海外TECH	DEV Community	Guia Básico sobre Princípios de Programação e SOLID	https://dev.to/guilhermemanzano/guia-basico-sobre-principios-de-projetos-e-solid-4m59	Guia Básico sobre Princípios de Programação e SOLIDEstudando um pouco sobre Clean Code e boas práticas no desenvolvimento de software me deparei com os princípios de programação e princípios SOLID Aliados com o Clean Code eles são uma ferramenta poderosa para mantermos um código de fácil entendimento fácil refatoração e com o menor número possíveis de bugs Princípios de programação são recomendações concretas que os desenvolvedores devem seguir para atender às propriedades de projeto Cinco destes princípios formam os Princípios SOLID em português são eles Responsabilidade Única Aberto Fechado Substituição de Liskov Segregação de Interfaces e Inversão de Dependência Estes princípios aliados com as práticas de Clean Code permite que desenvolvemos códigos mais maleáveis que são mais fáceis de se refatorar e melhorar Vou descrever um pouco dos princípios do SOLID além de falar sobre o princípio de Prefira Composição a Herança e do princípio de Demeter Princípio de Responsabilidade ÚnicaEste princípio relacionado a coesão diz que cada classe pode ser aplicado a funções componentes entidades entre outros deve ter apenas uma responsabilidade ou seja deve existir apenas um motivo para modificar qualquer classe em um sistema Ou seja este princípio prega que não devemos criar uma Classe Deus que por exemplo valida e mail lêarquivo acessa o banco de dados grava no banco de dados consulta uma API entre outros Como cada classe deve ter apenas uma função neste exemplo devemos ter uma classe apenas para acessar o banco de dados outra apenas para ler um arquivo outra para validar um e mail e assim por diante cada qual com sua função Princípio Aberto FechadoEste princípio diz que uma classe deve estar fechada para modificações e abertas para extensões Seu objetivo éa construção de classes flexíveis e extensíveis capazes de se adaptarem a diversos cenários de uso sem modificações no seu código fonte Neste princípio o projeto da classe possibilita extensões e customizações através do uso de herança funções de mais alta ordem ou funções lambda e padrões de projeto como Abstract Factory Template Method Strategy Princípio da Segregação de InterfaceEste princípio define que as interfaces têm que ser pequenas coesas e especificas para cada tipo de cliente Trata se de um caso particular de Responsabilidade Única com foco em interfaces relacionado a coesão também o objetivo deste princípio éevitar que clientes dependam de interfaces com métodos que eles não irão usar Ou seja se vocênão for utilizar algum dos métodos daquela interface na classe que pretende implementá la émelhor criar uma nova interface específica para aquela classe do que sobrescrever métodos que não serão utilizados Princípio da Substituição de LiskovEste princípio explicita regras para redefinição de métodos de classes bases em classes filhas Apesar de herança não ser muito utilizada ela pode ser útil em alguns casos específicos A sua vantagem éque comportamentos métodos comuns a classe base e subclasses podem ser implementados uma única vez na classe base e poderão ser herdados em todas as subclasses Alguns exemplos de classes que violam este princípio são aquelas que sobrescrevem ou implementam através de uma interface métodos que não fazem nada pois alguns métodos desta interface sóestásendo utilizado por uma outra classe específica por exemplo lança uma exceção inesperada ou que retorna valores de tipos diferentes da classe base Princípio de Inversão de DependênciaEste princípio recomenda que uma classe cliente deve estabelecer dependências prioritariamente com abstrações e não com implementações concretas pois as abstrações interfaces são mais estáveis do que implementações concretas classes A ideia levantada por este princípio então éde inverter as dependências ou seja ao invés dos clientes dependerem de classes concretas eles devem depender de interfaces A vantagem deste princípio éque quando um cliente se acopla a uma interface ele fica imune a mudanças na implementação dessa interface Prefira Composição a HerançaEste princípio recomenda o uso de composição a herança pois quando usamos herança isso acaba gerando um forte acoplamento entre superclasses e subclasses A herança expõe para subclasses detalhes de implementação das classes fazendo com que a implementação das subclasses se torna tão acoplada àimplementação da classe pai que qualquer mudança nelas pode forçar modificações nas subclasses Uma outra vantagem de se utilizar composição éque a relação entre as classes não éestática permitindo assim fazer mudanças em tempo de execução Princípio de DemeterEste princípio defende que a implementação de um método deve invocar apenas os seguintes outros métodos Da sua própria classe caso De objetos passados como parâmetros caso De objetos criados pelo próprio método caso De atributos da classe do método caso O objetivo deste princípio éevitar problemas de encapsulamento em projeto de sistemas orientados a objetos ele recomenda que os métodos de uma classe devem falar apenas com métodos da própria classe ou com métodos de objetos que eles recebem como parâmetros ou que eles criam	2021-10-24 14:12:26
海外TECH	DEV Community	Microservices Architecture for Roadrunners | 6 key benefits	https://dev.to/developertharun/microservices-architecture-for-roadrunners-6-key-benefits-4898	Microservices Architecture for Roadrunners key benefits Freaky AnalogyImagine a feature in your application that records the number of times a user has visited a page Suppose there is a bug in the code that does this and if you have put all of the code that you need to render the application in a single code base then chances are your entire application will go down and you will face downtime just because of a bug in a small part of the code Now imagine an alternate scenario where the code that is responsible to record the number of times the user has visited a page is isolated from the entire application and any bug or downtime in it will in no ways affect the functionality of the application as a whole apart from just this feature not working Introducing microservices architecture Microservices architectureMicroservices architecture is a technique where you have multiple tiny applications that function together towards serving an entire application in such a way that each of the smaller applications can be worked on independently and doesn t have major impact on other smaller applications that form the entire application If you observe the above illustration  The monolithic architecture has all components of the social media application together and needs all to function properly in order for the application as a whole to serve traffic Here all services are tightly coupled with each other Even if one of the service is malfunctioning then it might affect the application as a whole  The microservices architecture has individual services functioning in a loosely coupled manner The social media application would be further divided into smaller applications for any depth This means the authentication app in the above diagram could be further divided into several smaller applications These applications can have their individual teams who work on them independently and the applications would have interfaces through which they communicate with each other It would be possible to allocate resources on a granular level to only those applications that need it If one of the smaller application say the Ads app goes down either for maintenance or due to a bug even then rest of the application should function as usual besides the issue with displaying the Ads on the application Features of Microservices architecture Loosely coupled micro applicationsThe application that follows microservices architecture will consist of multiple smaller applications that are loosely coupled with each other They are least dependent on each other Easily maintainable and testableSince the applications would be isolated individual teams will be able to work on it in parallel have down times when needed without affecting other micro applications will be able to test micro applications individually Independently deployable scalable amp cost savingThe individual teams will be able to deploy the micro services individually rollback or fix bugs when necessary and redeploy when needed without worrying about the rest of the applications The resource allocation can be defined on a granular level for each and every micro service as and when needed and there will be minimal over provisioning thereby saving costs for huge enterprises Fresher friendlyThe new joinees to the project will be able to pick up the responsibilities quicker no matter what the size of the entire application is because of the microservice architecture The stakeholder only needs to pick up the knowledge pertaining to the micro services that his team handles and the interfaces it uses and need not look at the application as a whole at once This significantly reduces the time needed to on board an employee Better fault isolation amp monitoringIndividual teams will be able to monitor their respective microservices They will be able to monitor identify and isolate the issues effectively As discussed earlier this also prevents cascading effect of issues No technical dependencyThe microservices do not have any dependency in the technologies used in building or maintaining the applications They are free to use their own technologies and communicate using an interface like REST APIs This dissolves all technical dependencies across teams Better data security amp complianceEach microservices or smaller application groups can have their own data stores and can prevent other parts of application from accessing it This ensures enhanced security This is also extended to isolation between teams in such a way that only the team that manages the microservice is given access to it even within the same organization Most of the next gen organizations today function based on a microservices architecture that helps them to delegate secure be resilient deliver performant applications and reduce costs You can find more articles here Roadrunners is a series that is aimed at delivering concepts as precisely as possible Here a roadrunner is referred to as a person who does things super fast amp efficiently Are you a roadrunner Thank you	2021-10-24 14:09:14
