Beginner’s Guide to Become a Web3 Developer

Beginner’s guide to becoming a web3 developer: A primer on backend and the frontend web3 development

Web3 development has several components. As with Web2, the primary components are the front-end and back-end. Furthermore, because smart contracts are an important component of dApps, they merit their own category. Of course, there is the establishment and growth of new programmable blockchains.

This involves understanding which tools to use and which languages to acquire for Web3 development. Furthermore, you should concentrate on providing tangible results that you can demonstrate to your colleagues, prospective clients, or investors. As a result, you must discover how to build an excellent dApp UI, an interface that is clearly critical. On the other hand, you can’t implement good functionalities without a suitable backend and smart contracts.

Blockchain Fundamentals: Blockchain is the first concept you must grasp in order to become a web3 coder. This will allow you to quickly design and optimize smart contracts. Let’s go over what blockchain is and how it functions.

Blockchains are installed on computers called nodes all over the globe. As a result, you’ll need to reach the majority of computers and repeat the procedure. It’s nearly impossible for a machine to do all of this quickly enough for the network to detect and kick the fraudster off the blockchain.

Decentralized Applications: DApps, or Decentralized Applications, are blockchain-based applications.

Frontend: JavaScript frameworks like React, Vue, Angular

Backend: Rust and Solana or Solidity and Ethereum

Frontend Site Programming Fundamentals: The backbone of DApps may be powered by blockchain technology, but the interface is written in JavaScript.HTML — Common HTML tags.

The front end is written in JavaScript

CSS — Basic Properties, Flex, Grid

CSS Frameworks [Optional] — Bootstrap, Semantic UI, Tailwind, etc

JavaScript — Variables, Functions, Classes, ES6, etc.

JavaScript Frameworks

Backend web2, as a backup in case web3 fails. Here is what you should know about the backend:

NodeJS — Event loop, I/O

API Architecture — Express

 Databases — MongoDB, SQL, PostgreSQL

Ethereum Fundamentals: Ethereum is a network that is used to execute smart contracts. In 2022, Ethereum will be by far the most common blockchain for making smart contracts. Solidity is the language used to create smart contracts.
smart contracts: Smart contracts are arrangements that are executed by immutable code on the network. Smart contracts are comparable to JS classes. DApps are powered by these. Solidity is a high-level, object-oriented computer language designed especially for creating smart contracts. Because solidity is so novel, there are few tools for learning it. The best method to learn is to create projects and solve issues by consulting documentation. Consider some resources that follow a comparable strategy.

Build space: Build space is a cohort-based learning tool that is an excellent resource for studying Web3. Solana, Polygon, and Ethereum can be used to create DApps, NFT collections, NFT web games, DAOs, and much more.
LearnWeb3DAO: Web3 DAO is yet another fantastic Web3 utility. It has four distinct tracks for developers of varying ability levels: Freshman, Sophomore, Junior, and Senior. You will learn how to create DApps, NFT collections, ICO coins, DAOs, DeFi networks, and many other things.
Crypto Zombies: CrytoZombies is a gamified programming training in which you use smart contracts to construct an undead factory.

Connect Your Smart Contract with Your Frontend: Now that you understand how to create smart contracts, you must put them to use. There are two primary tools for doing this: web3.js and ethers.js. Let’s look at why ethers.js is superior to web3.

Much smaller size
Less buggy
Better documentation
More Popular
Easier for beginners
Extra Features

Alchemy: Alchemy is a set of developer tools for prototyping, debugging, and shipping products more quickly. Alchemy uses a variety of networks, including Ethereum, Polygon, Stark net, Flow, and others. It has an excellent NFT API that enables you to quickly get your NFT collection up and going. It also has a supercharged cryptocurrency API and supports web 3.0 push alerts.
Remix: Remix is a browser-based Editor designed especially for creating Ethereum smart contracts with Solidity. There is no need for preparation; you can begin writing code right away. It generates your code and allows you to quickly test it. Not only that but your smart contract can be simply deployed.
Hardhat: Hardhat makes it simple to publish contracts, perform tests, and debug Solidity code. You can launch your contract on a variety of networks, including Ropsten, Rinkeby, and Mainnet. Yes, and it supports TypeScript as well.
Truffle: Truffle is my preferred smart contract creation tool. It allows you to quickly build and use smart contracts in your front-end code. Ganache also includes Truffle, which mimics a blockchain and adds test accounts, among other things. It’s extremely beneficial to prevent jargon.
