Changelog

All notable changes to the el-form project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[4.2.0] - 2025-08-24

✨ Changes

  • FormSwitch (anchored API): values tuple is now optional. Provide a readonly tuple (as const) to enable compile-time duplicate detection and exhaustiveness checks. No breaking changes.

[4.1.0] - 2025-08-16

✨ New Features

  • Selector-based subscriptions to minimize re-renders

    • New hooks in el-form-react-hooks:
      • useFormSelector(selector, equality?): subscribe to a selected slice of form state
      • useField(path): subscribe to { value, error, touched } for a field path
    • Export shallowEqual for common array/object selector equality
    • SSR-safe snapshots: server snapshot equals client initial selector result
  • FormSwitch optimization (in el-form-react-components)

    • New props: field?: Path<T> and select?: (state) => string | number | boolean
    • Re-renders only when the discriminator changes
    • Deprecated (back-compat for one minor): on and form props; dev-only console.warn

🧪 Examples & Tests

  • Added examples under examples/react/tests demonstrating field, select, back-compat, and useField re-render isolation
  • Added unit tests for selector subscriptions and FormSwitch runtime behavior

📚 Docs

  • Updated Conditional Rendering (FormSwitch) guide to prefer field/select
  • Updated Field Components API for new FormSwitch props
  • Updated useForm API with selector subscription guidance and shallowEqual note
  • Updated useForm API to reflect strict register<Name extends Path<T>> typing (no string fallback). Invalid paths now error; array paths are supported when valid.

[4.0.0] - 2025-08-12

⚠️ Breaking

  • Require zod@^4.0.0. If you are on Zod 3, upgrade with pnpm add zod@^4.

✨ Changes

  • Internal: Zod 4 introspection (no breaking surface changes to AutoForm/useForm APIs).
  • Discriminated unions: more robust introspection; behavior unchanged for users.
  • TypeScript: useForm.register is now type-safe for known paths
    • Literal field names and dot-paths infer exact field value type and return the appropriate props (value, checked, or files).
    • Dynamic string paths remain supported and return a broadly-typed object to preserve backwards compatibility (no app code changes required).
    • Other APIs now accept typed paths where applicable: setValue, watch, resetField.

[3.6.0] - 2025-08-06

✨ New Features

  • Pre-compiled CSS Support: Added optional pre-compiled Tailwind CSS for zero-configuration styling
    • Import "el-form-react-components/styles.css" for instant beautiful forms
    • No Tailwind CSS installation required for end users
    • Backwards compatible - existing Tailwind class approach continues to work
    • 31KB minified CSS with semantic .el-form-* classes
    • Professional gradient buttons, rounded inputs, focus states, and error styling
