Phoenix LiveDebugConsole

This package implements an extension to the error view shown in Phoenix applications, adding a fully-interactive IEx shell. Here's a video of me triggering an error in a Phoenix application and then poking around a little bit using the live debug console:

Installation

1. This package currently requires that your application uses a bleeding edge development build of Phoenix which has phoenixframework/phoenix#4938 applied.

2. Install the package by adding phoenix_live_debug_console to your list of dependencies in mix.exs:

def deps do
  [
    {:phoenix_live_debug_console, "~> 0.1"}
  ]
end

3. Configure the endpoint of your application such that debug_errors and debug_error_handlers are set as follows:

config :my_app, MyAppWeb.Endpoint,
  debug_errors: true,
  debug_banner_hooks: [{PhoenixLiveDebugConsole, :render_console, []}]

Credits

This library was written by Frerich Raabe, however it is really just standing on the shoulders of giants:

• Underthehood is what implements the IEx terminal
• Phoenix LiveDashboard served as an inspiration for developing an extension package which comes with its own assets.
