Hyperledger Composer is a JavaScript application development framework for building blockchain applications on Hyperledger Fabric, providing a business-network modeling language, CLI tools, and a web playground. The project was officially deprecated in August 2019 and its capabilities were folded into Hyperledger Fabric v1.4+.
Use cases
- build blockchain applications on hyperledger fabric
- model a business network for a distributed ledger
- generate REST APIs for a blockchain network
- prototype smart contracts with a modeling language
- learn blockchain development with a playground
When to choose
- maintaining or reading a legacy codebase that already uses Composer
- studying historical blockchain application frameworks
- submitting patches to an existing Composer deployment
When to avoid
- starting any new blockchain project - it is deprecated with no active support
- building on Hyperledger Fabric v1.4+ - use the native Fabric SDK and programming model instead
- expecting bug fixes or GitHub issue support from maintainers
