Incompatibility with recent versions of pdfjs

[jeromesimeon]

Bug Report 🐛

Recent versions of pdfs do not include es5 build files anymore, which is inconsistent with how we import the library in the markdown-pdf package:

markdown-transform/packages/markdown-pdf/src/ToCiceroMark.js

Line 20 in e9eddfb

let pdfjsLib = require('pdfjs-dist/es5/build/pdf.js');

This means importing the markdown-pdf library may result in failures.

Expected Behavior

We should be able to import the markdown-pdf package without error.

Current Behavior

Context (Environment)

• We list the dependency using a ^ semver here:

  markdown-transform/packages/markdown-pdf/package.json

  Line 89 in e9eddfb

  "pdfjs-dist": "^2.7.570",

• The latest version of pdfjs-dist is 2.8.335 which is compatible with ^2.7.570
• The content of 2.8.335 does not include an es5 directory anymore. See content in the attached file.

Suggested fix

• Import pdfjs-dist/build/pdf.js rather than pdfjs-dist/es5/build/pdf.js
