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 THE HEART OF
ANGULAR'S PERFORMANCE
Let's kick things off with one of Angular's most
crucial performance features change detection.
Think of change detection as Angular's way of
keeping your application's data and view in sync.
By default, Angular checks every component in
your application whenever any data changes. While
thorough, this can be overkill for larger
applications. Here's where change detection
strategies come into play a) Default Strategy
Angular checks the entire component tree for
changes. It's simple but can be inefficient for
complex apps. b) OnPush Strategy This is where
the magic happens. By using OnPush, you're
telling Angular, "Hey, only check this component
if its input properties change or an event occurs
within it." This can significantly reduce the
number of checks Angular performs.
5LET'S SEE A QUICK EXAMPLE

- RE GIVING ANGULAR A HELPING HAND IN OPTIMIZING
ITS WORK. - 2. AOT Compilation Speeding Up Your App's
Startup - Next up, let's talk about Ahead-of-Time (AOT)
compilation. This is like giving your Angular app
a turbo boost right from the start. - Here's the deal By default, Angular uses
Just-in-Time (JIT) compilation, which compiles
your templates in the browser at runtime. AOT, on
the other hand, compiles your templates during
the build process. - BENEFITS OF AOT
- FASTER RENDERING YOUR APP LOADS AND RENDERS MORE
QUICKLY. - SMALLER FILE SIZE THE COMPILER IS NOT SHIPPED
WITH YOUR APP. - EARLIER ERROR DETECTION COMPILATION ERRORS ARE
CAUGHT DURING DEVELOPMENT.

3. LAZY LOADING AND CODE SPLITTING A DIET PLAN
FOR YOUR APP IMAGINE IF YOU COULD LOAD ONLY THE
PARTS OF YOUR APP THAT THE USER NEEDS RIGHT NOW.
THAT'S EXACTLY WHAT LAZY LOADING DOES! IT'S LIKE
SERVING YOUR APP IN BITE-SIZED CHUNKS RATHER THAN
FORCING USERS TO DIGEST THE WHOLE THING AT ONCE.
8HERE'S HOW YOU CAN IMPLEMENT LAZY LOADING FOR A
FEATURE MODULE
THIS TELLS ANGULAR TO LOAD THE FEATUREMODULE ONLY
WHEN A USER NAVIGATES TO THE 'FEATURE' ROUTE.
IT'S A GAME-CHANGER FOR LARGER APPLICATIONS WITH
MULTIPLE COMPLEX FEATURES.
94. MEMORY LEAK PREVENTION KEEPING YOUR APP LEAN
AND CLEAN MEMORY LEAKS ARE THE SILENT
PERFORMANCE KILLERS. THEY OCCUR WHEN YOUR
APPLICATION HOLDS ONTO DATA IT NO LONGER NEEDS.
IN ANGULAR, A COMMON CULPRIT IS FORGETTING TO
UNSUBSCRIBE FROM OBSERVABLES.
10HERE'S A TIP USE THE TAKEUNTIL OPERATOR WITH
RXJS TO AUTOMATICALLY UNSUBSCRIBE WHEN A
COMPONENT IS DESTROYED
11- 5. ANGULAR UNIVERSAL SERVING UP SERVER-SIDE
RENDERING - LAST BUT NOT LEAST, LET'S TALK ABOUT ANGULAR
UNIVERSAL. THIS POWERFUL FEATURE ALLOWS YOU TO
RUN YOUR ANGULAR APP ON THE SERVER, PRE-RENDERING
YOUR PAGES AND SERVING THEM TO CLIENTS. IT'S LIKE
HAVING A SUPER-EFFICIENT WAITER WHO PREPARES YOUR
MEAL BEFORE YOU EVEN SIT DOWN AT THE RESTAURANT! - BENEFITS OF ANGULAR UNIVERSAL
- IMPROVED SEO SEARCH ENGINES CAN CRAWL YOUR
CONTENT MORE EFFECTIVELY. - FASTER INITIAL LOAD USERS SEE CONTENT ALMOST
INSTANTLY. - BETTER PERFORMANCE ON MOBILE AND LOW-POWERED
DEVICES.
