In Joi, you need to use Joi.object() to instantiate a Joi schema object to work with.Īll schemas require Joi.object()to process validation and other Joi features. Too many methods and API's for doing certain validation in Joi might make you feel overwhelmed so you might end up closing the tab.īut I may be wrong - so let’s keep opinions aside and compare both libraries. Also, I find it easy to understand personally :) This makes this library more niche and provides out of box custom validation and sanitization.

On the other hand, express-validator uses validator.js to validate expressjs routes, and it's mainly built for express.js applications.

It's like a plug n play library and is easy to use.

Joi can be used for creating schemas (just like we use mongoose for creating NoSQL schemas) and you can use it with plain Javascript objects.

Express-validatorĮxpress-validator is a set of express.js middlewares that wraps validator.js validator and sanitizer functions. Joi allows you to create blueprints or schemas for JavaScript objects (an object that stores information) to ensure validation of key information. This comparison is useful when you have decided to use external input validation library for your application built on expressjs and are somewhat not sure which one to use.

In the market, we already have a bunch of validation libraries, but I will compare two important validation libraries: Joi and express-validator for express.js based applications. That's where we use validation to validate inputs and make sure input data follows certain rules. You want to make sure they sign up with real names, not something like cool_dud3. Imagine you have an e-commerce website and you’re allowing users to create accounts using their name and email.
