Getting started

Project Structure

This project consist of 2 directories the, the server(root directory) and the client for our front-end as follows:

• client/ : contains all the subfolders and files for our react frontend
• contracts/: Contains the Solidity smart contract files.
• scripts/: Contains JavaScript scripts to deploy and interact with the smart contracts.
• test/: Contains test scripts to test the functionality of the smart contracts.
• hardhat.config.js: Configuration file for Hardhat setup.
• index.js: Node js proxy server file to proxy our request from the client to the endpoint and vice versa
• README.md: This file.

and was developed with ❤️ using the following softwares:

1. React
2. Ethers
3. Node (Express)
4. Solidity
5. Hardhat
6. IPFS

Requirements

• git
  • You'll know you did it right if you can run git --version and you see a response like git version x.x.x
• Nodejs
  • You'll know you've installed nodejs right if you can run:
    • node --version and get an ouput like: vx.x.x
• Yarn instead of npm
  • You'll know you've installed yarn right if you can run:
    • yarn --version and get an output like: x.x.x
    • You might need to install it with npm or corepack

Quickstart

git clone https://github.com/chidubesteve/DeDrive-3.0.git
cd DeDrive-3.0
yarn
cd client && npm install && npm start
or
npm i
cd client && npm install && npm start

This will spin up our react app in the front end.

Usage

1. Run your local blockchain with the lottery code

In a different terminal / command line

npx hardhat node
or
yarn hardhat node

2. Add hardhat network to your metamask/wallet

• Get the RPC_URL of your hh node (usually http://127.0.0.1:8545/)
• Go to your wallet and add a new network. See instructions here.
  • Network Name: Hardhat-Localhost
  • New RPC URL: http://127.0.0.1:8545/
  • Chain ID: 31337
  • Currency Symbol: ETH (or GO)
  • Block Explorer URL: None

Ideally, you'd then import one of the accounts from hardhat to your wallet/metamask.

3. you can run the node proxy server in the root directory by

In a different terminal / command line

npm run dev or yarn dev

4. Head over to Pinata (Pinata is an IPFS and farcaster service provider provider) to get your api keys . Create a .env file and add them. NEVER PUSH YOUR KEYS TO REPO!!

5. Go to UI and have fun!

Head over to your localhost and upload, view and share your files

Testing

I have written test for the contract in the test folder

• you can run the tests by npx hardhat test or a specific test by adding a --grep flag followed by the name of the test eg: npx hardhat test --grep "it should do this"

Feel free to write more test cases 😀😀and you can also change the visibility of state variables in the contract to access the default getter and functions crested by solidity compiler

Deploying

1. Build your static code.

yarn build or npm run build
