TypeScript language extension for Atscript. Compiles .as files to .d.ts type declarations and .js runtime modules with validation, serialization, and JSON Schema support. Includes the asc CLI.

Installation

pnpm add @atscript/typescript @atscript/core

Quick Start

# Compile .as files to .d.ts + .js
npx asc -f js

# Diagnostics only
npx asc --noEmit

// Runtime validation
import { buildJsonSchema } from '@atscript/typescript/utils'
import { User } from './schema/user.as'

User.validator().validate(inputData) // throws on failure
const schema = buildJsonSchema(User.annotatedType)

Features

• Generates .d.ts type declarations and .js runtime modules from .as files
• CLI (asc) for batch compilation with diagnostics
• Validator class for runtime data validation against @expect.* constraints
• JSON Schema generation (buildJsonSchema) and parsing (fromJsonSchema)
• Serialization for JSON-safe round-trip of type definitions
• Type-safe utility types: FlatOf<T>, PrimaryKeyOf<T>, OwnPropsOf<T>, NavPropsOf<T>
• Global atscript.d.ts generation for typed metadata access
