AngularJs Best Practices - Ongraph
- In a web app development environment, Angular has
established itself as the widely used framework
and its popularity graph is constantly rising
after the arrival of its much-awaited version
AngularJS 4.0. AngularJS is insanely fast, still
every Angular expert struggle with various issues
that directly claims to AngularJS performance
even though it has a lot of its own
optimizations. But there might be cases appear
where the incorrect use of AngularJS methods
restricts an application to stand in the market.
So, AngularJS performance optimization becomes an
important need of every Best AngularJS
Development Company expert. To improve the
AngularJS performance, you need to follow best
practices. Thats why we have listed 5 ways to
improve AngularJS performance in this blog.

1. Measure Application Structure (smaller bundles
faster applications)
- Measure the structure of your application to
ensure faster loading of your web app. By
performing standard practices of bundling, it is
easy to reduce the number of requests that the
browser needs to perform in order to deliver the
application requested by the user. In short, the
bundler receives as an input a list of entry
points and produces one or more bundles. This way
the browser can get the entire application by
performing only a few requests, instead of
requesting each individual resource separately.
As your application grows bundling everything
into a single large bundle would again be
counterproductive.

2. Ahead Of Time
Compile
- AOT is considered as a more appealing alternative
than JIT for production purpose. While coding,
the application still runs using the just-in-time
(JIT) compiler. But you should look to find how
you can integrate AOT. - Ahead-of-time vs Just-in-time
- The difference between AOT and JIT is a matter of
timing and tooling. The compiler runs once with
AOT at build time using one set of libraries,
whereas with JIT it runs every time for every
user at runtime using a different set of
libraries. - Why Do AOT Compilation?
- Compilation uncovers many component-template
binding errors. JIT compilation discovers them at
runtime, which is late in the process. The
ahead-of-time (AOT) compiler can catch template
errors early and improve performance by compiling
at build time.

3. Stay Up To Date
- Every new version of technology comes with many
reassessed and refined concepts. After the
release of Angular 2, the next big update for
Angular is now available Angular 4. Now
AngularJs Consulting can be used in many
different programming languages like Dart,
Typescript or ECMAScript 5 among others. You must
adopt a new version of the framework to stay up
to date. - In the new release, some major improvements and
functionality are added to enhance the
application performance. Angular 4 make
applications smaller and faster. Angular 4 offers
around 49.78 reduction in main bundle size in
comparison to Angular 2. Its much quicker to
complete while ensuring smaller loading time. New
updates with improved functionality offer more
efficient migration along with more added
features. - Known Issues that Angular 4 addresses
- The primary goal of version 4 was to make Angular
compatible with TypeScripts strictNullChecks
setting while enabling it a more restrictive
subset of types to be mandated. More work has
been done to allow it function properly in all
use cases, hence the company intentionally made
4.0 incompatible with the strictNullChecks
setting to escape breaking apps that would
otherwise eagerly adopt this TypeScript mode when
the proper support lands in 4.1 (tracking issue
is 15432).

4. Lazy Load
- Lazy loading ensures faster performance and
better user experience. A large-scale application
will contain lots of feature modules which
require not be stacked at the same time.
Lessening the size of a bundle when the app loads
initially significantly increase the app load
times thus improving the user experience. - Once you work out the functional areas of an
application, its overall size will grow. Sooner
or later you come to a point where the
application starts to stack gradually. At that
time, Lazy loading helps to reduce the initial
load time for a medium as well as vast
applications. - Lazy Loading to meet the following application
requirements - Load application areas only on user request
- Faster load time for users that only visit
certain (priority) areas - Expand application features without increasing
the size of the initial load bundle

5. Polyfill
Responsibly
- Create polyfill builds based on the clients
browser and serve only whats needed. This allows
you to write modern JavaScript without worrying
too much (you should still do due diligence)
about browser support as well as not penalizing
modern browsers with unnecessary polyfills.
