Ledger Live Common (@ledgerhq/live-common) is a JavaScript library available via a NPM package.

This library depends on a bunch of ledgerjs packages and put together the core business logic behind Ledger Live Desktop and Ledger Live Mobile.

The stack is pretty standard for a ES6 and FlowType library. The notable dependencies are libraries like RxJS and BigNumber.js. There is also a bit of React and Redux but exposed in agnostic ways (meaning it's not mandatory to use – there will be dedicated entry point for them to offer utilities like React Hooks).
