awesome_app

Follow these instructions to use the project (tested on my machine, Ubuntu 18.04).

1. Get HyperLedger Fabric prerequisites: https://hyperledger-fabric.readthedocs.io/en/latest/prereqs.html

   These include docker, docker-compose, cURL and Git for Linux. You probably already have most, if not all of these.

2. Install the Fabric binaries and samples https://hyperledger-fabric.readthedocs.io/en/latest/install.html.

   This will add a fabric-samples folder to your machine in the directory you are installing. The Fabric samples are a collection of Fabric sample projects. They can be found here: https://github.com/hyperledger/fabric-samples

3. Make sure you have these Fabric Node SDK requirements: https://github.com/hyperledger/fabric-sdk-node#build-and-test.

• Node.js, version 10 is supported from 10.15.3 and higher
• Node.js, version 12 is supported from 12.13.1 and higher

I use node version 12.18.1 Check node version with command:

node -v

• npm tool version 6 or higher

I use node version 6.14.5 Check node version with command:

npm -v

• docker - Should already be installed from step 2.

4. Clone this repository https://github.com/venoivankovic/awesome_app into the Fabric samples folder.

5. Change directory to the awesome directory you cloned into the Fabric samples folder:

   cd awesome
   

6. Change into the apiserver directory:

   cd apiserver
   

7. From here you install the node dependencies, run command:

   npm install
   

   Repeat this with awesome_webapp directory:

   cd awesome_webapp
   

   npm install
   

   You will only need to install node modules once.

8. Run script startFabric.sh from top level awesome_app directory:

   ./startFabric.sh
   

9. Once this has finished cd into the apiserver directory:

   cd apiserver
   

   Then run the setupCommands.sh script. This will register 3 providers, 3 customers and 5 witnesses on the DApp. You can edit this file as you wish.

   ./setupCommands.sh
   

   After this you can run the apiserver.js file. This will start the API server on port 8080.

   node apiserver.js
   

10. Then simply start the gui component, here it is on port 8081, choose any free port.

cd awesome_webapp

node app 8081

11. To use the DApp navigate to http://localhost:8081/. For each user open a new tab.
