Minimap Plugin for Maplibre-gl Map Engine

This package provides a configurable MiniMap component to use with the MapLibre GL project. It allows you to display a small overview map alongside the main map, with customizable options for size, zoom level, interactions, and styling, making it a flexible tool for enhancing your MapLibre GL applications.

!!!Note: This library is currently in development and not yet ready for production use. Use it at your own risk, and expect potential changes in future releases.!!!

Instructions

• Install the plugin using your package manager

$ npm i maplibregl-minimap

• import it into your project and use it directly

import MinimapControl from "maplibregl-minimap";

const miniMapConfig = {
  id: "myCustomMiniMap",
  width: "200px",
  height: "200px",
  zoomLevelOffset: 6,
  interactions: { drag: true, zoom: false },
  initialMinimized: false,
  minimizableMinimap: true,
  collapsedWidth: "30px",
  collapsedHeight: "30px",
  borderRadius: "5px",
};

// after the initilize your map
map.on("load", () => {
  map.control(new MinimapControl(miniMapConfig));
});

MiniMap Configuration

The configuration object for the MiniMap allows you to control its size, visibility, interaction, and style. Below are the available options. It's possible to

Configuration Properties

export type MiniMapConfiguration = Partial<{
  showText: string;
  hideText: string;
}> & {
  id: string;
  width: string;
  height: string;
  zoomLevelOffset: 5 | 6 | 7 | 8;
  interactions: MinimapInteractions;
  initialMinimized: boolean;
  minimizableMinimap: boolean;
  collapsedWidth: string;
  collapsedHeight: string;
  borderRadius: string;
  style: StyleSpecification;
};

Property Descriptions

• id (string, required): Set a custom id for the minimap. This must be unique within your application.
• width (string, optional, default: 150px): Defines the width of the minimap container.
• height (string, optional, default: 150px): Defines the height of the minimap container.
• zoomLevelOffset (5 | 6 | 7 | 8, optional, default: 5): Sets the zoom offset for the minimap relative to the parent map.
• interactions (MinimapInteractions, optional, default: all disabled): Specifies which interactions (like zoom, drag, etc.) are enabled or disabled on the minimap.
• initialMinimized (boolean, optional, default: true): Determines whether the minimap is minimized when it first loads.
• minimizableMinimap (boolean, optional, default: true): Whether the minimap can be minimized or not. If set to false, the minimize button will be disabled.
• collapsedWidth (string, optional, default: 29px): The width of the minimap when it is minimized.
• collapsedHeight (string, optional, default: 29px): The height of the minimap when it is minimized.
• borderRadius (string, optional, default: 3px): Sets the border radius for the minimap container.
• style (StyleSpecification, optional): Custom style object for further styling the minimap. This allows you to define specific visual properties like colors, borders, etc.

To-Do/Fix

• Bundling the package results in losing types and autocompletion provided by the intellisence. (partially solved but still the importer script doesn't recognize types and intellisense doesn't autocomplete while typing... (WIP)
• figure out what is the initial yet optimal value for 'zoomLevelOffset'.
• optimize the package size (currently ~600KB).
