Hosting Fonts on Heroku with Cloudfront

[Brandon Hilkert]

I have a Rails 4 app that I'm hosting on Heroku. I'm using the passenger so all my assets are getting cache-control headers. However. I'm using Cloudfront as an asset CDN, so when fonts are downloaded from an external URL for Firefox, i get an error b/c there's not Access-Control-Allow-Origin headers. I added the following to my config/application.rb:

    config.action_dispatch.default_headers = {

      'X-Frame-Options' => '',

      'Access-Control-Allow-Origin' => '*',

      'Access-Control-Request-Method' => '*'

    }

However, b/c the assets are being served by the downloaded version of Nginx, those headers are integrated and the asset requests never make it to the Rails app.

Is there a way to configure headers for nginx in the Passenger gem?

[Brandon Hilkert]

Any thoughts on this?

Brandon, 

I am facing the same problem. 

It seems though that there is no way to disable nginx from serving static assets. https://groups.google.com/forum/#!searchin/phusion-passenger/static$20files$20/phusion-passenger/C_niqzWeFHM/BMiOlzTNyeMJ

That's quite a bummer.

You can solve this by preventing Heroku from precompiling your
assets[1], and then serving assets from the Rails app[2]. This way
your assets will not be served through Nginx.

[1] Create a file public/assets/manifest.yml to prevent Heroku from
precompiling your assets. See
https://devcenter.heroku.com/articles/rails-asset-pipeline#compiling-assets-locally
[2] Enable config.serve_static_assets. See
https://devcenter.heroku.com/articles/rails-4-asset-pipeline#serve-assets

To me, hosting assets from Nginx was one of the benefits of using Passsenger on Heroku. If I wanted to serve assets from the application, I could just use unicorn (which is what I ended up doing).

In the near future, a method will be provided to customize the Nginx
config file directly in order to set headers for static assets. For
now, this is the way to go.

Thanks for these useful information Hongli Lai.

Is there a way we could test using the version 4.0.39 and have a config file example?

[Chen Tom]
