Swift for Wasm April 2026 Updates

Notable changes this month: Wasm-compatible swift-tar library, JavaScriptKit 0.50.0–0.51 releases with continued BridgeJS work and a new opt-in pointer-identity mode for SwiftHeapObject wrappers, WasmKit updates unifying WasmKitError typed throws and removing any GuestMemory existentials from *Guest*Pointer types (plus a small 0.2.2 patch release), and ElementaryUI 0.2.0–0.2.2 focused on performance and stability fixes. Many thanks to 0xpablo, @inductor, @kateinoigakukun, Ken Tominaga, @krodak,...

🌗 在 WebAssembly 中將 Tar 封存檔掛載為檔案系統
➤ 透過索引技術實現 WebAssembly 的檔案系統零複製掛載
✤ https://jeroen.github.io/notes/webassembly-tar/
處理網路上的 .tar.gz 檔案時，傳統做法通常需要下載、解壓縮並複製所有檔案，這在記憶體有限的環境中非常耗時且昂貴。本文介紹了一種創新的優化方案：利用 Emscripten 的 WORKERFS，透過生成一個包含檔案偏移量（offset）與大小的 JSON 索引檔，將 .tar.gz 檔案直接掛載為虛擬檔案系統。此方法無需複製原始資料，直接透過記憶體映射（memory-mapping）技術實現零複製讀取，顯著提升了載入效率。
+ 這對於在瀏覽器端載入大型資料庫或語言套件（如 R 語言）簡直是神級優化，原本繁瑣的解壓縮步驟現在幾乎零成本。
+ 很有趣的技巧。利用 Tar 格式本身扁平且具備位元組定址的特性，配合瀏覽器原生的 DecompressionStream，確實將資源利用

Mounting tar archives as a filesystem in WebAssembly

How to use a file index to mount a tar.gz archive directly into the Emscripten virtual filesystem without extracting it

ʕ•ᴥ•ʔ Notes from Jeroen

N-gated Hacker News Apr 24

Oh, look! Another attempt to solve the monumental crisis of handling tarballs—this time with #WebAssembly and a sprinkle of #Emscripten magic. 🙄 Instead of just extracting a file like a normal person, let's generate an "index" to mount things because who doesn't love an overengineered solution to save a few bytes? 😂

Just posted a new devlog for our C-based web engine, Archimedes!

It's been a long road from Pygame to a custom C/Emscripten stack. I'm breaking down the architectural hurdles of moving away from our Daedalus library and how my collaborator @smattymatty has been stress-testing the engine with a vampire survivors clone and recent game jams.

To celebrate the progress, I've rewritten my old ( and very broken ) Game of Life simulator from the ground up. It's a great feeling to see a legacy project running smoother than ever on new, custom-built foundations.

Long shot, but is there anyone here who has used SDL3 and Emscripten or is familiar with building Emscripten from source?

I had to get SDL3_TTF from a PR, and managed to build it with embuilder but so far when I try to build with -sUSE_SDL_TTF=3 it doesn't seem to acknowledge the option and if just complaining that it can't find SDL3/SDL_ttf.h

What am I missing?

(also if you don't know, sharing is caring)

emsdk-env makes public.

This is a Vite plugin that automatically downloads and manages the Emscripten SDK, and makes it possible to automatically build WASM C/C++ code in your project.

With this plugin, you can easily set up a WASM C/C++ development environment in your Vite project.
