As of the 29th August 2019, the Hyperledger Composer project is in deprecated status. None of the maintainers are actively developing new features. None of the maintainers are actively providing support via GitHub issues. However, if you wish to submit code changes via pull requests, these will be merged.
It is highly recommended that you use Hyperledger Fabric v1.4+ instead, which features significant improvements to the developer experience, including a new programming model.
More information available here: What's new in Hyperledger Fabric v1.4
You must install Lerna to build this multi-package repository.
$ npm install -g lerna
Once Lerna is installed, and this repository is cloned, then you must bootstrap the repository so that all of the dependencies are installed and all of the packages are linked together:
$ lerna bootstrap
You can then work with the packages under packages/ on a per-package basis as any normal node.js package.
Alternatively, you can execute npm commands across all of the packages at once using Lerna:
$ lerna run test
