Express application used for Captcha creation and validation. It uses Redis as a storage for captchas since the service does not store the captcha image but only its correct word together with its key (and for the sake of simplicity).

• run docker-compose up -d to start both Redis container and captcha service container
• captcha service will be listening at http//localhost:3000
• see openapi.yml for endpoints documentation

You can also pull the image with docker pull mattiadevivo/captcha:latest since the image is deployed in a public DockerHub repo.

Copy and paste the captchaImage value from json body of POST captchas/ response and paste it here (do not include ").

Test are written using mocha (and chai as assertion library) and resides under test folder. You can run tests using npm run test (first install dependencies using npm install).
