express-recaptcha

Express middleware for Google reCAPTCHA integration (v2 and v3). Current stable version is 5.1.0, with TypeScript support added in v4.0.0. The library provides simple middleware methods to render captcha widgets and verify tokens. v3.0.0 introduced breaking changes: the module now exports a class constructor instead of an instance, the 'recaptcha' property is set on the response object rather than the request, and the verify result format changed. Alternative packages include 'recaptcha-v2' and 'google-recaptcha', but express-recaptcha offers a straightforward express-centric API.
