With ESLint 8 we should now finally be able to start using modern `class` features, see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes/Public_class_fields and https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes/Private_class_fields However, while both ESLint and Acorn now support this, it unfortunately turns out that Escodegen (which we use during building) still lack the necessary support. Looking at https://github.com/estools/escodegen there's not been any updates since last year, and there's also open PRs adding support for these new `class` features. To avoid blocking usage of these `class` features in the PDF.js code-base, in particular *private* fields/methods, this patch thus proposes that we (hopefully temporarily) switch to an `escodegen` fork that has the necessary support; please see https://www.npmjs.com/package/@javascript-obfuscator/escodegen While I have no reason to doubt the security of the `escodegen` fork, this patch nonetheless pins the version number. Furthermore, I've also diffed the output of the two `.js`-files in this forked package against the original files without finding anything that looks immediately "dangerous".

# PDF.js
|
|
|
|
PDF.js is a Portable Document Format (PDF) library that is built with HTML5.
|
|
Our goal is to create a general-purpose, web standards-based platform for
|
|
parsing and rendering PDFs.
|
|
|
|
This is a pre-built version of the PDF.js source code. It is automatically
|
|
generated by the build scripts.
|
|
|
|
For usage with older browsers or environments, without support for modern
|
|
features such as e.g. `async`/`await`, `ReadableStream`, optional chaining,
|
|
nullish coalescing, and private `class` fields/methods; please see the `legacy`
|
|
folder.
