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, i).
    • 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.
    • i - The current item's index in the items array.
  • 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.

  • items an array of items to pass to method.
  • method a function with the signature function (item, next, i).
    • 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.parallel.
    • i - The current item's index in the items array.
  • 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.
