• The First Libra Wallet POC— Building your own Wallet and APIs

Architect

To build that APIs we need shell interactive that can send requests to Libra-cli so we use Node.js with child_process and rauschma/stringio libs to run a Libra-cli container every time when the user makes a request (stateless).

Required

• node 12 or latest
• docker
