由于当前 Wasm 标准下，Wasm 模块不能直接操纵 dom 元素，所以 WebAssembly 主要应用在了一些计算密集型的场景下，视频的解码编码、图像处理、涉及到复杂计算的算法、加密算法等等。 不止于Web. Wasm 除了应用在浏览器中，也可以应用到 out-of-web 环境中。

Dec 22, 2024 · 从理论上来说，wasm应该是比js小，但是很多编程语言编译出来普遍比js大。因为很多编程语言编译的代码包裹了一个gc，而js小的原因是浏览器自带了js的gc。如果其他语言用上了浏览器自带的wasm gc，打包出来的代码就会小很多，不过wasm gc完善还遥遥无期。

WASM itself isn't a "thing to learn" btw, you're writing code in a lower level language (Rust, C(++), etc.) which is compiled to a .wasm binary. You could learn those languages individually or just enough to solve a true problem , (to me) the true understanding comes in how to use it within the context of a web app.

Apr 27, 2023 · If you just deploy a dev build it still uses wasm caching. If you look at the difference between service-worker.js and service-worker-published.js, you'll see the caching in the published version. For us, we just replaced the contents of the latter, with the former, so all wasm caching by the service-worker process is ignored.

May 5, 2022 · Uh, 2x faster is a hell of a lot faster. And it will get even faster once there is better JS-Wasm interop. It’s just not worth rewriting an app in Rust to achieve a 2x client side speed up for most projects, though. Also, if Wasm and the Rust toolchain get proper FDO support, I bet it will beat V8. Not to mention that Wasm latency is far far ...

WASM in 2024 - no thread, audio stutter because you can not make web-audio worker thread (you can but it wont work on Apple). That also leads to very laggy experience of everything that use WASM module - like UI that use wasm-functions will have insane input delay because WASM UI-logic will be processed in single thread.

Oct 11, 2022 · Methods to force browser cache refresh on Blazor WASM apps Hi folks, I have a WASM app stored in an AWS S3 bucket and distributed using Cloudfront. I updated a few files recently, invalidated the Cloudfront cache, and after a …

Jun 1, 2023 · I have a Blazor WASM site that I've deployed 20-30 instances of for various customers. They run independently, but on the same servers. All run the same version of code, on their own subdomains with their own separate databases. The sites work fine, and speed is fine, responses are fine.

May 17, 2022 · NET team is leveraging AOT compilation with trimming support when targeting webassembly. Yes, they also compile the runtime but they are aiming for smaller wasm modules running at near native speed. Worth keeping an eye on. Net since they have the best web development story (wasm-related).

JS 与 WASM 的双向调用并不像 Python 嵌入 C 那么简单，你不能随便把 JS 里的对象直接交给 WASM，至于喊着打通一切运行时类型的 WASM Interface Types 才刚有了个影子。 主流前端 UI 框架未必值得用 WASM 重写，它们的场景是 IO 密集的，换语言彻底重写的投入产出比很难说 ...
