This buildpack is meant to be used with the Heroku Buildpack for Elixir. When deploying Phoenix apps to Heroku, static assets will need to be compiled. This buildpack sees to it that static assets are compiled and that a corresponding asset manifest is generated.

phoenix_static_buildpack.config file in your app's root dir if you want to override the defaults. The file's syntax is bash.
If you don't specify a config option, then the default option from the buildpack's
phoenix_static_buildpack.config file will be used.
Here's a full config file with all available options:
# Clean out cache contents from previous deploys clean_cache=false # We can change the filename for the compile script with this option compile="compile" # Add the config vars you want to be exported here config_vars_to_export=(DATABASE_URL) # We can set the version of Node to use for the app here node_version=5.3.0 # We can set the version of NPM to use for the app here npm_version=2.10.1 # We can set the path to phoenix app. E.g. apps/phoenix_app when in umbrella. phoenix_relative_path=. # Remove node and node_modules directory to keep slug size down if it is not needed. remove_node=false
By default, Phoenix uses
brunch and recommends you to use
mix phoenix.digest in production. For that, we have a default
compile shell script which gets run after building dependencies and
just before finalizing the build. The
compile file looks like this:
info "Building Phoenix static assets" brunch build --production mix phoenix.digest
To customize your app's compile hook, just add a
compile file to your app's root directory.
compile is just a shell script, so you can use any valid
bash code. Keep in mind you'll have
access to your
mix. This means that if you're using a Node build tool other than
brunch, you can just do something like:
# app_root/compile gulp build:dist mix phoenix.digest
compile overrides the default one. :)
This buildpack is only necessary when you need to compile static assets during deploys. You will not need this buildpack if you are using Phoenix only as a REST API.
Do I need
