One of the biggest pains of getting started with Fabric, even though it's a powerful framework, is getting the infrastructure to work. This small tutorial will get you up and running in less than minutes. No script. No pain. I'm still surprised how hard it is for some people to get started with Fabric, I know that many just quit because they feel like it's not worth it. is a tool to create immutable setups for with just one command. Hurley development blockchain networks Just be sure you meet Fabric requirements: NodeJS 8.1x - install if you have a latter version. NVM If you are using Ubuntu or other Linux distros it may be good to follow this guide: https://docs.worldsibu.com/article/120-install-on-ubuntu Install (CE). Docker Community Edition Install the CLI tool: npm install -g @worldsibu/hurley All good so far? Now to create a network you need to do: hurl new This will create a default network in your local Docker. Two organizations Two peers, one CouchDB each What if you want more organizations or channels? hurl new -o 3 -c 3 This will create 3 organizations with three channels ready to be used. Beware that Hurley creates immutable setups, once you deploy the network you can't change the environment through the tool. You can manually do it, but I'd advice against it, for development you want something clean and easy to start/kill in a predictable way. Hurley not only manages your development network but also helps you installing your chaincode and calling it. Get into the source code of your project to install it like. If using golang: hurl install yourchaincode golang If using node: hurl install yourchaincode node Haven't bootstrapped your own project yet? I'm leaving some instructions at the end of this file on how to create a new project for nodejs with Convector in the section "Actual example with a new chaincode". Once you have installed your chaincode you can send transactions like this: hurl invoke yourchaincode invoke "param" You send the params as an array separated by a blank space. Actual example with a new chaincode: npm i -g @worldsibu/convector-cli conv new example example npm install npm run cc:package -- example org1 hurl new hurl install example node -P ./chaincode-example hurl invoke example example_create # Install a tool to bootstrap your project # Create a new smart contract code project # get to the project to see the source code cd # Resolve dependencies # Package the project # Start your blockchain network # Install the smart contract # Wait a few seconds # Send the first transaction '{"id":"1", "name": "example", "created": 1000, "modified": 10000}' Now you can go to the CouchDB installed by Hurley to see the resulting data of the transaction: http://localhost:5084/_utils/#database/ch1_example/_all_docs Other interesting content for you once using Hurley: How to find logs in the network? .
