AdminLTE is a static HTML/CSS/JS template — there’s nothing exotic about
deploying it. But there are a handful of choices that meaningfully change page
weight, time-to-interactive, and CDN reliability. This page documents the ones
worth getting right.
</p>
<h5 id="what-to-deploy">What to deploy</h5>
<p>
The deployable artefact is everything under <code>dist/</code> plus your own
HTML / server-rendered templates:
</p>
<pre
class="astro-code dark-plus"
style="background-color: #1e1e1e; color: #d4d4d4; overflow-x: auto"
tabindex="0"
data-language="text"
><code><span class="line"><span>dist/</span></span>
<span class="line"><span>├── css/ ← stylesheets (LTR + RTL, dev + minified)</span></span>
<span class="line"><span>│ ├── adminlte.css</span></span>
<span class="line"><span>│ ├── adminlte.min.css</span></span>
<span class="line"><span>│ ├── adminlte.rtl.css</span></span>
<span class="line"><span>│ └── adminlte.rtl.min.css</span></span>
<span class="line"><span>├── js/ ← JavaScript bundle (dev + minified)</span></span>
<span class="line"><span>│ ├── adminlte.js</span></span>
<span class="line"><span>│ └── adminlte.min.js</span></span>
<span class="line"><span>└── assets/ ← demo images / fonts (replace with your own)</span></span></code></pre>
<p>
You don’t ship <code>src/</code>, <code>node_modules/</code>, or the demo HTML
if you’re embedding AdminLTE into your own app.
</p>
<h5 id="always-use-the-min-variants-in-production">
Always use the <code>.min</code> variants in production
</h5>
<p>
The minified builds are the same code with whitespace stripped and identifiers
shortened. For <code>adminlte.css</code> the saving is roughly 15-20%; for
<code>adminlte.js</code> it’s bigger (about 30% after gzip). The non-minified
files are useful in development for readable source-map debugging — never
serve them to users.
</p>

Make sure your web server / CDN gzips (or brotlis) responses for the relevant
content types:
</p>

<p>
Cloudflare, Vercel, Netlify, and most managed hosting do this automatically.
Verify with
<code>curl -I -H "Accept-Encoding: gzip" your-page-url</code> and
look for <code>content-encoding: gzip</code> in the response.
</p>
<h5 id="cache-headers">Cache headers</h5>
<p>
The dist artefacts have content hashes in their filenames
<em>only if you wire it up via your bundler</em> — AdminLTE itself ships fixed
filenames. Two reasonable strategies:
</p>
<ol>
<li>
<p>
<strong>Short cache + version query string</strong> (simple, works without
a build pipeline):
</p>
<pre

Let your bundler emit <code>adminlte.[hash].min.css</code> and reference
that hash in your HTML. Set

This is what Vite/Webpack/Rollup do by default if you import AdminLTE
through them.

If you load AdminLTE from a public CDN (jsDelivr, unpkg), include a
Subresource Integrity (SRI) hash so a compromised CDN can’t serve malicious
JavaScript silently:

<h5 id="defer-or-async">Defer or async?</h5>
<p>
The AdminLTE bundle waits for <code>DOMContentLoaded</code> before wiring its
data API, so <code>defer</code> is safe and recommended:
</p>
<pre
class="astro-code dark-plus"
style="background-color: #1e1e1e; color: #d4d4d4; overflow-x: auto"
tabindex="0"
data-language="html"

<p>
Don’t use <code>async</code> — the script could execute before its
dependencies (Bootstrap, Popper) have parsed, and listeners would attach to
elements that don’t exist yet.
</p>
<h5 id="critical-css">Critical CSS</h5>
<p>
For sub-1-second first paint, inline the styles that the above-the-fold layout
uses (header + brand + first visible content) and load the rest of
<code>adminlte.min.css</code> asynchronously:

Extract critical CSS with a tool like
<a href="https://github.com/GoogleChromeLabs/critters">Critters</a> or
<a href="https://github.com/pocketjoso/penthouse">Penthouse</a> as part of
your build. For dashboards behind a login (where first-load speed matters less
than for marketing pages), this is usually overkill.

Only preload what’s used on every page. Preloading per-route assets in a
shared layout wastes bandwidth.
</p>
<h5 id="lazy-loading-sub-pages">Lazy-loading sub-pages</h5>
<p>
If your dashboard has many routes and the JS is server-rendered HTML per
route, prefer per-route CSS imports rather than one mega-stylesheet.
AdminLTE’s core CSS is small (~44KB gzipped) but page-specific styles (charts,
calendars, tables) can add up — only load them where they’re used.
