create-content-component

name	create-content-component
description	Creates a new page builder content component for both Strapi and the Next.js frontend. Triggers: add/create page component, new page section, page builder component, add form component.

Add Page Builder

Add a new page builder (component) to both Strapi and the Next.js frontend.

Input Validation

Before proceeding, validate inputs:

• Name: must be kebab-case, lowercase only (e.g. pricing-table). Reject PascalCase/camelCase like MyComponent or pricingTable — ask user to correct.
• Category: must be lowercase, no spaces (e.g. sections, forms). Reject invalid formats.

If invalid format provided, ask user to correct before proceeding.

Inputs

Ask the user for:

• Name: kebab-case component name (e.g. testimonials, pricing-table)
• Category: one of sections, forms, utilities, seo-utilities, elements (default: sections), or any custom category.
• Attributes: what fields the component needs (e.g. title, description, image, items list)

Custom Category Handling

If category doesn't exist in apps/strapi/src/components/, create the folder first before creating the component schema.

Duplication prevention

Before proceeding, first check if the component or similar one already exists in Strapi or the Next.js frontend. If so, ask user if they want to proceed, or go with a different name.

Naming Convention

Given category sections and name testimonials:

• Strapi UID: sections.testimonials
• Strapi file: apps/strapi/src/components/sections/testimonials.json
• collectionName: components_sections_testimonials (format: components_{category}_{name_underscored})
• React component: StrapiTestimonials (prefix Strapi + PascalCase of name)
• React file: apps/ui/src/components/page-builder/components/sections/StrapiTestimonials.tsx

Steps

1. Create Strapi component schema

Create apps/strapi/src/components/{category}/{name}.json:

{
  "collectionName": "components_{category}_{name_with_underscores}",
  "info": {
    "displayName": "{PascalCaseName}",
    "description": ""
  },
  "options": {},
  "attributes": {
    "title": {
      "type": "string",
      "required": true
    }
  }
}

Populate attributes based on user requirements. Common attribute patterns:

• Text: { "type": "string" } or { "type": "text" } (multiline) or { "type": "richtext" }
• Required: add "required": true
• Nested component: { "type": "component", "repeatable": false, "component": "utilities.link" }
• Repeatable component: { "type": "component", "repeatable": true, "component": "utilities.basic-image" }
• Media: use a component like utilities.image-with-link or utilities.basic-image
• Enum: { "type": "enumeration", "enum": ["option1", "option2"] }
• Boolean: { "type": "boolean", "default": false }

Additional attribute options (add as needed):

• description: admin UI hint (e.g. "description": "Displayed below the section title")
• default: default value (e.g. "default": "Click here")
• minLength/maxLength: string length constraints (e.g. "minLength": 3, "maxLength": 100)
• min/max: number constraints
• private: hide from API response (e.g. "private": true)

Reference the strapi documentation for more information on component schemas: https://docs.strapi.io/cms/backend-customization/models#model-schema

2. Register in page dynamic zone

Edit apps/strapi/src/api/page/content-types/page/schema.json.

Add the new UID to the attributes.content.components array:

"content": {
  "type": "dynamiczone",
  "components": [
    ...existing,
    "{category}.{name}"
  ]
}

3. Add population rules

Add files to apps/strapi/src/populateDynamicZone folder.

import type { Modules } from "@strapi/strapi"

import basicImagePopulate from "../utilities/basic-image"
import linkPopulate from "../utilities/link"

export default {
  populate: {
    links: linkPopulate,
    image: basicImagePopulate,
    steps: true,
  },
} satisfies Modules.Documents.Params.Populate.NestedParams<"{category}.{name}">

• Use true if the component has no nested relations/components (like "utilities.ck-editor-content": true)
• Use { populate: { fieldName: true } } for simple nested components
• Use { populate: { fieldName: { populate: { media: true } } } } for deeply nested media
• Match the pattern of existing entries — only populate relations and components, not scalar fields
• When component has different component inside in Strapi, always import its population config and reuse it.
• Type object-based populate exports with Modules.Documents.Params.Populate.NestedParams<"{category}.{name}"> so TypeScript validates field names against the generated Strapi component schema.

4. Create React component

Create apps/ui/src/components/page-builder/components/{category}/Strapi{PascalCaseName}.tsx:

import { Data } from "@repo/strapi-types"

import { removeThisWhenYouNeedMe } from "@/lib/general-helpers"
import { Container } from "@/components/elementary/Container"

export function Strapi{PascalCaseName}({
  component,
}: {
  readonly component: Data.Component<"{category}.{name}">
}) {
  removeThisWhenYouNeedMe("Strapi{PascalCaseName}")

  return (
    <section>
      <Container className="py-8">
        <h2 className="mb-4 text-3xl font-bold">{component.title}</h2>
        {/* TODO: Implement component UI */}
      </Container>
    </section>
  )
}

Strapi{PascalCaseName}.displayName = "Strapi{PascalCaseName}"

export default Strapi{PascalCaseName}

Key patterns:

• Named export + default export
• Props typed with Data.Component<"{category}.{name}"> from @repo/strapi-types
• removeThisWhenYouNeedMe call — starter template placeholder, keep it for new components
• displayName set explicitly
• Wrap content in <Container> from @/components/elementary/Container, if it's not a root level component, or not explicit "container" component wrapping other components.
• Follow the repository Code Style Guide

5. Register in PageContentComponents

Edit apps/ui/src/components/page-builder/index.tsx:

1. Add import at top (alphabetical within category group):

import Strapi{PascalCaseName} from "@/components/page-builder/components/{category}/Strapi{PascalCaseName}"

2. Add mapping entry in PageContentComponents under the matching category comment:

"{category}.{name}": Strapi{PascalCaseName},

6. Generate types

Run:

cd apps/strapi && pnpm generate:types

This updates @repo/strapi-types so the React component gets proper typing for Data.Component<"{category}.{name}">.

Path Resilience

If expected paths are not found, search for existing similar files before reporting an error. Example: glob for **/page-builder/**/Strapi*.tsx to find component location.
