Questions tagged [hyperledger-fabric-sdk-js]

Use this tag for questions based on how to interact with ledger using NodeJS SDK, please don't use this for questions based on Fabric Infrastructure & chaincode related questions.

Hyperledger Fabric is the operating system of an enterprise-strength permissioned blockchain network. For a high-level overview of the fabric, visit http://hyperledger-fabric.readthedocs.io/en/latest/.

Applications can be developed to interact with the blockchain network on behalf of the users. APIs are available to:

  • create channels
  • ask peer nodes to join the channel
  • install chaincodes in peers
  • instantiate chaincodes in a channel
  • invoke transactions by calling the chaincode
  • query the ledger for transactions or blocks

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. https://fabric-sdk-node.github.io/release-1.4/index.html
