When a watch is triggered, its _input_ loads data into the execution
|
|
|
|
|
context. This payload is accessible during the subsequent watch execution
|
|
|
|
|
phases. For example, you can base a watch's condition on the data loaded by its
|
|
|
|
|
input.
|
|
|
|
|
|
|
|
|
|
{watcher} supports four input types:
|
|
|
|
|
|
|
|
|
|
* <<input-simple, `simple`>>: load static data into the execution context.
|
|
|
|
|
* <<input-search, `search`>>: load the results of a search into the execution
|
|
|
|
|
context.
|
|
|
|
|
* <<input-http, `http`>>: load the results of an HTTP request into the execution
|
|
|
|
|
context.
|
|
|
|
|
* <<input-chain, `chain`>>: use a series of inputs to load data into the
|
|
|
|
|
execution context.
|
|
|
|
|
|
|
|
|
|
NOTE: If you don't define an input for a watch, an empty payload is loaded
|
|
|
|
|
into the execution context.
