Handling Compressed Requests

import { gunzipSync } from 'node:zlib'

Deno.serve(async (req) => {
  try {
    // Check if the request body is gzip compressed
    const contentEncoding = req.headers.get('content-encoding')
    if (contentEncoding !== 'gzip') {
      return new Response('Request body is not gzip compressed', {
        status: 400,
      })
    }

    // Read the compressed body
    const compressedBody = await req.arrayBuffer()

    // Decompress the body
    const decompressedBody = gunzipSync(new Uint8Array(compressedBody))

    // Convert the decompressed body to a string
    const decompressedString = new TextDecoder().decode(decompressedBody)
    const data = JSON.parse(decompressedString)

    // Process the decompressed body as needed
    console.log(`Received: ${JSON.stringify(data)}`)

    return new Response('ok', {
      headers: { 'Content-Type': 'text/plain' },
    })
  } catch (error) {
    console.error('Error:', error)
