Instructions

Step 1: Configure GitHub Webhook Receiver

import express from "express";
import crypto from "crypto";

const app = express();

app.post("/webhooks/github",
  express.raw({ type: "application/json" }),
  async (req, res) => {
    const signature = req.headers["x-hub-signature-256"] as string;  # 256 bytes
    const secret = process..!;

     expected =  + crypto
      .(, secret)
      .(req.)
      .();

     (!crypto.(.(signature), .(expected))) {
       res.().({ :  });  #   
    }

     event = req.[]  ;
     payload = .(req..());
    res.().({ :  });  #   
     (event, payload);
  }
);
