Defining a basic plugin that satisfies the minimum behaviour:
defmodule MyPlugin do
@behaviour Oban.Plugin
use GenServer
@impl Oban.Plugin
def start_link(opts) do
GenServer.start_link(__MODULE__, opts, name: opts[:name])
end
@impl Oban.Plugin
def validate(opts) do
if is_atom(opts[:mode])
:ok
else
{:error, "expected opts to have a :mode key"}
end
end
@impl GenServer
def init(opts) do
case validate(opts) do
:ok -> {:ok, opts}
{:error, reason} -> {:stop, reason}
end
end
