@react-types/form

This package is purely TypeScript type definitions for Adobe's React Spectrum form components. There's no runtime code, which means virtually no attack surface—a major win from a security perspective. You're getting well-structured interface definitions for form events, validation states, and input properties that integrate cleanly with React Spectrum's form handling.

In practice, the types are comprehensive and catch common form-related bugs at compile time. The validation state typing helps prevent unsafe data handling patterns, and the event types ensure you're properly sanitizing inputs before submission. Since it's just types, dependency supply chain risk is minimal—no transitive dependencies pulling in crypto libraries or network code that could introduce vulnerabilities.

The main limitation is tight coupling to React Spectrum's ecosystem. If you're already using Spectrum components, these types are essential and work seamlessly. The type definitions don't enforce secure defaults at runtime (that's your responsibility), but they provide good guardrails for implementing proper validation and error handling patterns.

This package provides TypeScript type definitions for form-related components in Adobe's React Spectrum design system. In daily use, the types are comprehensive and accurate, covering all props for TextField, TextArea, Checkbox, RadioGroup, and other form primitives. The autocomplete experience in VS Code and other IDEs is excellent—you get immediate feedback on valid prop names, value types, and event handlers.

The types integrate seamlessly with React Spectrum's prop system, including support for ARIA props, validation states, and accessibility features. Event handlers are properly typed with specific payload types rather than generic events, which catches errors at compile time. The onChange signatures particularly shine with their clear discrimination between controlled and uncontrolled patterns.

The main friction point is that this is purely a types package with zero runtime code or documentation. You need to reference the main React Spectrum docs to understand what these props actually do. There's also some version coordination needed—ensure your @react-types/form version aligns with your @adobe/react-spectrum version to avoid type mismatches during upgrades.

This is a pure TypeScript definitions package for Adobe's React Spectrum form components. In practice, it's a dependency you'll rarely interact with directly—it gets pulled in when you use @react-spectrum/form or related components. The types are well-structured and comprehensive, providing excellent autocomplete and compile-time validation for form props, events, and validation patterns.

From a security perspective, this package is low-risk since it contains only TypeScript declarations with no runtime code. The Apache-2.0 license from Adobe is enterprise-friendly, and the package is actively maintained as part of the larger React Spectrum ecosystem. The type definitions enforce proper patterns for input validation callbacks and error handling, which helps prevent common security mistakes at the type level.

One practical benefit: the types clearly distinguish between controlled and uncontrolled form patterns, reducing bugs around state management. However, you're locked into Adobe's component architecture—if you need custom form implementations, these types won't help much. The package follows secure-by-default principles by making validation and error handling explicit in the type signatures.
