New Features

Limited BoxLang Support

CBWIRE 4.1 introduces BoxLang support, allowing you to build components and templates using BoxLang's powerful, modular, and modern feature set. This opens up a whole new world of possibilities for CBWIRE development with BoxLang's enhanced syntax and capabilities.

Requirements:

bx-compat-cfml BoxLang module
bx-esapi BoxLang module

// wires/UserDashboard.bx
class extends="cbwire.models.Component" {
    data = {
        "users": [],
        "searchTerm": "",
        "selectedRole": "all"
    };
    
    function onMount() {
        data.users = getUserService().getAllUsers();
    }
    
    function filterUsers() {
        var filteredUsers = data.users
            .filter(function(user) {
                return data.selectedRole == "all" || user.role == data.selectedRole;
            })
            .filter(function(user) {
                return !data.searchTerm.len() || 
                       user.name.findNoCase(data.searchTerm) || 
                       user.email.findNoCase(data.searchTerm);
            });
        
        return filteredUsers;
    }
}

// wires/UserDashboard.cfc

    data = {
        "users" = [],
        "searchTerm" = "",
        "selectedRole" = "all"
    };
    
    function onMount() {
        data.users = getUserService().getAllUsers();
    }
    
    function filterUsers() {
        var filteredUsers = data.users
            .filter(function(user) {
                return data.selectedRole == "all" || user.role == data.selectedRole;
            })
            .filter(function(user) {
                return !len(data.searchTerm) || 
                       findNoCase(data.searchTerm, user.name) || 
                       findNoCase(data.searchTerm, user.email);
            });
        
        return filteredUsers;
    }
}

BoxLang brings modern language features like enhanced member functions, improved syntax, and better type handling to your CBWIRE components.

Assets Management

CBWIRE 4.1 introduces <cbwire:script> and <cbwire:assets> functionality for better control over component-specific assets. These assets are automatically tracked throughout the request and appended to the <head> tag during page load.

<!-- wires/dashboard.bxm -->
<bx:output>
<cbwire:script>
    console.log('Dashboard component loaded');
    // Component-specific JavaScript
</cbwire:script>

<cbwire:assets>
    <link rel="stylesheet" href="/css/dashboard.css">
    <script src="/js/chart-library.js"></script>
</cbwire:assets>

<div>
    <h1>Dashboard</h1>
    <!-- Component content -->
</div>
</bx:output>

<!-- wires/dashboard.cfm -->
<cfoutput>
<cbwire:script>
    console.log('Dashboard component loaded');
    // Component-specific JavaScript
</cbwire:script>

<cbwire:assets>
    <link rel="stylesheet" href="/css/dashboard.css">
    <script src="/js/chart-library.js"></script>
</cbwire:assets>

<div>
    <h1>Dashboard</h1>
    <!-- Component content -->
</div>
</cfoutput>

Locked Data Properties

Protect sensitive data properties from client-side modifications by defining a locked variable in your component. This prevents certain properties from being updated via wire:model or other client interactions.

// wires/UserProfile.bx
class extends="cbwire.models.Component" {
    // Lock single property
    locked = "userId";
    
    // Or lock multiple properties
    locked = ["userId", "role", "permissions"];
    
    data = {
        "userId": 123,
        "name": "John Doe",
        "email": "[email protected]",
        "role": "admin",
        "permissions": ["read", "write"]
    };
}

// wires/UserProfile.cfc
component extends="cbwire.models.Component" {
    // Lock single property
    locked = "userId";
    
    // Or lock multiple properties
    locked = ["userId", "role", "permissions"];
    
    data = {
        "userId" = 123,
        "name" = "John Doe",
        "email" = "[email protected]",
        "role" = "admin",
        "permissions" = ["read", "write"]
    };
}

<!-- Template can bind to name/email but userId/role are protected -->
<input wire:model="name" placeholder="Name">
<input wire:model="email" placeholder="Email">
<!-- These would throw "Locked properties cannot be updated" if attempted -->

Module Root URL Configuration

Configure custom module root URLs for better control over CBWIRE routing in complex applications.

// config/ColdBox.bx
moduleSettings = {
    "cbwire": {
        "moduleRootURL": "/custom/cbwire/path"
    }
};

File Upload Enhancement

New getTemporaryStoragePath() method in FileUpload components provides access to temporary file storage locations.

// wires/FileManager.bx
class extends="cbwire.models.Component" {
    function processUpload() {
        if (data.upload) {
            var tempPath = data.upload.getTemporaryStoragePath();
            // Process file at temporary location
        }
    }
}

// wires/FileManager.cfc
component extends="cbwire.models.Component" {
    function processUpload() {
        if (structKeyExists(data, "upload")) {
            var tempPath = data.upload.getTemporaryStoragePath();
            // Process file at temporary location
        }
    }
}

Progress Bar Customization

Enhanced progress bar configuration with proper color setting and disable functionality.

// config/ColdBox.bx
moduleSettings = {
    "cbwire": {
        "showProgressBar": false,           // Disable completely
        "progressBarColor": "##00ff00"      // Custom color (fixed)
    }
};

// config/ColdBox.cfc
moduleSettings = {
    "cbwire" = {
        "showProgressBar" = false,          // Disable completely
        "progressBarColor" = "##00ff00"     // Custom color (fixed)
    }
};

String Trimming

Automatically trim whitespace from string values in form inputs.

// Global setting
moduleSettings = {
    "cbwire": {
        "trimStringValues": true
    }
};

// Or per component
class extends="cbwire.models.Component" {
    function shouldTrimStringValues() {
        return true;
    }
}

// Global setting
moduleSettings = {
    "cbwire" = {
        "trimStringValues" = true
    }
};

// Or per component
component extends="cbwire.models.Component" {
    function shouldTrimStringValues() {
        return true;
    }
}

External Module Support

Load CBWIRE components from external module locations for better code organization.

Update Endpoint Configuration

Customize the CBWIRE update endpoint for advanced routing scenarios.

// config/ColdBox.bx
moduleSettings = {
    "cbwire": {
        "updateEndpoint": "/custom/cbwire/update"
    }
};

Enhancements

Asset Rendering Optimization

Assets are now tracked throughout the request and only rendered once
Component-specific assets are automatically injected into the <head> tag
Prevents duplicate asset loading for better performance

Performance Improvements

CBWIRE rendering speed improvements
Enhanced child/nested component tracking
Optimized asset management and injection

Bug Fixes

Component Lifecycle

Fixed onRender() method: Restored missing onRender() method from previous versions
Fixed onUpdate() behavior: Resolved issue where onUpdate() was called when no updates occurred

Component Management

Child/nested component tracking: Improved tracking of child components in Livewire
Component isolation: Better handling of component isolation and lazy loading

Asset Management

Duplicate asset prevention: Assets that have already been rendered are not returned again
Asset injection: Component assets are properly tracked and injected into page head

External Module Support

Module loading: Fixed issues loading wires from external module locations
Path resolution: Improved component path resolution for complex module structures
