turbo-response

A TypeScript library providing a type-safe Result type (Success/Fail) for handling operation outcomes.

Installation

npm install turbo-response

Features

• Type-safe result handling with discriminated unions
• Comprehensive API for working with success and failure states
• Zero dependencies (except dev dependencies)
• Full TypeScript support with complete type inference
• Functional programming utilities for chaining and transforming results

Quick Start

import { success, fail, fold, TurboResponse } from 'turbo-response';

// Creating responses
const successResult = success({ id: '123', name: 'John' });
const failResult = fail(new Error('Not found'));

// Pattern matching
const message = fold(
  response,
  (data) => `Found user: ${data.name}`,
  (error) => `Error: ${error.message}`
);

// Chaining operations
const result = await andThenAsync(
  fetchUser('123'),
  async (user) => fetchOrders(user.id)
);
