It is meant for discussion, prototype specification and implementation of a proposal to add garbage collection (GC) support to WebAssembly. See the overview for a high-level summary and rationale of the proposal.

Oct 31, 2023 · In this blog post, the focus is on such garbage-collected programming languages and how they can be compiled to WebAssembly (Wasm). But what is garbage collection (often referred to as GC) to begin with? Note: The present article covers the concepts behind WasmGC in …

Nov 1, 2023 · Briefly, the GC proposal for WebAssembly (“WasmGC”) allows you to define struct and array types and perform operations such as create instances of them, read from and write to fields, cast between types, etc. (for more details, see the proposal overview).

The sole purpose of the Wasm type system is to describe low-level data layout, in order to aid the engine compiling its access efficiently.

Oct 18, 2023 · In a browser, Wasm GC objects are essentially allocated on the same heap as JS objects. Hence, references to both can be passed back and forth between Wasm and JS for free. (Conceptually, Wasm memory objects are also allocated on this heap, although with somewhat special techniques.

Nov 25, 2024 · This month’s v27.0 release of Wasmtime—the fast, secure, and standards-compliant WebAssembly (Wasm) runtime—includes enhancements such as completed support for the new Wasm garbage collection proposal, a PyTorch backend for wasi-nn, link-time feature gate configuration for unstable WIT APIs, and more.

Oct 30, 2024 · WebAssembly’s Garbage Collection (WasmGC) extension transforms front-end development by making it possible to run complex languages like Java in browsers, efficiently managing memory demands that were previously unmanageable without …

The WebAssembly GC proposal is a game changer for high-level programming languages, offering the potential to streamline memory management, reduce module sizes, and improve execution speed. This proposal significantly reduces the need for languages to inject complex runtime code to manage memory, making WebAssembly applications built from these ...

Support for garbage collection within WebAssembly (WASM-GC) will bring a host of new languages and frameworks to the web app space. Learn how the Dart and Flutter teams at Google are building on WASM-GC (among other upcoming standards) to bring richer, faster, more consistent applications to the web

Jan 1, 2024 · If compilers generate Wasm code with those new WasmGC types and instruction (WasmGC primitives), then the Wasm code can be executed with GC, in the runtime that supports WasmGC. In this article, we will explore the new types …
