Full-Stack Dapp using Solidity, Ether.js, Hardhat, and React JS | Code Eater - Blockchain | English

[@codeeaterweb3971]

Facing Errors 🔴🔴 If you are facing any errors then please use the same dependency version as I am using here - github.com/kshitijofficial/coffeDapp/blob/main/package.json and github.com/kshitijofficial/coffeDapp/blob/main/client/package.json Most of the time the error are because of ethers.js. So please use ethers js 5 version only.

how to use ehters js how did not state it in video

[@MilesArray]

Great video on building a full-stack dApp with Solidity, Ether.js, Hardhat, and React JS. It's impressive how these tools come together to create something so powerful. For any devs watching, don't forget how SubQuery can make handling data a breeze, adding even more efficiency to your projects. It’s a game-changer for the web3 space!

[@ronrawi7129]

Thanks so much, i have completed this video. It is a practical way to build DApp. Your template is working perfectly.
