Generate Momentum CMS Collection

Create a new collection file following project conventions.

Arguments

• $ARGUMENTS - Collection name (e.g., "posts", "products", "users")

Important: Collection Location

All collections are defined in libs/example-config/src/collections/. Both example apps (example-angular, example-analog) import from @momentumcms/example-config/collections. Never define collections in individual apps.

Steps

1. Create the collection file at libs/example-config/src/collections/<name>.collection.ts

2. Use this template:

import {
  defineCollection,
  text,
  richText,
  number,
  date,
  checkbox,
  select,
  relationship,
} from '@momentumcms/core';

export const <PascalName> = defineCollection({
  slug: '<kebab-name>',

  admin: {
    useAsTitle: 'title', // or 'name' - the field to display as title
    defaultColumns: ['title', 'createdAt'],
    group: 'Content', // Admin sidebar group
  },

  access: {
    read: () => true,
    create: ({ req }) => !!req.user,
    update: ({ req }) => req.user?.role === 'admin',
    delete: ({ req }) => req.user?.role === 'admin',
  },

  hooks: {
    beforeChange: [],
    afterChange: [],
  },

  fields: [
    text('title', { required: true }),
    // Add more fields as needed
  ],
});

3. Export from libs/example-config/src/collections/index.ts:

// Add import at top
import { <PascalName> } from './<name>.collection';

// Add to the collections array
export const collections: CollectionConfig[] = [
  // ... existing collections,
  <PascalName>,
];

// Add to named exports
export {
  // ... existing exports,
  <PascalName>,
};

Both example apps automatically pick up changes since they import from @momentumcms/example-config/collections.

4. Remind user: if migration mode is enabled, run nx run <app>:migrate:generate after collection changes to create a migration file.
