Mongoose serves as a powerful abstraction layer between Nodejs applications and MongoDB, providing schema validation, middleware hooks and elegant query building.
Real world applications often require coordinating multiple related operations that must either all succeed or all fail together.
In the world of JavaScript development, understanding how objects behave in memory can be the difference between a lightning fast application and one that crawls to a halt. Every time you create an object, array, or function in JavaScript, you’re working with a JS Object; the fundamental building block that powers the entire language.
API documentation is crucial for any backend service, and Swagger/OpenAPI has become the de facto standard for documenting REST APIs. However, maintaining documentation manually can be time-consuming and error-prone. This guide explores how to automatically generate Swagger documentation from Joi validation schemas using the joi-to-swagger library, ensuring your API documentation stays in sync with your validation logic.
In the world of database optimization, indexes are like a double-edged sword. While they can dramatically improve query performance, having too many indexes can actually harm your database’s overall efficiency. This guide will walk you through the process of identifying and removing unnecessary indexes in MongoDB, using a real-world example to illustrate the concepts.
In the world of functional programming, techniques that enhance code reusability and modularity are highly valued. One such technique that has found its way into JavaScript is currying. But what exactly is currying, and is it really just a chain of functions?
