  ## Dependencies

  # Although we use requirements here, the with_lock() function
  # below ensures we only use the locked versions. This is important
  # for two reasons:
  #
  #   1. because we bundle assets from phoenix, phoenix_live_view,
  #      and phoenix_html, we want to make sure we have those exact
  #      versions
  #
  #   2. we don't want users to potentially get a new dependency
  #      when installing from git or as an escript
  #
  # Therefore, to update any dependency, you must call before:
  #
  #     mix deps.unlock foo bar baz
  #
