typewriter-typescript

TypeScript emitter for the typewriter SDK.

What It Generates

For each Rust type targeting TypeScript, this crate generates:

<type>.ts with static TypeScript interfaces/types
<type>.schema.ts with runtime Zod schemas

Rust	TypeScript
`struct`	`export interface` + `export const NameSchema = z.object(...)`
Simple `enum`	String literal union + `z.enum([...])`
Tagged `enum`	Discriminated union + `z.discriminatedUnion(...)`
`Option<T>`	`field?: T \| undefined` + `.optional()`
`Vec<T>`	`T[]` + `z.array(...)`
`HashMap<K,V>`	`Record<K, V>` + `z.record(...)`

Example Output

// user-profile.ts
export interface UserProfile {
  id: string;
  email: string;
  age?: number | undefined;
  tags: string[];
}

// user-profile.schema.ts
import { z } from 'zod';

export const UserProfileSchema = z.object({
  "id": z.string(),
  "email": z.string(),
  "age": z.number().optional(),
  "tags": z.array(z.string()),
});

Runtime Dependency

Generated schema files import from zod:

npm install zod

Usage

Used internally by typewriter-macros. Most users should depend on the main typewriter crate.
