A Professional Git Worktree Workflow with a Bare Repository

5 minute read

Published:

If you regularly switch between branches, keep separate runtime environments, or want AI agents to work without disturbing your main checkout, a bare repository plus git worktree is one of the cleanest setups.

GraphHopper paths are edges, not nodes

Published:

GraphHopper makes a deliberate design choice: paths are represented by edges, not nodes. This matters for correctness (turn restrictions/costs), fidelity (multiple parallel edges between the same nodes), and efficiency (edge properties drive routing).
