Example of validating express request body:

const Joi = require('joi');

const validateRequest = (schema) => async (req, res, next) => {
    const { error } = Joi.validate(req.body, schema);

    if (error) {  
      throw new Error(error);
    }

    return next();
  };

const validatinSchema =  Joi.object().keys({
    firstName:  Joi.string().required(),
    lastName: Joi.string().required(),
  }),

router.post('/', validateRequest(validationSchema), async (req, res) =>
 // rest of your code
