海外TECH	DEV Community	Decode Adapter Pattern	https://dev.to/gauravratnawat/decode-adapter-pattern-2i4p	Decode Adapter Pattern When to useTo wrap an existing class with a new interface To perform impedance matching IntentConvert the interface of a class into another interface clients expect Adapter lets classes work together that couldn t otherwise because of incompatible interfaces ComponentsTarget defines the domain specific interface that Client uses Adapter adapts the interface Adaptee to the Target interface Adaptee defines an existing interface that needs adapting Client collaborates with objects conforming to the Target interface StructureBeforeAfter ImplementationAssume that you have an e commerce application which is serving your customers for a long time This e commerce application is using a Legacy Order Management System OMS Due to the high maintenance cost and degraded performance of the legacy OMS software you have decided to use a cheap and efficient OMS software which is readily available in the market However you realize that the interfaces are different in the new software and it requires a lot of code change in the existing e commerce application Adapter design pattern can be very useful in these situations Instead of modifying your e commerce application to use the new interfaces you can write a wrapper class that acts as a bridge between your e commerce application and the new OMS software With this approach the e commerce application can still use the old interface Adapter design pattern can be implemented in two ways One using the inheritance method Class Adapter and second using the composition Object Adapter The following example depicts the implementation of Object adapter Below is the code that uses the LegacyOMS package com gaurav adapter public class Item private String name private double price public Item String name double price this name name this price price public String getName return name public double getPrice return price package com gaurav adapter public class Payment public String type public double amount public Payment String type double amount super this type type this amount amount public void pay System out println type amount package com gaurav adapter import java util ArrayList import java util List public class LegacyOMS The Legacy OMS accepts input in XML format List cart new ArrayList List payments new ArrayList public void addItem Item itemXml cart add itemXml System out println itemXml getName itemXml getPrice public void makePayment Payment paymentXml payments add paymentXml paymentXml pay The client code package com gaurav client import com gaurav adapter Item import com gaurav adapter OMSAdapter import com gaurav adapter Payment public class AdapterClient public static void main String args Create an order and add items LegacyOMS oms new LegacyOMS oms addItem new Item Italian Pizza oms addItem new Item Wine oms addItem new Item Beer oms addItem new Item Red Apple oms addItem new Item Almonds System out println Create payment and make payment oms makePayment new Payment CASH oms makePayment new Payment CREDIT oms makePayment new Payment DEBIT System out println When the OMS needs to be swapped you can simply create an Adapter class with same interface that the client uses This adapter wrapper class maps the client interface to the adaptee New OMS interface package com gaurav adapter import java util ArrayList import java util List public class NewOMS The new OMS accepts input in JSON format List cart new ArrayList List payments new ArrayList public void addToBasket Item itemJson cart add itemJson System out println itemJson getName itemJson getPrice public void pay Payment paymentJson payments add paymentJson paymentJson pay package com gaurav adapter public class OMSAdapter Object Adapter uses composition private NewOMS newOMS public OMSAdapter newOMS new NewOMS public void addItem Item item convertXmlToJson item newOMS addToBasket item public void makePayment Payment p convertXmlToJson p newOMS pay p The new OMS accepts only Json input Convert the client requests from XML to Json private void convertXmlToJson Object o System out println Converted from XML to JSON The new client code The client interacts in the same way as before package com gaurav client import com gaurav adapter Item import com gaurav adapter OMSAdapter import com gaurav adapter Payment public class AdapterClient public static void main String args Create an order and add items LegacyOMS oms new LegacyOMS Use Adapter class with the same

Red Apple Almonds CASH CREDIT DEBIT BenefitsClass adapter can override adaptee s behavior Objects adapter allows a single adapter to work with many adaptees Helps achieve reusability and flexibility Client class is not complicated by having to use a different interface and can use polymorphism to swap between different implementations of adapters DrawbacksObject adapter involves an extra level of

海外TECH	DEV Community	State Management for your React Apps - Simplified!	https://dev.to/fahadim87/state-management-for-your-react-apps-simplified-6fm	State Management for your React Apps Simplified Hi there fellow developers In this blog I will show you how to implement a scalable state management solution for your React apps without the need of any third party library or toolkit If you guys are unfamiliar with state management and why you might need it for your projects there are countless and I mean literally hundreds of articles explaining the benefits of state management in frontend apps I ll link to a great one here so you can read to your heart s content Now I am aware that there are many solutions for state management in React apps and you ve probably heard the term Redux thrown around when someone mentions React state management Redux is a fantastic tool and is very popular in the React community and rightly so With its great documentation and robust set of developer tools it has become the gold standard for state management in frontend JavaScript apps However did you know that you can achieve similar results using native tools baked right into React That s what we will attempt to accomplish today using React s Context API and Hooks Simply put Context API provides a way to pass data between React components without passing down props something which can quickly become very cumbersome Context API itself is cool and all but combine it with React hooks and you re looking a pretty nice state management solution for your projects And the best thing no dependencies and no need to install any third party library I think I ve taken way too long in explaining now let s get to the fun part i e coding Let s write some code Implementing Context API requires steps Creating ContextCreating a Provider componentConsuming the ContextLet s go over these with a simple todo app using the Context API Disclaimer I won t be focusing on the styling or CSS because frankly that s not what this blog is about The focus of this project is learning about React and not about designing beautiful UIs Create a new react project using npx create react app react context todo Feel free to name it whatever you like Jump into your favorite code editor I ll be using VS Code for this example Then start the dev server using npm start which will launch the app on https localhost Implementing Context APINow we can start to implement the Context API Create a new folder src context which will contain all the files for state management we ll be needing for this project Within this folder create a new file Context js which will serve as the basis for creating and exporting context Context jsimport createContext from react export const context createContext Create another file src context GlobalState js which we will use to create the initial state for our project and also pass it to the Provider component GlobalState jsimport React useReducer from react import GlobalContext from AppContext import AppReducer from AppReducer Define initial stateconst initialState todos Provider componentexport const GlobalProvider children gt const state dispatch useReducer AppReducer initialState Actions function deleteTodo id dispatch type DELETE TODO payload id function addTodo todo dispatch type ADD TODO payload todo return lt GlobalContext Provider value todos state todos deleteTodo addTodo gt children lt GlobalContext Provider gt Woah that s a lot of code Don t sweat I ll explain in simple terms Basically Context API requires a Provider component and initial state to do its magic We pass the state to the Provider and that state is accessible throughout our React app With me so far Good In this file we import the Context we exported earlier AppReducer which we will create shortly and a React hook called useReducer which is an alternative to useState It allows you to pass an initial state and also define actions for manipulating the state According to the React docs useReducer is usually preferable to useState when you have complex state logic that involves multiple sub values or when the next state depends on the previous one Then we define the initial state which is an array of todos and create a Provider component to define our actions addTodo and deleteTodo Actions are functions that are dispatched whenever we want to change the state like adding a new todo or deleting an existing one If you are unfamiliar with this terminology I would suggest reading up on the Flux Pattern Each action includes a payload which is a value passed to it when the action is invoked Think of it like calling a function by passing a value to it Finally we pass the initial state and actions to the Provider and export it The components which are wrapped inside the Provider will have access to the state and actions Now we will create the final piece of the puzzle the Reducer which is responsible for changing the state and returning the updated state Create a new file called src context AppReducer js inside the context folder and add the following code AppReducer jsexport default state action gt switch action type case DELETE TODO return state todos state todos filter todo gt todo id action payload case ADD TODO return state todos action payload state todos default return state Here we use a simple Switch Case statement to update the state depending on the type of action invoked and return the updated state Take care to NOT mutate the state rather make a copy of the state using the spread operator first before changing it All that is left now is to wrap the App component with the Provider component so that the state is accessible to all components within the application import App css import GlobalProvider from context GlobalState function App return lt GlobalProvider gt lt div className App gt lt h gt React Context Todo lt h gt lt div gt lt GlobalProvider gt export default App OK now that you have created and exported the context and defined the actions you can now begin using it in your components Finishing the App Consuming ContextNow let s complete the todo app using Context API I won t go into the details of creating React components since that would take way too long I am assuming you re familiar with the basics of React and JavaScript ES Create a new folder src components and add the following files into it AddTodo jsimport useState useContext from react import GlobalContext from context AppContext import nanoid from nanoid export const AddTodo gt const text setText useState const addTodo useContext GlobalContext const onSubmit e gt e preventDefault const newTodo id nanoid text text addTodo newTodo setText return lt form onSubmit onSubmit gt lt input type text placeholder Add Todo value text onChange e gt setText e target value gt lt button type submit gt Add Todo lt button gt lt form gt To get the values from the Context we import another React hook useContext and pass it the GlobalContext We can then de structure the required values from it In the AddTodo component we have a simple input to get the text that the user types For generating a unique id we are using the nanoid npm package TodoList jsimport Todo from Todo import GlobalContext from context AppContext import useContext from react export const TodoList gt const todos deleteTodo useContext GlobalContext return lt div gt todos map todo gt lt Todo key todo id todo todo deleteTodo deleteTodo gt lt div gt Here we are simple looping over the todos using the map method and rendering out the Todo component for each We are also passing the deleteTodo method to each todo Todo jsexport const Todo todo deleteTodo gt return lt div gt lt span gt todo text lt span gt lt button onClick gt deleteTodo todo id gt x lt button gt lt div gt Here is the App component after the application is complete import App css import AddTodo from components AddTodo import TodoList from components TodoList import GlobalProvider from context GlobalState function App return lt GlobalProvider gt lt div className App gt lt h gt React Context Todo lt h gt lt AddTodo gt lt TodoList gt lt div gt lt GlobalProvider gt export default App And here is the final working app I admit its not pretty but it gets the job done and demonstrates the point pretty nicely Feel free to add more features or style the app using your favorite CSS framework to make it more exciting Code for this project GitHub Repo Thanks for ReadingAs always I hoped you enjoyed reading this blog Feel free to leave any questions or suggestions in
