Alright, the series of articles goes to frontend part. I post an article related to Blockchain with React.js and Next.js. If you haven’t seen my previous posts Part 1 Introduction, Part 2 Hardhat, and Part 3 Golang Gin, please read them first.
In this article, I demonstrate how to use React.js (Next.js) to interact with smart contract by Golang Gin API and hardhat RPC URL, and implement a simple Sign-in with Ethereum (SIWE) authentication and setGreeting to Solidity.
Okay, let’s start it.
It’s time to Blockchain with Golang. If you haven’t seen my previous post Part 1 Introduction and Part 2 Hardhat, please read them first.
Again, does Dapp need a Backend?
- You can pretty much make a dapp without backend, but there are some things that can’t be done with a smart contract.
- You need a backend among other reasons for off-chain or metadata that won’t be stored in the smart contracts.
Have you ever thought about how Moralis works?
Off-chain: Backend infrastructure that collects data from the blockchain, offers an API to clients like web apps and mobile apps, indexes the blockchain, provides real-time alerts, coordinates events that are happening on different chains, handles the user life-cycle and so much more.
Moralis Dapp is used in order to speed up the implementation of the off-chain infrastructure. Moralis Dapp is a bundled solution of all the features most Dapps need in order to get going as soon as possible.
This is a series articles of Blockchain fullstack structure, please read Part 1 Introduction first. In this part, I will show how to set docker to Hardhat, but this is simpler than my previous article Hardhat Solidity NFT tutorial.
Recently, I ogranized a template of my blockchain fullstack project, including a Hardhat Solidity, Golang backend, and React js frontend. Does it need golang backend? Actually, I’m not sure. But there is a post said:
Server:
Even though you have your smart contracts as backend, often times a Dapp will still have an additional traditional server running. Not always, but probably more often than you think.
So, I combined Harhat, Golang gin, and Next.js to my dApp-structure github repo, added some basic, simple interaction from Next.js to Blockchain, and from Golang to Blockchain.
