Valibot - Effortless type safety and validation

Valibot operates by leveraging the robust type system inherent in TypeScript. This library allows developers to define schemas that represent the structure of data they expect. When data is validated against these schemas, Valibot processes the incoming data, checks it against the defined types, and ensures that all properties conform to specified types. This leads to less runtime errors and enhances application reliability. The functionality can be broken down into the following key components:

• Type Safety: Guarantees that data adheres strictly to the defined types.
• Static Type Inference: Automatically infers types based on provided schemas, reducing boilerplate code.
• Modular Design: Keeps the bundle size low while allowing custom imports of necessary modules.
• Validation: Validates various TypeScript types, including primitive values and complex structures.
• Test Coverage: Ensures that all functionalities are thoroughly tested and reliable for production use.
• Built-in Helpers: Offers various utility functions for common tasks, improving efficiency while coding.

Getting started with Valibot is straightforward. Begin by installing the library using npm or yarn. In your TypeScript project, run the following command:

npm install valibot

Once installed, import Valibot in your TypeScript files to start defining your type schemas. Here's a simple example to illustrate how you can use Valibot:

import { createValidator } from 'valibot';

// Define your schema
type User = { name: string; age: number; };

const userSchema = createValidator<User>();

// Validate data against the schema
const userData = { name: 'John Doe', age: 30 };
const isValid = userSchema.validate(userData);

if (isValid) {
  console.log('Valid user data!');
} else {
  console.log('Invalid user data!');
}

This code snippet demonstrates how easily you can define a schema for a User type and validate data against it. By utilizing Valibot, developers can ensure their application's data is consistently structured, reducing runtime errors and enhancing maintainability.

Lastly, don’t forget to visit the Playground to experiment with Valibot in a hands-on environment where you can test different schemas and validations.

In summary, Valibot is a powerful tool for TypeScript developers looking to enhance their applications with type safety and validation capabilities. Its open-source nature, small bundle size, and a user-friendly API make it an excellent choice for both experienced developers and newcomers alike. With Valibot, you can validate unknown data confidently, ensuring your applications are reliable and maintainable. Explore Valibot today at valibot.dev!
