海外TECH	DEV Community	Design Patterns in PHP 8: Abstract factory	https://dev.to/zhukmax/design-patterns-in-php-8-abstract-factory-32d1	Design Patterns in PHP Abstract factoryHello fellow developers ‍In our coding journey today we re going to unravel the intricacies of the Abstract Factory design pattern This pattern is a gem in the realm of creational design patterns serving as a super factory or a factory of factories if you will Consider a scenario where we re architecting a web application that needs to cater to multiple databases say MySQL and PostgreSQL The Abstract Factory pattern can be our savior here enabling us to construct families of related objects that represent different database operations These operations could range from establishing a connection executing a query to managing a transaction interface DBAbstractFactory public function createConnection public function createQuery public function createTransaction class MySQLFactory implements DBAbstractFactory public function createConnection return new MySQLConnection public function createQuery return new MySQLQuery public function createTransaction return new MySQLTransaction class PostgreSQLFactory implements DBAbstractFactory public function createConnection return new PostgreSQLConnection public function createQuery return new PostgreSQLQuery public function createTransaction return new PostgreSQLTransaction In this code snippet DBAbstractFactory is our abstract factory that lays out the creation methods blueprint MySQLFactory and PostgreSQLFactory are the concrete factories that breathe life into these blueprints Each concrete factory is tied to a specific product variant For instance MySQLFactory is solely responsible for creating MySQL database operations The beauty of the Abstract Factory pattern lies in its ability to ensure that a group of related objects is always conjured up together thereby making it a breeze to enforce this constraint To wrap up the Abstract Factory pattern is a potent tool in your design pattern arsenal It s especially handy when your code needs to spawn families of related objects without being tied down to their concrete classes By leveraging this pattern you can infuse your code with greater flexibility enhance its maintainability and gear it up to tackle future changes or additions with ease P S If you found this article helpful and want to dive deeper into design patterns in PHP and TypeScript I have some exciting news for you I m currently writing a book that extensively covers these topics It s packed with practical examples clear explanations and real world scenarios where these patterns can be applied The book is designed to help both beginners and experienced developers gain a solid understanding of design patterns and how to implement them in PHP and TypeScript Whether you re looking to brush up on your knowledge or learn something new this book has got you covered You can subscribe to my blog on dev to or connect on linkedin and then you will receive a notification as soon as the book is ready I can t wait for you to read it and take your coding skills to the next level Photo by Ant Rozetsky on Unsplash	2023-08-29 06:45:47
海外TECH	DEV Community	Building Microservices with NestJS	https://dev.to/scofieldidehen/building-microservices-with-nestjs-4c2p	Building Microservices with NestJSThe Architecture of Microservices Microservices architecture is a way of developing software systems as independently deployable services In this architecture an application is built as a collection of small modular services communicating with each other Each microservice focuses on doing one thing well and can be developed tested deployed and scaled independently Building microservices with NestJS is important for several reasons Firstly NestJS provides an optimized framework designed specifically for microservices architecture It handles challenges like dependency management asynchronous communication and scalability that are common in complex microservices ecosystems NestJS uses progressive JavaScript TypeScript and proven architectural patterns like dependency injection to create consistent enterprise grade services Secondly NestJS increases developer productivity and velocity The declarative modular architecture and out of the box developer tooling like the CLI allows developers to focus on business logic rather than building boilerplate Built in capabilities like validation serialization and CORS handling also accelerate development Some key characteristics of microservices architecture Services are independently deployable each service can be deployed independently without needing to deploy the entire application Services are organized around capabilities services are broken down based on business capabilities Services can be implemented using different programming languages and technologies since each service is independent they can use whatever language or technology makes the most sense Services communicate via APIs services expose APIs that other services can consume Common protocols used are REST gRPC or asynchronous messaging Services are loosely coupled and highly cohesive but loosely coupled with others This allows for easy maintenance and flexibility Services can be independently scaled services can be scaled based on demand allowing high scalability Microservices architecture enables easier agile development and deployment of complex applications It also helps with scalability and maintaining services The downside is the complexity of coordinating and deploying many independent services NestJS Advantages for Microservices NestJS is a progressive Node js framework that provides an ideal toolkit for building efficient scalable microservices in TypeScript Here are some of the advantages of using NestJS Built in Support for Microservices NestJS has first class support for microservices architecture It makes it easy to build independent deployable services Dependency Injection NestJS provides dependency injection out of the box This allows for loose coupling between services and better modularity Easy to Scale NestJS uses Node js and JavaScript so it s easy to scale microservices across multiple nodes The architecture also aids in scalability TypeScript NestJS uses TypeScript which provides type safety and other benefits for large enterprise applications Modular with MVC Code is modularized into modules controllers services and providers This makes code easier to maintain and organize at scale Built in CLI NestJS CLI allows quick boilerplate code generation allowing developers to focus on business logic First class Support for Open APIs and Protocols NestJS works well with common microservice API protocols like gRPC MQTT Redis and more Rich Ecosystem of Modules A rich module ecosystem for tasks like configuration logging caching rate limiting etc helps accelerate development NestJS combines the best features of Node TypeScript and architectural patterns like dependency injection to build scalable and maintainable microservices Setup of the Project Here are the steps to set up a new microservice project with NestJS Step Install Nest CLI using npm npm i g nestjs cliThis installs the NestJS CLI globally on your system Step New Microservice should be CreatedUse the Nest CLI to generate a new microservice application nest new microservice nameThis will scaffold a new microservice app folders files and sample code Step Navigate to the directory of the newly created microservice applicationcd microservice nameChange to the app directory that was just created Step Creating a ModuleModules are used to organize code into logical boundaries in NestJS Under src create a new module nest g module catsThis will generate a CatsModule module under src cats cats module tsStep Creating a Controller Controllers handle incoming requests and return responses in NestJS Generate a new controller nest g controller catsThis will create a CatsController under src cats cats controller ts that is already imported into the CatsModuleStep Creating a ServiceServices contain business logic and handle data access and processing Generate a cats service nest g service catsThis creates a CatsService service class under src cats cats service ts that is imported into the CatsModule Step Configure CommunicationThe generated files include sample code showing how the controller uses the service The controller s request handling methods can call methods on the service class to execute business logic Step Main File ConfigurationOpen src main ts and update any required configuration for your microservice app The NestFactory is used to create the Nest app instance Step Start your microservice by runningnpm run startThis will compile the TypeScript code and start the application The microservice will be running on the configured port Module OrganizationNestJS promotes modularity by organizing code into modules controllers services and providers Here is an example workflow to create a modular microservice Example How to organize a microservice in NestJS with its module controller and service Step Create a new microservice called user servicenest new user serviceStep Navigate to Microservice Directorycd user service lt Step Create a new module for the microservicenest g module usersThis will generate a UsersModuleStep Create a controller that handles incoming HTTP requestsnest g controller usersThis creates a UsersControllerStep Create a service that contains the business logicnest g service usersThis generates a UsersServiceStep Define routes for the controllerIn UsersController define routes and handler methods for requests Get findOne   return this usersService findOne   Step Service LogicImplement business logic for the service method called by the controller findOne   return user Step Update Module Definition import the controller and serviceIn UsersModule import the controller and service imports UsersController UsersService Step Bootstrap the Microservice Update the src main tsAdd required app setup code const app await NestFactory create UsersModule await app listen Step Run the microservicenpm run startThis modular organization makes it easy to maintain clean independent services The controller handles web requests while the service handles business logic using providers The module ties them together In summary NestJS provides an ideal framework for building scalable microservices using Node js and TypeScript With its efficient modularity via modules services and developer tooling NestJS accelerates microservice development and deployment If you find this post exciting find more exciting posts on Learnhub
