Conness GIS

Conness GIS is an open-source, code-driven framework for building widget-based GIS web apps on MapLibre — a clone-and-edit alternative to proprietary GIS app builders. You build your app by editing configuration, not shell code. (It's named after Mount Conness in the Sierra Nevada.)

Drop your data in app/layers.ts, describe your app in app/settings.ts, and the framework assembles a full mapping application: a layer list, legend, basemap switcher, search, measure, draw, bookmarks, popups, a mobile layout, and more — all themeable from a single palette.

Documentation in progress

This site is being written (Phase 28). Pages are landing section by section; the structure in the sidebar is the build target.

Where to start

  • Introduction — what the kit is and what it can do.
  • Quick Start — clone, install, run.
  • Concepts — the shell / user-surface boundary and how configuration flows.

How the docs are organized

  • Getting Started — install it, run it, and learn the core mental model.
  • Configuration — every setting you can edit in the app/ user surface (no shell code).
  • Widgets — a catalog of the built-in widgets, how to place them, and their config.
  • Guides — follow-along tutorials, including building your own widget.
  • Internals — architecture notes for contributors working on the shell itself.
