nestjs-platform-hono

NestJS HTTP adapter for Hono🔥

Installation

$ deno add jsr:@uki00a/nestjs-platform-hono jsr:@hono/hono npm:@nestjs/common npm:@nestjs/core

Usage

Setup an application

import { NestFactory } from "@nestjs/core";
import type { NestHonoApplication } from "@uki00a/nestjs-platform-hono";
import { HonoAdapter } from "@uki00a/nestjs-platform-hono";
import { AppModule } from "@/app.module.ts";

const app = await NestFactory.create<NestHonoApplication>(
  AppModule,
  HonoAdapter.create(),
);

Start the application

await app.listen(8000);

Advanced features

Integration with hono/jsx

To use the integration with hono/jsx, you should add the following to deno.json:

{
  "compilerOptions": {
    "jsx": "precompile",
    "jsxImportSource": "@hono/hono/jsx"
    // ...
  }
  // ...
}

Then apply @Html() decorator to an action method that returns JSX:

import { Html } from "@uki00a/nestjs-platform-hono";
import { Controller, Get } from "@nestjs/common";

@Controller("/")
export class ViewController {
  @Html()
  @Get("/")
  home() {
    return (
      <html>
        <body>
          <div>{"Hello hono/jsx!"}</div>
        </body>
      </html>
    );
  }
}

Limitations

@Body() decorator does not work

If a request body is needed, you should use @JsonBody() decorator instead:

import { Controller, Post } from "@nestjs/common";
import { JsonBody } from "@uki00a/nestjs-platform-hono";

@Controller("/tags")
export class TagsController {
  @Post()
  createTag(@JsonBody("name") tagName: string) {
    return { name: tagName };
  }
}
