Thanks to the kind folks in the Mozilla PDF.js project we've put together a simple PDF viewing (via PDF.js) and annotating (via Hypothes.is) web app.

Clone this repo, then...

cd pdf.js+hypothes.is
python -m SimpleHTTPServer
# if you're on a Mac, do...
open http://localhost:8000/web/viewer.html
# if you're not, open your browser to that URL

The sample PDF should render and Hypothes.is comment bubble icon should be visible in the top right corner.

The viewer.html file supports a file query parameter, so requesting a different PDF hosted under this same domain, looks like this:

http://localhost:8000/web/viewer.html?file=%2Fyourpdf.pdf

%2F is the URL escaped form of /--so this assumes you have a yourpdf.pdf file hosted at http://localhost:8000/

Loading PDF's from other URL's will require the use of a CORS Proxy ...sadly.

1. Click the comment bubble icon in the top right.
2. Click the "Sign in" link.
3. Sign in or click the "Create an account" tab.
4. Annotate!
