Node.js

Required for all users

Markuplint v5 requires Node.js v22.0.0 or later. Check your version before upgrading.

Minimum Version: v22.0.0​

The minimum Node.js version has been raised from v18.18.0 to v22.0.0. All packages now enforce this through the engines field.

Check your current version:

node -v
# Must be v22.0.0 or later

Using a version manager​

# nvm
nvm install 22
nvm use 22

# volta
volta install node@22

Updating CI configuration​

# Before (v4)
node-version: [18, 20]

# After (v5)
node-version: [22, 24]

Removed Polyfills​

v5 uses native APIs instead of polyfills. These packages were removed internally:

  • uuid -- replaced by native crypto.randomUUID()
  • @ungap/structured-clone -- replaced by native structuredClone()
note

These are internal changes. If your project depended on these as transitive dependencies from Markuplint, add them directly to your package.json.

TypeScript Target Changed to ES2022​

The compilation target changed from ES2020 to ES2022. This affects custom rule and parser plugin authors who compile with Markuplint's TypeScript configuration.

Ensure your runtime supports ES2022 features like top-level await and Error.cause.
