ConnInfo Helper

The ConnInfo Helper helps you to get the connection information. For example, you can get the client’s remote address easily.

Import

::: code-group


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


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


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


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


import { Hono } from 'hono'
import { getConnInfo } from 'hono/aws-lambda'


import { Hono } from 'hono'
import { getConnInfo } from 'hono/cloudflare-pages'


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


import { Hono } from 'hono'
import { getConnInfo } from 'hono/lambda-edge'


import { Hono } from 'hono'
import { getConnInfo } from '@hono/node-server/conninfo'

Usage


const app = new Hono()
 
app.get('/', (c) => {
  const info = getConnInfo(c) // info is `ConnInfo`
  return c.text(`Your remote address is ${info.remote.address}`)
})

Type Definitions

The type definitions of the values that you can get from getConnInfo() are the following:


type AddressType = 'IPv6' | 'IPv4' | undefined
 
type NetAddrInfo = {
  /**
   * Transport protocol type
   */
  transport?: 'tcp' | 'udp'
  /**
   * Transport port number
   */
  port?: number
 
  address?: string
  addressType?: AddressType
} & (
  | {
      /**
       * Host name such as IP Addr
       */
      address: string
 
      /**
       * Host name type
       */
      addressType: AddressType
    }
  | {}
)
 
/**
 * HTTP Connection information
 */
interface ConnInfo {
  /**
   * Remote information
   */
  remote: NetAddrInfo
}
