WebAssembly port of Base64 and Base64URL
npm i @hazae41/base64.wasm- Reproducible building
- Pre-bundled and streamed
- Zero-copy memory slices
- base64ct
- Base64
- Base64URL
import { Base64Wasm, base64_encode_padded, base64_decode_padded } from "@hazae41/base64.wasm";
// Wait for WASM to load
await Base64Wasm.initBundled();
const bytes = crypto.getRandomValues(new Uint8Array(256))
using memory = new Memory(bytes)
const text = base64_encode_padded(memory)
using memory2 = base64_decode_padded(text)
console.log(memory2.bytes)You need to install Rust
Then, install wasm-pack
cargo install wasm-packFinally, do a clean install and build
npm ci && npm run buildYou can build the exact same bytecode using Docker, just be sure you're on a linux/amd64 host
docker compose up --buildThen check that all the files are the same using npm diff
npm diffIf the output is empty then the bytecode is the same as the one I commited
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!
