A Node.js library for creating map images with markers, polylines, polygons and text. This library is a JavaScript implementation of Static Map.
Image manipulation is based on Sharp. Pre-compiled libvips binaries for sharp are provided for use with Node.js versions 14+ on macOS (x64, ARM64), Linux (x64, ARM64) and Windows (x64, x86) platforms. For other OS or using with Heroku, Docker, AWS Lambda please refer to sharp installation instructions.

| 1.13.1+ | 0.33.2 | 8.15.1 | 18.17.0+ |
| 1.12.0 | 0.31.3 | 8.13.3 | 14.15.0+ |
| 1.11.1 | 0.31.3 | 8.13.3 | 14.15.0+ |
