workflow-core

@foresthubai/workflow-core

Headless workflow model, serialization, and pure validation for the ForestHub edge-agents platform. No React, no DOM, no browser dependencies — this package is the language-neutral TypeScript binding for the workflow graph format defined in contract/workflow.yaml.

The Go engine and the React-based workflow builder both consume this contract. This package gives TypeScript callers the same three-layer model — generated API types (the wire format), a hand-written domain model, and a pure validateWorkflowState validator — without pulling in any UI or runtime machinery.

Install

npm install @foresthubai/workflow-core

Quickstart

import { deserialize, validateWorkflowState } from "@foresthubai/workflow-core";

// `apiWorkflow` is the wire-format JSON produced by the engine or the builder.
const workflow = deserialize(apiWorkflow);
const result = validateWorkflowState(workflow);

if (!result.ok) {
  for (const diagnostic of result.diagnostics) {
    console.error(diagnostic.message);
  }
}

Subpath exports (/api, /node, /edge, /channel, /memory, /model, /deploy, /parameter, /function, /variable, /expression, /workflow, /diagnostics, /migration, /id) expose the individual domain modules; the root barrel re-exports the most common types and the validator.

Architecture

The repository ts/CLAUDE.md and workflow-core/docs/ have the canonical write-ups on the API/domain/store layering, the parameter contract, and the Api-prefix naming convention. The short version:

• API layer (src/api/) — generated from contract/workflow.yaml. Never hand-edit; regenerate with npm run generate.
• Domain layer (src/{node,edge,channel,memory,model,function,workflow, parameter,variable,expression}/) — hand-written in-memory shape for validation and import/export.
• Validation — validateWorkflowState runs on the domain Workflow.
