OSMnexus by Laurenz

Laurenz has built a new Rust-based tool called OSMnexus for processing OpenStreetMap data. It takes a PBF file as input, for example a Germany extract, and processes it according to a JSON configuration. In its current form, the Germany dataset can be processed in about 10 minutes.

The configuration reflects the logic of Tilda Geo, especially for cycling infrastructure. This makes interactive workflows possible: the tool could run on a server, a user could define a bounding box in the browser, edit the configuration live, rerun the processing, and receive updated results for that area within a few minutes.

An advantage of the tool is that it supports both OSM feature extraction and graph creation. Because it splits ways at intersections, it can generate graph-ready data for routing or network analysis. The implementation was developed against Tilda’s cycling infrastructure data as a reference and iterate

Quick helper script to add `use client` to all ts/tsx files in all folders except when it was added already. (Thanks to Github Copilot for creating this.)
// 0. Stash everything in git to have a clean slate
// 1. Update `folderPath`
// 2. Run with `node add-use-client-to-all-files.cjs` from the root of your project

const path = require('path')
const folderPath = './src/app' // Replace with the path to your folder
