The asynchronous function can be written in Node.js using ‘async’ preceding the function name. The asynchronous function returns an implicit Promise as a result. The async function helps to write promise-based code asynchronously via the event loop. Async functions will always return a value. Await function can be used inside the asynchronous function to wait for the promise. This forces the code to wait until the promise returns a result....
Node.js is a JavaScript-based platform mainly used to create I/O-intensive web applications such as chat apps, multimedia streaming sites, etc. It is built on Google Chrome’s V8 JavaScript engine....
Welcome to the world of Node.js, an open-source runtime environment that has transformed the landscape of backend development. Traditionally, JavaScript was confined for frontend development, powering user interactions on the browser. However, with the advent of Node.js, JavaScript has broken free from these chains and now reigns on the server-side as well, enabling full-stack development with a single language. Node.js runs on chrome v8 engine which converts javascript code into machine code, it is highly scalable, lightweight, fast, and data-intensive....
The word CORS stands for “Cross-Origin Resource Sharing”. Cross-Origin Resource Sharing is an HTTP-header based mechanism implemented by the browser which allows a server or an API(Application Programming Interface) to indicate any origins (different in terms of protocol, hostname, or port) other than its origin from which the unknown origin gets permission to access and load resources....
JSON Web Tokens (JWTs) are widely used for authentication and authorization in modern web applications and APIs. One crucial aspect of JWTs is their validity period, which determines how long a token remains valid after it has been issued. In this article, we’ll delve into the factors influencing the validity period of JWT tokens and best practices for setting their expiration time....
Mongoose is an Object Data Modeling (ODM) library for MongoDB. It defines a strongly-typed-schema, with default values and schema validations which are later mapped to a MongoDB document....
REST (Representational State Transfer) is an architectural style for designing networked applications. A RESTful API is an API that adheres to the principles of REST, making it easy to interact with and understand. In this article, we’ll explore what REST API is in the context of Node.js, its principles, and how to create one....
Taking input in a Node.js application is essential for building interactive command-line interfaces, processing user input, and creating dynamic applications. Node.js provides several methods for receiving input from users, including reading from standard input (stdin), command-line arguments, and user prompts. This article will cover various techniques for taking input in Node.js, along with examples and best practices....
Implementing pagination in a Node.js application involves fetching and displaying data in chunks or pages, typically from a database. One common approach to pagination is using sorting IDs, where each record in the dataset is assigned a unique identifier (ID) that determines its position in the sorted sequence. This method allows you to efficiently retrieve data based on these IDs to implement pagination. Let’s dive into how you can achieve pagination using sorting IDs in a Node.js application....
In this article, we are learning about how can we send data to a node server using Ajax without reloading the page from the client-side....
This Article speaks about setting up your node.js server for verifying emails via OTP....
In node, Load balancing is a technique used to distribute incoming network traffic across multiple servers to ensure no single server becomes overwhelmed, thus improving responsiveness and availability. In this article, we’ll explore how to create a load-balancing server using Node.js....
