# 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.

See https://github.com/mozilla/pdf.js for learning and contributing.

Update the main, and pdfjs-dist, README to also include recent ECMAScript features This adds "optional chaining" and "nullish coalescing" to the list of features needed when using the modern, i.e. non-translated/non-polyfilled, build of the PDF.js library. 2021-01-20 01:41:50 +09:00			`For usage with older browsers or environments, without support for modern`
Add support for modern ECMAScript `class` features 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". 2021-10-17 20:30:09 +09:00			features such as e.g. `async`/`await`, `ReadableStream`, optional chaining,
