## Overview
Example to demonstrate PDF.js library usage with webpack.
## Getting started
Build project and install the example dependencies:
$ node make dist
$ cd examples/webpack
$ npm install
To build webpack bundles, run `node_modules/.bin/webpack`. If you are running
a web server, you can observe the build results at
http://localhost:8888/examples/webpack/index.html
See main.js and webpack.config.js files. Please notice that PDF.js packaging
requires 'entry' loader.
