Photo by Denys Nevozhai on Unsplash As we build interactive web applications using React and React Router, security becomes a crucial aspect to consider.It is essential to ensure that only authorized users can access sensitive information by protecting certain routes.While there are various mechanisms such as access tokens or role management libraries to implement a comprehensive authentication system, in this tutorial, we will focus on implementing route access validation using React Router.

Before you dive into the blog, let me brief you about client and server-side routing.Client-side routing and server-side routing are two different approaches to handling navigation within web applications.Here's a brief explanation of the differences:
Client-side routing: In client-side routing, the routing logic is handled on the client side (in the browser).

In React, optimizing performance is a crucial aspect of building high-performing web applications.One powerful tool in a React developer's arsenal is the useMemo hook.This hook allows for the memoization of expensive computations, resulting in improved performance and responsiveness.In this article, we will explore the useMemo hook in detail, understand its purpose, and examine real-time examples to demonstrate its effectiveness.

There are more than 1.3 million libraries available in the NPM registry.We don't have to start from scratch.Just install the right library, and it's a piece of cake.Have you ever wondered how these libraries are installed and managed in projects?When you install a library from npm in Node.js, npm will download the package and its dependencies and store them in a local node_modules directory in your project.

You might have definitely come across this package-lock.jsonfile if you are working on projects where Node.js is used.In this article, we will see what is package-lock.jsonfile, why it is required, and how it is different from the package.jsonfile.What is a package.jsonfile?It is a JSON file that is present in the root directory of the project and it holds important information about the project, it basically contains the metadata about the project and all the dependencies that were installed using NPM.

Serverless applications are critical for cloud-native customers, and gaining visibility into their functions can take time and effort.This blog post will offer tips and code examples for Amazon Web Services (AWS) engineers to help set up serverless monitoring easier with New Relic.The example three-tiered application includes API Gateway, Lambda, and Amazon Relational Database Service (RDS).

Kubernetes is a powerful platform that helps you manage your containerized applications by automating many of the tasks involved in running them.It acts like a personal assistant, taking care of all the nitty-gritty details so you can focus on the bigger picture of your applications.For example, Kubernetes can automatically scale your application up or down based on demand, handle load balancing between different parts of your application, and ensure that your application is always available, even if some of the servers in your cluster go down.

In this tutorial I will walk you through how to build a Boto3 environment using Docker.We will use the official image of Ubuntu on Dockerhub, download three repos to the local host, create three containers with a bind mount to one of the repo directories, then log into each container and verify access to each repo directory.

Some key lessons I've taken away over the years are:
1.The Spec is only as good as the discipline of the person/group of individuals enforcing it.

In episode 526 of the Changelog podcast entitled, "Git with your friends", they discussed various tools involving git (disclaimer: I have been on the podcast multiple times and had dinner with the hosts of the podcast the last time they were in Vancouver).Two the projects they discussed happened to be written in Python.

As part of one of the job applications I have going I was invited to do a frontend expertise exercise.The role I am applying for is head of frontend for a company.Whilst I found it odd to have to go through this, with my track record being highly visible, I thought, why not?After all it feels sensible to make everyone do the same work to get a job, should you want to compare directly.

By now we have the app working, but let's just pretend this is version 0.1 and we want to evolve it as part of a team.That means we'll need a way to share the code, let others collaborate with it and most likely, version each component individually in case you'd also like to re-use them somewhere else.

I think I have written articles about the problem of writing unit tests for UI components.Here're a few articles that I wrote that lead to the conclusion of this article here:
So the main issue can be demonstrated via the following component snippet:
In a unit test, we want to check the return elements from the render of the component; however, there are too many hidden dependencies we don't see from the explicit interface of App function, including:

(1) global dom-related dependencies
(2) API-related dependencies
(3) framework wise dependencies


Believe it or not, most of us can figure out one or two of the above hidden dependencies, but not all of them.

1. UX tasks should be integrated into the product development process to ensure their successful implementation and user satisfaction.

Testing is an integral part of software engineering.For beginners, writing a test case makes sure that your code does exactly what you expect it to do.Every programming language has various frameworks that help you test your code.Small pet projects can get away with not having testing in place, but as an application scales, you run into the risk of hitting a wall where you become paranoid after you push a new feature to production.

AWS Lambda is an excellent service for developing serverless applications.It enables developers to create functions that can be triggered by a variety of events without the need for server management.You can use middleware to handle common tasks like input validation, error handling, and response formatting to streamline and modularize your Lambda functions.

In the Brezhnev era of Vladimir Putin's youth, May 9 was an occasion for Soviet militarism, a celebration of weapons and might.It could be forgotten, at least for a moment, that Leonid Brezhnev's war of choice would be fought and lost in Afghanistan less than two decades after he began the May 9 celebrations, much as what is likely Mr. Putin's last war is today being fought and lost in Ukraine.

Modern web application architectures are built with loosely coupled components.It helps to keep the architecture lean and flexible.However, we still have to deal with existing applications that are yet to adopt these architectural styles.This article will take you through transitioning a full-stack web application into independent component architecture as follows.

React, a popular JavaScript library for building user interfaces, was developed by Facebook in 2013.With its declarative nature and component-based architecture, React enables developers to create scalable, fast, and maintainable applications.It is used for building complex applications, such as web apps, mobile apps, and even virtual reality experiences.

The @state-less/clean-starter repository is designed to provide a starting point for developers exploring React Server.It includes essential backend components, utilities, and examples that illustrate the fundamental concepts and capabilities of React Server.React Server allows the creation of server-side React components using TSX, promoting a component-driven architecture for building robust and maintainable backend solutions.

In the UI/UX field, adding icons helps create a visual indicator for a particular element (i.e., a button, or a tab header) to express the context/action without so much text.Moreover, adding icons makes the app eye-catching and friendly for users.We can add icons to our Vue.jsapps with various icon libraries that come with either font- or SVG-based icon sets.
