feat: Introduce ConnInfo helper/adapter

[nakasyou]

I created ConnInfo helper/adapter for Bun, Deno and CF Workers.
You can get client IP Address with Hono easier if we marge PR.

This provides runtime-less ConnInfo object.

For example, you can get IP Address on Bun:

import { Hono } from 'hono'
import { getConnInfo } from 'hono/bun'

const app = new Hono()

app.get('/', c => c.text(`Your ip address is ${getConnInfo(c).remote.address}!!`))

Bun.serve(app)

If you want to use Workers, replace import:

import { getConnInfo } from 'hono/cloudflare-workers'

In Deno:

import { getConnInfo } from 'https://deno.land/x/hono/helper.ts'

Author should do the followings, if applicable

• Add tests
• Run tests
• bun denoify to generate files for Deno

CI fails. Could you run bun run lint:fix (As you said on X, I might have made a mistake in configuring Prettier and ESLint)?

@yusukebe

I ran bun run lint:fix.

If strings include single quote, CI fails due to Prettier or ESLint.

Prettier recommends "it's", but ESLint recommends 'it\'s'

LGTM!

Hey @nakasyou

Looks great! It's finished. This is a new feature, so I'm planning to release it in the next minor release, v4.4. So, I leave this PR not merged yet. Thanks!

@yusukebe, I see. Thanks!

Hello,
I tried to use:

import { getConnInfo } from 'https://deno.land/x/hono/helper.ts'

However, I get the following error. Is this because this is not yet available in v4.3.11? Is there a way I can use this with v4.3.11?

Module '"https://deno.land/x/hono/helper.ts"' has no exported member 'getConnInfo'.deno-ts(2305)

Thank you.

Hi @curioustolearn

Now deno.land/x is not used to publish the Deno module. Use the JSR package instead of it:

import { Hono } from 'jsr:@hono/hono'
import { getConnInfo } from 'jsr:@hono/hono/deno'
