🆕 What's New in v4 ​
v4 adds TypeScript support directly into the existing drea package. There is no separate edition to install — TypeScript users get types automatically on npm install drea@4.
| Area | Before v4 | v4 |
|---|---|---|
| TypeScript types | Not included | Bundled — import { ... } from 'drea' just works |
| Type-narrowing guards | Not available | asserts value is T on every guard |
| Generic models | Not available | validate<T> / nestvalidate<T> — result type inferred from input |
| File validation | Not available | __File() wrapper — prevents nestvalidate recursing into File objects |
| Guard system | Manual null/type checks per function | Dedicated named guard on every public surface |
| Error descriptions | Inconsistent | Always "Expected X for 'paramName', got Y" |
