View Source Oban.Config (Oban v2.17.0)

The Config struct validates and encapsulates Oban instance state.

Typically, you won't use the Config module directly. Oban automatically creates a Config struct on initialization and passes it through to all supervised children with the :conf key.

To fetch a running Oban supervisor's config, see Oban.config/1.

new(opts)

View Source 
@spec new([Oban.option()]) :: t()

Generate a Config struct after normalizing and verifying Oban options.

See Oban.start_link/1 for a comprehensive description of available options.

Example

Generate a minimal config with only a :repo:

Oban.Config.new(repo: Oban.Test.Repo)

validate(opts)

View Source 
@spec validate([Oban.option()]) :: :ok | {:error, String.t()}

Verify configuration options.

This helper is used by new/1, and therefore by Oban.start_link/1, to verify configuration options when an Oban supervisor starts. It is provided publicly to aid in configuration testing, as test config may differ from prod config.

Example

Validating top level options:

iex> Oban.Config.validate(name: Oban)
:ok

iex> Oban.Config.validate(name: Oban, log: false)
:ok

iex> Oban.Config.validate(node: {:not, :binary})
{:error, "expected :node to be a binary, got: {:not, :binary}"}

iex> Oban.Config.validate(plugins: true)
{:error, "invalid value for :plugins, expected :plugins to be a list, got: true"}

Validating plugin options:

iex> Oban.Config.validate(plugins: [{Oban.Plugins.Pruner, max_age: 60}])
:ok

iex> Oban.Config.validate(plugins: [{Oban.Plugins.Pruner, max_age: 0}])
{:error, "invalid value for :plugins, expected :max_age to be a positive integer, got: 0"}
