Cardano Ogmios TypeScript Client Packages - REPL

A Node.js REPL which exposes the client behaviour in a terminal. Loaded into the context are the client builder functions, isolated query functions, and an instance of ChainSyncClient as chainSync with handlers to log the returned data. On exit the chainSync instance is shutdown. Optionally pass --host and --port arguments to specify the Ogmios server connection.

Quick Start
