It sits at the boundary between traditional object linking and the WebAssembly component model, wrapping LLVM's `wasm-ld` flow and then componentizing the result. ### Project history The repository was created on December 12, 2023, as the component model was becoming a practical build target rather than only a specification. Its README describes the binary as a wrapper around two operations: invoking the LLVM `wasm-ld` linker driver and then using `wit_component::ComponentEncoder` to produce a final component. The project is intentionally small and specialized. It exists because component-model artifacts need more than a core Wasm link step: metadata, WIT interfaces, adapters, and component encoding have to line up with the component model's interoperability contract. ### Adoption history wasm-component-ld follows the broader Bytecode Alliance push around WASI and the component model. The official component-model documentation frames components as a way to build interoperable WebAssembly libraries, applications, and environments, with user documentation for building, using, composing, and distributing components. ### How it is used The package is used by developers and language toolchain authors who need a command-line linker that emits a component rather than only a core module. In practice it belongs near C, C++, and other non-Rust workflows where LLVM already produces Wasm object files and the final artifact must become a component. ### Why package nerds care Its significance is not broad end-user adoption but toolchain plumbing. For package maintainers, it marks the arrival of component-model-specific linker binaries as installable system tools, similar to how `wasm-ld`, `wasm-tools`, and `wit-bindgen` occupy distinct slots in a modern Wasm toolchain. ### Timeline - 2023-12-12: Public GitHub repository created. - 2024-2026: Releases track ongoing component-model tooling work. - 2026-06-12: GitHub releases list v0.5.25 as the latest release at research time. ### Related projects - Related Bytecode Alliance tooling includes wasm-tools for inspecting and manipulating modules and components, wit-bindgen for interface bindings, cargo-component for Rust component builds, and LLVM's wasm-ld linker. ### Sources - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Other Package-Manager Records - Nix - wasm-component-ld: normalized package name match | nixpkgs package indexes: pkgs/by-name/wa/wasm-component-ld/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - apk - wasm-component-ld - 1.97.0-r0: normalized package name match | Alpine Linux edge package indexes: wasm-component-ld from https://dl-cdn.alpinelinux.org/alpine/edge/main/x86_64/APKINDEX.tar.gz | Command line linker for creating WebAssembly components | https://github.com/bytecodealliance/wasm-component-ld - pacman - wasm-component-ld - 0.5.28-1: normalized package name match | Arch Linux sync databases: wasm-component-ld from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | Command line linker for creating WebAssembly components | https://github.com/bytecodealliance/wasm-component-ld - MacPorts - wasm-component-ld: normalized package name match | MacPorts ports tree: lang/wasm-component-ld/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
