swf_runtime

Execution engine for Serverless Workflow DSL v1.0.0 — parse, validate, and run workflows.

Features

• Task runners — set, wait, raise, emit, switch, for, fork, do, try, listen, call, run, custom
• Expression engine — JQ-based evaluation (jaq) with runtime variable support ($context, $secret, $workflow, $task, $runtime)
• HTTP client — GET/POST/PUT/DELETE/PATCH with headers, query, auth (Basic, Bearer, Digest, OAuth2, OIDC)
• Shell execution — command, args, environment, return formats
• Sub-workflow — run nested workflow definitions with context propagation
• JSON Schema — input/output validation
• Secret manager — pluggable secret resolution ($secret variable)
• Execution listener — event-driven workflow monitoring
• Custom tasks — extensible via CustomTaskHandler trait
