Hyperledger Composer has a modular architecture and is designed to support multiple runtimes (typically blockchain platforms).

There are currently 4 runtime implementations

  • HLF (the Hyperledger Fabric v0.6 runtime)
  • HLFv1 (the Hyperledger Fabric v1 runtime, currently supports v1-beta1)
  • Embedded (simulates a blockchain in memory in a Node.js process, good for unit testing)
  • Web (simulates a blockchain in a web browser, storing state in local storage, used for Playground when using a web connection profile).

This modularity is achieved via the core composer-runtime module, which is the core JS code that is common across all runtimes. There is then a composer-runtime-xxxx module for each supported runtime, as well as a composer-connector-xxxx module that exposes the runtime out of process to the Playground.

In the future we would love to see Composer support for other blockchains.

The runtime architecture was covered in a recorded community call on June 29th 2017. The recordings are available here: https://drive.google.com/drive/folders/0B_NJV6eJXAA1SDdTTjNmRktRdUk
