Handles logging of Absinthe-specific events.

Variable filtering

Absinthe can filter out sensitive information like tokens and passwords during logging. They are replaced by "[FILTERED]".

Use the :filter_variables configuration setting for this module. For example:

config :absinthe, Absinthe.Logger,
  filter_variables: ["token", "password", "secret"]

With the configuration above, Absinthe will filter any variable whose name includes the terms token, password, or secret. The match is case sensitive.

The default is ["token", "password"].

Pipeline display

Absinthe can optionally display the list of pipeline phases for each processed document when logging. To enable this feature, set the :pipeline configuration option for this module:

config :absinthe, Absinthe.Logger,
  pipeline: true

The default is false.

Disabling

To display Absinthe logging, set the :log configuration option to false:

config :absinthe,
  log: false

The default is true.
