Hyperledger Composer API

Hyperledger Composer is an application development framework for building Blockchain applications based on Hyperledger. This is the JavaScript documentation for the Hyperledger Composer Client, Admin, and Runtime JavaScript APIs.


The major components of Hyperledger Composer are:

  1. The Hyperledger Composer language for describing the structure of resources (assets, participants
    and transactions) that participate in a blockchain backed business network.
  2. JavaScript APIs to query, create, update and delete resources and submit transactions
    from client applications. Hyperledger Composer resources are stored on the Blockchain.
  3. JavaScript transaction processor functions that runs on Hyperledger Fabric when transactions are
    submitted for processing. These functions may update the state of resources
    stored on the Blockchain via server-side Hyperledger Composer APIs.
