How to set a global unified font in uniapp

With the popularity of UniApp, more and more developers choose to use it to build cross-platform applications. For many developers, in order to achieve a consistent design across their applications, they need to use a globally consistent font. In this article, we will introduce how to set a global unified font in UniApp.

1. Install font files

To set a global unified font, you first need to install the corresponding font file. You can download font files for free from the Internet, or use your own font files. Just copy the downloaded font file to the "/static/fonts/" directory.

2. Set global styles in App.vue

Before setting the global font, you need to create a style tag in App.vue and define the global style in it. You can use the following code to create a style tag and set a global style:

<style lang="scss">
  @font-face {
    font-family: 'myfont';
    src: url('../static/fonts/myfont.ttf');
  }
  
  .global-font {
    font-family: 'myfont';
    font-size: 16px;
    color: #333;
  }
</style>

In the above code, the "font-family" attribute defines the name of the custom font file, here we name it "myfont". The "src" attribute points to the path of the font file, which should be modified according to your actual situation.

After declaring the font, you can set the global style. Here, we define the "global-font" style to use the same font, size, and color for all elements in the application.

3. Using global fonts in components

Next, you can use global fonts in components. If you want an element to use a global font, just set its class to the defined global style. For example, you can use a global font in the following code:

<template>
  <view class="global-font">这是一个使用全局字体的元素。</view>
</template>

In the above code, we set the class of the "view" element to "global-font", indicating that it will use the class we set in App.vue Defined global font.

4. Set global fonts through Sass variables

If you need to set different fonts according to different platforms, you can use Sass variables to achieve this. In order to use Sass variables, you need to create a Sass file in the "/src" directory and set the global font variable. You can use the following code:

// variables.scss

$global-font-family: 'myfont';

In the above code, we set the variable "$global-font-family", whose value is the global font name we defined.

Now, the above variables can be used in global styles and components. For example, you can use it in a global style using the following code:

// App.vue

<style lang="scss">
  @font-face {
    font-family: #{$global-font-family};
    src: url('../static/fonts/myfont.ttf');
  }

  .global-font {
    font-family: #{$global-font-family};
    font-size: 16px;
    color: #333;
  }
</style>

In the above code, we use the variable "$global-font-family" instead of the font name. This way, you can set the font name once in Sass and then use it across applications.

Setting the font through Sass variables also allows you to use different fonts on different platforms. Just set the fonts you want to use on each platform individually in a variable file.

Conclusion

Setting global fonts in UniApp is simple. Just install the font files and use them in global styles and components. Using Sass variables you can also use different fonts on different platforms. By following the above guidelines, you can easily create a consistent font style for your application.
