Zod finally has competition (...created by Zod?)

What is Zod and why has it been popular?

Zod is a powerful TypeScript library designed to provide runtime validation for JavaScript objects. Its versatility and effectiveness have made it a favorite among TypeScript developers. Over recent years, Zod has gained tremendous popularity in the community due to its capability to seamlessly integrate validation directly into TypeScript environments.

One of the stand-out features of Zod is its ability to validate various data types, including strings, numbers, and more complex structures.

This allows developers to perform detailed checks, like ensuring a string falls within a specific length range or that numbers are within certain limits.

The library's flexibility even extends to advanced options, such as custom validators, making it adaptable to a broad spectrum of requirements.

The user-friendly API elevates the ease of implementing robust input validation, which is a core reason for its widespread adoption and trusted use in multiple projects.

What limitations did Zod face?

• Speed: Zod is not recognized for being the fastest validator on the market.

• TypeScript Performance: It has some notable performance issues when used with TypeScript.

• Adherence to Standards: Zod doesn't fully comply with existing validation standards, leading to limitations in some use cases.

These constraints highlight the need for improvements and adaptations within TypeScript validation frameworks.

What is the new standard schema reference?

The new standard schema reference was introduced by Colin. It represents a significant step forward in TypeScript validation by enabling compatibility across different libraries like Zod, Valleybot, and Archetype.

This innovative schema acts as a universal reference, serving as a bridge between various validation libraries.

Rather than being library-specific, the standard schema works with any library that opts to adopt it.

This results in a versatile solution allowing developers to swap between libraries seamlessly without needing to rewrite code.

By supporting multiple libraries, the standard schema reference minimizes conflicts and inconsistencies, empowering developers to choose the best tool for their needs. Its introduction marks a new era in validation, promising a smoother, more cohesive development experience for TypeScript developers.

In essence, it's a game-changing development that brings harmony to the diverse landscape of TypeScript validation libraries.

How does the standard schema benefit TypeScript developers?

1. Seamless Library Switching: The introduction of the standard schema reference allows developers to easily switch between TypeScript validation libraries. This flexibility eliminates the need for extensive code rewrites when opting for different libraries like Zod, Valleybot, or Archetype.

2. Enhanced Validation Integration: With a unified schema, TypeScript developers can achieve smooth integration across multiple libraries. This is crucial for maintaining consistency and minimizing conflicts within a codebase.

3. Broader Compatibility: The standard schema ensures compatibility with various frameworks, reducing the friction previously experienced when different validation standards were involved.

4. Future-Proof Development: Adopting the standard schema reference means developers are better prepared for future updates and library innovations. This adaptability ensures that projects remain robust and scalable over time.

Including these enhanced capabilities, the new standard schema harmonizes the diverse landscape of TypeScript validation, promising a more cohesive development experience.

Which libraries and frameworks support the new standard?

Several libraries and frameworks have already embraced the new standard schema reference, enhancing compatibility and flexibility for TypeScript developers.

• TRPC: Originally built around Zod, it now supports multiple validators seamlessly.

• TanStack Form: Enables easy swapping between different validation libraries with no extra effort.

• OpenAuth: Offers a standardized validation experience, reducing dependency issues.

• TanStack Router: Integrates with the standard schema for consistent validation across routing.

• Upload Thing and T3 Environment: These tools emphasize robust validation practices by incorporating the new schema.

This growing list showcases the widespread adoption and benefits of the standard schema across the TypeScript ecosystem.
