Action Patterns

role:basic, note:true, cmd:set

Set a note value. Notes are a simple internal per-process communication mechanism for plugins to exchange data. In particular, plugins can set keyed values before the plugin that uses the data reads it. See seneca-admin for an example.

Parameters

• key: string; key name
• value: key value

Response:

• None.

role:basic, note:true, cmd:get

Get a note value.

Parameters

• key: string; key name

Response:

• value: key value, if defined

role:basic, note:true, cmd:push

Push a note value onto a list. The namespace for lists is separate from the namespace for single values. The list is created if it does not exist.

Parameters

• key: string; key name
• value: value to append to list.

Response:

• None.

role:basic, note:true, cmd:list

Get the full list of values for the key, in pushed order.

Parameters

• key: string; key name

Response:

• Array of values.

role:basic, note:true, cmd:pop

Get the last value of a list, and remove it from the list.

Parameters

• key: string; key name

Response:

• value: key value, if list was non-empty

Releases

• 0.3.0: 2015-06-15: Normalized note patterns. Prep for Seneca 0.6.2.
