Getting Started

Zagora enables building type-safe and error-safe procedures that encapsulate business logic with robust validation, error handling, and context management.

What is Zagora?

Zagora is a minimalist TypeScript library for creating type-safe, error-safe functions that never throw. Unlike oRPC or tRPC, Zagora focuses on producing pure functions—no network layer, no routers, just regular TypeScript functions with superpowers.

Key Features

• Full Type Inference - Complete TypeScript inference across inputs, outputs, errors, and context
• Never Throws - Every function returns { ok, data, error } for predictable execution
• Tuple Arguments - Define multiple function arguments with per-argument validation
• Sync & Async - Dynamic inference based on handler behavior
• StandardSchema - Works with Zod, Valibot, ArkType, and any compliant validator

Installation

bun add zagora

Quick Start

import { z } from 'zod';
import { zagora } from 'zagora';
 
const greet = zagora()
  .input(z.string())
  .handler((_, name) => `Hello, ${name}!`)
  .callable();
 
const result = greet('World');
if (result.ok) {
  console.log(result.data); // "Hello, World!"
}
