Discussion on: A Clean Approach to Using Express Validator

const { body, validationResult} = require('express-validator');

const validate = (schemas)  => {
    return async (req, res, next) => {
      await Promise.all(schemas.map((schema) => schema.run(req)));

      const result = validationResult(req);
      if (result.isEmpty()) {
        return next();
      }

      const errors = result.array();
      return  res.send(errors)
    };
  }
 const exampleSchema = [
   body('foo', 'The foo field is required').notEmpty(),
   ...
];

router.post('/foos', validate(exampleSchema), fooHandler);
