 },  
 "networkTimeout": {  
  "request": 10000,  
  "downloadFile": 10000  
 },  
 "debug": true  
}

app.json configuration item list

Properties

Type

Required

Description

pages Array Yes Set the page path

window Object No Set the window performance of the default page

tabBar Object No Set the performance of the bottom tab

networkTimeout Object No Set the network timeout

debug Boolean No Set whether to enable debug mode

pages

Accepts an array, each item is a string, to specify the mini program by What pages are composed of. Each item represents the [path + file name] information of the corresponding page, and the first item in the array represents the initial page of the mini program. Adding/reducing pages in the mini program requires modifying the pages array.

There is no need to write a file suffix in the file name, because the framework will automatically look for the four files in the path .json, .js, .wxml, and .wxss for integration.

If the development directory is:

pages/  
pages/index/index.wxml  
pages/index/index.js  
pages/index/index.wxss  
pages/logs/logs.wxml  
pages/logs/logs.js  
app.js  
app.json  
app.wxss

, we need to write

{  
 "pages":[  
  "pages/index/index"  
  "pages/logs/logs"  
 ]  
}

window

in app.json to set the status bar of the mini program , navigation bar, title, window background color.

}

tabBar

If our applet is a multi-tab application (there is a tab bar at the bottom of the client window to switch pages), then we can specify the performance of the tab bar through the tabBar configuration item , and the corresponding page displayed when tab switching.

tabBar is an array, and only a minimum of 2 and a maximum of 5 tabs can be configured. The tabs are sorted in the order of the array.

debug

可以在开发者工具中开启 debug 模式，在开发者工具的控制台面板，调试信息以 info 的形式给出，其信息有Page的注册，页面路由，数据更新，事件触发 。 可以帮助开发者快速定位一些常见的问题。

page.json

每一个小程序页面也可以使用.json文件来对本页面的窗口表现进行配置。 页面的配置比app.json全局配置简单得多，只是设置 app.json 中的 window 配置项的内容，页面中配置项会覆盖 app.json 的 window 中相同的配置项。

页面的.json只能设置 window 相关的配置项，以决定本页面的窗口表现，所以无需写 window 这个键，如：

{  
 "navigationBarBackgroundColor": "#ffffff",  
 "navigationBarTextStyle": "black",  
 "navigationBarTitleText": "微信接口功能演示",  
 "backgroundColor": "#eeeeee",  
 "backgroundTextStyle": "light"  
}
