Create / modify a state machine definition

Command: $ sfn build --definition-file my-definition.yaml

If the my-definition.yaml file doesn't exist, you will be prompted to create it. The tool will then create a skeleton of an ASL definition and guide you through creating the initial state.

Browse and inspect state machines

Command: $ sfn inspect

Options:
  -n, --name-prefix [prefix]          Name prefix of state machine (optional) (default: "")
  -s, --status-filter [statusFilter]  Execution status filter. One of RUNNING | SUCCEEDED | FAILED | TIMED_OUT | ABORTED (optional)
  -p, --profile [profile]             AWS profile to use (default: "default")

Real time sync your local ASL with the cloud

Prerequisites is that the state machine is already deployed and that the local ASL definition matches the one that's deployed. This command supports SAM's DefinitionSubstitutions and a key/value map between substitution keys and actual values will be compiled at start-up.

Command: $ sfn sync

Usage: sfn sync|s [options]

Known issues

• Boolean logic in Choice states is not yet implemented
• By design, the tool will not guide you through adding ARNs and other parameters to SDK integrations. This is best done in a code editor.
