This module keeps track of the build and deploy pipelines.

It will use the given steps from your Mate.Config to either build or deploy your application on the specified servers. The default steps will attempt to sniff whether or not you are in need of the assets pipeline, which uses npm by default.

The pipeline can be updated with custom steps using the configuration file .mate.exs, for example you can add a custom step module with the Mate.Pipeline.Step behaviour.

config :mate,
  steps: fn steps, pipeline ->
    pipeline.insert_before(steps, Mate.Step.CleanBuild, CustomStep)
  end,

  defmodule CustomStep do
    use Mate.Pipeline.Step

    @impl true
    def run(session) do
      IO.puts("Execute my custom code")
      {:ok, session}
    end
  end

You can also use useful commands like local_cmd/2, local_cmd/3, local_script/2, remote_cmd/2, remote_cmd/3, remote_script/2, copy_from/3 and copy_to/3 to interact with the local machine or with the build server in various ways.
