TypeBox-Codegen

Code Generation Tools for TypeBox

Install

npm install @sinclair/typebox-codegen

Example

import * as Codegen from '@sinclair/typebox-codegen'

const Code = Codegen.TypeScriptToTypeBox.Generate(`
  type T = { x: number, y: number, z: number }
`)

console.log(Code)

// Output:
//
// import { Type, Static } from '@sinclair/typebox'
// 
// type T = Static<typeof T>
// const T = Type.Object({
//   x: Type.Number(),
//   y: Type.Number(),
//   z: Type.Number()
// })

Overview

TypeBox-Codegen is a code generation tool that converts TypeScript types into TypeBox types as well as several other schema and library representations. It works by extracting structural type information from the TypeScript compiler then remaps it into a TypeBox representation (referred to as a Model). This Model can then be passed on to various code generators which generate through TypeBox schema introspection.

The library contains code transformations for libraries such as zod, io-ts, arktype and valibot, assert function generators for JavaScript and TypeScript (derived from TypeBox's TypeCompiler) as well as JSON Schema derived from TypeBox's raw schematics.

Usage

The following is the general usage

import * as Codegen from '@sinclair/typebox-codegen'

const Code = `
export type T = {
  x: number,
  y: number,
  z: number
}
`
// ----------------------------------------------------------------------------
//
// TypeScriptToTypeBox
//
// Generates an immediate TypeScript to TypeBox type code transformation
//
// ----------------------------------------------------------------------------

console.log('TypeScript To TypeBox', Codegen.TypeScriptToTypeBox.Generate(Code))

// ----------------------------------------------------------------------------
//
// TypeScriptToModel
//
// Generates an in-memory TypeBox Model
//
// ----------------------------------------------------------------------------

const model = Codegen.TypeScriptToModel.Generate(Code)

// ----------------------------------------------------------------------------
//
// ModelToX
//
// The TypeBox Model can be passed to several generators which map the
// Model into varying type representations.
//
// ----------------------------------------------------------------------------

console.log('TypeBoxModel', model)
console.log('Model To JsonSchema', Codegen.ModelToJsonSchema.Generate(model))
console.log('Model To JavaScript', Codegen.ModelToJavaScript.Generate(model))
console.log('Model To TypeScript', Codegen.ModelToTypeScript.Generate(model))
console.log('Model To Valibot', Codegen.ModelToValibot.Generate(model))
console.log('Model To Value', Codegen.ModelToValue.Generate(model))
console.log('Model To Yup', Codegen.ModelToYup.Generate(model))
console.log('Model To Zod', Codegen.ModelToZod.Generate(model))
console.log('Model To ArkType', Codegen.ModelToArkType.Generate(model))
