User Story 10 - Incorporate middleware to verify params

[alexanderjhughes]

Use the Joi library to validate params:

import Joi from 'joi';

const validateCardParams = (req, res, next) => {
  const schema = Joi.object({
    card_id: Joi.number().required(),
    card_bin: Joi.number().required(),
  });

  const { error } = schema.validate(req.params);

  if (error) {
    res.status(400).json({ message: error.details[0].message });
    return;
  }

  next();
};

// Then use it in your route
app.get('/card', validateCardParams, CardController.getCard);
