## What it does

This skill equips coding agents with patterns for serverless map tiles using PMTiles and MapLibre GL JS. A single `.pmtiles` archive packages an entire tile pyramid. MapLibre fetches only the needed bytes via HTTP range requests, eliminating the need for a dynamic database backend.

MapLibre does not read PMTiles natively. Integration requires the `pmtiles` package and a registered protocol via `maplibregl.addProtocol('pmtiles', protocol.tile)`. While MapLibre GL JS 4.0.0 changed `addProtocol` to a promise-based signature requiring a `{data}` return object, `pmtiles` version 3.0.0 and above handles this compatibility automatically.

Protomaps basemaps rely on OpenStreetMap, making OSM attribution mandatory in your style. For custom datasets, you can generate archives using Planetiler, tippecanoe, or the PMTiles CLI.

## Requirements
- Works with: GitHub

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add maplibre/maplibre-agent-skills --skill maplibre-pmtiles-patterns -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/maplibre-pmtiles-patterns/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/maplibre-pmtiles-patterns/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add maplibre/maplibre-agent-skills --skill maplibre-pmtiles-patterns -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/maplibre-pmtiles-patterns/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add maplibre/maplibre-agent-skills --skill maplibre-pmtiles-patterns -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/maplibre-pmtiles-patterns/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install maplibre/maplibre-agent-skills maplibre-pmtiles-patterns
```

2. **Manually: put the files in place**
- File: `.github/skills/maplibre-pmtiles-patterns/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add maplibre/maplibre-agent-skills --skill maplibre-pmtiles-patterns -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/maplibre/maplibre-agent-skills --path skills/maplibre-pmtiles-patterns
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/maplibre-pmtiles-patterns/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add maplibre/maplibre-agent-skills --skill maplibre-pmtiles-patterns -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/maplibre/maplibre-agent-skills/tree/HEAD/skills/maplibre-pmtiles-patterns/SKILL.md

## When to use it
- Connect a `.pmtiles` archive to MapLibre GL JS using the custom protocol
- Host vector and raster map tiles on static storage such as AWS S3 or Cloudflare R2
- Configure terrain layers with `raster-dem` without running a dynamic tile server
- Produce single-file map datasets from OpenStreetMap using Planetiler or tippecanoe

## Example prompts
- Show me how to register the pmtiles protocol and add a vector source in MapLibre GL JS
- Configure a MapLibre style using a remote PMTiles archive hosted on S3
- How do I handle the addProtocol change in MapLibre GL JS v4 when loading PMTiles?

# MapLibre PMTiles Patterns

PMTiles is a single-file format for vector or raster map tiles. You host one (or a few) files on any static host; MapLibre requests byte ranges over HTTP. No tile server, no dynamic backend. This skill covers when to use PMTiles, how to generate and host them, and how to connect them to MapLibre GL JS.

## When to Use This Skill

- Hosting map tiles without running a tile server (S3, Cloudflare R2, GitHub Pages, etc.)
- Building a fully static or serverless map stack
- Serving large tile sets from a CDN with range requests
- Generating PMTiles from OSM or other sources (Planetiler, tippecanoe)
- Using Overture Maps or other single-file tile datasets with MapLibre

## What PMTiles Is and Why It Matters

- **Vector and raster** — PMTiles supports both. A file can contain vector layers (e.g. water, roads, POIs), raster imagery (PNG/JPEG), or raster-dem (elevation, e.g. Terrarium format for terrain). In the style you use `type: 'vector'`, `type: 'raster'`, or `type: 'raster-dem'` accordingly.
- **Single file per map** — One `.pmtiles` file typically contains the full tile pyramid (all zoom levels) and all layers (vector or raster) in one archive. The format stores tiles in a compact layout (e.g. Hilbert curve) so the client can request only the byte ranges it needs. For very large coverage you may split by region into multiple files.
- **HTTP range requests** — The client requests only the byte ranges it needs (e.g. one tile), so the server does not need to understand x/y/z. Any host that supports `Range` headers works.
- **Serving** — You can serve directly from static storage (S3, R2, GitHub Pages, Netlify): the client uses range requests, so no tile server is required. Alternatively, [tileserver-gl](https://github.com/maptiler/tileserver-gl) or [Martin](https://maplibre.org/martin/) can serve PMTiles (from local paths, HTTP URLs, or S3), useful if you want one server that also provides styles, glyphs, or other sources.
