Hono

Hono  is a small, fast web framework that runs everywhere — Node, Bun, Cloudflare Workers, Deno, edge runtimes. With typia you get one-line request validation that doesn’t ship class-validator or a schema library to the edge.

The integration is @hono/typia-validator. You pass it a createValidate factory result and Hono runs the validator before your handler:

import { Hono } from "hono";
import { typiaValidator } from "@hono/typia-validator";
import typia, { type tags } from "typia";
 
import { IBbsArticle } from "../structures/IBbsArticle";
 
// build a reusable validator from the type
const validate = typia.createValidate<IBbsArticle>();
 
const app = new Hono();
 
app.post("/",
  typiaValidator("json", validate),
  (c) => {
    const data = c.req.valid("json"); // typed as IBbsArticle
    return c.json({
      id: data.id,
      title: data.title,
      body: data.body,
      created_at: data.created_at,
    });
  });
 
export default app;

That’s it. Hono parses the request body, the validator checks it against IBbsArticle (including any tags.Format/tags.MinLength/etc. you attached to the type), and c.req.valid("json") returns the typed value on success.

@hono/typia-validator works for "json", "form", "query", "param", and "header" targets — anywhere Hono accepts a validator.
