The Maps API for JavaScript is organized into a number of modules. Developers can therefore use the API efficiently by selecting only the modules which their applications require.

The table below outlines the selectable modules of the Maps API for JavaScript and their dependencies:

Module name	Module depends on	Description
`core (mapsjs-core.js)`	no dependencies	This module contains the core functionality for rendering maps, map layers and map objects as well as utilities used in other modules. This module is the core of the API. It has no dependencies but is essential for all other modules, which depend on it.
`core-legacy` `(mapsjs-core-legacy.js)`	core	This module contains the core module functionality that ensures support of the legacy browsers as well as it offers limited backwards compatability with the Maps API for JavaScript version 3.0.
`service` `(mapsjs-service.js)`	core	This module supports map tile retrieval, routing, geocoding, and so on.
`service-legacy` `(mapsjs-service-legacy.js)`	core, service	This module contains the service module functionality that ensures support of the legacy browsers as well as it offers limited backwards compatability with the Maps API for JavaScript version 3.0.
`mapevents` `(mapsjs-mapevents.js)`	core	This module provides functionality to enable user-interaction with the map, including map panning and pinch-to-zoom. The module normalizes various browser event systems (mouse events, touch events, pointer events) to offer unified events that can be used across desktop and mobile environments.
`ui` `(mapsjs-ui.js + mapsjs-ui.css)`	core	This module provides a set of pre-built cross-browser UI components (such as base map settings, zoom control, map scale) that can be added to the map. It also provides functionality to display location-specific info bubbles with arbitrary HTML content on the map.
