Developing code navigation

This guide documents our approach to developing code navigation-related features in our codebase. This includes the code navigation logic included in the Sourcegraph instance as well as the extensions that provide code navigation to the web UI, browser extension, and code host integrations.

Services:

• precise-code-intel-worker

Code navigation-specific code:

• lib/codeintel
• dev/codeintel-qa
• enterprise/internal/codeintel
• cmd/worker/internal/codeintel
• cmd/frontend/internal/codeintel
• cmd/frontend/internal/executorqueue/queues/codeintel
