Plugin Development

MIFY supports a plugin system that lets you extend the platform with custom nodes, adapters, and credentials.

Plugin Types

Extension Point	What You Can Add
Nodes	Custom processing nodes for workflows
Adapters	Integrations with external platforms
Credentials	Custom credential types for your integrations

Creating a Plugin

1. Initialize

Use the MIFY Plugin CLI:

npx mify-plugin init my-plugin
cd my-plugin

This creates a plugin project with:

• manifest.json — plugin metadata and configuration
• src/ — plugin source code
• tests/ — test files

2. Define Your Manifest

The plugin manifest (v1.4.0) describes your plugin:

{
  "name": "my-plugin",
  "version": "1.0.0",
  "description": "What my plugin does",
  "author": "Your Name",
  "mifyVersion": ">=1.0.0",
  "extensionPoints": {
    "nodes": ["src/nodes/MyNode.ts"],
    "adapters": ["src/adapters/MyAdapter.ts"]
  },
  "permissions": ["network", "storage"],
  "runtime": "v8"
}

3. Implement Your Extension

For a custom node:

export class MyNode implements NodeImplementation {
  async execute(input: Record<string, unknown>, context: ExecutionContext) {
    // Your logic here
    return { result: "processed" };
  }
}

4. Test Locally

npx mify-plugin dev    # Start dev server with hot reload
npx mify-plugin test   # Run tests
npx mify-plugin validate  # Check manifest and code

5. Publish

npx mify-plugin publish

Published plugins appear in the Plugin Marketplace at /plugins/marketplace.

Plugin Marketplace

Browse and install plugins at /plugins/marketplace:

• Search by category and capability
• View ratings and reviews
• One-click install for verified plugins
• Version pinning and channel selection (stable/beta/canary)

Runtime Environments

Plugins run in sandboxed environments:

Runtime	Use Case
V8	JavaScript/TypeScript plugins (default)
WASM	WebAssembly plugins for performance-critical code

Plugin Lifecycle

Hook	When Called
onInstall	Plugin first installed
onUpgrade	Plugin version updated
onRemove	Plugin uninstalled

Managing Plugins

• Install: /plugins/marketplace/[id] → Install
• Configure: /plugins/[id]/settings → Plugin-specific settings
• Register custom: /plugins/register → Upload your own plugin
• Admin: /admin/plugins → Manage all installed plugins
