following usage instructions results in error

[josh-m-sharpe]

I can't seem to get this running locally - errors below. Is it possible the installation/usage sections are out of date?

More broadly - how are you hosting this for production? On heroku maybe? A section in the README about how to set that up would be much appreciated.

Thanks!

Hi Josh. PhantomJS as a dependency is certainly tricky; I'll have to look into some better docs on getting it installed and running. If I remember correctly I had to do some manual work to get the correct version of https://www.npmjs.com/package/phantomjs-prebuilt for my operating system.

As for production, I run this in heroku using this buildpack to satisfy the phantomjs dependency:

https://github.com/stomita/heroku-buildpack-phantomjs

Have you managed to work around this problem yet?

[josh-m-sharpe]

No - just started playing around with it. I don't have it live yet.

Do you run it along side your app that uses it or do you have a separate app in heroku just for this?

[wheeyls]

In production I run it as a standalone app; it is used to compile CSS for a few different apps.

[josh-m-sharpe]

Ok. Got this running on heroku. And I have my rails app wired up with RailsCriticalCssServer.

if I look in the logs of the critical-css-server I see POST requests being made to it that correspond with me refreshing my rails app. So, that's great. However, they're all status=202, which I think is this line? https://github.com/wheeyls/critical-css-server/blob/master/src/app.js#L33

I've been refreshing for a few minutes now - any ideas what i've missed? How long should it take to process a single page/file ?

Thanks!

[josh-m-sharpe]

One note, I commented out auth_token in the RailsCriticalCssServer config since I wasn't sure what kind of 'auth' that referred to on the node side. I suppose that's fine because it's getting to the 202 line above and not bonking on some 401 auth required.

[wheeyls]

@josh-m-sharpe yeah the critical-css-server doesn't have any auth options by default; when I use this in production I actually route it through an extra middleware that looks for the auth token.

Have you checked the logs on heroku with heroku logs --tail while hitting the server? The worker should be processing the CSS in the background, and reporting any errors to the logs.

Hi @josh-m-sharpe, curious if you ever got this up and running?
