What is it?

WireTyped is a small, composable HTTP client for fetch-based runtimes (browser, Node, Bun, Deno, workers). You define your API as typed endpoint definitions and call it with a consistent, error-first API.

Quick taste

import { z } from 'zod'; // Or your standard-schema/spec of choice
import { RequestClient, type RequestDefinitions } from 'wiretyped';
const endpoints = {
  '/users/{id}': {
    get: { response: z.object({ id: z.string(), name: z.string() }) },
  },
} satisfies RequestDefinitions;
const client = new RequestClient({
  hostname: 'https://api.example.com',
  baseUrl: '/api',
  endpoints,
  validation: true,
});
const [err, user] = await client.get('/users/{id}', { id: '123' });
if (err) {
  return err;
}
console.log(user.name);
