Add Momentum CMS Plugin (Monorepo)

Add Momentum CMS Plugin (Monorepo)

Add and configure a plugin in the Momentum CMS monorepo.

Arguments

• $ARGUMENTS - Plugin name: "analytics", "otel", "event-bus", or a custom plugin path

Important: Monorepo Context

In the monorepo, plugins are local packages under libs/​plugins/. Collections are defined in libs/​example-config/​src/​collections/. Both example apps (example-angular, example-analog) import from @momentumcms/​example-config.

Steps

1. Identify the plugin to add
2. Import the plugin factory in the app's momentum.config.ts
3. Configure the plugin and add to the plugins array
4. Run nx run example-angular:generate (or the relevant app target) to regenerate types and admin config
5. Restart the dev server

Official Plugins (Local Packages)

Analytics (@momentumcms/​plugins/​analytics)

Located at libs/​plugins/​analytics/. Adds event tracking, dashboards, and block-level analytics.

// In apps/​example-angular/​src/​momentum.config.ts
import { analyticsPlugin } from '@momentumcms/​plugins/​analytics';
import { eventBusPlugin } from '@momentumcms/​plugins/​core';

const events = eventBusPlugin();
const analytics = analyticsPlugin({
	trackCollections: true,
});

const config = defineMomentumConfig({
	// ...existing config
	plugins: [authPlugin, events, analytics],
});

What it adds:

• Analytics dashboard, content performance, tracking rules admin pages
• TrackingRules collection
• Block-level analytics fields injected via modifyCollections
• CRUD event tracking hooks
• Browser imports: @momentumcms/​plugins/​analytics/​admin-routes, @momentumcms/​plugins/​analytics/​block-fields

OpenTelemetry (@momentumcms/​plugins/​otel)

Located at libs/​plugins/​otel/. Distributed tracing for all collection operations.

import { otelPlugin } from '@momentumcms/​plugins/​otel';

const tracing = otelPlugin({ serviceName: 'momentum-cms' });

const config = defineMomentumConfig({
	plugins: [authPlugin, tracing],
});

Event Bus (@momentumcms/​plugins/​core)

Located at libs/​plugins/​core/. Pub/​sub for collection lifecycle events.

import { eventBusPlugin } from '@momentumcms/​plugins/​core';

const events = eventBusPlugin();

const config = defineMomentumConfig({
	plugins: [authPlugin, events],
});

After Adding a Plugin

nx run example-angular:generate    # Regenerate types and admin config
nx serve cms-admin                 # Restart dev server

Sidebar Icons

All heroicons/​outline are provided globally at the admin route level (provideAdminIcons() in libs/​admin/​src/​lib/​icons/​provide-admin-icons.ts). Plugins just set icon: 'heroChartBarSquare' (or any hero* name) in their admin route descriptor — no manual registration needed.

The icon field type is hero${string} for autocomplete. Browse available names at Heroicons. Naming: hero + PascalCase (e.g., heroEnvelopeOpen for envelope-open).

Creating a New Plugin

Create a new library under libs/​plugins/:

nx generate @nx/​js:library --name=my-plugin --directory=libs/​plugins/​my-plugin --tags="scope:lib,env:server"

Then implement the MomentumPlugin interface:

// libs/​plugins/​my-plugin/​src/​lib/​my-plugin.ts
import type { MomentumPlugin } from '@momentumcms/​core';

export function myPlugin(config: MyConfig): MomentumPlugin {
	return {
		name: 'my-plugin',
		collections: [],
		adminRoutes: [],
		modifyCollections(collections) {},
		async onInit(context) {},
		async onReady(context) {},
		async onShutdown(context) {},
		browserImports: {
			// Optional: expose browser-safe imports for admin config generation
			adminRoutes: {
				path: '@momentumcms/​plugins/​my-plugin/​admin-routes',
				exportName: 'myPluginAdminRoutes',
			},
		},
	};
}
