error-handling

Error handling

Methods come in an assertive and a non-assertive form, for example the Wiki.Action.get() method returns an {:ok, ...} or a {:error, ...} tuple, and the Wiki.Action.get!() method raises an error directly.

configuration

Configuration

Configuration variables (TODO: refactor away from config) under the :mediawiki_client application will override the built-in adapters.

  • :ores_endpoint - API endpoint for Wiki.Ores.
  • :tesla_adapter - Defaults to Tesla.Adapter.Hackney, a stable client which performs certificate validation.
  • :user_agent - Sent in request headers, defaults to mediawiki_client_ex/<version>...

For example:

config :mediawiki_client,
  # HTTP client to use for EventStreams.  Defaults to `HTTPoison`.
  eventsource_adapter: Wiki.Tests.HTTPoisonMock,
  # API endpoint for `Wiki.EventStreams`.  Defaults to 
  eventstream_endpoint:
  tesla_adapter: Wiki.Tests.TeslaAdapterMock,
  ores_endpoint: "https://ores.test/v3/scores/",
