Cache: Caching is a technique used for improving the performance of servers and a lot of devices used in day-to-day life.In caching, the result of certain computation or task is stored somewhere, and if the same computation is required again, it is served from that location itself rather than doing the computation again. This reduces computation and improves performance, thereby providing a better user experience.A lot of apps cache data for the first time they’re fired, hence are able to efficiently provide responses. Similarly, the majority of servers have advanced cached mechanisms for endpoints that serve the same response for the majority of the time....

Django and Node.js are two popular technologies for web development, each with its strengths and best use cases. While Django is a high-level Python web framework, Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine. In this article, we will explore the key differences between Django and Node.js, highlighting their architectures, performance, scalability, use cases, and ecosystems....

The “Cannot GET /” error in Node.js typically occurs when you try to access a route in your web browser that hasn’t been defined in your application. This common issue can be resolved by ensuring that your server is correctly set up to handle incoming requests at the root path or other specified paths....

Express.js  is a powerful framework for node.js. One of the main advantages of this framework is defining different routes or middleware to handle the client’s different incoming requests. Express. js allows us to create multiple routes on a single express server. Creating multiple routes on a single server is better to practice rather than creating single routes for handling different requests made by the client. In this article, we will discuss how to create multiple routes on a single express server....

npm is the default package manager for Node.js, and it is used to install, manage, and distribute JavaScript packages. When you install a package using npm, it can be installed either locally or globally. The location where npm installs the package depends on the installation method you use....

Redux is a state management tool, which is used to store the state of different variables in our react application. It makes complex react applications easier by centralizing the application state. You can learn more about redux here. Redux supports middleware, and middleware functions run between dispatching an action and the moment it reaches the reducer. Redux middlewares can be used for logging, routing, asynchronous actions, etc....

Session management is a crucial aspect of web application development, enabling you to store user data between HTTP requests. In Node.js, session management is often handled using the express-session middleware. This article will guide you through the process of setting up and using session variables in a Node.js application....

NPM stands for Node Package Manager and it is the package manager for the Node JavaScript platform. It put modules in place so that node can find them, and manages dependency conflicts intelligently. Most commonly, it is used to publish, discover, install, and develop node programs....

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. The cors package available in the npm registry is used to tackle CORS errors in a Node.js application....

Calling an API endpoint is the core functionality of modern internet technology. Usually, we call API from the browser. Sometimes we need to call API endpoint from the server itself to fetch data, load dependencies, etc....

HTTP and Express both are used in NodeJS for development. In this article, we’ll go through HTTP and express modules separately...

The Zip files are a common way of storing compressed files and folders. In this article, I’ll demonstrate how to convert the file to zip format by using the adm-zip module (NPM PACKAGE)....
