About

This project is a bitcoin library, it is the implementation of the exercises and the book Programming Bitcoin by Jimmy Song in JS.

Quick start

Run tests

npm run install
npm run test

Some tests are skipped since they are currently calling to the blockchain.info API, in order to run then, just remove the skip call.

Find circular dependencies for a file (not needed)

Node will just import an empty object when we try to import a file with a circular dependency, the below commands are useful to debug this kind of issues.

1. Install madge globally (if not already installed)

   npm -g install madge

2. Find circular dependencies for a file:

   madge -c src/transaction/Tx.js

VS Code Setup:
