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.
