      Description

      What's the format of the chaincode source?

      • chaincode should be written as CommonJS modules and be launch-able with the node.js engine

      How does the chaincode get discovered and loaded into the node.js app?

      • a package.json must accompany is chaincode sources, in the root folder of the "chaincodePath" parameter during chaincode install. The package.json is critically important for two purposes:
        1. specifies any dependencies, including the fabric-shim package itself which is needed by all JS chaincodes, and any other external dependencies
        2. using the "scripts" section to specify how the chaincode should be launched:
            "scripts": {
              "start": "node mychaincode.js"
            },

      Do we allow JS chaincodes to have other source dependencies? in other words can a JS chaincode by broken up into multiple modules?

      • yes definitely

      How do we ensure multiple install operations produce the same binary from npm install?

      • use best practices with shrinkwrap.json
