Console Logging
- Never use
console.log, console.debug, or console.info in production code
- Only use
console.error and console.warn for actionable errors
- For debug logging, wrap in
if (IsDev) { ... }
- Don't use
biome-ignore to suppress console warnings - remove the logs instead
Rules
See rules/ directory for detailed guidance.
