@athon-labs/help-widget-svelte

Svelte 5 help widget for SvelteKit or plain Svelte. Pass the logged-in user and a URL on your backend. The widget POSTs title, message, reporter fields, and screenshots there. Keep the Athon sk_live_* key on the server.

Install

npm install @athon-labs/help-widget-svelte

Usage

<script lang="ts">
  import { HelpWidget } from '@athon-labs/help-widget-svelte';

  let { user }: { user: { id: string; email: string; name: string } } = $props();
</script>

<HelpWidget
  endpoint="/api/support/report"
  {user}
  color="#3d8f78"

Screenshots

Users can capture the entire screen, the current window/tab, or attach photos. The browser will prompt for screen-share permission. Dismissing the picker is ignored. Images must be PNG, JPEG, WebP, or GIF (max 5).

Backend proxy

The widget does not talk to Athon directly. Your server receives the multipart POST, adds appId (or projectId) and Authorization: Bearer sk_live_…, then forwards to Athon ingest.

ATHON_LIVE_KEY=sk_live_…
ATHON_APP_ID=app_…
ATHON_INGEST_URL=https://YOUR_ATHON_HOST/api/v1/ingest/issues

SvelteKit

src/routes/api/support/report/+server.ts:

import { env } from '$env/dynamic/private';
import type { RequestHandler } from './$types';

export const POST: RequestHandler = async ({ request }) => {
  const form = await request.formData();
  form.set('appId', env.ATHON_APP_ID);

  const upstream = await fetch(env.ATHON_INGEST_URL, {
    method: 'POST',
    headers: { Authorization: `Bearer ${env.ATHON_LIVE_KEY}` },
    body: form,
  });

  return new Response(await upstream.text(), {
    status: upstream.status,
    headers: { 'content-type': upstream.headers.get('content-type') ?? 'application/json' },
  });
};

Point <HelpWidget endpoint="/api/support/report" /> at that route.

Next.js

app/api/support/report/route.ts:

export async function POST(request: Request) {
  const form = await request.formData();
  form.set('appId', process.env.ATHON_APP_ID ?? '');

  const upstream = await fetch(process.env.ATHON_INGEST_URL ?? '', {
    method: 'POST',
    headers: { Authorization: `Bearer ${process.env.ATHON_LIVE_KEY}` },
    body: form,
  });

  return new Response(await upstream.text(), {
    status: upstream.status,
    headers: { 'content-type': upstream.headers.get('content-type') ?? 'application/json' },
  });
}

Node.js

Node 18+. Do not run a JSON body parser on this route.

import { createServer } from 'node:http';

const server = createServer(async (req, res) => {
  if (req.method !== 'POST' || req.url !== '/api/support/report') {
    res.writeHead(404);
    res.end('Not found');
    return;
  }

  const incoming = new Request('http://local/api/support/report', {
    method: 'POST',
    headers: req.headers,
    body: req,
    duplex: 'half',
  });

  const form = await incoming.formData();
  form.set('appId', process.env.ATHON_APP_ID ?? '');

  const upstream = await fetch(process.env.ATHON_INGEST_URL ?? '', {
    method: 'POST',
    headers: { Authorization: `Bearer ${process.env.ATHON_LIVE_KEY}` },
    body: form,
  });

  res.writeHead(upstream.status, {
    'content-type': upstream.headers.get('content-type') ?? 'application/json',
  });
  res.end(await upstream.text());
});

server.listen(3000);
