Best Practices for API Security: JavaScript and Python Examples 

This article outlines how to transition from singletons to dependency injection in a SwiftUI app with minimal effort. If you're here, you likely already know that you should avoid singletons with various of reasons like: Hidden Dependencies: Classes rely on singletons without explicit indicators, making it harder to track app dependencies and leading to unintended coupling.
Circular Dependencies: Singletons depending on each other can create cycles, leading to initialization deadlocks as instances wait for each other.
Testing Challenges: Using singletons complicates testing and SwiftUI previews since singletons can't easily be swapped for mocks. Lack of Flexibility: Singletons make it difficult to provide different implementations for different environments (e.g., live vs. mock versions for testing). And many others. Dependency Injection To overcome most issues we can use Dependency injection (DI). Using it, swapping in a new implementation becomes much easier, as components don’t rely on a single shared instance but on protocols that can be implemented in different ways. This promotes flexibility, easier testing, and adaptability as app requirements evolve. Constructor Injection Constructor injection is a straightforward technique for injecting dependencies by passing them through initializers. While effective, it often increases the size and complexity of initializers. A common challenge with constructor injection is passing dependencies through a deep UI hierarchy. If a dependency is only needed on a specific screen but must be passed down through multiple intermediary screens, this can quickly become cumbersome. One way to handle this is by using the Coordinator pattern, which centralizes navigation and manages dependencies more efficiently. Check out this article to learn how to make it. Why Not Use @EnvironmentObject? While @EnvironmentObject simplifies dependency sharing in SwiftUI, it has limitations: It only works with ObservableObject
It doesn’t allow using protocols for implementation switching.
It only works in SwiftUI views hierarchy
It only checks for service existence when accessed, increasing the risk of unintentional omissions in views. Dependency injection with property wrappers This is similar to the @EnvironmentObject solution where the dependency management happens inside of property wrappers, but without drawbacks. DependencyContainer This small library contains only a couple files, can be copied directly into your project or integrated via SPM. Please, make sure you put a star on it if you like it. Here is the link on GitHub. Let’s create an example of the service we need to pass as a dependency. As we are assuming that we are going to make a mock for testing, we need to implement our service as a protocol. Also we make it as ObservableObject, to review additional features of the framework. import Combine

protocol DataRepository: Actor, ObservableObject {
    
    func fetchData() async throws
}

actor DataRepositoryImp: DataRepository {
    
    func fetchData() async throws {
        // do real stuff
    }
}

actor DataRepositoryMock: DataRepository {
    
    func fetchData() async throws {
        // do mocked stuff
    }
} Defining a DI container Once integrated, you’ll set up a DI container to manage your services. Each service requires a unique key. You have no limitations in creating keys with the same service type. import DependencyContainer

extension DI {
    static let data = Key<any DataRepository>()
} Next let’s create a function for registering service in DI Container. extension DI.Container {
    
    static func setup() {
        register(DI.data, DataRepositoryImp())
    }
} Then, call this function at app startup. @main
struct ExampleApp: App {
    
    @MainActor final class AppState: ObservableObject {
        
        init() {
            DI.Container.setup()
        }
    }
    @StateObject var state = AppState()
    
    var body: some Scene {
        WindowGroup {
            MainView()
        }
    }
} Injecting Dependencies The actual injection is done with several property wrappers. The most common one is @DI.Static. You just need to pass a key we defined earlier. struct MainView: View {
    
    @DI.Static(DI.data) var data
    
    var body: some View {
        Color.clear.task {
            try? await data.fetchData()
        }
    }
} The points we need to make attention to: No Need to Specify Type. As you may have noticed we don’t need to write a type here, because Swift gets the type from the key.
It’s very convenient in case you start with a concrete type for your service and later decide to use a protocol to enable mocking. You only need to update the type in the key definition. This change propagates automatically without requiring updates to any code referencing that service. Dependency Existence Checked on Initialization. The property wrapper checks that the service exists when initialized. This helps prevent accidental circular dependencies, where services might try to reference each other. The framework enforces a clear initialization order, encouraging thoughtful dependency management and avoiding deadlocks. Additional property wrappers: @DI.Observed Use this in SwiftUI views when your service is ObservableObject. Views will be updated when the service is changed. struct MainView: View {
    
    //updates the view when data is posting objectWillChange
    @DI.Observed(DI.data) var data
    
    var body: some View {
        Color.clear.task {
            try? await data.fetchData()
        }
    }
} @DI.RePublished Should be used in ObservableObject. If your service is ObservableObject, the update will be republished further by the owner of the property wrapper. struct MainView: View {
    
    final class State: ObservableObject {
        
        // Republishes the data.objectWillChange to the State.objectWillChange
        // The view will be updated
        @DI.RePublished(DI.data) var data
    }
    
    @StateObject var state = State()
    
    var body: some View {
        Color.clear.task {
            try? await data.fetchData()
        }
    }
} In addition, if you have nested services you can use a key path in property wrappers. In this case the observing logic uses the service referenced by a keypath. @DI.Static(DI.data, \.innerService) var innerService

@DI.Observed(DI.data, \.innerService) var innerService

@DI.RePublished(DI.data, \.innerService) var innerService Mocking To swap out implementations for testing or previews, you have two options: Initialize with mocked dependency
MainView(data: .init(value: DataRepositoryMock())) Replace service with mock in DI Container
DI.Container.register(DI.data, DataRepositoryMock())

Build a Real-Time Crypto Tracker with CoinGecko API and React.js

React ⚛️is the most famous UI library in front-end development today. For developers looking to stay ahead of the React race, understanding new React 19 features is essential. Overview of the Features ⚛️React compiler
🗄️ Server components 🖥
🔄Automatic Batching📦
🗒️SEO Metadata
📈Improved Data Fetching with Suspense
💼 Assets Loading
🪝 Enhanced hooks The Revolution of React 19 is exciting and interesting. Let’s read now! ⚛️ React Compiler ⚛️ React19 is getting a new helper called the React Compiler 💡. It's like a smart code-compiling friend that makes your code work faster without you having to do extra work. This means people who make websites can write simpler code, and the compiler will make sure it runs really well. It's like having a super-smart assistant that cleans up and organizes your room for you, so you can focus on playing and having fun with React! 🗄️ Server Components 🖥 React19 comes with the superpower “🖥Server Components.” It's like having a smart render tool that does some of the work before you even ask for it! React19  renders UI components on the server, separate from your client-side app or traditional server-side rendering (SSR) setup. By pre-rendering components on the server, RSCs can automatically improve page speed times. This means when you open a website, the pictures and words show up much faster. It's especially helpful for websites with lots of cool stuff on them. The best part is that these server components can work in different ways depending on what the website needs. Code Example: Server Components // ServerComponent.server.js export default function ServerComponent() { return <div>Hello from the server!</div>; } // App.client.js import React from 'react'; import { createRoot } from 'react-dom/client'; import ServerComponent from './ServerComponent.server'; function App() { return ( <div> <ServerComponent /> </div> ); } const root = createRoot(document.getElementById('root')); root.render(<App />); So, server components make websites load super quick which means less waiting and more speed for you! Don't Waste Time Building React UIs: Check out Monster React Dashboard Template Now! 🔄Automatic Batching📦 React 19 introduces automatic batching for all updates inside event handlers. This means that multiple state updates inside a single event handler will now be batched automatically, leading to fewer re-renders and improved performance. Code Example: Automatic Batching import React, { useState } from 'react'; import { createRoot } from 'react-dom/client'; function App() { const [count, setCount] = useState(0); const [text, setText] = useState(''); const handleClick = () => { setCount(count + 1); setText('Updated text'); }; return ( <div> <button onClick={handleClick}>Update</button> <div>Count: {count}</div> <div>Text: {text}</div> </div> ); } 🗒️SEO Metadata 📝 React 19 is now an AutoSEO Feature that helps websites be found on the internet! Now, React simplifies SEO-sensitive elements and you can easily control titles, descriptions, and other SEO-relevant elements directly within your React application. This way, when someone looks for something on the internet, they can find the right websites faster. 📈Improved Data Fetching With Suspense React 19 builds on the Suspense feature to make data fetching easier and more intuitive. With the new data fetching capabilities, you can now handle asynchronous operations more gracefully within your components. Code Example: Data Fetching with Suspense import React, { Suspense } from 'react'; import { createRoot } from 'react-dom/client'; const fetchData = () => { return new Promise(resolve => { setTimeout(() => { resolve('Data fetched from server'); }, 2000); }); }; const DataComponent = React.lazy(async () => { const data = await fetchData(); return { default: () => <div>{data}</div> }; }); function App() { return ( <div> <Suspense fallback={<div>Loading...</div>}> <DataComponent /> </Suspense> </div> ); } const root = createRoot(document.getElementById('root')); root.render(<App />); 💼 Assets Loading React 19 has a feature where Assets Loads Auto in the background so websites work faster and look better! It starts loading pictures and other stuff for the next page while you're still looking at the current one. This means when you click to go to a new page, it shows up super fast! Have you ever seen a website that looks weird for a split second when it first loads? Like the words are in the wrong place or the colors are all mixed up? React 19 fixes this too. It makes sure everything looks just right before showing it to you.
Code Example: Concurrent Rendering import React, { useState, Suspense } from 'react'; import { createRoot } from 'react-dom/client'; const SlowComponent = React.lazy(() => import('./SlowComponent')); function App() { const [show, setShow] = useState(false); return ( <div> <button onClick={() => setShow(true)}>Show Slow Component</button> <Suspense fallback={<div>Loading...</div>}> {show && <SlowComponent />} </Suspense> </div> ); } const root = createRoot(document.getElementById('root')); root.render(<App />); This way, the website can work on loading stuff in the background without bothering you while you're using it. Focus on what matters. Build Feature-Rich React Apps with MaterialPRO Hooks React 19 introduces new hooks to help manage events and optimistic UI updates more effectively. The useEvent hook provides a simpler way to handle event listeners, while the useOptimistic hook helps manage optimistic UI states.

React 🗄️ Server Components 🖥 🗄️ Server Components 🖥 React19 comes with the superpower “🖥Server Components.” React19 comes with the superpower “🖥Server Components.” It's like having a smart render tool that does some of the work before you even ask for it! It's like having a smart render tool that does some of the work before you even ask for it! React19  renders UI components on the server, separate from your client-side app or traditional server-side rendering (SSR) setup. By pre-rendering components on the server, RSCs can automatically improve page speed times. React19  renders UI components on the server, separate from your client-side app or traditional server-side rendering (SSR) setup. By pre-rendering components on the server, RSCs can automatically improve page speed times. This means when you open a website, the pictures and words show up much faster. It's especially helpful for websites with lots of cool stuff on them. The best part is that these server components can work in different ways depending on what the website needs. This means when you open a website, the pictures and words show up much faster. It's especially helpful for websites with lots of cool stuff on them. The best part is that these server components can work in different ways depending on what the website needs. Code Example: Server Components Code Example: Server Components // ServerComponent.server.js // ServerComponent.server.js export default function ServerComponent() { export default function ServerComponent() { return <div>Hello from the server!</div>; return <div>Hello from the server!</div>; } } // App.client.js // App.client.js import React from 'react'; import React from 'react'; import { createRoot } from 'react-dom/client'; import { createRoot } from 'react-dom/client'; import ServerComponent from './ServerComponent.server'; import ServerComponent from './ServerComponent.server'; function App() { function App() { return ( return ( <div> <div> <ServerComponent /> <ServerComponent /> </div> </div> ); ); } } const root = createRoot(document.getElementById('root')); const root = createRoot(document.getElementById('root')); root.render(<App />); root.render(<App />); So, server components make websites load super quick which means less waiting and more speed for you! Don't Waste Time Building React UIs: Check out Monster React Dashboard Template Now! Monster React Dashboard Template 🔄Automatic Batching📦 🔄Automatic Batching📦 React 19 introduces automatic batching for all updates inside event handlers. This means that multiple state updates inside a single event handler will now be batched automatically, leading to fewer re-renders and improved performance. React 19 introduces automatic batching for all updates inside event handlers. This means that multiple state updates inside a single event handler will now be batched automatically, leading to fewer re-renders and improved performance. Code Example: Automatic Batching Code Example: Automatic Batching import React, { useState } from 'react'; import React, { useState } from 'react'; import { createRoot } from 'react-dom/client'; import { createRoot } from 'react-dom/client'; function App() { function App() { const [count, setCount] = useState(0); const [count, setCount] = useState(0); const [text, setText] = useState(''); const [text, setText] = useState(''); const handleClick = () => { const handleClick = () => { setCount(count + 1); setCount(count + 1); setText('Updated text'); setText('Updated text'); }; }; return ( return ( <div> <div> <button onClick={handleClick}>Update</button> <button onClick={handleClick}>Update</button> <div>Count: {count}</div> <div>Count: {count}</div> <div>Text: {text}</div> <div>Text: {text}</div> </div> </div> ); ); } } 🗒️SEO Metadata 📝 🗒️SEO Metadata 📝 React 19 is now an AutoSEO Feature that helps websites be found on the internet! Now, React simplifies SEO-sensitive elements and you can easily control titles, descriptions, and other SEO-relevant elements directly within your React application. This way, when someone looks for something on the internet, they can find the right websites faster. 📈Improved Data Fetching With Suspense React 19 builds on the Suspense feature to make data fetching easier and more intuitive. With the new data fetching capabilities, you can now handle asynchronous operations more gracefully within your components. Code Example: Data Fetching with Suspense Code Example: Data Fetching with Suspense import React, { Suspense } from 'react'; import React, { Suspense } from 'react'; import { createRoot } from 'react-dom/client'; import { createRoot } from 'react-dom/client'; const fetchData = () => { const fetchData = () => { return new Promise(resolve => { return new Promise(resolve => { setTimeout(() => { setTimeout(() => { resolve('Data fetched from server'); resolve('Data fetched from server'); }, 2000); }, 2000); }); }); }; }; const DataComponent = React.lazy(async () => { const DataComponent = React.lazy(async () => { const data = await fetchData(); const data = await fetchData(); return { return { default: () => <div>{data}</div> default: () => <div>{data}</div> }; }; }); }); function App() { function App() { return ( return ( <div> <div> <Suspense fallback={<div>Loading...</div>}> <Suspense fallback={<div>Loading...</div>}> <DataComponent /> <DataComponent /> </Suspense> </Suspense> </div> </div> ); ); } } const root = createRoot(document.getElementById('root')); const root = createRoot(document.getElementById('root')); root.render(<App />); root.render(<App />); 💼 Assets Loading React 19 has a feature where Assets Loads Auto in the background so websites work faster and look better! It starts loading pictures and other stuff for the next page while you're still looking at the current one. This means when you click to go to a new page, it shows up super fast! Have you ever seen a website that looks weird for a split second when it first loads? Like the words are in the wrong place or the colors are all mixed up? React 19 fixes this too. It makes sure everything looks just right before showing it to you. Code Example: Concurrent Rendering Code Example: Concurrent Rendering import React, { useState, Suspense } from 'react'; import React, { useState, Suspense } from 'react'; import { createRoot } from 'react-dom/client'; import { createRoot } from 'react-dom/client'; const SlowComponent = React.lazy(() => import('./SlowComponent')); const SlowComponent = React.lazy(() => import('./SlowComponent')); function App() { function App() { const [show, setShow] = useState(false); const [show, setShow] = useState(false); return ( return ( <div> <div> <button onClick={() => setShow(true)}>Show Slow Component</button> <button onClick={() => setShow(true)}>Show Slow Component</button> <Suspense fallback={<div>Loading...</div>}> <Suspense fallback={<div>Loading...</div>}> {show && <SlowComponent />} {show && <SlowComponent />} </Suspense> </Suspense> </div> </div> ); ); } } const root = createRoot(document.getElementById('root')); const root = createRoot(document.getElementById('root')); root.render(<App />); root.render(<App />); This way, the website can work on loading stuff in the background without bothering you while you're using it.
