Embed a Changelog

Prerequisites

• Nordva Launch account with at least one published changelog entry
• Any frontend framework (or plain HTML)

The public feed (GET /public/changelog/<your-project-slug>) needs no API key and allows any origin, so your visitors’ browsers can call it directly. Entries carry body_markdown; render it with the Markdown library you already use.

Option A: Script-tag widget (zero code)

Drop this into any HTML page:

<script src="https://cdn.nordva.dev/v1/changelog.js"
  data-key="nv_pub_live_YOUR_KEY"
  data-theme="auto"
  data-limit="5"
  data-show-badge="true">
</script>
<nordva-changelog></nordva-changelog>

The widget renders inside a Shadow DOM — no style conflicts with your page. The data-show-badge="true" attribute shows a “New” badge when entries have been published since the user last visited.

Attributes:

Attribute	Default	Description
data-key	required	Your publishable key (nv_pub_...)
data-theme	auto	light, dark, or auto (follows system preference)
data-limit	5	Number of entries to show (max 50)
data-show-badge	false	Show “New” badge when there are unseen entries

Option B: Fetch in Astro (server-side, no auth)

src/pages/changelog.astro

---
import { marked } from 'marked';
const res = await fetch('https://api.nordva.dev/public/changelog/your-project-slug');
const { data: entries } = await res.json();
---

<main>
  {entries.map(entry => (
    <article>
      <time>{new Date(entry.published_at).toLocaleDateString()}</time>
      <h2><a href={entry.public_url}>{entry.title}</a></h2>
      <small>{entry.category}{entry.version ? ` · ${entry.version}` : ''}</small>
      <div set:html={marked.parse(entry.body_markdown)} />
    </article>
  ))}
</main>

No API key needed. This renders at build time in Astro’s static mode.

Option C: Fetch in React (client-side, no auth)

import { useEffect, useState } from 'react';
import { marked } from 'marked';

interface ChangelogEntry {
  id: string;
  title: string;
  body_markdown: string;
  category: 'feature' | 'fix' | 'improvement' | 'security' | 'breaking';
  version: string | null;
  published_at: string;
  public_url: string;
}

export function Changelog() {
  const [entries, setEntries] = useState<ChangelogEntry[]>([]);

  useEffect(() => {
    fetch('https://api.nordva.dev/public/changelog/your-project-slug')
      .then(r => r.json())
      .then(({ data }) => setEntries(data.slice(0, 10)));
  }, []);

  return (
    <ul>
      {entries.map(entry => (
        <li key={entry.id}>
          <time>{new Date(entry.published_at).toLocaleDateString()}</time>
          <h3><a href={entry.public_url}>{entry.title}</a></h3>
          <div dangerouslySetInnerHTML={{ __html: marked.parse(entry.body_markdown) }} />
        </li>
      ))}
    </ul>
  );
}

Publish an entry

From the Nordva Launch dashboard → Changelog, or via the API:

curl -X POST https://api.nordva.dev/v1/changelog/entries \
  -H "Authorization: Bearer nv_live_YOUR_SECRET_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "Dark mode is here",
    "body_markdown": "## Dark mode\n\nYou can now toggle dark mode from settings.",
    "category": "feature",
    "notify_subscribers": true
  }'

Let users subscribe

Add an email subscription form using a publishable key:

const res = await fetch('https://api.nordva.dev/v1/changelog/subscribers', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer nv_pub_live_YOUR_KEY',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({ email: 'user@example.com' }),
});
// 201: subscribed, 409: already subscribed

Subscribers receive an email when you publish with notify_subscribers: true.
