Angular: Build dynamic and powerful web applications
Angular is a popular open-source JavaScript framework maintained by Google, used for building dynamic and high-performance web applications. It provides a robust structure for developing complex single-page applications (SPAs) and progressive web apps (PWAs), offering features like data binding, dependency injection, and component-based architecture. Hiring a skilled Angular freelancer can significantly accelerate your web development projects and deliver a seamless user experience.
What to look for in an Angular freelancer
When searching for an Angular freelancer, consider their experience with different versions of Angular (AngularJS, Angular 2+, and the latest versions). Look for proficiency in TypeScript, the primary language used with Angular, and experience with related technologies like RxJS (Reactive Extensions for JavaScript) and NgRx (state management library). A strong understanding of web fundamentals (HTML, CSS, JavaScript) is crucial, as is experience with testing frameworks like Jasmine and Karma.
Main expertise areas within Angular
Angular development encompasses various specialisations. Some key areas to inquire about include:
- Component development and architecture
- State management (using NgRx or similar libraries)
- Routing and navigation
- Form handling and validation
- API integration and data fetching
- Testing and debugging
- Performance optimisation
- Progressive web app (PWA) development
- Server-side rendering (SSR) with Angular Universal
