OpenLayers architecture & patterns

OpenLayers separates concerns with View, Layer, and Source: the view handles projection and resolution, layers define how data is rendered, and sources fetch tiles or features.

Layering patterns

Split basemap, business vectors, labels, and sketch layers so you can update and style them independently.

When integrating with frameworks, wrap the map in a module that exposes domain methods (highlight, fly-to) instead of touching low-level APIs from every component.
