Node.js Development with `nodemon and node –trace-warnings`

Node.js remains a popular choice for developing server-side applications due to its efficiency and scalability. In this ecosystem, tools like node –trace-warnings and nodemon can significantly enhance the development workflow. Each serves a unique purpose: node –trace-warnings helps in debugging and maintaining code by providing detailed information about warnings, while nodemon boosts productivity by automatically… Read more Node.js Development with `nodemon and node –trace-warnings`

Mongoose Schemas and Their Role in MongoDB Collections

If you’re new to back-end development or just starting to explore NoSQL databases, you might find the concept of schemas a bit perplexing, especially when coming from a NoSQL database like MongoDB which is inherently schema-less. This is where Mongoose, a powerful Object Data Modeling (ODM) library for MongoDB and Node.js, comes into play. It… Read more Mongoose Schemas and Their Role in MongoDB Collections

Efficiently Managing MongoDB Connections in Multi-Database Environments

In the world of database management, particularly with MongoDB, developers often encounter scenarios where multiple databases are used within the same application. Each database may serve different parts of the application, or perhaps, different applications altogether. However, managing connections and authentication across these can seem daunting at first. In this blog post, we’ll explore how… Read more Efficiently Managing MongoDB Connections in Multi-Database Environments

Embracing the Power of Microservices with Node.js

Introduction to Microservices and Node.js In today’s fast-paced digital world, the need for scalable, efficient, and reliable web applications is more crucial than ever. This is where the concept of microservices comes into play, especially when combined with the robustness of Node.js. Microservices represent a shift from traditional monolithic architecture to a more modular approach,… Read more Embracing the Power of Microservices with Node.js

Error First Callbacks in Node JS

Callbacks are a systemic part of a Node.js application. A non-blocking well-balanced flow of controlled asynchronous modules is made possible by properly implemented callbacks. But what is “properly implemented”? Creating code that will scale with your projects means using a reliable protocol that is a well-known standard. The “error-first” callback (also known as an “error-back”,… Read more Error First Callbacks in Node JS

Iterate an array with a promise in javascript

Example of how to iterate an array with a promise It can be challenging to figure out how to iterate over an array of items with a promise. The following code takes a callback function that may or may not be a promise already.
