CAPTCHA API

My blog post: Let's Build a CAPTCHA Generator with Node.js

🔒 Keep those nasty bots out with a home-grown CAPTCHA!

Install

npm i

Run

npm start

API

All routes default to 200x100 size unless specified.

• /test/:width?/:height?/

  • Get a web page with an image element to manually test the API.

• /captcha/:width?/:height?/

  • Get a CAPTCHA object for proper usage.
  • { "image": <data url>, "text": <validation text> }

Test

Uses Jest to run integration tests.

npm test

n.b. CAPTCHAs are not accessible and in some cases not even effective.
