Street Space Editor for OpenStreetMap

• Open the editor
• Learn more about the project in the launch post.

One app with a shared OSM shell (auth, fetch, changeset upload) and modes for visualization and editing:

Mode	Status
Parking	Active
Width	Active
Bicycle	Active
Lanes	Planned
Surface	Active
Sidewalks	Planned

Modes plug into app/src/modes/; the shell lives in app/src/shell/. Shared kit packages remain under packages/*.

Deploy path: Vite / GH Pages base is /street-space-editor/.

Using correct Node version

The correct Node version is specified in .nvmrc.

For an easy way to automatically use this Node version just for your current shell:

• Install nvm
  • Using the install script
  • Or using Homebrew
• Run nvm use to automatically use the Node version specified in the .nvmrc. You may need to nvm install.

Development

From the repo root:

bun install
bun run dev

The Vite app lives in app/ (@osm-editor-kit/street-space-editor). Run bun run check from the root before pushing.

Dev OSM data: In development, the app defaults to a local Berlin fixture served as OSM Map API bbox slices (dev-osm-map-fixture). Use the debug panel’s “Live OSM viewport fetch” toggle to hit the real OSM Map API instead. The fixture file is downloaded on bun run dev via predev if missing.

Audit — how the app understands OSM data

Flat audit pages (no mode chrome) for reviewing interpretation rules and fixtures:

Local (with bun run dev):

• Width audit — measure rules and tag relations
• Lanes audit — cross-section / plan-sketch interpretation (one demo per URL)

Deployed:

• https://osmberlin.github.io/street-space-editor/audit-width
• https://osmberlin.github.io/street-space-editor/audit-lanes/one-lane-each-way

Install git hook

Husky runs bun run check-pre-push on pre-push (type-check, lint, format, test-run — same areas as CI). See .husky/pre-push.
