Breaking

• Changed behavior when max is set to 0:
  • Previously, max: 0 was treated as a 'disable' flag and would allow all requests through.
  • Starting with v7, all requests will be blocked when max is set to 0.
  • To replicate the old behavior, use the skip function instead.
• Renamed req.rateLimit.current to req.rateLimit.used.
  • current is now a hidden getter that will return the used value, but it will not appear when iterating over the keys or calling JSON.stringify().
• Changed the minimum required Node version from v14 to v16.
  • express-rate-limit now targets es2022 in TypeScript/ESBuild.
• Bumped TypeScript from v4 to v5 and dts-bundle-generator from v7 to v8.

Deprecated

• Removed the draft_polli_ratelimit_headers option (it was deprecated in v6).
  • Use standardHeaders: 'draft-6' instead.
• Removed the onLimitReached option (it was deprecated in v6).
  • This is an example of how to replicate it's behavior with a custom handler option.

Changed

• The MemoryStore now uses precise, per-user reset times rather than a global window that resets all users at once.
• The limit configuration option is now prefered to max.
  • It still shows the same behavior, and max is still supported. The change was made to better align with terminology used in the IETF standard drafts.

Added

• The validate config option can now be an object with keys to enable or disable specific validation checks. For more information, see this.
