Override javascript error fingerprint for Honeybadger

honeybadger.js

import Honeybadger from "@honeybadger-io/js";

const honeybadger = Honeybadger.configure({
  apiKey: "your-api-key",
});

// Function to generate a SHA-256 hash in pure JavaScript
async function generateFingerprint(stackFrame) {
  const { file, line, method } = stackFrame;

  try {
    // Extract the file path without the domain
    const url = new URL(file);
    const filePath = url.pathname; // Removes protocol and domain

    // Concatenate the relevant data
    const fingerprintData = `${filePath}:${line}:${method}`;

    // Convert to a Uint8Array
    const encoder = new TextEncoder();
    const data = encoder.encode(fingerprintData);

    // Compute SHA-256 hash
    const hashBuffer = await crypto.subtle.digest("SHA-256", data);
    const hashArray = Array.from(new Uint8Array(hashBuffer));

    // Convert to hex string
    return hashArray.map((b) => b.toString(16).padStart(2, "0")).join("");
  } catch (error) {
    console.error("Error generating fingerprint:", error);
    return null; // Fallback if hashing fails
  }
}

// Modify Honeybadger before reporting
honeybadger.beforeNotify(async (notice) => {
  if (notice.backtrace && notice.backtrace.length > 0) {
    const firstFrame = notice.backtrace[0];
    const fingerprint = await generateFingerprint(firstFrame);

    if (fingerprint) {
      notice.fingerprint = fingerprint;
    }
  }
});

export default honeybadger;

Sorry, I meant to use notice.backtrace instead of notice.stack. I have updated the gist.
