This patch proposes removing the `browserify` example for the following reasons: - The last `browserify` release was almost two years ago, according to both https://github.com/browserify/browserify/releases and https://www.npmjs.com/package/browserify?activeTab=versions - The project no longer seems to be actively maintained, since so far this year there's only been *a single* (seemingly trivial) patch merged; see https://github.com/browserify/browserify/commits/master - Because of the previous points `browserify` doesn't support modern and up-to-date JavaScript features, as evident from e.g. issue 14731 and multiple issues found in https://github.com/browserify/browserify/issues - Our `browserify` example is most likely not very commonly used, judging by the very low volume of issues/PRs related to it. Looking at the `git` history of that example the only changes have been lint- or maintenance-related.[1] - Providing an example for a framework that's no longer actively maintained doesn't seem like a good idea in general, since we probably don't want to steer users towards using (possibly) older frameworks. - Given that we've never used `browserify` in the PDF.js project, it's also quite difficult to provide support for the example. --- [1] It's interesting to compare with the `webpack` example, since that's generated both issues *and* also PRs (for missing features) from users. |

PDF.js 
PDF.js is a Portable Document Format (PDF) viewer that is built with HTML5.
PDF.js is community-driven and supported by Mozilla. Our goal is to create a general-purpose, web standards-based platform for parsing and rendering PDFs.

Getting Started
Online demo
Please note that the "Modern browsers" version assumes native support for
features such as optional chaining, nullish coalescing,
and private class fields/methods.
-
Modern browsers: https://mozilla.github.io/pdf.js/web/viewer.html
-
Older browsers: https://mozilla.github.io/pdf.js/legacy/web/viewer.html
Browser Extensions
Firefox
PDF.js is built into version 19+ of Firefox.
Chrome
- The official extension for Chrome can be installed from the Chrome Web Store. This extension is maintained by @Rob--W.
- Build Your Own - Get the code as explained below and issue
gulp chromium. Then open Chrome, go toTools > Extensionand load the (unpackaged) extension from the directorybuild/chromium.
Getting the Code
To get a local copy of the current code, clone it using git:
$ git clone https://github.com/mozilla/pdf.js.git
$ cd pdf.js
Next, install Node.js via the official package or via nvm. You need to install the gulp package globally (see also gulp's getting started):
$ npm install -g gulp-cli
If everything worked out, install all dependencies for PDF.js:
$ npm install
Finally, you need to start a local web server as some browsers do not allow opening
PDF files using a file:// URL. Run:
$ gulp server
and then you can open:
Please keep in mind that this requires a modern and fully up-to-date browser; refer to Building PDF.js for non-development usage of the PDF.js library.
It is also possible to view all test PDF files on the right side by opening:
Building PDF.js
In order to bundle all src/ files into two production scripts and build the generic
viewer, run:
$ gulp generic
If you need to support older browsers, run:
$ gulp generic-legacy
This will generate pdf.js and pdf.worker.js in the build/generic/build/ directory (respectively build/generic-legacy/build/).
Both scripts are needed but only pdf.js needs to be included since pdf.worker.js will
be loaded by pdf.js. The PDF.js files are large and should be minified for production.
Using PDF.js in a web application
To use PDF.js in a web application you can choose to use a pre-built version of the library
or to build it from source. We supply pre-built versions for usage with NPM and Bower under
the pdfjs-dist name. For more information and examples please refer to the
wiki page on this subject.
Including via a CDN
PDF.js is hosted on several free CDNs:
- https://www.jsdelivr.com/package/npm/pdfjs-dist
- https://cdnjs.com/libraries/pdf.js
- https://unpkg.com/pdfjs-dist/
Learning
You can play with the PDF.js API directly from your browser using the live demos below:
More examples can be found in the examples folder. Some of them are using the pdfjs-dist package, which can be built and installed in this repo directory via gulp dist-install command.
For an introduction to the PDF.js code, check out the presentation by our contributor Julian Viereck:
