Wiki — Docs Page (dev-docs layout + code)
A polished developer-docs page in the Stripe and Tailwind docs vein, built as a self-contained three-column shell for a fictional Aurora DB knowledge base. A collapsible doc-tree sidebar sits left, the readable serif article column runs down the center with breadcrumbs, callouts, tables, and syntax-highlighted-looking code blocks, and a scrollspy table of contents tracks the right rail. Code blocks carry a copy button and a curl/JavaScript/Python tab switcher, and a header light or dark toggle persists across reloads.

Run reads against an <strong>Aurora DB</strong> cluster from the official client. This
page covers single-statement queries, parameter binding, typed result rows, and the
cursor API used by <code>Project Nimbus</code> for large exports.

<h2 id="overview">Overview</h2>
<p>
The <code>query()</code> method sends a statement to the primary node and returns a typed
result set. Statements are parsed once and cached per connection, so repeating a query
with different parameters reuses the prepared plan. For workloads that read more than a
few thousand rows, prefer the <a href="#cursors">cursor API</a> so results stream instead
of buffering in memory.

Connect, then call <code>query()</code> with a parameterized statement. Positional
parameters (<code>$1</code>, <code>$2</code>) are bound server-side, so user input is
never concatenated into SQL. The example below fetches active members of the

<h2 id="typed-rows">Typed rows</h2>
<p>
Each row is a plain object keyed by column name. Pass a type parameter to get full
editor autocomplete on the returned shape. Columns map to their nearest host type —
<code>timestamptz</code> becomes a <code>Date</code>, <code>jsonb</code> is parsed, and
<code>numeric</code> stays a string to preserve precision.
</p>
<table class="doc-table">
<thead>
<tr><th>Aurora type</th><th>JS type</th><th>Notes</th></tr>
</thead>
<tbody>
<tr><td><code>int8</code></td><td><code>number</code> / <code>bigint</code></td><td>bigint past 2⁵³</td></tr>
<tr><td><code>numeric</code></td><td><code>string</code></td><td>lossless decimal</td></tr>
<tr><td><code>timestamptz</code></td><td><code>Date</code></td><td>always UTC</td></tr>
<tr><td><code>jsonb</code></td><td><code>object</code></td><td>parsed eagerly</td></tr>
<tr><td><code>uuid</code></td><td><code>string</code></td><td>lowercased</td></tr>
</tbody>
</table>
<h2 id="cursors">Streaming with cursors</h2>
<p>
For large result sets, open a cursor and iterate. Rows arrive in batches of
<code>fetchSize</code> (default 500) and the connection stays pinned until the cursor is
drained or closed. This keeps memory flat regardless of how many rows match.

Failed queries throw an <code>AuroraError</code> with a stable <code>code</code> you can

logical errors surface to your code.

</html>Docs Page (dev-docs layout + code)
A full developer-documentation page modeled on the Stripe and Tailwind docs feel and rendered for a fictional Aurora DB SDK reference. The shell is a three-column grid: a collapsible doc-tree navigation on the left with expandable branches, a centered article column capped near 760px that mixes an Inter UI chrome with a Source Serif 4 reading body, and a right-rail table of contents. The article carries breadcrumbs, an eyebrow and lede, Note / Tip / Warning callouts, a typed-columns reference table, a pull quote, and prev/next page links.
The code blocks are the centerpiece: each one is wrapped in a tabbed panel that swaps between cURL, JavaScript, and Python samples, with faux syntax-token coloring in JetBrains Mono and a copy button that writes the active snippet to the clipboard and confirms with a toast. A header theme toggle flips the whole page between a clean white and a dark palette and remembers the choice in localStorage, falling back to the OS preference on first load.
Interactions are pure vanilla JS: language tabs, clipboard copy with a graceful execCommand fallback, doc-tree collapse, an IntersectionObserver scrollspy that highlights the current TOC entry, a / shortcut that focuses search, page-helpfulness voting, and a mobile drawer with a scrim that collapses the sidebar below 820px down to 360px.
Illustrative UI only — fictional articles, products, and data.
