privEOS_Demo_App

Demonstrating a frontend connected to the priveos smart contract and node services to upload, list and download files based on transactions.

Environments

You can switch between localhost and jungle2 (default). To connect to localhost, append url param: ?env=localhost or set localStorage item:

localStorage.setItem('env', 'localhost')

To be able connecting to localhost, you need to have the following processes running:

1. EOS node with privEOS smart contract
2. IPFS node
3. MongoDB (only if mongodb plugin is used by EOS)

Prerequisites

Ensure you have the following global bash utilities installed:

1. jq (for deployment to ipfs only, see bin folder)
2. webpack
3. yarn or npm

The webpack production build does not work with node version > 8.9.0!

Priveos Client Library

The frontend requires the priveos client library. To link it, run:

# in priveos-client folder:
npm link

# in privEOS_Demo_App/frontend folder:
npm link priveos

Production Build

To create an optimized production build, run:

cd frontend
yarn build

Local Development

To start the local development frontend, run:

cd frontend
yarn start

It will then start a local development server with live reload. The default configuration does connect to jungle2 testnet, so no full node required but you apparently you need to have ipfs running to up- and download files:

ipfs daemon

If you do not have ipfs installed, see this section:

Install IPFS

brew install ipfs
ipfs init
ipfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["*"]'
brew services start ipfs

Deploy to IPFS

Start an ipfs daemon. Then run:

bin/deploy-to-ipfs
