CF-Incidents Workflows, Workers - Declare Workflows in the `exports` configuration

[ENF News Bot]

You can now declare the Workflows a Worker defines in the exports field of your Wrangler configuration file. Previously, a Worker could only define a Workflow through a workflows binding, even when the Worker never called the Workflow itself.

Key each entry by the name of the class that extends WorkflowEntrypoint:

{
	"exports": {
		"MyWorkflow": {
			"type": "workflow",
			"name": "my-workflow",
			"limits": {
				"steps": 25000,
			},
			"schedules": ["0 * * * *"],
		},
	},
}

[exports.MyWorkflow]
type = "workflow"
name = "my-workflow"
schedules = [ "0 * * * *" ]

  [exports.MyWorkflow.limits]
  steps = 25_000

A workflow export accepts the same settings as a workflows binding: limits, schedules, and default_retention. When you run wrangler deploy, Wrangler creates or updates the Workflow with these settings.

You can declare a Workflow as both a binding and an export. Both declarations must use the same class, and cannot set the same setting to different values.

A workflows binding to a Workflow in another Worker cannot use the same name as a Workflow export in this Worker. Workflow names are unique per account.

Workflow exports require Wrangler 4.139.0 or above.
