Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited community support and small user base

   GitHub repository has low activity and limited contributions from the community.

2. 02

   Poor documentation for complex use cases

   The official documentation lacks examples and explanations for advanced validation scenarios, leading to a steep learning curve.

3. 03

   Performance issues with large datasets

   Superstruct can become slow when validating large or deeply nested data structures due to its recursive nature.

4. 04

   Limited built-in validators, requiring custom implementations

   The library provides a basic set of validators and often requires developers to write their own for more complex validation logic.

What it does well

• Simple and composable data validation structures.

• Support for both JavaScript and TypeScript.

• Extensible with custom validators.

• Lightweight and easy to integrate into projects.
