Seamless upgrade to angular 5

Seamless upgrade to angular 5

The team at Google released the new version of angular that is Angular 5.0.0, pentagonal-donut. The main three insights that came up from using angular 5 are that it is faster, smaller, and easier to use. To implement these updates it is required to make a few changes in an existing website however migrating to angular 5 would be impactful in terms of performance, features, and enhancements.

Changes that would be encountered during the migration:

  • Migration from Angular JS to Angular 5 – Renovation of the application is required as there is a change in the architecture from MVC to Service/ Controller and change in the code from JavaScript to Typescript. However the advantages would be that the application would be feature-packed, much faster, code generated would be lesser which would accelerate the application development process.
  • Migration from Angular2, 3, 4 to 5 – Angular 5 shouldn’t be misinterpreted to be an entirely new framework. It is just Angular 4 with a few additional features and bug fixes from the previous versions in order to enhance the performance.

In case if you have an existing application running on angular 2,3 or 4 then upgrading to angular 5 would be a cakewalk. If you have an existing website running on angular js then it would require a renovation however it would be worth the benefits and enhancements post the upgrade.

Upgrading to Angular 5 is beneficial for the following reasons:

  • Build Optimizer

This optimizer is designed to make applications smaller by removing unnecessary codes. We would be using the build optimizer which would remove angular decorators from the application’s runtime thereby reducing the bundle size and increasing the application speed.

  • Angular Universal State Transfer API and DOM Support

We use Angular universal state transfer API that provides server-side rendering of angular applications that boosts the performance of the applications. version 5 introduces a new module called “ ServerTransferStateModule” to optimize the process of capturing the data over HTTP.

  • AOT compiler

The ahead of time compiler has fewer asynchronous requests, faster rendering, and the AOT compiler can also detect template errors before runtime.

  • Pipes

We develop applications using the internationalized Number, Date, and Currency pipes that have been introduced in angular which increase standardization across browsers and eliminate the need for polyfills.

  • Preserve Whitespace

Usually, tabs, news lines, and spaces in your templates get recreated and included in your build by the compiler. Using Angular 5 we provide options where you can choose whether or not to preserve whitespaces coming from your components.

  • Modular

We practice modular development approaches allowing our developers to organize codes into independent chunks or modules that make maintenance, testing, up-gradation, and adding new features more convenient


The insights-driven angular 5 is packed with some amazing features that make an application faster, lighter, and easier to use. Hence it is recommended that older versions of angular need to be upgraded to angular 5 in order to release new features and performance enhancements to your applications.
