Robocorp Work Items library

robocorp-workitems

Work items are used in Robocorp Control Room for managing data that go through multiple steps and tasks inside a process. Each step of a process receives input work items from the previous step, and creates output work items for the next step.

Getting started

The library exposes two objects, inputs and outputs, which are the main way to interact with work item queues. The former deals with the reading input work items, and the latter with creating output work items.

A run inside Control Room will always have at least one work item available to it. The simplest Robot which reads the current work item and creates an output can be done in the following manner:

from robocorp import workitems
from robocorp.tasks import task

@task
def handle_item():
    item = workitems.inputs.current
    print("Received payload:", item.payload)
    workitems.outputs.create(payload={"key": "value"})

Iterating over all available input items in the queue is also easy:

from robocorp import workitems
from robocorp.tasks import task

@task
def handle_all_items():
    for item in workitems.inputs:
        print("Received payload:", item.payload)
        workitems.outputs.create(payload={"key": "value"})

Work item structure

A work item's data payload is JSON and allows storing anything that is JSON serializable. By default the payload is a mapping of key-value pairs.

In addition to the payload section, a work item can also contain files, which are stored within Robocorp Control Room. Adding and using files with work items requires no additional setup from the user.
