📢ArkType 2.2 is here. This is a big one, and it's long overdue. Validated functions, type-safe regex, bidirectional JSON Schema, and universal schema interop. Here's what's new 🧵

Much more: - select + configure — query types by node kind, configure specific references - Improved type.declare — morph-aware declarations, optionality via property values - type.or, type.and, type.merge, type.pipe — n-ary standalone operators - "|>" string-embeddable pipe syntax - type.valueOf for TS enums - string.hex + string.regex keywords - Serializable ArkErrors (flatByPath, flatProblemsByPath, toJSON) - exactOptionalPropertyTypes config - ES2020 + Hermes compatibility - In-docs playground

Standard Schema validators can now be embedded directly in ArkType definitions. Zod, Valibot, or anything else that implements the spec.

@ark/json-schema — Bidirectional JSON Schema Parse JSON Schema into ArkType Types, and convert Types to JSON Schema. Huge thanks to @TizzySaurus for building this one. toJsonSchema() now supports configurable fallbacks, draft-07/2020-12 targets, and cyclic types. 11 granular fallback codes for handling incompatibilities your way.

all you need to "learn" ArkType syntax: 1️⃣ start with a typescript keyword 2️⃣ .autocomplete to discover constraints 3️⃣ compose if needed with &, |, etc.
