Instructions

When the developer requests a new component:

Step 1: Gather Requirements

Ask for:

Component name (e.g., MapHeatmap, MapPolygon)
Core functionality
Whether it needs compound components (like MarkerContent, MarkerPopup)
Category: "core" or "features" (most components are features)
Lucide icon for the sidebar and components page
Whether it exposes a control hook (e.g., useHeatmapControl)

If there are multiple valid implementation approaches (e.g., Mapbox layers vs DOM overlay, canvas vs CSS animations, GeoJSON source vs custom rendering), present the options with trade-offs and let the developer choose before writing code.

Step 2: Create the Component File and Export

Follow the map component rules in .claude/rules/react/component.md for the component structure, template, patterns, and barrel export.

Location: src/registry/map/{component-name}.tsx
Use kebab-case for file names (e.g., heat-map.tsx)
Export from src/registry/map/index.tsx

Step 3: Add Registry Entry

Update registry.json by adding an entry to the items array.

Follow this structure:

{
  "name": "heat-map",
  "type": "registry:ui",
  "title": "Map Heatmap",
  "description": "Short description of the component.",
  "dependencies": ["mapbox-gl"],
  "devDependencies": ["@types/mapbox-gl"],
  "registryDependencies": ["https://www.terrae.dev/map.json"],
  "files": [
    {
      "path": "src/registry/map/heat-map.tsx",
      "type": "registry:ui",
      "target": "components/ui/map/heat-map.tsx"
    }
  ]
}

Key rules:

name uses kebab-case with ``prefix (e.g.,heat-map)
registryDependencies always includes ["https://www.terrae.dev/map.json"] (the core Map component that all other components depend on)
Add extra dependencies only if the component needs packages beyond mapbox-gl
Components that don't need mapbox-gl directly can have empty dependencies (e.g., watermark)

Step 4: Create Example File(s)

Location: src/app/docs/_components/examples/{name}-example.tsx

Use kebab-case for the file name.

The basic example should demonstrate the simplest usage of the component.

import { Map, MapHeatmap } from "@/registry/map"

export const HeatmapExample = () => {
  const accessToken = process.env.NEXT_PUBLIC_MAPBOX_ACCESS_TOKEN || ""

  return (
    <div className="h-full w-full">
      <Map accessToken={accessToken} center={[-74.006, 40.7128]} zoom={10}>
        <MapHeatmap id="heatmap-basic" {/* ...minimal props */} />
      </Map>
    </div>
  )
}

Key rules:

Only add "use client" if the example uses hooks, event handlers, or browser APIs — purely compositional examples that just render map components don't need it
Import from @/registry/map
Wrap the map in a <div className="h-full w-full">
Pass process.env.NEXT_PUBLIC_MAPBOX_ACCESS_TOKEN || "" as the access token — the Map component validates it and shows an error if missing, so examples don't need their own check
Export the component with a descriptive name (PascalCase)
Create additional example files for each variation (e.g., heatmap-color-example.tsx, heatmap-custom-example.tsx)

Step 5: Create Documentation Page

Location: src/app/docs/{slug}/page.tsx

Use the lines-animated/page.tsx as the gold standard reference.

The slug should match the sidebar href (e.g., /docs/heatmap → src/app/docs/heatmap/page.tsx).

import { DocsLayout, DocsSection, DocsCode, DocsLink } from "../_components/docs"
import { ComponentPreview } from "../_components/component-preview"
import { CodeBlock } from "../_components/code-block"
import { HeatmapExample } from "../_components/examples/heatmap-example"
import { getExampleSource } from "@/lib/get-example-source"
import { Metadata } from "next"
import { Table, TableBody, TableCell, TableHead, TableHeader, TableRow } from "@/components/ui/table"

export const metadata: Metadata = {
  title: "Heatmap",
}

const HeatmapPage = () => {
  const basicSource = getExampleSource("heatmap-example.tsx")

  return (
    <DocsLayout
      title="Heatmap"
      description="Short description of what the component does."
      prev={{ title: "Previous Component", href: "/docs/previous" }}
      next={{ title: "Next Component", href: "/docs/next" }}
    >
      <DocsSection title="Installation">
        <p>First, make sure you have the base map component installed:</p>
        <CodeBlock code={`npx shadcn@latest add https://www.terrae.dev/map.json`} language="bash" />
        <p className="mt-4">Then install the heatmap component:</p>
        <CodeBlock
          code={`npx shadcn@latest add https://www.terrae.dev/heat-map.json`}
          language="bash"
        />
      </DocsSection>

      <ComponentPreview code={basicSource}>
        <HeatmapExample />
      </ComponentPreview>

      {/* Additional sections with examples, props tables, etc. */}
    </DocsLayout>
  )
}

export default HeatmapPage

Key rules:

Always export metadata with a title
Use DocsLayout with title, description, prev, and next navigation links
First section is always "Installation" with two CodeBlocks (base map + component)
The basic ComponentPreview goes directly after Installation (no section title or description, just the demo)
Use ComponentPreview to wrap each example with its source code
Use getExampleSource("filename.tsx") to load example source code
Use DocsCode for inline code references in descriptions
Use DocsSection with a title for each section
Add a props Table when the component has many configurable props
Set prev/next to match adjacent items in the sidebar navigation

Step 6: Add to Sidebar

Update src/app/docs/_components/docs-sidebar.tsx:

Import the Lucide icon at the top (if not already imported)
Add a NavItem entry in the correct section of the navigation array
Add badge: "new"

{ title: "Heatmap", href: "/docs/heatmap", icon: Flame, badge: "new" },

Sections:

"Explore" — Story, Changelog
"Get Started" — Introduction, Installation, Comparison, Components, Hooks, Reference
"Core" — Map, Controls, Compass, Marker, Popup
"Features" — Everything else

Step 7: Add to Components Page

Update src/app/docs/components/page.tsx:

Import the Lucide icon at the top (if not already imported)
Add a ComponentItem entry to the components array
Add isNew: true

{
  title: "Heatmap",
  href: "/docs/heatmap",
  description: "Short description matching the registry description",
  icon: Flame,
  category: "features",
  installCommand: "npx shadcn@latest add https://www.terrae.dev/heat-map.json",
  isNew: true,
},

Key rules:

category is "core" or "features" (must match the sidebar section)
installCommand URL follows the pattern https://www.terrae.dev/{registry-name}.json
Add mapboxOnly: true if the component only works with Mapbox GL (not MapLibre)
Place the entry near similar components in the array

Step 8: Update Changelog

Update src/app/docs/changelog/page.tsx:

Add a new entry to the components array of the most recent (topmost) ChangelogEntry in the changelogs array:

{
  title: "Heatmap",
  description: (
    <>
      New <code className="rounded bg-muted px-1 py-0.5 text-xs">MapHeatmap</code> component for
      visualizing data density on the map. Supports customizable color ramps, radius control,
      and intensity adjustment.
    </>
  ),
  href: "/docs/heatmap",
},

Key rules:

Add under components for new components, features for new features, fixes for bug fixes, properties for new props
The description uses JSX with inline <code> tags for component names
Always include href linking to the docs page

Step 9: Review with User

Before finalizing, show all changes:

The component source code
The barrel export addition
The registry entry
The example file(s)
The documentation page
The sidebar entry
The components page entry
The changelog entry
