Hyperledger Composer is not a universal solution to all the complexities presented by Hyperledger Fabric. It takes away some of the flexibility over tasks that could be customized without it. What it does do, however, is supply a toolkit to create chaincode projects, build blockchain application packages (.bna files), and deploy them to Hyperledger Fabric.

The development of a business network using Hyperledger Composer is focused on creating assets, participants, transactions, queries, and access control lists using a project structure and a common language. After creating the business network definition, Composer has tools to package and deploy the application to a Hyperledger Fabric platform.
