How does joi.binary work?

joi.binary() is a method in the Joi library that creates a schema for validating binary data inputs, specifying their minimum and maximum byte lengths, and accepting specific formats such as "base64" or "hex". When used to validate data, it returns an error if the input is not valid.

    } /*,

const Joi = require("joi");

const schema = Joi.object({
  id: Joi.number().required(),
  file: Joi.binary().required(),
});

const data = {
  id: 123,
  file: Buffer.from("Hello World!"),
};

const result = schema.validate(data);
if (result.error) {
  console.log(result.error.details);
} else {
  console.log("Data is valid");
}

In this example, we define a schema using Joi.object() and set the file property to be a binary data type using Joi.binary(). We then create some data that includes a Buffer object for the file property and validate it against the schema using schema.validate(). If there is an error, we log it; otherwise, we log that the data is valid.
