Growing Pains: How Dynamic Arrays Handle New Elements ?

Dynamic Arrays are resizable arrays that can automatically adjust their size when elements are added or removed.
Dynamic Arrays are built on top of Static Arrays.
When a new element is added, a new array is created with double or greater capacity.
Understanding the mechanics of dynamic arrays is crucial for efficient programming.

Micro Frontends: Module Federation vs. Ripple CI

Micro frontends have emerged to make building scalable web applications easier. To do this, monolithic frontends are broken down into smaller, independent pieces that teams can work autonomously on.
This makes it possible to deliver features faster, but integrating the independent pieces can bring a few unique challenges when creating the final application.
Two possible solutions are Module Federation and Ripple CI, which offer solutions for balancing the need for runtime flexibility with build-time stability.
Module Federation resolves the challenge of runtime integration for microfrontends and allows for faster iterations by deploying updates independently.
Challenges with Module Federation may include increased runtime complexity and performance overheads and maintenance issues. Composable Module Federation can help address some of these challenges and ensure scalability, collaboration and consistency.
A recommended solution is Ripple CI, ensuring build-time stability in Component-Driven Micro Frontends. Ripple CI is a component-driven CI/CD tool and ensures validation of dependencies and testing of components before integration.
The selective builds feature in Ripple CI only rebuilds the components that are affected by changes, thereby reducing build times and resource consumption.
By integrating Module Federation and Ripple CI into a microfrontend workflow, developers can maintain flexibility without sacrificing predictability.
Using these tools can help transform your workflow and make developing microfrontends more efficient.
For more information on microfrontends, see the increasing agility in Microfrontend Design: A Developer's Guide and Micro Frontends: A Practical Step-by-Step Guide.

REST vs. gRPC: Which Is Better for Performance and Scalability?

REST and gRPC are the most widely used protocols for building APIs, with each having its strengths and weaknesses depending on the use case, performance requirements, and scalability needs of a given application.
REST uses HTTP principles where resources are identified via URLs and actions are performed using standard HTTP methods (GET, POST, PUT, DELETE).
gRPC, developed by Google, is a modern, high-performance RPC framework that uses Protocol Buffers as its default serialization format and HTTP/2 for data exchange. This brings advantages in terms of both performance and scalability.
REST is simpler and widely supported, but its text-based nature makes it less efficient while gRPC is faster, more efficient, and flexible, but has a steeper learning curve.
gRPC tends to outperform REST APIs in several key areas such as data serialization and transfer, latency, and efficiency.
When considering scalability, gRPC offers distinct advantages, especially in distributed systems or microservices architectures, due to its built-in support for streaming and multiplexing.
REST and gRPC have their place in modern application development. REST remains a great choice for simple, public-facing APIs where ease of integration and broad compatibility are key considerations. gRPC with Protobuf offers significant advantages for performance-sensitive, high-volume, or low-latency applications particularly in microservices environments, real-time systems, and scenarios requiring high efficiency and scalability.
The choice between REST and gRPC ultimately depends on the specific needs of the application- whether it’s the simplicity and compatibility of REST or the performance and scalability of gRPC that takes precedence.

Important Elements of System Design and Things to Keep in Mind

System design is the process of defining the architecture, modules, interfaces, and data for a system to satisfy specified requirements.
Key elements of system design include understanding the problem domain, defining clear requirements, choosing the right architecture, using modular design, designing for scalability, considering security, and thorough testing.
Understanding the problem domain involves identifying user needs, business requirements, and constraints.
Choosing the right architecture involves considering options like monolithic, microservices, and layered (N-Tier) architectures.

Screener.in Search API: A Performance Checkup! 🔎

The article examines the Screener.in stock screener API and highlights inefficient practices in the search functionality.
The search sends a new API call to the server for each keystroke made by the user.
This inefficient use of network resources leads to server and network overload.
To fix this issue, the article suggests debouncing, throttling, and client-side caching techniques.
Debouncing involves delaying API calls until the user has paused typing, using a timer with a delay period.
Throttling involves limiting the number of API calls over a specific time period and reducing server load.
Client-side caching stores results from previous searches directly in the user's browser and reduces network activity.
The article also recommends sending one big message with all the search information instead of lots of little ones.
Optimizing search functionalities is vital for building efficient applications.
The synergy of debouncing, throttling, client-side caching, and batch requests can dramatically improve search system’s performance.

Chrome DevTools: Everything You Need to Know

Chrome DevTools is an essential tool for every web developer as it offers a wide range of features that make the debugging and optimization process more straightforward.
The Performance tab on DevTools can be used to collect some metrics for the performance of a web application. In the recently versions of Chrome, the web vitals are the three essential metrics for a healthy website.
Web Vitals are a set of essential metrics that Google defines to measure user experience regarding a website's performance.
Last Contentful Paint (LCP) measures the web page loading performance, whereas First Input Delay (FID) measures the time it takes from the moment the user first interacts with the page.
Cumulative Layout Shift (CLS) measures visual stability or the number of unexpected layout shifts that occur during user interactions.
In the application tab, users can see the storage of a web application like Session Storage, Local Storage, IndexDB, Cookies, and the Service Worker if the application uses this resource.
IndexedDB is a more advanced local database that allows the storage of large amounts of structured data, such as JavaScript objects, and can be used to store data related to offline web applications.
In the network tab, users can analyze what was sent in the request, such as the request body, header, cookies, and much more.
In the Source tab, developers can analyze an application's source code and third-party libraries to perform a debug.
Google's Chrome User Experience Report (CrUX) is a valuable source for measuring the actual experience of using a website and can be accessed through tools such as Google PageSpeed™ Insights, Google Search Console, or directly on tools like Chrome DevTools.
