Dynamic Imports in Nextjs

Next.js supports dynamic import(), which allows you to import JavaScript modules (including React components) dynamically.  Each dynamic import is loaded as a separate chunk, enabling component-level code splitting.  By using dynamic imports, you can control resource loading so that users only download the code they need for the part of the site they’re currently viewing1. … Continue reading Dynamic Imports in Nextjs

Error Handling in Nextjs

Error handling in Next.js ensures graceful responses to unexpected issues. Utilize try-catch blocks, ErrorBoundary component, and onError method to catch and handle errors. Implement custom error pages for a polished user experience. Try-Catch Blocks: Wrap critical code segments in try-catch blocks to capture synchronous errors. This approach helps prevent application crashes and allows for graceful… Continue reading Error Handling in Nextjs

Encryption and Decryption of passwords from the frontend(Next JS)

There is a possibility to use the common js file for encrypting the passwords. For the same function, we can use the entire module of the javascript below.  XORCipher.js const XORCipher = {     encode: function encode(key, data) {         data = this.xor_encrypt(key, data);         return this.b64_encode(data);  … Continue reading Encryption and Decryption of passwords from the frontend(Next JS)

escape() and unescape() for error when missing ‘)’ response of the API

Certainly! When handling responses from APIs that may contain characters needing escape, like parentheses, you can utilize escape() and unescape() functions in JavaScript to manage them gracefully. escape() function converts special characters, such as parentheses, into hexadecimal escape sequences, ensuring their proper representation in strings. Conversely, unescape() decodes such sequences back to their original characters,… Continue reading escape() and unescape() for error when missing ‘)’ response of the API

Configuring values in Next.js using next.config.js

Configuring values in Next.js next.config.js involves exporting a JavaScript object with specific configuration options. Here’s a basic example of how you can configure values: Create a file named next.config.js in the root directory of your Next.js project if it doesn’t already exist. Inside next.config.js, export an object with the configuration options you want to set.… Continue reading Configuring values in Next.js using next.config.js

Middleware in Next.js

What Is Middleware? Middleware is a piece of code that runs before a request is completed. It acts as a bridge between the incoming request and your application. By leveraging middleware, you gain flexibility and control over how requests are handled and responses are modified. Use Cases for Middleware: Authentication and Authorization: Middleware ensures user identity… Continue reading Middleware in Next.js

useSelectedLayoutSegments in Next.js

useSelectedLayoutSegments is a Client Component hook that lets you read the active route segments below the Layout it is called from. It is useful for creating UI in parent Layouts that need knowledge of active child segments such as breadcrumbs. ‘use client’   import { useSelectedLayoutSegments } from ‘next/navigation’   export default function ExampleClientComponent() {… Continue reading useSelectedLayoutSegments in Next.js

Difference between parseISO(string) and new Date(string)?

The difference lies in the way they handle parsing of date strings and in their behavior regarding the interpretation of time zones. parseISO(string): This function is typically used in libraries like date-fns for parsing ISO 8601 formatted strings into JavaScript Date objects. ISO 8601 format includes the date and time in a standardized format. parseISO… Continue reading Difference between parseISO(string) and new Date(string)?
