Community Picks·4yTop 10 Microservices Design Patterns and Principles
Microservice architecture is structured on the business domain and it's a collection of small autonomous services. Transaction management is the fundamental advantage of a shared database versus a per-service database. Event Sourcing is based on the idea that any change in an entity's state should be captured by the system. The persistence of a business item is accomplished by storing a series of state-changing events.

Ports & Adapters architecture identifies three fundamental blocks of code in a system. In most languages and in its most simple form, the Port will be an Interface, but it might actually be composed of several Interfaces and DTOs.
Community Picks·4yMicro Frontends
Micro Frontends is an architectural approach to frontend development with the idea of thinking of a project as a collection of features independently owned by different teams. Each team is cross-functional and develops its features end-to-end, from database to user interface.

Red Hat Developer·4y8 elements of securing Node.js applications
Security practices apply to both the code itself and your software development process. Validate user input Unvalidated input can result in attacks such as command injection, SQL injection, and denial of service, disrupting your service and corrupting data.
Better Programming·4yHow To Implement a TypeScript Web App With Clean Architecture
The Ultimate Clean Architecture Template for Typescript Applications is a guide on creating a layer-based typescript project template following the principles of clean architecture medium. The user should be able to change the amount of increment/decrement for a counter. The user's counters should be saved if they close the application and open it again. We need a way to store data locally, i.
Hashnode·4yLearn how to build a microservice using Node.js and RabbitMQ.
Learn how to build a microservice using Node.js and RabbitMQ. This tutorial will teach you about microservices and how to create a simple e-commerce microservice architecture with two services; product and order. In the following section, we will look at some of the prerequisites for this tutorial. Make another folder for the routes, call it routes, then inside it, have a file routes.
Hashnode·4yFabric: The new Architecture
Fabric is the React Native forerunner to the old legacy renderer. Fabric takes a different approach to how UI view instances will be created in a React Native application. The new Fabric architecture changes none of this but builds on it, making the experience even more platform specific.
MC++ Blog·4yClassification of Design Patterns
The book "Design Patterns: Elements of Reusable Object-Oriented Software" presents creational patterns, but not destructional patterns. The patterns that are written in bold fonts are the ones I used heavily in my past. All 23 Design Patterns are only variations of CarPart. The same holds for many young people in Germany.
ByteByteGo·4yEP18: Build a chat application. Also...
The diagram is based on the tech talk by Jessica Tai. The micro service architecture focuses on the unification of APIs. With blockchains, we can merge wallet services from different banks into one global service. The diagram below shows how we can leverage the pub-sub functionality of Redis to develop a chat application.
gitconnected·4yMicroservices with Node.js, Kubernetes, and RabbitMQ
Kubernetes (‘K8s’) is an open source system for automating and managing container orchestration that grew out of Google’s Borg, and is now maintained by the Cloud Native Computing Foundation. A microservice architecture means that your app is made up of many smaller, independent applications RABBITMQ_URL. The orders/index.js will be listening for an ‘ORDER’ message and as soon as it gets that message.
Pointer·4ySoftware Visualization — Challenge, Accepted - Spotify Engineering
Spotify System Model presents a set of core entities and abstractions we can use to synthesize data about our software health, ownership, and dependencies. The C4 is a lightweight and straightforward approach to visualizing software. We don’t want to reinvent the wheel, so we kept C4 notation and best practices and replaced its abstraction layer with the Spotify System model.
Pointer·4yEvent Driven Architecture — 5 Pitfalls to Avoid
At Wix we have been gradually migrating our growing set of microservices from the request-reply pattern to event driven architecture over the last few years. Below there are 5 pitfalls that Wix engineers have encountered during our experimentation with event-driven architecture.
ProAndroidDev·4yBuild a Real-Time Android WhatsApp Clone With Jetpack Compose
Build a real-time Android WhatsApp Clone with Jetpack Compose and Stream’s versatile Compose Chat SDK. In this post, you’ll learn how the app architecture was designed and how data flows between different layers. WhatsApp Clone Compose uses Material Theme for styling the overall UI elements and defining custom color schemes with lightColorSceme and darkColorSCEme methods.
Hashnode·4y5 Approaches To Improve As A Software Engineer
If you have meaningful ideas that you can work on, build them as a side project. If you don’t have any idea but want to improve your skills, build any fun project. Sharing knowledge improves soft skills, such as technical writing, communication, and confidence. Building an audience, or at least sharing content online, can bring you new opportunities.
DZone·4ySimplify Your Microservices Architecture: Data API
The data API gateway takes on the responsibility of managing data persistence for hotels, rates, inventory, and other data types. Data types can be added to the gateway by providing a schema or data model. Document-style endpoints can provide a "schema-less" experience in which any valid JSON document can be stored, such as a hotel description.
Container Solutions·4yWTF is Evolutionary Architecture?
Evolutionary architecture is the practice of considering a spectrum of dimensions around the architecture. It’s possible to get caught up in trying to create the perfect architecture that caters to all concerns. Having teams wait for architectural instructions will cause a big bottleneck, which you want to avoid.
Big Nerd Ranch·4yGo Generics in API Design
Go Generics in API Design Go 1.18 has finally landed, and with it comes its own flavor of generics. For example, you should try to handle errors before using panic since the latter will end up exiting your program. Since this compiles, we won’t know this broke something until we deploy and get the bug report.
JavaScript in Plain English·4yReact Native Architecture — Old Vs New
React Native helps us to build cross-platform applications by creating native elements which can then be easily understood by the native world. The current architecture is based on 3 major threads- Main/Native/UI thread. The new architecture introduces a different layer known as JavaScript Interface (JSI) as a replacement for React Native bridge.
Discover .NET·4yShared Database between Services? Maybe!
Is a shared database a good or bad idea when working in a large system that's decomposed of many different services? Or should every service have its own database? My answer is yes and no, but it’s all about data ownership. Using a local cache when executing a command means using stale data.
MC++ Blog·4yThe Structure of Patterns
"Design Patterns: Elements of Reusable Object-Oriented Software Architecture" and "patterns" are the most influential books ever written about software development. Christopher Alexander uses the three adjectives useful, usable and used to describe the benefits of patterns. The strategy pattern is so baked in the design of the Standard Template Library that we may not see it.
