Phoenix Template Engine for Slim

Build Status Hex Version License

Powered by Slime


  1. Add {:phoenix_slime, "~> 0.13.1"} to your deps in mix.exs.
  2. Add the following to your Phoenix config/config.exs:
  config :phoenix, :template_engines,
    slim: PhoenixSlime.Engine,
    slime: PhoenixSlime.Engine,
    slimleex: PhoenixSlime.LiveViewEngine # If you want to use LiveView

An example project can be found at slime-lang/phoenix_slime_example.

Live Reloader

In my_app/config/dev.exs, include the slim and slime extensions in the list of watched files. (Replace APP with your app name.)

# Watch static and templates for browser reloading.
config :my_app, MyApp.Endpoint,
  live_reload: [
    patterns: [


This library also includes two mix tasks:

mix phx.gen.html.slime mix phx.gen.layout.slime

The first task creates a html resource in the same way phx.gen.html does with the exception that all files are .slime files instead of .eex files.

The second task creates a new lib/APP_web/templates/layout/app.html.slime with the exact same content as the app.html.eex file. Do not forget to remove the old app.html.eex file.

Generated files have .slime extension by default. If you prefer .slim, you could add the following line to your config:

config :phoenix_slime, :use_slim_extension, true
