javascript - 使用 Rollup 解决 woff 导入问题

Question

我正在尝试使用 Rollup.js 捆绑一个主题包。该主题包括一些全局样式，最相关的@font-face。我正在导入我的字体，并打算通过 styled-components injectGlobal 注入(inject)它们。

当我尝试 bundle 时，Rollup 塞满了字体文件。我的假设是 Webpack 和 Rollup 可以互换使用，不是吗？

做这样的事情的正确方法是什么？

控制台错误:

{ SyntaxError: /Users/****/sites/vz-react/packages/Theme/fonts/NeueHaasGroteskDisplayBold.woff: Unexpected character '' (1:4)

globalStyles.js:

import NeueHassGroteskDisplayBold from '../fonts/NeueHaasGroteskDisplayBold.woff';
import NeueHassGroteskDisplay from '../fonts/NeueHaasGroteskDisplay.woff';
import NeueHassGroteskText from '../fonts/NeueHaasGroteskText.woff';
import NeueHassGroteskTextBold from '../fonts/NeueHaasGroteskTextBold.woff';

const injectGlobalStyles = () => `
  * {
    box-sizing: border-box;
  }

  *:focus {
    outline: #000 dotted 1px;
    outline-offset: 1px;
  }

  body {
    padding: 0;
    margin: 0;
  }

  @font-face {
    font-family: 'NHGDisplay';
    src: url(${NeueHassGroteskDisplayBold}) format("woff");
    font-weight: bold;
    font-style: normal;
  }

  @font-face {
    font-family: 'NHGDisplay';
    src: url(${NeueHassGroteskDisplay}) format("woff");
    font-weight: normal;
    font-style: normal;
  }

  @font-face {
    font-family: 'NHGText';
    src: url(${NeueHassGroteskText}) format("woff");
    font-weight: normal;
    font-style: normal;
  }

  @font-face {
    font-family: 'NHGText';
    src: url(${NeueHassGroteskTextBold}) format("woff");
    font-weight: bold;
    font-style: normal;
  }
`;

export default injectGlobalStyles;

另一种方法是使用 rollup-plugin-url 将字体文件捆绑为 base64 字符串。 :

// rollup.config.js

import url from 'rollup-plugin-url'

export default {
  // ...
  plugins: [
    // ...
    url({
      // by default, rollup-plugin-url will not handle font files
      include: ['**/*.woff', '**/*.woff2'],
      // setting infinite limit will ensure that the files 
      // are always bundled with the code, not copied to /dist
      limit: Infinity,
    }),
  ],
  // ...
}

然后照常导入它们:

// some-file.js

import { createGlobalStyle } from 'styled-components'
import MyFontWoff from '../fonts/my-font.woff'

const GlobalStyle = createGlobalStyle`
  @font-face {
    font-family: 'MyFont';
    src: url(${MyFontWoff}) format('woff');
    font-weight: normal;
    font-style: normal;
  }
`
