Study Notes
- A validation chain is a subset of the Sanitization Chain, which means all standard sanitizers and its additional methods are available.
- Additional methods include .isArray, .isObject, and .isString.
- The .bail() method can be used to prevent a custom validator from running when you know it will fail.
- You can add a validator to the current validation chain by calling .custom().
- The .exists() validator checks for the existence of the current fields in the request.
- You can customize this behavior by passing an object with the .if() and .withMessage() options.
