Modern frontend development with React, Next.js, and TypeScript
Explore the benefits of using custom components over traditional CSS classes and stylesheets in Vue and React. Understand how encapsulation, state management, and type safety enhance your web development process.
Deploying a NestJS API to production often triggers CORS errors—like “No ‘Access-Control-Allow-Origin’ header is present”—when your frontend or third-party clients live on a different domain. Using app.enableCors() with a secure configuration—restricting origins via an environment-driven whitelist, specifying allowed methods, and enabling credentials only when needed—ensures your API remains both accessible and protected.
Learn how to build a type-safe authentication system in Nuxt 3 using composables and Pinia, with TypeScript ensuring robust, scalable code. This tutorial walks you through creating a reusable useAuth composable that’s SSR-friendly and easy to integrate.
Solving the 'Cannot Use Import Statement Outside a Module' Error in NestJS with TypeORM
Struggling to inject a service from another module in your NestJS app? This guide simplifies the process, solving errors like Nest can't resolve dependencies. Learn how to export a service (e.g., UsersService), import its module into another (like AuthModule), and inject it seamlessly for modular, scalable applications. Follow clear steps and avoid pitfalls like missing exports or circular dependencies to keep your project running smoothly.
Learn the key differences between Middleware, Interceptors, and Exception Filters in NestJS. This guide breaks down how each works, when to use them, and how they can be combined to build clean, maintainable APIs.
Learn how to securely manage PostgreSQL connections in your NestJS app by using environment variables with @nestjs/config. This guide walks you through setting up a .env file, dynamically injecting values into TypeOrmModule, and validating your config with joi—all while avoiding hardcoded credentials and ensuring a clean, scalable setup.
NestJS uses interfaces for type safety and DTOs for runtime validation and transformation. While interfaces vanish at compile time, DTOs—enhanced by class-transformer—ensure clean, secure API data handling. Used together, they create robust and maintainable code.
Discover the similarities between beekeeping and Magento's Dependency Injection system as we delve into virtual types and types, serving as an allegory to illustrate the complexities of Magento's DI in a beekeeping e-commerce scenario.
Learn when to use composables and Pinia stores in Nuxt/Vue 3 and how to manage large datasets with strategies like pagination, infinite scrolling, and time-based filtering.
Learn how to handle "No metadata found" errors in TypeORM, focusing on resolving dependency issues when entities are specified explicitly.
Elevate your MUI theme customization with TypeScript. Learn to create type-safe custom component variants and themes with predefined styles, complete with TypeScript adjustments for rigorous type-checking and IntelliSense support.
Dive deep into the MUI type system with this developer-centric guide. Understand how to effectively utilize `StandardProps`, `React.HTMLAttributes`, `SxProps`, `ContainerClasses`, and `ComposedStyleFunction` with practical code examples, particularly focusing on the Typography component in MUI.
