Phoenix.CodeReloader

A plug and module to handle automatic code reloading.

For each request, Phoenix checks if any of the modules previously compiled requires recompilation via __phoenix_recompile__?/0 and then calls mix compile for sources exclusive to the web directory.

To avoid race conditions, all code reloads are funneled through a sequential call operation.

Summary

Functions

call(conn, opts): API used by Plug to invoke the code reloader on every request
init(opts): API used by Plug to start the code reloader
reload!(endpoint): Reloads code for the current Mix project by invoking the :reloadable_compilers

Functions

call(conn, opts)

API used by Plug to invoke the code reloader on every request.

init(opts)

API used by Plug to start the code reloader.

reload!(endpoint)

Specs

reload!(module) :: :ok | {:error, binary}

Reloads code for the current Mix project by invoking the :reloadable_compilers.

This is configured in your application environment like:

config :your_app, YourApp.Endpoint,
  reloadable_compilers: [:gettext, :phoenix, :elixir]

Keep in mind :reloadable_compilers must be a subset of the :compilers specified in project/0 in your mix.exs.
