workflow-plugin-admin

External Workflow plugin that provides an embedded admin mini-app, a typed admin.dashboard module, and strict protobuf contracts for contributed admin surfaces.

What It Does

• Hosts a runtime admin contribution registry through admin.dashboard.
• Lets workflows/plugins register admin surfaces with step.admin_register_contribution.
• Lists contributed surfaces with step.admin_list_contributions.
• Enforces default-deny admin action behavior with step.admin_authorize_action and upstream authz evidence.
• Provides a static admin shell that can render built-in identity, authorization, and contribution panels.
• Advertises module, step, and service-method contracts through plugin.contracts.json and ContractRegistry().

Authentication and authorization are intentionally composed with other Workflow plugins. Use auth.jwt or another auth plugin for identity, then run workflow-plugin-authz steps before admin action/list steps. Admin consumes the authorization evidence and denies missing evidence by default.

Contracts

Module:

• admin.dashboard

Steps:

• step.admin_register_contribution
• step.admin_list_contributions
• step.admin_authorize_action
• step.admin_resource_action

Service methods on admin.dashboard:

• RegisterContribution
• ListContributions
• AuthorizeAction
• DispatchResourceAction

The protobuf package is workflow.plugins.admin.v1.

Minimal Composition

modules:
  - name: auth
    type: auth.jwt
    config:
      issuer: my-app

  - name: authz
    type: authz.casbin

  - name: admin
    type: admin.dashboard
    config:
      route_prefix: /admin
      app_name: My App
      target_app: my-app
      auth_module: auth
      authz_module: authz

pipelines:
  register-admin-surface:
    trigger:
      type: manual
    steps:
      - name: register
        type: step.admin_register_contribution
        config:
          module: admin
        input:
          id: orders
          title: Orders
          path: /admin/orders
          render_mode: json-schema

See examples/minimal/config.yaml and workflow-scenarios scenario 89-admin-dashboard for the app + admin composition pattern.

Build

make build

Test

GOWORK=off go test ./...

Install

make install DESTDIR=/path/to/workflow

The install target copies the plugin binary, plugin.json, plugin.contracts.json, and embedded UI assets to DESTDIR/data/plugins/workflow-plugin-admin/.

UI Assets

internal/ui_dist/index.html contains the embedded admin shell. It fetches contributions from /api/admin/contributions by default; compose that endpoint with Workflow routes/pipelines backed by admin steps and auth/authz checks.
