Ethereum-CV-Sharepoint

An introductory application to using Ethereum with Angular, Truffle, Ganache and IPFS. It will represent a sharepoint for saving and sharing files (in our case CV's) onto the blockchain. More specifically storing their hash in the contract and saving the actual file onto IPFS.

Prerequisites

• Node.js
• Docker
• Metamask Extension

Setup

• clone the repository git clone https://github.com/antonio-marasescu/Ethereum-CV-Sharepoint.git
• run npm install
• run docker-compose up in the docker folder
  • ganache accounts will be listed in the console terminal
• run npm run migrate --hard to deploy and compile the contracts
• run npm run ng to start the angular application

For Issues regarding CORS when using IPFS on docker

After docker-compose use in the container console the following commands:

ipfs config Addresses.Gateway /ip4/0.0.0.0/tcp/8080
ipfs config Addresses.API /ip4/0.0.0.0/tcp/5001
ipfs config --json API.HTTPHeaders.Access-Control-Allow-Methods '["PUT", "POST", "GET"]'
ipfs config --json API.HTTPHeaders.Access-Control-Allow-Origin  '["http://localhost:4200"]'
