Items.serial(items, method, callback)
Runs method
against each value in the items
array in series. callback
is executed when all of the tasks are complete. Calling back with an error will short-circuit the remaining tasks.
items
an array of items to pass to method
.method
a function with the signature function (item, next)
.
item
- is the currently processing item in the items
array.next
- callback function to indicate the end of processing for item
. Calling next
with a truthy parameter indicates an error and ends Items.serial
.callback
- a function with the signature function (err)
.
err
- indicates any errors during processing.Items.parallel(items, method, callback)
Runs method
against each value in the items
array in parallel. callback
is executed when all of the tasks are complete. Calling back with an error will short-circuit the remaining tasks.

.callback
- a function with the signature function (err)

err
- indicates any errors during processing.Items.parallel.execute(tasks, callback)
Runs all of the functions in tasks
in parallel and stores the results in a collector object passed into callback
. If any of the tasks callback with an error, the collector object is null
.
tasks
- on object containing functions to execute in parallel. The key
of the function is the key
in the result of collector object. The task should have the signature function (next)
next(err, result)
- callback function to indicate the end of processing for the current task.
err
- indicates any errors during processing.result
- result of this function. This value will be set on the collector object in the final callback.callback(err, result)
err
- any errors reported by any of the tasks
.result
- an object containing the result of running all of the tasks
. result
will be null
if any of the tasks callback with an error. The result.key
will be the corresponding key
of the tasks
object.FAQs
