Deployment is an essential aspect of the application development process. It will help ensure a better user experience and optimal performance in production environments. Whether deploying to the cloud platform, a web server, or in a containerized environment, following best practices can help you avoid common pitfalls. Therefore, today, we will discuss some of the critical best practices for Angular app deployment that you should follow for successful deployment.
- AOT Compilation
Ahead-of-time compilation helps you pre-compile your Angular application during the build process, which allows you to produce more optimized JavaScript files that are smaller and faster to load.
- Enable Tree Shaking
Tree shaking is a process that eliminates unnecessary code from your application, making it smaller and faster. It will help significantly in reducing bundle size. Angular already incorporates this feature when building for production, but you only have to ensure that your imports are correctly structured.
- Lazy Loading of Modules
Lazy loading in Angular is a powerful technique that can significantly improve the performance of large applications. By Delaying the loading of specific components or modules until they are needed reduces the initial bundle size, resulting in faster load times and a better user experience. This is especially beneficial for applications with complex features or multiple pages.
- Utilize Angular Universal for Improved SSR
We all know that Single-page applications like Angular struggle with SEO, and search engine crawlers sometimes struggle with rendering client-side JavaScript. However, utilizing Angular Universal for server-side rendering helps solve this issue by pre-rendering the pages before sending them to the browser. SSR will help you improve your application's performance, especially on slower devices or networks, and ensure that search engines index your content correctly.
- Implement CDNs:
Content Delivery Networks can dramatically reduce users' time to load your Angular app. When you choose CDN for Angular app deployment, your application assets will be served from multiple locations worldwide, ensuring the user gets the content from the nearest server.
- Monitor and Optimize for Performance
Once your Angular app deployment is successfully completed, you should continuously monitor its performance using tools like Google Lighthouse, WebPageTest, or Chrome DevTools. These tools will offer various insights regarding performance bottlenecks and suggestions for improvement.
- Configure Caching
Leveraging browser caching is one of the simplest ways to boost your app’s speed. You can configure cache settings for static files (CSS, JavaScript, Images) so that re-visiting users don’t need to download them again.
Conclusion
The Angular app deployment process can be smooth and efficient when you follow best practices. By focusing on the above-mentioned best practices, you can ensure that your Angular applications perform well and provide a seamless user experience. But for more efficient and professional deployment, you should hire Angular developers to ensure your app is deployed appropriately and optimized for better performance.
