This version is also compatible with different browsers. You also get defined custom properties for precise control. Removal of Deprecated Properties Tailwind CSS 4.0 removes many deprecated utilities scheduled for deletion. For example, text-opacity-* has been replaced by text-{color}/*. Instead of decoration-slice, the new value is box-decoration-slice. Similarly, flex-grow-* has been replaced by grow-*. The framework has become more straightforward after the removal of these properties. Separation of PostCSS Plugin and CLI Tailwind CSS 4.0 offers the PostCSS plugin and CLI tools separately. They are no longer included in the same package. Therefore, users can install them as needed. Developers have the flexibility to set up projects in their preferred way. They can customize the workflow to meet their project requirements. Field Sizing The field sizing feature will be available soon. However, it will be a significant upgrade in Tailwind 4. With field sizing, developers won’t need JS to make auto-resizing textareas. They will be able to do that simply by using CSS. Rings Are 1px By Default Rings are now preset to 1px. This minor change streamlines the process of adding subtle outlines and focus states. It makes the overall design cleaner and more professional. Final Words These are a few upgrades you get in Tailwind 4.0 Considering everything, Tailwind is a robust CSS framework. Its new features help developers simplify their workflow. Updates like Oxide engine, zero-configuration content detection, and unified tool chain help developers build clean and more accessible web designs with speed.

Top Project Management Techniques to Thrive in Today’s Competitive Era
To a large extent, the success of a project depends on how efficiently you manage it. Project management helps you plan, organize, and manage resources. With efficient management skills, you meet your business goals within a set timeline and budget. This post introduces project management techniques that can be game-changers for your business. If you are starting a new project consider these strategies to gain a competitive edge. Tried and Tested Project Management Techniques PERT (Project Evaluation Review Technique) PERT is a well-known project management technique. It was made by the US Navy in 1950 to manage their Polaris submarine missile program. PERT helps you estimate how long it will take to complete a particular task. You can use it to schedule and coordinate all your project tasks appropriately. How Does PERT Work? The Project Evaluation Review technique uses a flowchart that features nodes, directorial lines, and arrows. Nodes represent events whereas directorial lines highlight jobs that need to be completed. Arrows express the sequences of the activities. In short, the chart outlines the tasks needed for project completion, estimated durations, and dependencies. PERT defines four ways to estimate the time for project completion. Optimistic Time The least amount of time required to complete a job. Pessimistic Time The maximum time it can take to complete a task. Most Likely Time Assuming everything would go well, this is the best estimate of how long the task should take. Expected Time Assuming there may be problems, this is the best estimate of how much time will be needed to complete the task. PERT is an ideal management technique for uncertain projects. Waterfall If you are managing a linear project, the Waterfall technique can be beneficial. This project management method breaks down a project into sequential stages. Team members have to complete one stage before moving to the next. The waterfall method gives a clear picture of the project. It identifies dependencies before the project begins. The stages of the Waterfall method include: Analysis of Project Requirements At this stage, the manager gathers all the information about the project. It helps stakeholders to create a detailed project plan. Designing At this stage, the team outlines the design requirements. If I take the example of a web application, the design requirements could be choosing coding languages, software architecture, and interface. Implementation The team takes action as per the project planning. Verification At this stage, the manager ensures that the project follows the plan. Deployment At this stage, you launch your product to the target audience. Maintenance The maintenance phase involves making an effort to enhance the product’s performance. Kanban The Kanban technique was created by a Toyota engineer to improve the manufacturing process. It is a visual workflow similar to PERT. However, it is set up as a series of task cards. This management technique focuses on working together as a team. The aim is to put less stress on individual members. How Does Kanban Work? The Kanban board tool divides tasks across columns. They represent different stages of the workflow. The Kanban board represents the following three columns: To Do In Progress Done This project management technique helps the manager and team focus on completing tasks by limiting work in progress. The Kanban visual board provides a clear workflow overview, allowing managers to identify bottlenecks and track progress. Critical Path Method (CPM) CPM is a well-known project management method that has been used for decades. The Critical Path shows the shortest time possible for completing a project. Since each task on the critical path is sequential, a delay in any primary task would delay the entire project. Therefore, tasks are marked as Critical and Non-Critical. Critical jobs must be completed on time. Non-critical tasks are less likely to impact the project completion. Managers and team members can be flexible about them. How Does Critical Path Work? The critical path is a visual diagram that shows all task dependencies and their time estimates. This technique is quite helpful in managing projects where time is a priority. You can make a list of all the crucial tasks. Identify those that are dependent on others to be completed. Determine the sequence of tasks and estimate the duration of each task. Depending on the duration of each critical task, you can calculate the overall project timeline. Gantt Chart The Gantt Chart is another renowned method for managing a project. Managers use this chart to figure out their project tasks and their timelines. The chart comprises three components: The project tasks The start date of each task The end date of each task The chart enables you to monitor the progress of your project. It ensures all tasks follow the plan and stays within budget. Final Words These are proven project management techniques to plan, organize, and execute a project. Choose the one that suits the complexity and goals of your project. Are you planning to launch a project and need some consultancy? Contact me. As a technology advisor, I can assess the technology needs of your project and recommend the right project management solutions. I can simplify your project management process by aligning it with the right technology.
The Evolution of Web Development: From HTML to Modern Web Apps
Web development has been evolving continuously since its inception in the early 1990s. From text-based pages to interactive web applications, web development has transformed significantly. This article explores the evolution of web development and highlights the trends shaping its future. Let us begin. The Early Days: HTML and Static Websites The journey of web development began with HTML web pages. These were static, minimally interactive, text-based pages. They served as digital brochures. In the early days of the World Wide Web, developers relied on HTML tags to structure content. They used table-based layouts to design web pages. As the internet expanded, the limitations of HTML-based pages became apparent. Users started desiring more than just static content. This led developers to experiment with new technologies. The Rise of CSS and JavaScript In the mid-1990s, developers began using CSS (Cascading Style Sheets) to style websites. This allowed them to apply different fonts, colors, and layouts to their websites without changing the HTML structure. Around 1996, developers started building visually appealing websites using CSS. During this period, JavaScript also revolutionized web development. JavaScript allowed developers to add animation and interactivity to websites. It would be right to mention that HTML, CSS, and JavaScript together built the foundation of modern web development. Entry of Server-Side Scripting and Databases As websites started becoming complex, developers felt the need for server-side scripting. It was not easy to handle dynamic content with existing web development architecture. The late 1990s witnessed the rise of server-side languages and databases. PHP emerged in the late 90s, alongside Active Server Pages and Java Servlets. During this time, SQL databases like MySQL and PostgreSQL also became popular. They allowed websites to store and retrieve large amounts of data. Introduction of Web Frameworks In the early 2000s, web frameworks like Ruby on Rails and Django were introduced to developers. These frameworks played a crucial role in simplifying backend development by offering structured patterns and minimizing repetitive coding. Ruby on Rails enabled developers to build applications quickly with minimal setup, while Django focused on scalability and security. All in all, both frameworks boosted productivity to a great extent. The Revolution of AJAX AJAX, or Asynchronous JavaScript and XML, came in the early 2000s. It was a revolutionary breakthrough in web development. AJAX allowed websites to fetch and update data asynchronously without reloading the page. This advancement opened the door for modern interactive apps like Gmail and Google Maps. Asynchronous JavaScript and XML is still in use due to its impressive asynchronous communication. Growth of Content Management Systems (CMS) and E-Commerce With the arrival of CMSs like WordPress and Joomla, building websites has become straightforward. Today, these CMSs are accessible to a broader audience. They allow non-technical users to create websites with ease. Platforms like Magento and Shopify have also transformed online shopping by offering advanced e-commerce solutions. They allow users to create and manage online stores. Magento is a scalable platform designed for large enterprises. Shopify, on the other hand, is ideal for small to medium-sized businesses. The Frontend Revolution: JavaScript Frameworks JavaScript frameworks played a primary role in transforming frontend development. Modern web applications are responsive, dynamic, and efficient because of these frameworks. Some notable JavaScript frameworks include: 1.) AngularJS: AngularJS was developed and released by Google in 2010. This robust JavaScript framework introduced two-way data binding. It could streamline complex data interactions and synchronize data between Model & View. 2.) React: React is another renowned JavaScript library developed by Facebook in 2013. Known for its dynamic user interfaces, React introduces a component-based architecture and virtual DOM. It allows developers to create reusable UI components that improve scalability and maintainability. Its virtual DOM updates only the necessary parts of the user interface. Therefore, it supports quick rendering. 3.) Vue.js: Vue.js is a progressive JavaScript framework. Developers use it to build user interfaces and dynamic web apps. Evan You released Vue.js in 2014. It combines the best features of Angular and React. Since Vue.js is lightweight, it loads faster. Moreover, it has a huge community with extensive documentation. Modern Full-Stack Frameworks Modern full-stack frameworks let developers build both the frontend and backend. They are also capable of handling API and Server-side Rendering. Some renowned full-stack frameworks include: 1.) Next.js: This open-source React framework is popular for its static site generation, server-side rendering, and API routes. Developers use it to build dynamic React applications. 2.) Blitz.js: Blitz.js is a full-stack framework for React. It supports built-in data layer integration and follows a convention-over-configuration approach. 3.) Meteor: Meteor.js is an open-source, full-stack JavaScript framework. It lets developers use the same codebase for both the client and server. This isomorphic JavaScript framework keeps client and server data in sync in real-time. Microservices and APIs Today, more and more developers are adopting microservices to manage and scale complex web applications. These services let them break down applications into smaller and independent services. Each service focuses on a particular function and operates on its own. Developers can use microservices to scale applications without affecting the entire system. These individual services communicate through APIs (Application Programming Interfaces). APIs act as messengers, helping microservices send and receive data seamlessly. Conclusion: The Future of Web Development Web development has come a long way since the early days of static HTML pages. In the coming years, numerous new web technologies will emerge. You will see several AI-powered web development tools entering the market. Tools like GitHub Copilot are already helping developers generate code snippets. Additionally, more Progressive Web Apps (PWAs) might emerge that can run without an internet connection. Looking at these trends, it is clear that the future of web development is promising. You can expect continued improvements in user experience and performance.
Feature Prioritization in Product Management: An In-depth Guide
Feature prioritization in product management helps you determine which product feature or functionality your team should work on first. The process aims to avoid useless practices and provide value to customers using limited resources. This post discusses the importance of prioritization for product managers and explores some renowned prioritization frameworks. Let us get started. Why Prioritization is Crucial to Product Managers? The job of a product manager is complex. They play numerous roles altogether. However, they must know where to put maximum effort for making a product successful. Prioritization helps managers focus on the most valuable and impactful features instead of getting stuck on insignificant tasks. Prioritization helps with: Optimization of Resources No matter what product you create, resources are always limited. You can’t spend time, money, and human resources on unimportant things. Prioritization helps managers allocate resources to the most valuable tasks. Focusing on Strategies and Business Goals With a solid prioritization strategy, managers can rest assured that their product development efforts are aligned with your company’s goals. Customer Fulfillment To continuously improve your product, you must prioritize customers’ requirements. Failing to meet customers’ expectations is a sign that you did not address their preferences. Decision Making Individuals with a clear prioritization framework make better decisions. In the current fast-paced business environment, delayed decisions can lead to missed opportunities. Better Productivity Prioritization minimizes confusion significantly. With everything planned, the team works confidently. It naturally boosts motivation and productivity. What to Prioritize? A product management team has to consider various factors throughout the prioritization process. Customers’ Requirements Your first preference should be understanding the pain points of your target audience. Market Demand Analyze market trends and competitors to ensure your product meets current market demand. The Right Allocation of Resources Distribute time, budget, and manpower appropriately to develop the best product. User Experience Assess the influence of your product on users. Get to know if customers are satisfied with the end product. Popular Prioritization Frameworks Product managers use various frameworks to implement feature priority. They provide a systematic approach to assess priorities based on different criteria. These can be value, impact, customer requirement, and more. RICE RICE stands for Reach, Impact, Confidence, and Effort. It is a well-known prioritization framework that helps product managers make informed decisions. Reach It analyzes how many people will benefit from your product within a specific time. Managers measure it in terms of the number of users. Impact Impact measures how a product feature affects the business. It shows to what extent the feature enhances the user experience. You can measure the impact as follows: Massive Impact High Impact Medium Impact Low Impact Minimal Impact Confidence Confidence defines the certainty of your team for Reach, Impact, and Effort. Confidence is scored on a percentage basis. 100% = High confidence 80% = Medium confidence 50% = Low confidence Effort Effort estimates the time and resources needed to implement a feature. You can measure it by analyzing how much work a team member can do in a month. The formula for calculating the score of RICE is: RICE SCORE= REACH X IMPACT X Confidence EFFORT KANO KANO is another renowned framework used by product managers. It prioritizes product features based on how they influence customer satisfaction. Primary components of the KANO Model include: Must-Haves/ Basic Features These are the primary functions of your product. In their absence, the product won’t be valuable to customers. Performance Features The satisfaction of your customers depends on performance features. If you want to improve the performance of your product, work on these features. Delighters These are the features that customers do not expect. However, when delivered, they offer a sense of happiness. Let us understand these feature categories by an example. For instance, features of an E-commerce mobile application can be categorized as below: Basic Features: Secure checkout and easy navigation. Performance Features: Personalized recommendations and quick load time Delighters: Augmented reality feature for trying products virtually. In the KANO framework, managers collect customer inputs through feedback, interviews, and surveys. MOSCOW MOSCOW stands for Must-haves, Should-haves, Could-haves, and Won’t-haves. With this technique, product managers categorize features according to their importance. Must-haves These are the primary features of your product. In their absence, your product will not work. Should-haves These features are important. They improve the value of your product. Could-haves Could-haves are not crucial features. However, if your product includes them, it would be beneficial. Won’t-haves These are features that you do not want to include at present. Opportunity Scoring Framework The opportunity scoring framework also assists managers in prioritizing features. The process involves getting feedback to learn which features are more important to customers. You also get to know how satisfied they are with those features. If customers are not pleased, the team can work on those crucial features. Conclusion Prioritization is a strategy companies use to develop a product that resonates with their target audience and business goals. These are some tried and tested prioritization frameworks. You can choose the one which is relevant to your specific context. If you are struggling to launch a website, application, or IT product, consult with me. As an experienced technology advisory consultant, I can plan strategies to build a successful product. We can work together to assess the priorities of your customers.
JWT vs. PASETO: A Quick Comparison of Two Leading Token-Based Authentication Methods
Token-based authentication has become standard to secure web applications. Unlike conventional authentication systems, it does not store tokens on a server. Therefore, it is less vulnerable to brute-force attacks. JSON Web Token (JWT) and Platform-Agnostic Security and Token (PASETO) are renowned token-based authentication technologies. While both secure the transmission of information between two parties, they differ in their features and functions. This post compares both platforms based on different factors. Read it until the end to learn which one meets your requirements best. What is a JSON Web Token? JWT is an open standard that secures the transmission of information between parties as a JSON object. It verifies user identities and grants access to private resources. JWT consists of three parts: Header The header defines the token type and the signing algorithm. Payload The payload contains statements or claims about an entity (usually the user) and additional data. You can categorize the payload into three types: Reserved claims Public claims Private claims Signature A signature ensures the authenticity of a token. It is created by combining the encoded header, payload, and a secret key. How Does JWT Work? Token Generation Once user authentication is successful, the server produces a JWT. It contains user information and permissions. This token is signed using a key. Token Sent to Client The server sends the JSON web token to the client within the HTTP response header. Storage of Token The client secures the JSON web token in local storage or cookies. Client Request Resource The client adds JWT in the authorization header for future requests to private resources. Server Validates Token The server uses the private key to authorize the JWT’s signature and expiration time. Access Granted/Denied The server grants or denies access to resources based on the token validation. What is PASETO? Designed by Scott Arciszewski, PASETO tokens are platform-agnostic. It means they are not bound to any particular platform or programming language. The token creation is relatively easy with PASETO. Users get only two types of tokens: Local Local tokens are encrypted with the help of a shared secret key stored on a server-side. These tokens make sure that the payload is confidential. Public Public tokens are not encrypted. The payload is visible to the public but protected from tampering. How Does PASETO Work? PASETO eliminates numerous pitfalls of JWT. For example, it has built-in encryption that makes the payload more confidential. Besides this, it employs modern cryptographic algorithms for encryption that are less prone to errors. Let’s compare JWT and PASETO based on different aspects. JWT vs. PASETO Security The level of security in the JSON web token depends on cryptographic algorithms used for signing and encryption. Older versions of JWT are more vulnerable, especially if not implemented properly. PASETO has the upper hand in terms of security. Since PASETO prioritizes security by default, it minimizes the risk of misconfigurations. It uses modern cryptographic algorithms that avoid the drawbacks of previous versions. Additionally, PASETO’s local tokens come with built-in encryption. Flexibility JWT is versatile. It supports different encryption algorithms. Users can employ it for a wide range of applications. JWT is particularly suitable for systems that need integration between services. PASETO is comparatively less flexible. Though its opinionated design makes it more secure, it can be restrictive for users who want more control over token management. Compatibility JWT has been used for quite some time. Consequently, it has received widespread adoption. The technology offers support to various frameworks, libraries, and platforms. It is easy to integrate JWT into existing infrastructure. As PASETO is still new, it does not offer the same level of compatibility as JWT. However, its design principles make it suitable for systems that need high security. Complexity Some developers might find JSON Web Token a little complicated to implement. Choosing an appropriate algorithm and managing key distribution need careful attention. Besides this, JWT does not enforce encryption. Therefore, sensitive information in the payload needs separate encryption. PASETO is simple and secure. It offers a fixed structure with limited cryptographic primitives. There is a negligible chance of security vulnerabilities and implementation errors in PASETO. Use Cases JSON Web Tokens are widely accepted in various libraries. They are more prevalent in existing frameworks and applications. Primarily, developers use them where stateless communication is needed. Some common use cases of JWT include: Authentication API Authentication & Access Control Stateless Sessions Authorization Single Sign-On (SSO) Browser-based authentication, and more. PASETO focuses on modern cryptographic practices. Users prefer it for scenarios where high security is critical. Use cases of PASETO include: Session management in the application API authentication Inter-microservice communication Authorization in distributed systems Stateless authentication in stateless architectures Final Words Both PASETO and JWT are powerful token-based authentication solutions. However, they cater to different priorities. JWT offers more flexibility in terms of compatibility and customizability. On the contrary, PASETO focuses on security by default. It provides strong cryptographic guarantees without requiring you to understand the underlying algorithms. So these are some differences between the two. You can make your choice based on the specific requirements of your application.

Top 10 JavaScript Console Methods for Effective Debugging
JavaScript Console methods are functions provided by JavaScript’s ‘console’ object. These functions enable web developers to access the debugging console in web browsers. In short, they improve the debugging process by letting developers perform different debugging and logging tasks. For instance, they can track the performance of their web codes, output information, and inspect objects and arrays. This post makes you familiar with some crucial JavaScript console methods. Let’s begin. 1. Log Method The console.log() method is one of the primary JavaScript console methods. It allows developers to print numbers, strings, JavaScript variables, or objects in the console. Besides, it logs messages to the debugging terminal rather than displaying them in the browser console. console.log('Hello, world'); console.log({ name: 'Alice', age: 30 }); 2. Info Method The method console.info() is similar to console.log(). It helps developers print information needed for debugging purposes rather than printing values. console.info('This is an informatinal message'); 3. Debug Method The console.log(), console.info(), and console.debug() look similar. Nevertheless, their output visibility in the browser console is different. The browser defines color codes to console method output messages. The output from the console.debug() method does not show in Chrome developer tools by default. Users must enable the console filter option for all levels to see the output from the debug method. console.debug('Debugging message'); 4. Warn Method The console.warn() method allows developers to display a warning message in the console. The message can be anything from an object to an array, to a variable. Generally, warning messages are highlighted with a yellow icon. Therefore, they look different from regular log messages. The message appears in the browser as a warning indicator. console.warn('This is a warning message'); 5. Assert Method The console.assert() method is different from the above-mentioned methods. This console method is used for testing purposes. It evaluates a given expression. If the expression results in ‘false’, it writes an error message to the console.. The console method helps in debugging by verifying certain conditions. console.assert(1 === 2, 'This will fail'); 6. Count Method As the name suggests, the console.count() method is a log counter. It logs the number of times the console.count() method has been called in a script. The console method is useful for tracking how many times a particular code is executed. console.count(label); console.count(label); label (Optional): A string label to identify the count. If there is no label, the default label ‘default’ is used. It’s usage examples are as follow: console.count("myLabel"); // Output: myLabel: 1 console.count("myLabel"); // Output: myLabel: 2 console.count("myLabel"); // Output: myLabel: 3 console.count(); // Output: default: 1 console.count(); // Output: default: 2 In the above example, calling ‘console.count(“myLabel”) three times increments the count for the label “myLabel”. Similarly, calling ‘console.count()’ without a label increments the count for the default label. 7. Trace Method The console.trace() method in JavaScript helps developers output a stack trace to the console. It provides a report of the active stack frames at a particular point in time. The console method shows the path of the execution which led to the current line of code. This debugging purpose helps developers learn how a particular code was reached. Syntax console.trace(label); Label(Optional): A string label appears at the beginning of the stack trace. Example function firstFunction(){ secondFunction(); } function secondFunction(){ thirdFunction(); } function thirdFunction(){ console.trace("Tracking the call stack:"); } firstFunction(); Output Tracking the call stack: at thirdFunction (<anonymous>:10:13) at secondFunction (<anonymous>:10:13) at firstFunction (<anonymous>:10:13) at <anonymous>:14:1 In this example, calling ‘console.trace (“Tracking the call stack:”)’ inside thirdFunction outputs the stack trace to the console, showing the sequence of function calls that led to thirdFunction. 8. Time, TimeLog and TimeEnd Methods The ‘Time’, ‘TimeLog’, and ‘TimeEnd’ are popular JavaScript console methods. Developers use them to measure and log the duration of code execution in programming. Time Method The time method starts the timer and records the time. Developers can calculate the exact duration of a particular operation through this method. TimeLog Method The ‘TimeLog’ method logs the current time along with the elapsed time from the call of the ‘Time’ method. It is quite helpful for recording intermediate steps in a long-running process to learn how long a particular step takes. TimeEnd Method As the name indicates, the ‘TimeEnd’ method stops the timer. It logs the total time since the ‘Time’ method was called. This method gives you a record of the total duration of the operation. console.time('process'); // Start the timer // Code block whose duration you want to measure for (let 1 = 0; i < 1000000; i++) { // Some time-consuming task } console.timeLog('process'); // Log the intermediate time // Another code block for (let i = 0; i <1000000; i++){ // Another time-consuming task } console.timeEnd('process'); // End the timer and log the total time Output process: 10ms process: 15ms process: 20ms 9. Table method The JavaScript ‘console.table()’ method displays tabular data in the console. It is quite useful to visualize an array of objects in an organized way. It helps users understand data in a better way. After all, they can sort columns fast. const data = [ { name: "John", age: 30, city: "New York"}, { name: "Jane", age: 25, city: "San Francisco"}, { name: "Mike", age:32, city: "Chicago"} ]; console.table(data); Output 10. Clear Method The clear method in JavaScript helps developers clear the console. If you want to delete all your previous logs and start fresh, you can use this console command. console.log("This is a log message"); console.log("Another log message"); // Clear the console console.clear(); console.log("This is a log message after clearing the console"); Output This is a log message Another log message This is a log message after clearing the console As soon as the console.clear() is called, the console gets cleared. Only log messages are visible now. Final Words Undoubtedly, there are
Everything You Need to Know About Axios Interceptors
Managing HTTP requests and responses is quite challenging in modern web development. Fortunately, Axios is a robust JavaScript library that simplifies this process by offering a clean API. Axios is a promise-based HTTP client that features a simple intuitive API for sending HTTP requests and handling responses. Interceptors are a primary feature of Axios, helping users modify HTTP requests and responses quickly. This post makes you familiar with Axios interceptors and their roles in web development. So without any further delay, let us get started. What are Axios Interceptors? Axios interceptors are middleware functions that allow you to intercept requests before the primary application logic handles them. These functions are called before a request is sent and after a response is received. They provide a way to control and modify the requests and responses that are sent and received by an application. You can use Axios interceptors to alter requests, manage errors, add headers, and more. We can divide Axios interceptors into two types: Request Interceptors These interceptors are executed before a request is sent. They enable you to change the request configuration or add authentication tokens and headers. Response Interceptors As the name suggests, response interceptors are executed upon receiving a response. They allow you to intercept and handle the response before it gets passed to the calling code. These interceptors are quite useful for managing tasks like data transformation and error handling. How Do Interceptors Improve API Interactions? Interceptors can enhance your API interactions significantly. You can leverage interceptors in the following ways. Centralize Common Functionality With Interceptor, you do not need to repeat the same code across multiple API calls. You can encapsulate shared logic in interceptors. It supports code reusability and maintainability. Improved Security Interceptors help you add authentication headers automatically. Besides this, you can manage token refreshing and implement other security measures. Data Transformation You can transform request and response data before it reaches your application logic. Authentication & Authorization Individuals can also use interceptors to attach authentication tokens to requests. It makes sure that all outgoing requests carry the necessary credentials. If a token expires, the interceptor redirects the user to the login page. Use Cases of Axios Interceptors Adding Authentication Headers Axios interceptors let you inject authentication headers impeccably into outgoing requests. This feature is useful for APIs that need authorization tokens or API keys. import axios from 'axios'; const instance = axios.create({ baseURL: 'https://api.example.com', }); instance.interceptors.request.use(config => { const token = localStorage.getItem('authToken'); if (token) { config.headers.Authorization = `Bearer ${token}`; } return config; }); export default instance; Handling Errors You can also use interceptors to manage errors uniformly throughout your application. Developers can make an error interceptor to find and handle common error responses from the application programming interface. import axios from 'axios'; const instance = axios.create({ baseURL: 'https://api.example.com', }); instance.interceptors.response.use( response => response, error => { if (error.response) { if (error.response.status === 401) { // Redirect to login page } else if (error.response.status === 404) { // Redirect to 404 page } } return Promise.reject(error); } ); export default instance; Refreshing Tokens Interceptors also help in refreshing expired authentication tokens. When an API responds with a 401 status, the interceptor catches this response and sends a request for refreshing the token. axiosInstance.interceptors.response.use( response => response, async error => { if (error.response.status === 401) { const originalRequest = error.config; const refreshToken = localStorage.getItem('refreshToken'); try { const response = await axios.post('/auth/refresh-token', { token: refreshToken }); localStorage.setItem('token', response.data.token); originalRequest.headers.Authorization = `Bearer ${response.data.token}`; return axios(originalRequest); } catch (e) { console.error('Refresh token failed:', e); window.location.href = '/login'; return Promise.reject(e); } } return Promise.reject(error); } ); Loading Indicators & Cancellation Interceptors can take the user experience of your application to the next level. They provide a loading indicator during API requests. Besides this, interceptors let you implement request cancellation to prevent unnecessary network traffic. import axios from 'axios'; const instance = axios.create({ baseURL: 'https://api.example.com', }); let activeRequests = 0; instance.interceptors.request.use(config => { activeRequests++; // Show loading indicator return config; }); instance.interceptors.response.use( response => { activeRequests–; if (activeRequests === 0) { // Hide loading indicator } return response; }, error => { activeRequests–; if (activeRequests === 0) { // Hide loading indicator } return Promise.reject(error); } ); export default instance; Final Words Interceptors in Axios enable developers to intercept and modify HTTP requests and responses. From handling errors to adding headers to managing token expiry, they help you create an efficient and user-friendly application. Using interceptors, web developers can empower their applications to manage network interactions securely and smoothly. Axios interceptors can help whether you want to handle a simple request modification or a complex token refresh mechanism. So if you are a JavaScript developer working on an application that communicates with APIs, leverage the power of Axios interceptors.
