## Install
|
|
|
|
```bash
|
|
$ npm install @sinclair/typemap --save
|
|
```
|
|
|
|
## Example
|
|
|
|
Use syntax to construct types for TypeBox, Valibot and Zod ...
|
|
|
|
```typescript
|
|
import { TypeBox, Zod, Valibot } from '@sinclair/typemap'
|
|
|
|
// const T: TObject<{ ... }>
|
|
|
|
const T = TypeBox(`{
|
|
x: number,
|
|
y: number,
|
|
z: number
|
|
}`)
|
|
|
|
// const V: ObjectSchema<{ ... }>
|
|
|
|
const V = Valibot(`{
|
|
x: number,
|
|
y: number,
|
|
z: number
|
|
}`)
|
|
|
|
// const Z: ZodObject<{ ... }>
|
|
|
|
const Z = Zod(`{
|
|
x: number,
|
|
y: number,
|
|
z: number
|
|
}`)
|
|
```
|
|
|
|
... or structurally remap types from one library to another
|
|
|
|
```typescript
|
|
import { TypeBox, Valibot, Zod } from '@sinclair/typemap'
|
|
|
|
// Syntax > Zod > Valibot > TypeBox
|
|
|
|
const T = TypeBox(Valibot(Zod(`{
|
|
x: number,
|
|
y: number,
|
|
z: number
|
|
}`)))
|
|
```
|
|
|
|
... or compile types for high performance runtime type checking
|
|
|
|
```typescript
|
|
import { Compile } from '@sinclair/typemap'
|
|
|
|
import z from 'zod'
|
|
|
|
const T = z.object({ // const T: z.ZodObject<{
|
|
x: z.number(), // x: z.ZodNumber,
|
|
y: z.number(), // y: z.ZodNumber,
|
|
z: z.number(), // z: z.ZodNumber,
|
|
}) // }>
|
|
|
|
const C = Compile(T) // const C: Validator<TObject<{
|
|
// x: TNumber,
|
|
// y: TNumber,
|
|
// z: TNumber
|
|
// }>>
|
|
|
|
const R = C.Check({ // const R: boolean - High Performance Checking!
|
|
x: 1,
|
|
y: 2,
|
|
z: 3
|
|
})
|
|
```
|
|
|

## Overview
|
|
|
|
TypeMap is an type mapping library developed for TypeBox, Valibot and Zod. It enables quick compatibility between each library by structurally remapping type representations from one library to another. In addition,TypeMap offers a uniform syntax for type construction as well as high-performance runtime type checking for Valibot and Zod via the TypeBox compiler infrastructure.
|
|
|
|
TypeMap is designed to be a simple tool to enable Valibot and Zod to integrate with TypeBox and Json Schema validation infrastructure. It is also written to allow TypeBox to integrate with systems leveraging Valibot and Zod for validation. The frontend syntax provided by TypeMap seeks to explore a uniform API surface for runtime type libraries.

## Libraries
|
|
|
|
TypeMap exports mapping functions named after the library they map for. Each function can accept a type from any other library, where the function will attempt to map the type or return a `never` representation if a mapping is not possible.
|
|
|
|
### TypeBox
|
|
|
|
Use the TypeBox function to map the parameter into a TypeBox type
|
|
|
|
```typescript
|
|
import { TypeBox } from '@sinclair/typemap'
|
|
|
|
const A = TypeBox(t.Number()) // const A: TNumber (TypeBox)
|
|
const B = TypeBox(v.string()) // const B: TString (Valibot)
|
|
const C = TypeBox(z.boolean()) // const C: TBoolean (Zod)
|
|
const D = TypeBox('string[]') // const D: TArray<TString> (Syntax)
|
|
```
|
|
|
|
### Valibot
|
|
|
|
Use the Valibot function to map the parameter into a Valibot type
|
|
|
|
```typescript
|
|
import { Valibot } from '@sinclair/typemap'
|
|
|
|
const A = Valibot(t.Number()) // const A: v.NumberSchema (TypeBox)
|
|
const B = Valibot(v.string()) // const B: v.StringSchema (Valibot)
|
|
const C = Valibot(z.boolean()) // const C: v.BooleanSchema (Zod)
|
|
const D = Valibot('string[]') // const D: v.ArraySchema<...> (Syntax)
|
|
```
|
|
|
|
### Zod
|
|
|
|
Use the Zod function to map the parameter into a Zod type
|
|
|
|
```typescript
|
|
import { Zod } from '@sinclair/typemap'
|
|
|
|
const A = Zod(t.Number()) // const A: z.ZodNumber (TypeBox)
|
|
const B = Zod(v.string()) // const B: z.ZodString (Valibot)
|
|
const C = Zod(z.boolean()) // const C: z.ZodBoolean (Zod)
|
|
const D = Zod('string[]') // const D: z.ZodArray<...> (Syntax)
|
|
```
|
|
|
|
## Static
|
|
|
|
TypeMap can statically infer for TypeBox, Valibot, Zod and Syntax with the `Static` type.
|
|
|
|
```typescript
|
|
import { type Static } from '@sinclair/typemap'
|
|
|
|
const T = t.Number() // TypeBox
|
|
const V = v.string() // Valibot
|
|
const Z = z.boolean() // Zod
|
|
const S = 'string[]' // Syntax
|
|
|
|
type T = Static<typeof T> // number
|
|
type V = Static<typeof V> // string
|
|
type Z = Static<typeof Z> // boolean
|
|
type S = Static<typeof S> // string[]
|
|
```
|
|
|
|
## Compile
|
|
|
|
TypeMap offers JIT compilation of TypeBox, Valibot, Zod and Syntax using the `Compile` function. This function will internally use the TypeBox TypeCompiler for high performance checking. This function will also gracefully degrade to dynamic checking if the runtime does not support JavaScript evaluation.
|
|
|
|
The `Compile` function returns a validator object that implements the [standard-schema](https://github.com/standard-schema/standard-schema) interface.
|
|
|
|
```typescript
|
|
import { Compile } from '@sinclair/typemap'
|
|
|
|
// Pass TypeBox, Valibot, Zod or Syntax to JIT Compile the type.
|
|
const V = Compile(`{
|
|
x: number
|
|
y: number,
|
|
z: number
|
|
}`)
|
|
|
|
// TypeMap Interface
|
|
const R1 = V.Check({ x: 1, y: 2, z: 3 })
|
|
|
|
// Standard Schema Interface
|
|
const R2 = V['~standard'].validate({ x: 1, y: 2, z: 3 })
|
|
```
|
|
|
|
## Benchmark
|
|
|
|
This project manages a benchmark that evaluates type-check performance using Zod, Valibot, and TypeBox validators. The benchmark is set up to run 10 million check operations per library-validator pairing and reports the elapsed time taken to complete.
|
|
|
|
### Type
|
|
|
|
Benchmarks are run for the following type.
|
|
|
|
```typescript
|
|
type T = { x: number, y: string, z: boolean }
|
|
```
|
|
|
|
### Results
|
|
|
|
Results show validate performance for the type.
