memory.wasm

Zero-copy memory for WebAssembly

npm install @hazae41/memory-wasm

📦 NPM

Features

• Reproducible building
• Pre-bundled and streamed
• Zero-copy memory slices

Usage

import { exampleWasm } from "@hazae41/example-wasm";

// Wait for initialization
await exampleWasm.initBundled();

// Pass bytes to memory
using memory = new exampleWasm.Memory();

// View bytes from memory
console.log(memory.bytes)

// Call method with 0-copy
exampleWasm.example_method(memory)

Building

Reproducible building

You can build the exact same bytecode using Docker

npm run compile && npm run prepack

Then check that all the files are the same using npm diff

npm diff

If the output is empty then the bytecode is the same as the one I published on NPM.

Automated checks

Each time I release a new version on GitHub, the GitHub's CI clones the GitHub repository, reproduces the build, and throws an error if the NPM release is different. If a version is present on NPM but not on GitHub, do not use it!
