A simple tool to convert a WebAssembly module (wasm32-wasi, wasm32-freestanding) to a WASI component (component model, WASI-preview2).

Installation

Precompiled binaries are available for:

• Linux/x86_64 (.tar.gz and .deb)
• Linux/aarch64
• MacOS/aarch64
• Windows/x86_64
• Windows/aarch64
• WebAssembly (WASI)

Usage

Give the tool the WebAssembly module to process, and output file name, and that's it!

Example:

wasi-update -i module.wasm -o component.wasm

Compilation from source

Or if you really want to compile from source, install Rust and type:

rustup target add wasm32-unknown-unknown
cargo install wasi-update
