Native State Channel Utilities

This repository contains WASM and Node.js native bindings for various state channel utilities such as hashing states, signing states ad recovering signer addresses from signed states.

The repository contains one wasm-utils directory at the root. This generates a NPM package for the WASM utilities, which is written to packages/wasm-utils. This needs to be run before anything else.

After this, the package can be treated as a regular Lerna/Yarn monorepo.

The primary package in this repository is @statechannels/native-utils in packages/native-utils. This package depends on Neon and @statechannels/wasm-utils. When it is installed, it will try to find cargo (the Rust package manager). If Rust is available, it will build native Node.js bindings for the state channel utilities. If Rust is not available, it will fall back to using the WASM package behind the scenes.

Build

# This ensures that packages/wasm-utils/ is generated from wasm-utils/
yarn bootstrap

Publish packages to NPM

This will publish @statechannels/wasm-utils and @statechannels/native-utils.

yarn publish

Run test suite

This tests the native and WASM bindings.

yarn test

Run benchmarks

This compares the pre-existing utilities in Nitro Protocol / Server Wallet, the native bindings (if Rust is available) and the WASM bindings.
