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 3. For --diff, highlight meaningful differences
Common Mistakes
- **Forgetting `__VARIANT__` flags** - These are tested both ways in www; check both variants
- **Comparing wrong channels** - Use `--diff` to see exact differences
