Zero-copy memory for WebAssembly
npm i @hazae41/memory.wasm
import { ExampleWasm, Memory, example_method } from "@hazae41/example.wasm";
// Wait for initialization
await ExampleWasm.initBundled();
// Pass bytes to memory
using memory = new Memory();
// View bytes from memory
console.log(memory.bytes)
// Call method with 0-copy
example_method(memory)
You need to install Rust
Then, install wasm-pack
cargo install wasm-pack
Finally, do a clean install and build
npm ci && npm run build
You can build the exact same bytecode using Docker, just be sure you're on a linux/amd64
host
docker compose up --build
Then check that all the files are the same using git status
git status --porcelain
If the output is empty then the bytecode is the same as the one I commited
Each time I commit to the repository, the GitHub's CI does the following:
docker compose up --build
git status --porcelain
output is not emptyEach time I release a new version tag on GitHub, the GitHub's CI does the following:
npm diff
between the cloned repository and the same version tag on NPMIf a version is present on NPM but not on GitHub, do not use!
