Follow the official Deno installation guide.

Start a new project with:

deno init --npm hono my-app
cd my-app

Select the deno template if prompted.

Create val
import { Hono } from 'hono'

const app = new Hono()

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

Deno.serve(app.fetch)

deno task start

Specify a port in main.ts:

Create val
Deno.serve({ port: 8787 }, app.fetch)

Use serveStatic from hono/deno:

Create val
import { Hono } from 'hono'
import { serveStatic } from 'hono/deno'

const app = new Hono()

app.use('/static/*', serveStatic({ root: './' }))
app.use('/favicon.ico', serveStatic({ path: './favicon.ico' }))
app.get('/', (c) => c.text('You can access: /static/hello.txt'))
app.get('*', serveStatic({ path: './static/fallback.txt' }))

Deno.serve(app.fetch)

You can customize static file serving with options like rewriteRequestPath, mimes, onFound, onNotFound, and precompressed.

Write tests using Deno's built-in test runner:

Create val
import { Hono } from 'hono'
import { assertEquals } from '@std/assert'

Deno.test('Hello World', async () => {
  const app = new Hono()
  app.get('/', (c) => c.text('Please test me'))

  const res = await app.request('http://localhost/')
  assertEquals(res.status, 200)
})

Run with:

deno test hello.ts

You can use either jsr:@hono/hono or npm:hono in your deno.json imports:

{
  "imports": {
    "hono": "jsr:@hono/hono"
  }
}

Or for npm:

{
  "imports": {
    "hono": "npm:hono",
    "zod": "npm:zod",
    "@hono/zod-validator": "npm:@hono/zod-validator"
  }
}
