Overview of SDK Modules

The Hyperledger Fabric SDK for Node.js provides a powerful API to interact with a Hyperledger Fabric blockchain. The SDK is designed to be used in the Node.js JavaScript runtime.

The Hyperledger Fabric SDK for Node.js is designed in an object-oriented programming style. Its modular construction enables application developers to plug in alternative implementations of key functions, such as crypto suites, the state persistence store, and logging utility.

The SDK is made up of four top-level modules, which we will discuss next.
