JAVASCRIPT Snippets.

OAuth 2.0 Client Credentials Flow for Server-to-Server Authentication

Securely obtain an access token using the OAuth 2.0 Client Credentials grant type in Node.js, ideal for server-to-server API integrations requiring programmatic access.

Efficiently Batching Multiple Independent API Requests

Learn how to use `Promise.all` to concurrently fetch data from multiple API endpoints, significantly improving load times and user experience for dashboard-like interfaces.

Handling API Versioning with Custom Accept Headers

Discover how to explicitly request a specific API version using custom `Accept` headers, a common and flexible strategy for integrating with evolving external APIs.

Global Theme Management with `useContext`

Learn to manage global themes (light/dark mode) in a React application using `useContext` to avoid prop drilling and provide state to deeply nested components.

Tracking Previous Prop or State with `usePrevious`

Create a custom React hook, `usePrevious`, to easily access the previous value of any prop or state variable, useful for comparing changes over renders.

Debouncing User Input with a `useDebounce` Hook

Implement a `useDebounce` custom hook in React to delay updating a value until a specified time has passed, optimizing performance for frequent input changes.

Dynamically Updating Document Title with `useEffect`

Use the `useEffect` hook in React to programmatically change the browser's document title based on component state or props, enhancing user experience.

Persisting React State with `useLocalStorage` Custom Hook

Build a `useLocalStorage` custom hook to automatically synchronize a React component's state with the browser's local storage, preserving data across sessions.

Managing Complex State with `useReducer`

Learn to manage complex application state more predictably than `useState` using React's `useReducer` hook, ideal for state transitions and multiple sub-values.

Optimizing Performance with `useCallback`

Learn to prevent unnecessary re-renders in child components by memoizing callback functions using React's `useCallback` hook, improving application performance.

Caching Expensive Computations with `useMemo`

Optimize React component performance by memoizing the result of expensive calculations using `useMemo`, preventing re-computation on every render.

Accessing DOM Elements with `useRef`

Learn how to directly interact with DOM elements or store mutable values without triggering re-renders using React's `useRef` hook.
