### Optional: Use FlagLint

For larger JavaScript and TypeScript codebases, you can use [FlagLint](https://flaglint.dev/) to analyze supported direct LaunchDarkly Node.js SDK usages with AST analysis:

```bash
# List detected call sites
npx flaglint scan ./src

# Summarize migration risk and readiness
npx flaglint audit ./src

# Preview safe OpenFeature call-site rewrites without changing files
npx flaglint migrate ./src --dry-run
```

The migration preview skips usages that FlagLint cannot safely rewrite. FlagLint analyzes application call sites but does not migrate flag definitions, targeting rules, environment configuration, backend state, or provider setup.
