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

|
## Getting Started
|
||
|
|
|
||
|
|
### Online demo
|
||
|
|
|
||
|
|
+ http://mozilla.github.io/pdf.js/web/viewer.html
|
||
|
|
|
||
|
|
### Browser Extensions
|
||
|
|
|
||
|
|
#### Firefox
|
||
|
|
|
||
|
|
PDF.js is built into version 19+ of Firefox, however two extensions are still
|
||
|
|
available that are updated at a different rate:
|
||
|
|
|
||
|
|
+ [Development Version](http://mozilla.github.io/pdf.js/extensions/firefox/pdf.js.xpi) - This version is updated every time new code is merged into the PDF.js codebase. This should be quite stable but still might break from time to time.
|
||
|
|
+ [Stable Version](https://addons.mozilla.org/firefox/addon/pdfjs) - After version 24 of Firefox is released we no longer plan to support the stable extension. The stable version will then be considered whatever is built into Firefox.
|
||
|
|
|
||
|
|
#### Chrome and Opera
|
||
|
|
|
||
|
|
The Chromium extension is still somewhat experimental but it can be installed two
|
||
|
|
ways:
|
||
|
|
|
||
|
|
+ [Unofficial Version](https://chrome.google.com/webstore/detail/pdf-viewer/oemmndcbldboiebfnladdacbdfmadadm) - *This extension is maintained by a PDF.js contributor.*
|
||
|
|
+ Build Your Own - Get the code as explained below and issue `node make chromium`. Then open
|
||
|
|
Chrome, go to `Tools > Extension` and load the (unpackaged) extension from the
|
||
|
|
directory `build/chromium`.
|
||
|
|
|
||
|
|
The version of the extension for the Opera browser can be found at the [Opera add-ons catalog](https://addons.opera.com/en/extensions/details/pdf-viewer/).
|
||
|
|
|
||
|
|
## Getting the Code
|
||
|
|
|
||
|
|
To get a local copy of the current code, clone it using git:
|
||
|
|
|
||
|
|
$ git clone git://github.com/mozilla/pdf.js.git pdfjs
|
||
|
|
$ cd pdfjs
|
||
|
|
|
||
|
|
Next, you need to start a local web server as some browsers don't allow opening
|
||
|
|
PDF files for a file:// url:
|
||
|
|
|
||
|
|
$ node make server
|
||
|
|
|
||
|
|
You can install Node via [nvm](https://github.com/creationix/nvm) or the
|
||
|
|
[official package](http://nodejs.org). If everything worked out, you can now
|
||
|
|
serve
|
||
|
|
|
||
|
|
+ http://localhost:8888/web/viewer.html
|
||
|
|
|
||
|
|
You can also view all the test pdf files on the right side serving
|
||
|
|
|
||
|
|
+ http://localhost:8888/test/pdfs/?frame
|
||
|
|
|
||
|
|
## Building PDF.js
|
||
|
|
|
||
|
|
In order to bundle all `src/` files into two productions scripts and build the generic
|
||
|
|
viewer, issue:
|
||
|
|
|
||
|
|
$ node make generic
|
||
|
|
|
||
|
|
This will generate `pdf.js` and `pdf.worker.js` in the `build/generic/build/` directory.
|
||
|
|
Both scripts are needed but only `pdf.js` needs to be included since `pdf.worker.js` will
|
||
|
|
be loaded by `pdf.js`. If you want to support more browsers than Firefox you'll also need
|
||
|
|
to include `compatibility.js` from `build/generic/web/`. The PDF.js files are large and
|
||
|
|
should be minified for production.
|
||
|
|
|
||
|
|
## Learning
|
||
|
|
|
||
|
|
You can play with the PDF.js API directly from your browser through the live
|
||
|
|
demos below:
|
||
|
|
|
||
|
|
+ Hello world: http://jsbin.com/pdfjs-helloworld-v2/edit#html,live
|
||
|
|
+ Simple reader with prev/next page controls: http://jsbin.com/pdfjs-prevnext-v2/edit#html,live
|
||
|
|
|
||
|
|
The repo contains a hello world example that you can run locally:
