The Benefits of Using RTK Query: A Scalable and Efficient Solution
Wed, 12 Jun 2024

As developers, we're constantly seeking ways to streamline our workflows and enhance the performance of our applications. One tool that has gained significant traction in the React ecosystem is Redux Toolkit Query (RTK Query). This library, built on top of Redux Toolkit, provides a solution for managing asynchronous data fetching and caching. In this article, we'll explore the key benefits of using RTK Query.

The Benefits of Using RTK Query: A Scalable and Efficient Solution

1. Simplicity and Ease of Use

One of the most compelling advantages of RTK Query is its simplicity. This is how one would easily define endpoints for various operations, such as querying data, and creating, updating, and deleting resources. The injectEndpoints method allows you to define these endpoints in a concise and declarative manner, reducing boilerplate code and improving readability.

JavaScript, Node.js, and Apache Kafka for Full-Stack Data Streaming
Mon, 10 Jun 2024

JavaScript is a pivotal technology for web applications. With the emergence of Node.js, JavaScript became relevant for both client-side and server-side development, enabling a full-stack development approach with a single programming language. Both Node.js and Apache Kafka are built around event-driven architectures, making them naturally compatible for real-time data streaming. This blog post explores open-source JavaScript clients for Apache Kafka and discusses the trade-offs and limitations of JavaScript Kafka producers and consumers compared to stream processing technologies such as Kafka Streams or Apache Flink.

JavaScript: A Pivotal Technology for Web Applications

JavaScript is a pivotal technology for web applications, serving as the backbone of interactive and dynamic web experiences. Here are several reasons JavaScript is essential for web applications:

GenAI-Powered Automation and Angular
Thu, 06 Jun 2024

Building a full-featured Angular browser/mobile user interface requires a very specific skill set. There is a vast array of tools, frameworks, and platforms, and each requires a steep learning curve.

An open-source project, ApiLogicServer, has released a technical preview that combines GenAI-powered microservice automation with Ontimize, an Angular UI framework. While the promise of a complete running application is the goal of GenAI-enabled microservice, the developer will still need to interact with the generated components to create a finished web application.  

Mocking Dependencies and AI Is the Next Frontier in Vue.js Testing
Thu, 06 Jun 2024

Vue.js is a popular JavaScript framework, and as such, it is crucial to ensure that its components work as they are supposed to: effectively, and more importantly, reliably. Mocking dependencies is one of the most efficient methods of testing, as we will discover in this article. 

The Need for Mocking Dependencies

Mocking dependencies is a way of exerting control over tests by providing the capacity to isolate components under test from their dependencies. As all frameworks work with multiple components, which can range from APIs to services and even interactions such as clicks or hovers, it is important to be able to isolate these components to test for their durability, behavior, and reliability. Mocking dependencies allow users to create a controlled testing environment to verify the component's behavior in isolation.

How to Effortlessly Host Your Angular Website on GitHub Pages
Thu, 06 Jun 2024

Angular is a leading framework for building web applications and a large number of companies use it in their enterprise software building. This makes the ability to showcase your Angular application quite lucrative. It is not always straightforward though to showcase your Angular skills to others. Maybe you work for an application that is internal to your company only, or it is behind a pay subscription or you are an aspiring student who has not yet worked on a real-world application. 

It can be very costly to host your sample web application on online cloud hosting platforms or can become hard to maintain if you decide to host it on your local machine. GitHub pages offer a very cost-effective way to host, and with Angular’s GitHub page integration, it becomes a breeze to host your app. 

How To Perform Data Migration in MongoDB Using Node.js
Wed, 05 Jun 2024

Data migration in MongoDB refers to the process of transferring data from one database to another. This could involve moving data between different MongoDB instances, upgrading to a newer version of MongoDB, or restructuring the database schema.

Data migration is crucial for maintaining database integrity and scalability. It ensures that data remains accessible and usable as the database evolves. Without proper migration processes in place, data may become fragmented, outdated, or inaccessible, leading to issues with data quality and system performance. Therefore, understanding how to perform data migration effectively is essential for developers working with MongoDB.

How To Optimize AG Grid Performance With React
Fri, 31 May 2024

AG Grid is a feature-rich JavaScript library primarily used to build robust data tables in web applications. It’s used by almost 90% of Fortune 500 companies and it’s especially useful in Business Intelligence (BI) applications and FinTech applications.

React is the market leader of JavaScript libraries to build enterprise web and mobile applications. It is widely adopted by major companies and boasts a large community.

Angular vs. React: In-Depth Comparison
Mon, 27 May 2024

The state of JS 2022 survey shows that, while over the last few years, many new frameworks have emerged, React and Angular still reign supreme.

Front-end frameworks usage ratio over time. Source: State of JS 2022

The former’s position seems quite clear – while React’s usage ratio has been steadily climbing, its competitors are rising and falling. Even Angular, React’s “archnemesis,” which has been developed for almost 3 years longer, is falling out of fashion (and quite fast, to be honest — it lost 5% of its usage ratio in 2022). 

How To Protect Node.js Form Uploads With a Deterministic Threat Detection API
Fri, 24 May 2024

It’s increasingly common to see web applications incorporate custom file upload forms, and popular runtime environments like Node.js have played a noteworthy role in making this possible. This has, in turn, converted form upload entry points into a burgeoning attack vector, as threat actors are now incentivized to exploit insecure form uploads in targeted attacks using specially crafted malicious files.  

In this article, we’ll briefly examine why the popularity of custom form upload handlers has increased in recent years, and we’ll subsequently look at a deterministic threat detection API that can help protect a Node.js form upload application.

Enhancing Angular Directives: Implementing Permission-Based Conditional Rendering With Else Case
Fri, 24 May 2024

Controlling access to parts of a user interface based on user permissions is essential in modern web applications. Angular provides a robust framework for creating reusable and dynamic components, but it does not offer built-in support for conditional rendering with an else case based on user permissions. In this article, we will walk through the creation of a custom Angular directive that handles permission checks and supports an else case, allowing for cleaner and more maintainable code.

Use Cases

Role-Based Access Control

Many applications have different roles with varying levels of permissions. With our custom directive, you can easily control access to certain features or components based on the user's role.
