Article details

  • Keyword: LaunchDarkly React SDK migration
  • Word count: 1533
  • Slug: launchdarkly-react-sdk-openfeature-migration
  • Meta description (154 chars): FlagLint audits your LaunchDarkly React SDK migration: detect useFlags and useVariation hooks, generate before/after diffs, and enforce OpenFeature in CI.

Why this keyword

No existing FlagLint blog post covers the React SDK migration path. The troubleshooting guide mentions React SDK hooks as manual-review items but gives no remediation guidance. Engineers searching "LaunchDarkly React SDK migration" or "useFlags openfeature react" find nothing from flaglint.dev. This article closes that gap directly.

What the article covers

  1. Problem statement — why the React SDK (useFlags, useVariation, useLDClient) can't be auto-migrated and why hooks are manual-review items in FlagLint output.
  2. Real CLI output — verbatim output of npx flaglint@latest audit ./src/content/docs/ (no matching files on the docs site) with instructions to run against a real app source.
  3. Before/after diffs for all three hooks:
    • useFlags() → one useFlag call per flag key
    • useVariation(key, default)useFlag(key, default) with destructured value
    • useLDClient()useOpenFeatureClient()
  4. Provider bootstrapOpenFeatureProvider setup at the app root.
  5. LDProvider removal order — remove last, after all hook call sites converted.
  6. CI enforcementflaglint validate --no-direct-launchdarkly in GitHub Actions.

Proofread checklist

  • CLI commands verified against flaglint --help and the real audit run
  • Real CLI output pasted verbatim (No matching files found. Check your .flaglintrc include patterns.)
  • Keyword "LaunchDarkly React SDK migration" appears 5 times (2 frontmatter, 3 body) — within 3–5 target
  • Meta description is 154 characters — within 150–160 target
  • Word count: 1533 — within 1200–1600 target
  • Internal links added: /blog/launchdarkly-flag-debt, /blog/five-patterns-that-block-migration, /docs/integrations/openfeature-provider, /blog/enforce-launchdarkly-migration-github-actions, /docs/guides/troubleshooting
  • No duplicate topic with existing guides or blog posts
