Hono Rpc

Hono RPC - Type-Safe Client

Overview

Hono RPC enables sharing API specifications between server and client through TypeScript's type system. Export your server's type, and the client automatically knows all routes, request shapes, and response types - no code generation required.

Key Features:

• Zero-codegen type-safe client
• Automatic TypeScript inference
• Works with Zod validators
• Status code-aware response types
• Supports path params, query, headers

When to Use This Skill

Use Hono RPC when:

• Building full-stack TypeScript applications
• Need type-safe API consumption without OpenAPI/codegen
• Want compile-time validation of API calls
• Sharing types between client and server in monorepos

Basic Setup

Server Side

// server/index.ts
import { Hono } from 'hono'
import { zValidator } from '@hono/zod-validator'
import { z } from 'zod'

const app = new Hono()
