In which file is the configuration of the uniapp tab located?

When using uni-app to develop small programs, you often need to use tabs. Tabs allow users to easily switch between different pages and improve user experience. So, in uni-app, in which file is the tab configuration located?

The answer is in the pages.json file. pages.json is the file that configures the page in uni-app, which includes the page path, page title bar color, tab and other information. In this file, you can configure the tab through the following code:

"tabBar": {
  "color": "#999",
  "selectedColor": "#007aff",
  "backgroundColor": "#fff",
  "borderStyle": "black",
  "list": [
    {
      "pagePath": "pages/index/index",
      "text": "首页",
      "iconPath": "static/tabbar/home.png",
      "selectedIconPath": "static/tabbar/home-active.png"
    },
    {
      "pagePath": "pages/logs/logs",
      "text": "日志",
      "iconPath": "static/tabbar/logs.png",
      "selectedIconPath": "static/tabbar/logs-active.png"
    }
  ]
}

In the above code, tabBar is the configuration item of the tab. Among them, color is the unselected text color of the tab, selectedColor is the selected text color, backgroundColor is the background color of the tab, borderStyle is the border style of the tab. In the list array, you can configure the path, title, icon and other information of each tab.

It should be noted that if you do not need tabs, you can directly delete or comment out the tabBar configuration item.

In general, the configuration of the tab is very simple, you only need to make the corresponding configuration in the pages.json file. Through the setting of tabs, switching between mini program pages can be made easier and more convenient, improving the user experience.
