3INTRODUCTION
Hey there, tech enthusiasts and Angular
enthusiast! Today, we're diving deep into the
world of Angular performance optimization.
Whether you're a developer or just starting your
journey with this powerful framework, this guide
will help you supercharge your Angular
applications. At Softradix, we've tackled
numerous Angular projects, and we're excited to
share our insights with you.
4CHANGE DETECTION STRATEGIES
- Angular's change detection mechanism is at the
core of its performance. Understanding and
optimizing this process can significantly improve
your application's speed. Lets follow angular
development agency in USA steps - Default vs OnPush Strategy
- Default Angular checks every component in the
component tree. - OnPush Only checks components when their inputs
change or events occur. - Implementing OnPush
5- Benefits of OnPush
- Reduces the number of checks Angular performs
- Improves performance in large applications
- Encourages immutable data structures
- Best Practices
- Use immutable objects or observables with OnPush
- Manually trigger change detection when needed
using ChangeDetectorRef - AOT (Ahead-of-Time) Compilation Benefits
- AOT compilation can significantly improve your
application's startup time and overall
performance. - What is AOT?
- Compiles Angular templates to JavaScript at build
time, rather than at runtime
6- Benefits
- Faster rendering No need to compile templates at
runtime - Smaller file size Compiler is not shipped with
the application - Earlier error detection Compilation errors are
caught during build - Enabling AOT
- Considerations
- Longer build times
- Some limitations on dynamic code generation
- Lazy Loading and Code Splitting
- Lazy loading helps to reduce the initial bundle
size, improving the application's startup time.
7- Implementing Lazy Loading
- const routes Routes
- path 'customers', loadChildren () gt
import('./customers/customers.module').then(m gt
m.CustomersModule) -
- Benefits
- Reduces initial load time
- Improves performance on low-bandwidth networks
- Better resource utilization
- Best Practices
- Group related functionality into feature modules
- Lazy load feature modules that aren't immediately
necessary
8- Memory Leak Prevention
- Memory leaks can severely impact performance over
time. Preventing them is crucial for long-running
applications. - 4.1 Common Causes
- Unsubscribed Observables
- Detached DOM elements
- Circular references
- Prevention Techniques
- Always unsubscribe from Observables
9- Use async pipe in templates when possible
- Avoid storing references to DOM elements
- Use WeakMap for caching objects
- Tools for Detection
- Chrome DevTools Memory tab
- Angular DevTools
- ngx-reactive-memory-leak-hunter
- Angular Universal for Server-Side Rendering
- Angular Universal can significantly improve
perceived performance and SEO. - What is Angular Universal?
- Server-side rendering (SSR) for Angular
applications
10- Benefits
- Faster initial page load
- Improved SEO
- Better performance on low-powered devices
- Implementation
- Considerations
- Increased server load
- Complexity in handling browser-specific code
11Conclusion
Optimizing Angular applications is an ongoing
process. By implementing these strategies -
fine-tuning change detection, utilizing AOT
compilation, implementing lazy loading,
preventing memory leaks, and considering
server-side rendering - you can significantly
improve your application's performance. Remember,
the key is to profile your application, identify
bottlenecks, and apply these optimizations where
they'll have the most impact.
