Hi, I'm a new into the Node world, but I'm working in a project where are using a library called Joi for to validate the JSON data came from the request and other things. Then, i decided to search other library, and I found several, than I decided to choose some and create this post, my first post in this community.
Yup
Yup
Yup is a schema builder for runtime value parsing and validation. Define a schema, transform a value to match, assert the shape of an existing value, or both. Yup schema are extremely expressive and allow modeling complex, interdependent validations, or value transformation.
You are viewing docs for the v1.0.0 of yup, pre-v1 docs are available: here
Killer Features:
- Concise yet expressive schema interface, equipped to model simple to complex data models
- Powerful TypeScript support. Infer static types from schema, or ensure schema correctly implement a type
- Built-in async validation support. Model server-side and client-side validation equally well
- Extensible: add your own type-safe methods and schema
- Rich error details, make debugging a breeze
Getting Started
Schema are comprised of parsing actions (transforms) as well as assertions (tests) about the input value Validate an input value to parse it and run the configured set of assertions. Chain together methods to…
Yup is a JavaScript schema builder for value parsing and validation. Define a schema, transform a value to match, validate the shape of an existing value, or both. Yup schema are extremely expressive and allow modeling complex, interdependent validations, or value transformations.
Yup's API is heavily inspired by Joi, but leaner and built with client-side validation as its primary use-case. Yup separates the parsing and validating functions into separate steps. cast() transforms data while validate checks that the input is the correct shape. Each can be performed together (such as HTML form validation) or seperately (such as deserializing trusted data from
APIs).

superstruct
A simple and composable way to validate data in JavaScript (and TypeScript).
A simple and composable way
to validate data in JavaScript (and TypeScript)
Usage • Why? • Principles • Demo • Examples • Documentation
Superstruct makes it easy to define interfaces and then validate JavaScript data against them. Its type annotation API was inspired by Typescript, Flow, Go, and GraphQL, giving it a familiar and easy to understand API.
But Superstruct is designed for validating data at runtime, so it throws (or returns) detailed runtime errors for you or your end users. This is especially useful in situations like accepting arbitrary input in a REST or GraphQL API. But it can even be used to validate internal data structures at runtime when needed.
Usage
Superstruct allows you to define the shape of data you want to validate:
import { assert, object, number, string, array } from 'superstruct'
const Article = object({…Superstruct makes it easy to define interfaces and then validate JavaScript data against them. Its type annotation API was inspired by Typescript, Flow, Go, and GraphQL, giving it a familiar and easy to understand API.
