🐕 Optimization practice of h5 page opening in seconds on iOS terminal

The usual methods include resource cache, offline package, data Prefetch, etc. In this paper, the author first analyzes the process of H5 page loading, and realizes the mechanism of resource caching on iOS based on WkWebview through request interception.

🐎 Blockbuster | skilled and magical craftsmanship, Flutter for the Web
As we all know, Flutter Web support has been added in version 1.9, but only in the technical preview. This article compares the mobile terminal principle with the Web method, and intuitively feels the difference between them (mainly in dart: UI and Engine).
Advantages: better compatibility with HTML + CSS + Canvas, low cost migration (direct compatibility with the upper layer of Flutter) Disadvantages: Dart2JS generates too much code and is not fully functional. The BitmapCanvas used can cause performance problems in some zoom scenes
With such an excellent layered design, Flutter Web is worth waiting for until a usable version is available.

Based on NSProxy development to support data binding, event binding library
@Smiling drinking arsenic: GICDataBinding is a data binding library based on NSProxy. It supports data binding (one-way, bidirectional) and event binding. Importantly, it supports JS expressions, as well as Swift, but the data type in Swift must be NSObject. Based on the GICDataBinding data binding system, it is possible to do some functions which are complicated to implement before, such as rethinking the definition of ViewModel, JS ViewModel, and realizing the responsive design of the whole UI based on the binding system with Texture.
