PhoenixKit.Modules.Sitemap.Sources.Source behaviour (phoenix_kit v1.7.178)

Copy Markdown View Source

Behaviour for sitemap data sources.

Each source module must implement this behaviour to provide URL entries for sitemap generation.

Required Callbacks

  • source_name/0 - Unique atom identifier for the source
  • enabled?/0 - Whether this source is active
  • collect/1 - Collect URL entries from this source

Optional Callbacks

  • sitemap_filename/0 - Custom filename for the module's sitemap file
  • sub_sitemaps/1 - Split into multiple sub-sitemap files (e.g., per-blog, per-entity-type)
  • sitemap_settings_schema/0 - Declare source-specific settings for the admin UI

Summary

Types

settings_field()

Describes one source-specific setting for the admin settings UI.

Callbacks

collect(opts)

Collects all URL entries from this source.

enabled?()

Checks if this source is enabled and should be included in sitemap.

sitemap_filename()

Returns the base filename for this source's sitemap file (without .xml extension).

sitemap_settings_schema()

Declares source-specific settings for the sitemap admin settings page.

source_name()

Returns the unique name/identifier for this source.

sub_sitemaps(opts)

Returns a list of sub-sitemaps for sources that produce multiple files.

Functions

get_settings_schema(source_module)

Returns the settings schema for a source module.

get_sitemap_filename(source_module)

Returns the sitemap filename for a source module.

get_sub_sitemaps(source_module, opts \\ [])

Returns sub-sitemaps for a source module, or nil if not implemented.

safe_collect(source_module, opts \\ [])

Safely collects entries from a source, handling errors gracefully.

valid_source?(module)

Helper function to check if a source module is valid.

Types

settings_field()

@type settings_field() :: %{
  key: String.t(),
  type: :boolean | :string | :integer,
  label: String.t(),
  help: String.t() | nil,
  default: term()
}

Describes one source-specific setting for the admin settings UI.

  • key - the PhoenixKit.Settings key this field reads/writes
  • type - controls both the input widget and how the stored string is parsed (:boolean -> toggle, :string -> text input, :integer -> number input)
  • label - field label shown to the admin
  • help - optional helper text shown below the label
  • default - value used when the setting has never been saved

Callbacks

collect(opts)

@callback collect(opts :: keyword()) :: [PhoenixKit.Modules.Sitemap.UrlEntry.t()]

Collects all URL entries from this source.

enabled?()

@callback enabled?() :: boolean()

Checks if this source is enabled and should be included in sitemap.

sitemap_filename()

(optional) 
@callback sitemap_filename() :: String.t()

Returns the base filename for this source's sitemap file (without .xml extension).

Default: "sitemap-#{source_name()}"

sitemap_settings_schema()

(optional) 
@callback sitemap_settings_schema() :: [settings_field()]

Declares source-specific settings for the sitemap admin settings page.

Optional. A source that implements this returns a list of field descriptors; the settings page renders one input per field (grouped under the source's name), reads/writes each through PhoenixKit.Settings using its key and default, and invalidates the sitemap cache on save — the same way the page's built-in settings work.

Only add this for settings that don't already have a UI. Don't reimplement fields the core sitemap settings page already exposes (e.g. the built-in sitemap_include_* toggles).

Example

def sitemap_settings_schema do
  [
    %{
      key: "sitemap_entities_include_index",
      type: :boolean,
      label: "Include entity index pages",
      help: "Adds the /entities listing page alongside individual entries",
      default: true
    }
  ]
end

source_name()

@callback source_name() :: atom()

Returns the unique name/identifier for this source.

sub_sitemaps(opts)

(optional) 
@callback sub_sitemaps(opts :: keyword()) ::
  [{String.t(), [PhoenixKit.Modules.Sitemap.UrlEntry.t()]}] | nil

Returns a list of sub-sitemaps for sources that produce multiple files.

Return nil for a single file, or a list of {group_name, entries} tuples for per-group splitting (e.g., per-blog, per-entity-type).

Each group will be saved as sitemap-{source}-{group_name}.xml.

Functions

get_settings_schema(source_module)

@spec get_settings_schema(module()) :: [settings_field()]

Returns the settings schema for a source module.

Calls the optional sitemap_settings_schema/0 callback if implemented, otherwise returns [] (no source-specific settings to render).

get_sitemap_filename(source_module)

@spec get_sitemap_filename(module()) :: String.t()

Returns the sitemap filename for a source module.

Calls the optional sitemap_filename/0 callback if implemented, otherwise returns "sitemap-#{source_name()}".

get_sub_sitemaps(source_module, opts \\ [])

@spec get_sub_sitemaps(
  module(),
  keyword()
) :: [{String.t(), [PhoenixKit.Modules.Sitemap.UrlEntry.t()]}] | nil

Returns sub-sitemaps for a source module, or nil if not implemented.

safe_collect(source_module, opts \\ [])

@spec safe_collect(
  module(),
  keyword()
) :: [PhoenixKit.Modules.Sitemap.UrlEntry.t()]

Safely collects entries from a source, handling errors gracefully.

valid_source?(module)

@spec valid_source?(module()) :: boolean()

Helper function to check if a source module is valid.
