As a part of the , we decided to spin out the libraries and turn them into an independent project. The main reason for that decision is that we know that it may be overwhelming to deal with the environment while also developing with Hyperledger Fabric and other frameworks. We always see people all the time in chats, channels, and blogs having a hard time with those tasks. It is a problem big enough to be its own product. Convector Suite Dev Env If you are not familiar with the take a look at this post: Convector Suite Announcing: Convector, a JavaScript Framework for Smart Contract Systems The has grown since launch 5 months ago. Initially, it was made only of libraries and a few utils to install and upgrade smart contracts during development. Convector Suite Convector Smart Contract A Convector Smart Contract looks like the following: A few months ago, Convector got its own , so setting up a new Convector project became a matter of one command line. CLI Check this example to contrast how a looks like versus vanilla Go or Node in Hyperledger Fabric. Convector Smart Contract The Convector CLI the best way to start a new project. But it still used fairly simple and fixed development environments. See the last two commands ( and )? Those get replaced with the newly created . npm run env:restart npm run cc:start -— toke 1 Hurley We all know that starting with new technology can be hard, so we are working on making it easier. is an inside the umbrella that enables developers to roll out development networks and streamline the development lifecycle with just a few commands. Hurley Open Source project Convector Suite Hurley is independent from . So it can work with it or without it. You can also use it to install and upgrade Golang and vanilla Node chaincode. Convector Smart Contracts Starting with Hurley is quite easy. Its only requirement is having up and running. Hurley will even download your Hyperledger Fabric dependencies. Docker CE $ npm i -g @worldsibu/hurley With this, now you can use in any folder path that you want. For example, let’s download the Fabric Samples to use those examples here. Hurley $ git clone $ cd fabric-samples https://github.com/hyperledger/fabric-samples.git Start yourself a blockchain network with 3 organizations and 2 users each organization, plus add 2 channels. $ hurl new --organizations 3 --users 2 --channels 2 Wait a few seconds (maybe minutes if you don’t have Fabric downloaded already). Now let’s go to the Fabric Samples project that we want to install. Be sure to run inside the folder where your source code resides. hurl install $ cd chaincode/fabcar/go/$ hurl install fabcar golang [hurley] - installing smart contract located at /Users/walter/Development/testhackhurley/fabric-samples/chaincode/fabcar/go ...2019-01-07 09:49:08.483 CST [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc2019-01-07 09:49:28.928 CST [main] main -> INFO 003 Exiting..... Voilà! You have successfully installed a smart contract yourself. If you were to make a change to the source code, and want to upgrade to code, just make the change and run. # change 1.2 for the new version of your smart contract$ hurl upgrade fabcar golang 1.2 streamlines the development lifecycle so that you can focus on business matters, like the design of the smart contract. Hurley After version of new projects will be generated supporting Hurley instead of the legacy Dev Environment. You can still run the same NPM commands or you can run Hurley commands directly if you installed it globally. 1.0.5 Convector CLI # Install a blockchain$ npm run env:restart # Install to your blockchain - From the root of your project$ npm run cc:start -- product$ npm run cc:start -- product 1.2 # Install a blockchain$ hurl new # Package your smart contract's code - From the root of your project$ npm run cc:package -- product org1 # Install to your blockchain - From the root of your projectcd ./chaincode-product$ hurl install product node$ hurl upgrade product node 1.2 The advantage of using Hurley directly is that you can do more complex tasks. Some examples: # Install a chaincode with a different name$ hurl install anothernameforyourcc node # Install a chaincode in a different channel$ hurl install <chaincode> node --channel ch2 # Install a chaincode in a path different than current$ hurl install <chaincode> node -P ./sourcecode/chaincode Find it helpful? We would love to hear from you. What do you think is the next feature that or Convector should support? Let us know in the .
