cloudxtreme/insight2png

Creates shareable PNGs of ThinkUp insights

Requirements:

• slimerjs
• xvfb (apt-get install xvfb)

Run:

xvfb-run slimerjs server.coffee

Point browser to:

http://localhost:8080/insight.png?url=<full_url_of_insight>

And get an image.

Fun:

That's right, there's fun, too! There's a bookmarklet to generate the image from an insight permalink. Unfortunately you can't embed javascript links in GitHub, but you can get it here.

Develop

I had to move insight2png.coffee to a src dir and compile it to js b/c slimer's coffeescript compiler wasn't handling the new object-ified version of insight2png. If you're developing, just run ./watch while and edits to insight2png.coffee in the src dir will compile to insight2png.js.

Troubleshooting

For newer versions of slimerjs and phantomjs, need to run with flag --ssl-protocol=any

phantomjs|slimerjs --ssl-protocol=any server.js

I'm not sure why this is, but it seems to be specific to ThinkUp's SSL setup, because it's not necessary for all SSL, e.g., https://google.com.
