openlayers-nim

Nim JS bindings for OpenLayers. It follows typescript bidings mostly. Mostly generated with Codex, but guided to provide mostly sane API choices. PRs for more bindings / typed APIs accepted.

The best "docs" are to follow the OpenLayers docs and the ported examples below.

Examples

The interactive example app and individual example modules are in examples/. It uses Karax to switch between the examples.

• Main router app: examples/app.nim
• Per-example modules:
• examples/simple.nim
• examples/semiTransparentLayer.nim
• examples/selectFeatures.nim
• examples/selectHoverFeatures.nim
• examples/drawFeatures.nim
• examples/earthquakesHeatmap.nim
• examples/drawModifyTraceSnap.nim
• examples/layerOpacity.nim
• examples/attributions.nim
• examples/center.nim
• examples/iconSymbolizer.nim
• examples/markerAnimation.nim
• examples/geoJSON.nim
• examples/layerGroups.nim

Build the app:

• nim js -d:nodejs examples/app.nim

Serve examples locally:

• nim r examples/server.nim
• Open http://127.0.0.1:8080/examples/examples.html

You can also build any individual example module directly, for example:

• nim js -d:nodejs examples/drawFeatures.nim

Options

This module assumes ESM style modules, which can be opted out of by passing -d:openlayers.noEsmModules.
