来自CDN的deno中的pdfMake

Question

我希望在deno中使用pdfMake，而不是使用CDN行CDNJS或esm.sh在服务器上承载pdfMake文件和vfs_fonts。

在我的app.js文件的to中有以下代码：

import pdfMake from "https://esm.sh/pdfmake"
import * as pdfFonts from "https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.2.4/vfs_fonts.min.js"

但我得到了以下错误：

[!] [#0] starting `deno run -A app.js`
Download https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.2.4/vfs_fonts.js
Download https://deno.land/x/md5/mod.ts
error: Uncaught TypeError: Cannot read properties of undefined (reading 'pdfMake')

    at https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.2.4/vfs_fonts.js:1:21

我不知道如何从CDN导入或加载vfs_fonts。请注意，我的目标是使用CDN获取pdfMake和它的字体。

我已经更改了app.js文件，以便只从CDN加载pdfmake。然后，我将字体从CDN中分别加载到pdfMake对象中：

import pdfMake from "https://esm.sh/pdfmake"

pdfMake.fonts = {
  Roboto: {
    normal: 'https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.66/fonts/Roboto/Roboto-Regular.ttf',
    bold: 'https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.66/fonts/Roboto/Roboto-Medium.ttf',
    italics: 'https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.66/fonts/Roboto/Roboto-Italic.ttf',
    bolditalics: 'https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.66/fonts/Roboto/Roboto-MediumItalic.ttf'
  },
  Merriweather: {
    normal: 'https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.66/fonts/Merriweather/Merriweather-Regular.ttf',
    bold: 'https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.66/fonts/Merriweather/Merriweather-Medium.ttf',
    italics: 'https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.66/fonts/Merriweather/Merriweather-Italic.ttf',
    bolditalics: 'https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.66/fonts/Merriweather/Merriweather-MediumItalic.ttf'
  },
}
