Any way to access raw body?

[roycejewell]

I cannot for the life of me access the raw body of a serverless function to sign a webhook.

import type { VercelRequest, VercelResponse } from '@vercel/node';
import type { Readable } from 'node:stream';

export const config = {
  api: {
    bodyParser: false,
  },
};

async function buffer(readable: Readable) {
  const chunks = [];
  for await (const chunk of readable) {
    chunks.push(typeof chunk === 'string' ? Buffer.from(chunk) : chunk);
  }
  return Buffer.concat(chunks);
}

export default async function (req: VercelRequest, res: VercelResponse) {
  if (req.method === 'POST') {
    const buf = await buffer(req);
    const rawBody = buf.toString('utf8');

    // Can do something here...
    res.json({ rawBody });
  } else {
    res.setHeader('Allow', 'POST');
    res.status(405).end('Method Not Allowed');
  }
}
