What's New
In this major Wappler update we have completely redesigned the Wappler Options Panel to make it easier to find and understand the various options available in Wappler.
The options can also be configured per project now, so you can have different settings for each project you are working on.
Futhermore we are excited to announce the release of App Connect 2.2.0, our biggest performance and stability update yet! This release brings dramatic speed improvements (up to 64% faster!), enhanced reliability through comprehensive testing, and several new features that make building reactive applications even better.
New Wappler Options Panel
- The options panel is completely redesigned and reorganized to show the Wappler options well categorized and explained.
- Now you can have options also specific for your project, so you can have different settings per project.
- Api keys and sensitive data are now stored securely encrypted now.
App Connect 2.2.0
Performance Improvements
Blazing Fast Reactive Updates
We've completely optimized the reactive engine and component rendering, delivering massive performance gains across the board:
- Reactive populate operations: Up to 64% faster

- Large dataset handling: 47% faster for fast repeat operations
- Nested component updates: 43% faster reactive nested toggles
- Cascading updates: 35% faster reactive cascades
- Overall performance: 19% faster aggregate across all operations
Real-World Impact
What does this mean for your applications?
Smoother animations and transitions
Instant response to user interactions
Faster page loads with large datasets
Better performance on lower-end devices
More responsive forms and data tables
Technical Optimizations
- Smart expression caching - Compiled expressions are now cached per scope, eliminating thousands of redundant evaluations
- Optimized signal propagation - Reactive updates now use breadth-first queuing with intelligent batching
- Faster repeat rendering - Non-keyed repeats reuse constructors and fragments, significantly reducing DOM operations
- Streamlined parser - Lexer whitespace trimming and pooled argument buffers reduce memory allocations
- Enhanced equality checks - Optimized comparisons for arrays, typed arrays, Maps, and Sets
Rock-Solid Stability
Comprehensive Test Coverage
We've built an extensive testing framework with over 1,800 automated tests to ensure App Connect works flawlessly:
1,842 unit tests covering every formatter, component, and utility
19 browser integration tests validating real-world scenarios
99.9% test pass rate - nearly perfect reliability
90% code coverage - thoroughly tested codebase
What This Means for You
Fewer bugs - Issues caught before they reach production
Faster fixes - Problems identified and resolved quickly
Continuous improvement - Every commit is automatically tested
Production-ready - Enterprise-grade quality assurance
New Features & Enhancements
Enhanced Data Handling
Better Clone & Equality Operations
- Typed array support - Proper handling of
Int8Array,Uint8Array,Float32Array, etc. - DataView cloning - Correct slicing semantics preserved
- Map & Set comparison - Respects insertion ordering for reliable equality checks
- ImageData support - Properly duplicates underlying buffers
- NaN handling - Treats
NaNvalues as equal in comparisons (as expected) - Prototype pollution prevention - Safer object cloning that skips
__proto__assignments
Improved Array Operations
- Case-insensitive membership -
where()withinArray/notInArraynow works correctly with case-insensitive matching - Better null handling - Array formatters gracefully handle edge cases
Security Enhancements
- XSS Protection - The
stripTags()formatter now properly removes<script>and<style>content, preventing potential security vulnerabilities - Safer data operations - Enhanced input validation across formatters
String Formatters
- Improved
trunc()- Better ellipsis handling with standard "..." characters - Smarter
slugify()- No more trailing dashes in generated slugs - Robust
repeat()- Better error handling for invalid inputs
Date Formatting
- Uppercase token support -
YYYYandDDtokens now work correctly (previously only lowercase worked)
Number Formatting
- Better defaults -
formatNumber()now defaults to comma thousand separators for improved readability
JSON Support
- Global formatter -
json()formatter now available for easy JSON stringification
API Improvements
- Dynamic adapter registration -
dmx.Adapter()now auto-creates type objects when registering new adapter types - Better type handling - More reliable component and adapter initialization
Framework Utilities
- Fixed throttle function - Event throttling now works correctly in all scenarios
- Improved flow expressions - Flow actions can now safely differentiate literal strings from dynamic expressions
Stability Fixes
We've identified and resolved several edge cases and issues to make App Connect more reliable:
Core Improvements
- Fixed event throttling for delayed callbacks
- Resolved adapter initialization for new types
- Corrected clone operations for native ArrayBuffer instances
String Formatters
- Better handling of null and undefined values
- Improved edge case handling in
trunc(),slugify(), andrepeat() - Enhanced security with proper
<script>tag content removal instripTags()
Array Operations
- Fixed case-insensitive membership checks in
where()operations - More consistent behavior with empty arrays and null values
Component Rendering
- Optimized repeat component updates with better memory management
- Enhanced reactive propagation with fewer redundant computations
