Web Apps

A web App (web application) is an application program that is stored on a remote server and delivered over the internet through a browser interface. There is a wide range of technology that can be used in web apps, this session focuses on web app development for blockchain only, let’s explore the top frameworks and libraries.

As the global adoption of blockchain technology accelerates, businesses across industries are increasingly seeking to adopt decentralized solutions for various applications. This demand has spurred the growth of web app development services that focus on blockchain technologies. In this article, we will explore the various web app technologies and frameworks, such as React JS, Angular, and Vue JS, as well as common crypto libraries like Crypto-js, Ethers.js, WalletConnect, and Web3.js.

Web Frameworks

React JS

React JS is an open-source JavaScript library developed by Facebook that allows developers to build fast and scalable user interfaces. It uses a virtual DOM to optimize rendering performance and enables the creation of reusable UI components. React is particularly well-suited for building single-page applications (SPAs) that interact with blockchain networks due to its ability to efficiently handle data-heavy applications.

Some popular blockchain projects built with React include Augur, a decentralized prediction market platform, and Gnosis, a platform for decentralized applications and prediction markets.

Angular

Angular is a popular web app development framework developed and maintained by Google. It is a complete solution for building dynamic, single-page applications and is particularly well-suited for large-scale projects, thanks to its strong focus on maintainability, testability, and modularity. Angular uses a component-based architecture and supports two-way data binding, making it an excellent choice for building blockchain applications that require real-time updates and data synchronization.

Some notable blockchain projects built with Angular include Aragon, a platform for creating decentralized organizations, and Kyber Network, a decentralized cryptocurrency exchange.

Vue JS

Vue JS is a progressive JavaScript framework for building user interfaces. It is designed to be incrementally adoptable, allowing developers to easily integrate Vue into their projects and scale as needed. Vue's core library focuses on the view layer only, making it easy to pick up and integrate with other libraries or existing projects.

Vue's flexibility and simplicity make it an excellent choice for blockchain projects looking for a lightweight and easy-to-learn framework. Notable blockchain projects built with Vue include MyEtherWallet, a popular Ethereum wallet interface, and CryptoKitties, a blockchain-based virtual game.

Crypto Libraries

Integrating with blockchain networks requires specialized libraries for handling cryptographic operations and communicating with blockchain nodes. Some common crypto libraries for web app development include:

Crypto-js

Crypto-js is a popular JavaScript library for performing cryptographic operations, such as hashing, HMAC, and encryption. It supports various algorithms like SHA-256, RIPEMD-160, AES, and more. Crypto-js is widely used in blockchain projects to handle data encryption and secure communications between clients and nodes.

Ethers.js

Ethers.js is a lightweight JavaScript library for interacting with the Ethereum blockchain. It provides a simple interface for connecting to Ethereum nodes, sending transactions, and interacting with smart contracts. Ethers.js is designed to be easy to use and understand, making it a popular choice for both beginners and experienced developers.

WalletConnect

WalletConnect is an open-source protocol for connecting web-based decentralized applications (dApps) to mobile wallets. It enables users to interact with dApps using their mobile wallet without exposing their private keys, ensuring a secure and user-friendly experience. WalletConnect is widely used in the blockchain ecosystem and is supported by many popular wallets, such as MetaMask, Trust Wallet, and Argent.

Web3.js

Web3.js is the official JavaScript library for interacting with the Ethereum blockchain. It provides a comprehensive API for connecting to Ethereum nodes, sending transactions, managing accounts, and interacting with smart contracts. Web3.js is essential for any Ethereum-based web app development and is widely used by the blockchain community.

The web technologies for blockchain are huge and a successful decentralized web app will require a combination of many powerful frameworks and libraries. Web3Hub’s engineering team has extensive experience working with all of the popular technologies that makes any application successful.
