State Management with Pinia Store in Vue 3

Learn to implement robust state management in Vue 3 applications using Pinia. Define state, getters, and actions for a global data store.

Reusable Logic with Vue 3 Composables

Create a custom composable function in Vue 3's Composition API to encapsulate and reuse reactive stateful logic across multiple components.

Dynamic Components with Vue 3's `is` Attribute

Render different components dynamically based on data using Vue 3's special `is` attribute, ideal for tabbed interfaces or wizards.

Creating a Reusable Modal Component with Teleport

Build a flexible and accessible modal dialog in Vue 3 using the <Teleport> component to render content outside the current component's DOM tree.

Custom `v-model` for Form Input Components

Implement the `v-model` directive on a custom Vue 3 component to create reusable and convenient form input elements with two-way data binding.

Centralized API Request Handling with Axios Interceptors

Efficiently manage API requests in JavaScript by using Axios interceptors to add common headers, handle errors, and refresh tokens globally.

Simple API Proxy with Node.js/Express to Hide API Keys

Create a secure Node.js/Express API proxy to forward requests, preventing sensitive API keys from being exposed in client-side code.

Handling Abortable API Requests with `AbortController`

Learn to cancel pending Fetch API requests in JavaScript using `AbortController` to improve performance and user experience in dynamic web applications.

Executing Parallel and Sequential Dependent API Calls

Master fetching data from multiple API endpoints by executing requests in parallel using `Promise.all` and sequentially with `async/await` for dependent operations.

Implement Server-Side Rate Limiting for API Endpoints

Protect your API endpoints from abuse, brute-force attacks, and DoS by implementing server-side rate limiting using the `express-rate-limit` middleware in Node.js.

Handle API Rate Limiting with Exponential Backoff

Implement a robust retry mechanism with exponential backoff for API calls, gracefully handling rate limits and transient errors to ensure successful data retrieval.

Obtain OAuth 2.0 Client Credentials Token

Securely acquire an OAuth 2.0 access token using the client credentials flow, ideal for server-to-server API integrations without user interaction.
