Node.js developers often reach for Promise.all() when handling multiple asynchronous operations. However, this seemingly innocent approach can cause serious performance issues in production environments. Understanding the limitations of Promise.all() and implementing proper batch execution strategies is crucial for building robust, scalable Node.js applications.
Middleware is the hidden plumbing of a Nodejs and Expressjs application. It sits between the incoming request and the final route handler, letting you validate, transform, log, secure, or reject traffic before it ever reaches your business logic. When written well, middleware keeps your codebase modular, testable, and easy to reason about.
In JavaScript, you can use dot notation (.) or bracket notation ([]) to access object properties. They do the same thing… until they don’t. Then you’ll be googling “why is JavaScript like this”!
Mongoose plugins are powerful tools that can extend the functionality of your MongoDB schemas, simplifying complex tasks and promoting code reuse. Read our previous blog Mongoose Plugins Made Simple: A Beginner Friendly Guide However, even experienced developers can encounter common pitfalls that lead to bugs, performance issues, or unexpected behavior. In this guide, we’ll explore frequent mistakes made when using Mongoose plugins and provide practical solutions to help you write more robust, efficient, and maintainable applications. Understanding these pitfalls will save you valuable time debugging and ensure your plugins work seamlessly together.
Mongoose plugins are like add-ons for your database models. They let you reuse features (like timestamps, soft deletes or validation) across different parts of your app, so you don’t have to write the same code over and over. They also promote code reusability, simplicity and maintaining consistency across your application. This guide will show you, step by step, how to use and create Mongoose plugins; even if you are new to Mongoose or MongoDB.
