Exploring ultimate user experience and best engineering practices
This article examines utoo, a Rust‑rewritten npm package manager that achieves near‑instant installs and dramatically smaller caches while remaining a drop‑in replacement for npm, detailing its architecture, benchmark comparisons with npm, pnpm and bun, and practical usage guidance.
This article details Alipay’s technical journey of refactoring the MyTab feature across Android, iOS, and HarmonyOS using Kotlin Multiplatform, covering architectural shifts, performance bottlenecks, stability fixes, and the resulting gains in code reuse and development efficiency.
Alipay tackled exploding bundle sizes, code‑reuse pain, and architectural complexity by redesigning its engineering stack into a standardized, plug‑in component system that reduced the main app by 47 MB, the pre‑install package by 127 MB, and cut baseline‑sync modifications from dozens to single‑digit numbers.
This article presents a KMP‑centric solution that uses Kotlin/JS to compute Compose UI on the JS side and Skia PictureRecorder on the native side, enabling block‑level, script‑driven dynamic UI embedding in native Compose pages without WebView or additional rendering stacks.
Ant Design 6.0 and Ant Design X 2.0 were officially released at SEE Conf 2025, introducing smooth migration from v5, raising the minimum React version to 18, adopting pure CSS‑Variables, enabling React Compiler in the build, revamping component semantics, dropping IE support, and adding several new components such as Masonry, enhanced Tooltip, spinner‑style InputNumber, draggable Drawer, and blur‑mask overlays, with a clear upgrade guide and future roadmap.
This article details how Alipay's engineering team built an AI‑Agent‑powered coding assistant for Kotlin Multiplatform (KMP) native cross‑platform development, covering architecture, UI generation from designs and images, RAG‑based knowledge retrieval, crash analysis, and future directions for AI‑driven software engineering.
Ant Design 6 drops IE support and adopts CSS variables, enabling smaller CSS bundles, easier theming, streamlined style overrides, conditional container queries, and scoped styling, while outlining practical code examples and compatibility considerations for modern browsers.
MYKMP is Alipay’s native cross‑platform solution built on Kotlin Multiplatform and Compose, enabling a single codebase to run on Android, iOS and HarmonyOS, with detailed architecture, engineering practices, GC optimizations, and integration guidelines presented for billion‑scale applications.
The open‑source UI‑UG‑7B multimodal model from Alipay combines UI understanding and generation in a single framework, delivering state‑of‑the‑art performance across referring, grounding, captioning, and code generation tasks while dramatically speeding up UI creation for developers.
Alipay’s AI research team, together with Ant Group and East China Normal University, leveraged a self‑developed large‑model‑plus‑optimization framework to create a constraint‑aware multi‑agent system that won both the Original OS Track and DSL Track at the IJCAI‑2025 Autonomous Travel Itinerary Planning Competition.
