Feature Flags

Arguments:

  • $ARGUMENTS: Optional flags

Options

| Option | Purpose | |--------|---------| | (none) | Show all flags across all channels | | --diff <ch1> <ch2> | Compare flags between channels | | --cleanup | Show flags grouped by cleanup status | | --csv | Output in CSV format |

Channels

  • www, www-modern - Meta internal
  • canary, next, experimental - OSS channels
  • rn, rn-fb, rn-next - React Native

Legend

✅ enabled, ❌ disabled, 🧪 __VARIANT__, 📊 profiling-only

Instructions

  1. Run yarn flags $ARGUMENTS
  2. Explain the output to the user

Common Mistakes

  • Forgetting __VARIANT__ flags - These are tested both ways in www; check both variants
  • Comparing wrong channels - Use --diff to see exact differences
