Install nodered in ubuntu

-
Before you can install Node-RED, you must have a working install of Node.js. We recommend the use of Node.js LTS 8.x. Users of Node.js 6.x and 4.x should ensure they have the latest updates. Node-RED no longer supports Node.js 0.12.x or 0.10.x.

Linux and OSX users should install the packaged version of Node.js for your specific operating system, or get the latest Long Term Support (LTS) version from the download site.
To check your version of Node.js
node -v
Other download options are available here.
The easiest way to install Node-RED is to use the node package manager, npm, that comes with Node.js. Installing as a global module adds the command node-red to your system path:
sudo npm install -g --unsafe-perm node-red

Next

Once installed, you are ready to run Node-RED.

Running

If you have installed Node-RED as a global npm package, you can use the node-red command:
$ node-red

Chaincode Development Introduction For the first five days, we have seen the concepts of Hyperledger fabric and various components of it. We have started our own network, deployed the simple smart contract. We have done transactions, we transferred data privately. In this part we are going to look into Chaincode development aka smart contract development for Hyperledger Fabric. We know that chaincode is running in different docker container once it is instantiated on channel isolating from the peers. Typically smart contract is the business logic agreed by the members to execute with consensus. However within the same network multiple many chaincode might be running on different channels. “Without appropriate permissions a chaincode cannot invoke another chaincode”. Various levels of Chaincodes There are two perspective on chaincodes. First, the perspective of the developer who is developing blockchain application — Chaincode for developers Second, the bl...
