Move Binary Format

This crate builds a WASM binary for the move-language/move-binary-format allowing bytecode serialization and deserialization in various environments. The main environment this package targets is "web".

Usage in Web applications

The package consists of code and a wasm binary. While the former can be imported directly, the latter should be made available in static / public assets as a Web application. Initialization needs to be performed via a URL, and once completed, other functions become available.

import init, initSync, * as wasm from '@mysten/move-binary-format';

await init('...path to /move_binary_format_bg.wasm');
// alternatively initSync(...);

let version = wasm.version();
let json = wasm.deserialize('a11ceb0b06....');
let bytes = wasm.serialize(json);

console.assert(json == bytes, '(de)serialization failed!');

Build locally

To build the binary, you need to have Rust installed and then the wasm-pack. The installation script can be found here.
