Automating your deployment process is essential for a smooth workflow, especially when working with Firebase Hosting. This guide will walk you through setting up Continuous Integration (CI) to ensure your changes are tested and deployed automatically.

Mongoose pre hooks are middleware functions that run before certain operations, such as saving or validating a document. They are useful for a variety of tasks, including data validation, transformation, and managing related data.

Why Use Pre Hooks?​

Pre hooks allow you to:

• Validate or sanitize data before it’s saved to the database.
• Automatically perform actions like hashing passwords.
• Clean up related data before deletion.
• Modify queries before executing them.

This article provides a comprehensive guide on naming conventions for various components in Node.js backend development, including controllers, models, routes, services, middlewares, utilities, configuration files, tests, and environment variables. It emphasizes the importance of consistent naming practices for enhancing code readability and maintainability. The article includes clear examples and explanations for each category, illustrating best practices for file naming, class and function naming, and directory structure. By following these conventions, developers can create well-organized, collaborative, and easily navigable Node.js applications.

Naming Conventions in Node.js Backend Development​

Consistent naming conventions in a Node.js application promote clarity, maintainability, and collaboration among developers. Here's a breakdown of common practices for different components:

What is useEffect in React?​

useEffect is a React hook that allows you to perform side effects in functional components. Side effects refer to operations that interact with the outside world, such as:

• Data fetching: Making API calls to retrieve data.
• Subscriptions: Listening for events (e.g., from WebSockets).
• Direct DOM manipulations: Changing the document title or manipulating third-party libraries that interact with the DOM.
• Timers: Setting up intervals or timeouts.

The rise of decentralized finance (DeFi) and blockchain technology has ushered in a wave of tokens, with ERC-20 tokens at the forefront on the Ethereum blockchain. This article explores what ERC-20 tokens are, their significance, and the process of developing your own token on both Ethereum and Polygon.

Node.js is a powerful, event-driven runtime environment built on Chrome's V8 JavaScript engine. One of its core components is the EventEmitter class, which is fundamental to how Node.js applications handle asynchronous events. In this article, we'll delve into what the EventEmitter is, its advantages and disadvantages, and provide a real-world example of how to use it.

What is EventEmitter?​

The EventEmitter class is part of the Node.js events module and provides a way to handle asynchronous events. It allows objects to emit events and other objects to listen for those events and execute callbacks when they occur. This pattern is essential for building non-blocking, event-driven applications.
