Yeoman generator for Hyperledger Fabric.
This Yeoman generator can be used to generate chaincodes, or smart contracts, for Hyperledger Fabric. Chaincodes can be generated that are written in either Go or JavaScript, with experimental TypeScript support available as well.
You must install Yeoman, which is easy:
npm install -g yo
Then you can install this Yeoman generator, which is also easy:
npm install -g generator-fabric
Done!
Create a new directory for the chaincode:
mkdir my-smart-contract
Change into the new directory for the chaincode:
cd my-smart-contract
Create an empty git repository for the chaincode (optional, but recommended):
git init
Run the Yeoman generator:
yo fabric
If everything is installed successfully, then you should see prompts similar to the following:
? Please specify the generator to run: Chaincode
This generator can also be run with: yo fabric:chaincode
? Please specify the chaincode language: JavaScript
? Please specify the chaincode name: my-smart-contract
? Please specify the chaincode version: 0.0.1
? Please specify the chaincode description: My Smart Contract
? Please specify the chaincode author: Simon Stone
? Please specify the chaincode license: Apache-2.0
create package.json
create .editorconfig
create .eslintrc.js
create .gitignore
create index.js
create start.js
create lib/chaincode.js
create test/chaincode.js
Alternatively, you can run the generator non-interactively, by specifying additional command line options:
yo fabric:chaincode -- --language javascript --name my-smart-contract --version 0.0.1 --description "My Smart Contract" --author "Simon Stone" --license Apache-2.0
If you are running the contract generator non-interactively, you will also need to specify the contractType (either default or private) and the asset command line options, in addition to the above options. Please note that if you decide on generating a contract which makes use of private data, you will also need to specify the mspId as a command line option. For example:
yo fabric:contract -- --contractType private --mspId Org1MSP --language javascript --name my-smart-contract --version 0.0.1 --description "My Smart Contract" --author "Simon Stone" --license Apache-2.0 --asset "MyPrivateAsset"
