Fabric 2.0.0 Hello World (Node.js)

Deploying sample app in development mode (no TLS, 1 Org, Peer running in dev mode, CouchDB, and solo orderer)

To deploy the fabric network, in the network directory run:

./start.sh

In smartcontracts/contract run

npm install

To install the smart contract in smartcontracts/contract, in the smartcontracts directory run:

./deploy.sh

At the end something like the following should appear:

===========================
RUN:
===========================
CORE_CHAINCODE_ID_NAME=fabcar_1:3e4857d57fc322fd8eba0b1d4e21a03446f74f895dfa2228a874c8331f1dea72 CORE_PEER_TLS_ENABLED=false node ./contract/index.js --peer.address 127.0.0.1:7052

Run that command so that the smart contract in the smartcontracts/contract runs in development mode. Logs should appear in that terminal.

Then to initialize the smart contract in the smartcontracts directory run:

./initChaincode.sh

To run the application that connects to fabric in apps/application run:

npm install
node ./enrollAdmin.js
node ./registerUser.js

node ./query.js
node ./invoke.js

Then to start express web server on port:3000 use:

npm start

The Swagger documentation will be in /api-docs Fauxton (to view CouchDB) will be in port:5984/_utils/

To stop the fabric network in network run (in some cases it might require sudo):

./stop.sh

Deploying sample app with 1 or 2 Organizations (TLS enabled, CouchDB, and etcd orderer)

Like deploying in dev mode except the scripts receive a flag -n 1 or -n 2 indicating the number of organizations in the network.

In network:

./start.sh -n 2

In smartcontracts:

./deploy.sh -n 2
./logs.sh

In apps/application:

npm install
node ./enrollAdmin.js
node ./registerUser.js

node ./query.js
node ./invoke.js
npm start

In network:

./stop.sh -n 2
