Any reverse proxy middleware for hyper express?
I look up online didn't find something

Hi @ahmaddie1378

Maybe you can try such a method by deriving it and adapting it to your structure:

import * as HyperExpress from 'hyper-express'
import axios from 'axios'

let server = new HyperExpress.Server()
let router = new HyperExpress.Router()

const service = {
  host: '0.0.0.0',
  port: 3001,
  prefix: 'auth',
  protocol: 'http',
}
const proxyMiddleware = async (req: any, res: any) => {
  const target = `${service.host}:${service.port}`
  const targetUrl = `${service.protocol}://${target}${req.url.replace(`/api/${service.prefix}`, '')}`

  console.log(`Proxying request to ${targetUrl}`)

  try {
    const response = await axios({
      method: req.method,
      url: targetUrl,
      headers: req.headers,
      data: req.body,
    })

    res.status(response.status)
    Object.entries(response.headers).forEach(([key, value]) => {
      res.setHeader(key, value)
    })
    res.send(response.data)
  } catch (error) {
    console.error('Proxy error:', error)
    res.status(500).send('Internal Server Error')
  }
}

router.get('/', (req, res) => {
  res.send('Base Route')
})

router.get('/v1', (req, res) => {
  res.send('API')
})

router.use(`/v1/service`, async (req, res) => {
  await proxyMiddleware(req, res)
})

router.all('*', (req, res) => {
  res.status(404).send('404 Not Found')
})

server
  .use(router)
  .listen(3000)
  .then((socket) => {
    console.log('App started on port: 3000')
  })
  .catch((error) => console.log('Failed to start webserver;' + error))
