Module Dependencies

// Dependency tree
onigiri-core.js (required, no dependencies)
├── onigiri-events.js (depends on: core)
│   └── onigiri-components.js (depends on: core, events)
│       └── onigiri-humhub.js (depends on: core, events, components)
├── onigiri-security.js (depends on: core)

Checking Loaded Modules

// Check which modules are loaded
console.log(Onigiri.modules);
// { core: true, events: true, components: true, ... }

// Check specific module
if (Onigiri.modules.security) {
    // Security module is loaded
    Onigiri.security.init();
}

if (Onigiri.modules.pjax) {
    // PJAX module is loaded
    Onigiri.pjax.init();
}

Conditional Loading

Load Modules Based on Features

<!-- Core always loaded -->
<script src="onigiri-core.js"></script>

<?php if ($needsComponents): ?>
    <script src="onigiri-events.js"></script>
    <script src="onigiri-components.js"></script>
<?php endif; ?>

<?php if ($needsAjax): ?>
    <script src="onigiri-security.js"></script>
    <script src="onigiri-ajax.js"></script>
<?php endif; ?>

<?php if ($needsValidation): ?>
    <script src="onigiri-validation.js"></script>
<?php endif; ?>

Dynamic Module Loading

// Load module dynamically
async function loadModule(moduleName) {
    return new Promise((resolve, reject) => {
        const script = document.createElement('script');
        script.src = \`onigiri.\${moduleName}.js\`;
        script.onload = resolve;
        script.onerror = reject;
        document.head.appendChild(script);
    });
}

// Usage
async function enableValidation() {
    if (!Onigiri.modules.validation) {
        await loadModule('validation');
        console.log('🍙 Validation module loaded!');
    }
    
    // Now use validation
    const result = O('#form').validate(rules);
}

Build Your Own Bundle

Custom Build Script

// build-custom.js
const fs = require('fs');

const modules = [
    'onigiri-core.js',
    'onigiri-events.js',
    'onigiri-components.js',
    'onigiri-security.js',
    'onigiri-ajax.js'
];

let combined = '';

modules.forEach(module => {
    combined += fs.readFileSync(module, 'utf8');
    combined += '\n\n';
});

fs.writeFileSync('onigiri.custom.js', combined);
console.log('🍙 Custom bundle created!');

Concatenate Modules

#!/bin/bash
# build.sh

# Create custom bundle
cat onigiri-core.js \
    onigiri-events.js \
    onigiri-components.js \
    onigiri-security.js \
    onigiri-ajax.js \
    onigiri-storage.js \
    > onigiri.bundle.js

echo "🍙 Bundle created: onigiri.bundle.js"

Module Best Practices

• Always load core.js first
• Respect module dependencies
• Only load modules you actually use
• Check Onigiri.modules before using features
• Consider creating custom bundles for production
• Test with only required modules loaded
• Document which modules your code needs
• Use conditional loading for optional features

Future Modules

Modules planned for future releases:

• onigiri.router.js - Client-side routing
• onigiri.i18n.js - Internationalization
• onigiri.websocket.js - WebSocket support
• onigiri.charts.js - Data visualization
• onigiri.drag.js - Drag and drop

Creating Custom Modules

// onigiri.custom.js - Custom module template
(function(Onigiri) {
    'use strict';

    if (!Onigiri) {
        throw new Error('OnigiriJS core not found');
    }

    // Your custom functionality
    Onigiri.customFeature = {
        init: function() {
            console.log('🍙 Custom feature initialized');
        },
        
        doSomething: function() {
            // Your code here
        }
    };

    // Register module
    Onigiri.modules.custom = true;

})(typeof Onigiri !== 'undefined' ? Onigiri : null);
