This repo is the home of BitGo's WASM libraries.

• Rust nightly
• wasm-pack (install with cargo install wasm-pack)
• Node.js

npm install

This will:

• Install all dependencies
• Set up pre-commit hooks via Husky

Pre-commit hooks automatically run on staged files:

• JS/TS: Prettier formatting + ESLint
• Rust: cargo fmt + cargo clippy

This monorepo uses Lerna for managing package versions and publishing to npm.

Packages use independent versioning with Conventional Commits to automatically determine version bumps:

• fix: commits trigger patch releases (0.0.x)
• feat: commits trigger minor releases (0.x.0)
• BREAKING CHANGE: in commit body triggers major releases (x.0.0)

Publishing is automated via GitHub Actions when changes are pushed to master or beta branches. The workflow:

1. Builds all packages
2. Runs tests
3. Uses Lerna to analyze commits since last release
4. Automatically versions and publishes changed packages

To manually publish (if needed):

npx lerna publish

To see what would be published without actually publishing:

npx lerna changed

This is a wrapper around the rust-bitcoin and rust-miniscript crates that is compiled to WebAssembly.

A live playground for the wasm-utxo crate.
