Comparison with Other Template Engines
This page compares CandidTemplate with Blade (Laravel) and Twig (Symfony) —
the two most widely used PHP templating engines. The goal is to help you
understand the trade-offs and choose the right tool for your use case.

1. Fundamental Approach
| Aspect |
CandidTemplate |
Blade (Laravel) |
Twig (Symfony) |
| Core approach |
DOM manipulation |
String compilation |
String compilation |
| Template syntax |
Pure HTML + PHP API |
Custom directives in HTML |
Custom syntax in HTML |
| Template files |
Valid HTML — opens in any browser |
.blade.php — not valid HTML |
.twig — not valid HTML |
| Compilation |
None — DOM parsed at runtime |
Compiled to PHP, cached |
Compiled to PHP, cached |
| Designer friendly |
✅ Pure HTML, no special syntax |
⚠️ Directives break preview |
⚠️ Tags break preview |
| Framework coupling |
✅ Standalone, no framework needed |
❌ Tied to Laravel |
⚠️ Standalone possible but complex |
| Vue/React compatibility |
✅ Safe — event syntax protected |
⚠️ Conflicts with {{ }} |
⚠️ Conflicts with {{ }} |
| HTML validity guaranteed |
✅ DOM enforced |
❌ String output unchecked |
❌ String output unchecked |
| Learning curve |
Low — HTML + PHP you already know |
Medium — new directive syntax |
Medium — new template language |
| Nested layouts |
✅ Native via slots |
✅ Via @extends/@yield |
✅ Via extends/block |
| Component system |
Slots + Includes |
Blade Components |
Macros + Includes |
| Logic separation |
✅ Data files |
✅ Controllers + View Composers |
✅ Controllers + Extensions |

2. Syntax Comparison — Content Binding
|
Template (HTML) |
Binding (PHP) |
| CandidTemplate |
<h1 id="pageTitle"></h1>
<p class="subtitle"></p>
|
$tpl->pick('#pageTitle')
->content('Welcome to Sony News');
$tpl->pick('.subtitle')
->content('Latest breaking news');
|
| Blade |
<h1>{{ $pageTitle }}</h1>
<p>{{ $subtitle }}</p>
|
return view('home', [
'pageTitle' => 'Welcome to Sony News',
'subtitle' => 'Latest breaking news',
]);
|
| Twig |
<h1>{{ pageTitle }}</h1>
<p>{{ subtitle }}</p>
|
return $twig->render('home.twig', [
'pageTitle' => 'Welcome to Sony News',
'subtitle' => 'Latest breaking news',
]);
|
---
3. Loop Comparison
|
Template (HTML) |
PHP |
| CandidTemplate |
<div id="newsCard">
<a id="cardTitle" href="#"></a>
<span id="cardDate"></span>
</div>
|
foreach ($articles as $article) {
$item = $tpl->addLoopItem('newsCard');
$item->pick('cardTitle')
->content($article->title)
->href($article->url);
$item->pick('cardDate')
->content($article->date);
}
|
| Blade |
@foreach ($articles as $article)
<div class="news-card">
<a href="{{ $article->url }}">{{ $article->title }}</a>
<span>{{ $article->date }}</span>
</div>
@endforeach
|
| Twig |
{% for article in articles %}
<div class="news-card">
<a href="{{ article.url }}">{{ article.title }}</a>
<span>{{ article.date }}</span>
</div>
{% endfor %}
|

4. Layout / Slot Comparison
|
Layout Definition |
Slot Registration |
| CandidTemplate |
<div data-slot="content"></div>
<div data-slot="sidebar"></div>
|
$view->slot('content', 'home');
$view->slot('sidebar', 'sidebar');
|
| Blade |
@yield('content')
@yield('sidebar')
|
@extends('layout')
@section('content') ... @endsection
@section('sidebar') ... @endsection
|
| Twig |
{% block content %}{% endblock %}
{% block sidebar %}{% endblock %}
|
{% extends 'layout.twig' %}
{% block content %} ... {% endblock %}
{% block sidebar %} ... {% endblock %}
|
---
5. Conditional Rendering Comparison
| CandidTemplate |
Blade |
Twig |
// Element level
$tpl->pick('.admin-panel')
->showIf($user->isAdmin());
// Slot level — no file I/O
$view->slotIf(
$user->isAdmin(),
'admin',
'admin-panel'
);
|
@if ($user->isAdmin())
@include('admin-panel')
@endif
|
{% if user.isAdmin %}
{% include 'admin-panel.twig' %}
{% endif %}
|

6. Vue / Frontend Framework Compatibility
| Scenario |
CandidTemplate |
Blade |
Twig |
{{ variable }} conflict |
✅ No conflict — no {{ }} syntax |
❌ Conflicts — use @{{ }} workaround |
❌ Conflicts — use {% verbatim %} |
@click events |
✅ Protected and restored transparently |
⚠️ Blade treats @ as directive prefix |
✅ No conflict |
| SSR + Vue hydration |
✅ Clean HTML output, safe to hydrate |
⚠️ Possible conflicts |
⚠️ Possible conflicts |
| Mixed PHP render + Vue reactivity |
✅ PHP renders structure, Vue handles updates |
⚠️ Requires careful separation |
⚠️ Requires careful separation |

7. HTML Integrity
| Concern |
CandidTemplate |
Blade |
Twig |
| Malformed HTML detection |
✅ DOMDocument catches errors |
❌ Silent string output |
❌ Silent string output |
| Script/style content preserved |
✅ Token protection system |
✅ Not parsed |
✅ Not parsed |
| Attribute injection prevention |
✅ DOM setAttribute enforced |
⚠️ Manual escaping required |
✅ Auto-escaped by default |
| XSS protection |
⚠️ Planned — safeContent() |
✅ {{ }} auto-escapes |
✅ Auto-escaped by default |
Note: CandidTemplate does not yet auto-escape output.
Always sanitize user-supplied data before passing to content().
Auto-escaping via safeContent() is planned.

8. Performance Comparison
| Aspect |
CandidTemplate |
Blade |
Twig |
| Template compilation |
None |
Compiled + cached to PHP |
Compiled + cached to PHP |
| Runtime cost |
DOMDocument parse per template |
Low — cached PHP executed |
Low — cached PHP executed |
| Loop cost |
DOM clone per item |
String append per item |
String append per item |
| Output caching |
⚠️ Planned |
✅ Via Laravel cache |
✅ Via Twig cache |
| Conditional slot skip |
✅ slotIf() — no file I/O |
⚠️ Template still loaded |

9. When to Use Each

Recommended |
Reason |
| Laravel application |
Blade |
Native integration, ecosystem support |
| Symfony application |
Twig |
Native integration, ecosystem support |
| Standalone PHP with Vue/React |
CandidTemplate |
No syntax conflicts, clean SSR output |
| Designer-maintained HTML |
CandidTemplate |
Pure HTML — no template syntax to learn |
| Structured component-driven UI |
CandidTemplate |
Slots + picks give clean component model |
| Rapid prototyping with Laravel |
Blade |
Tight controller integration |
| Multi-developer team with designers |
CandidTemplate |
Designers work in plain HTML independently |
| API-driven app, minimal server rendering |
Twig or Blade |
Lighter weight for minimal HTML output |

10. Strengths of CandidTemplate
- ✅ Pure HTML templates —
no custom syntax, valid in any browser or editor
- ✅ DOM-enforced structure —
malformed HTML caught at parse time
- ✅ Vue/React safe —
no
{{ }} conflicts,
@event attributes protected transparently
- ✅ Clean slot wrapper removal —
no leftover placeholder divs in output
- ✅ Deferred assignments —
all
pick() calls queued, applied at render
- ✅ Framework-agnostic —
standalone, no framework dependency
- ✅ Data file separation —
view binding logic cleanly separated from controllers
- ✅ slotIf() —
skip file I/O entirely for conditional sections
- ✅ Designer-developer workflow —
designers edit HTML, developers bind data independently

11. Current Limitations
| Limitation |
Detail |
Status |
| No auto-escaping |
User input must be manually sanitized |
⚠️ Planned — safeContent() |
| No output caching |
DOM parsed on every request |
⚠️ Planned |
| Limited CSS selectors |
No combinators or pseudo-selectors |
By design — extendable |
| DOMDocument overhead |
Heavier than string parsing for simple cases |
Acceptable for structured UIs |
| No framework integration |
No native Laravel/Symfony bridge |
By design — standalone |
| Large loop performance |
DOM clone per item —
avoid 100+ item loops |
Paginate server-side |

Bottom line: Choose Blade if you are in the Laravel ecosystem.
Choose Twig if you are in the Symfony ecosystem.
Choose CandidTemplate if you want pure HTML templates,
clean Vue/React compatibility, and a structured
component-driven UI without framework lock-in.
