DenoとHonoでWebアプリ、ユニットテストも軽く書いたやつ

app.test.ts

import { assertEquals } from 'std/testing/asserts.ts';
import { app } from './app.ts';

Deno.test('Should be HTTP status is 200', async () => {
    // Request URL must be an absolute path
    const res = await app.request('http://localhost:8000/');
    
    // assert
    assertEquals(res.status, 200);
});

app.ts

import { Hono } from "hono/mod.ts";

export const app = new Hono();

app.get('/', (c) => c.text('Hello! Hono!'));

deno.jsonc

{
    // import map
    "importMap": "import_map.json",
    // tasks
    "tasks": {
        "start": "deno run --allow-net ./main.ts"
    }
}

import_map.json

{
    "imports": {
        "std/": "https://deno.land/std@0.166.0/",
        "hono/": "https://deno.land/x/hono@v2.5.2/"
    }
}

main.ts

import { serve } from "std/http/server.ts";
import { app } from "./app.ts";

await serve(app.fetch);
