Make your life easier and migrate to Signals with Angular 17<\/h2>\n

In the first three parts of this series Angular Signals Part 1 \u2013 How-to Guide on Angular Signals<\/a>, Angular Signals Part 2 \u2013 How to combine Angular Signals and RxJS<\/a>\u00a0and Angular Signals Part 3 \u2013 What are the advantages of Signal Inputs<\/a> we looked at what Signals are, how to combine them with RxJS and what the advantages of Signal Inputs are. This time we want to show you how old Angular code can be easily migrated to Signals with the help of ngxtension so that you can take advantage of Signals as quickly as possible.<\/p>\n

In recent years, Angular has continued to evolve to provide developers with more powerful and efficient tools. An important step in this evolution is the introduction of Angular Signals in Angular 17, which allows developers to manage reactive state in a more intuitive and efficient way. However, the question for many is how to seamlessly migrate your legacy Angular code to Angular Signals without disrupting the development flow.<\/p>\n

This is where extensions come into play that simplify and accelerate this migration. In this article, we will introduce you to ngxtension and two extensions that helped us a lot during the migration and with which we were able to migrate to the new signal-based paradigm in an efficient and structured manner.<\/p>\n

Ngxtension<\/h2>\n

Ngxtension<\/a> is a framework and library for Angular that aims to simplify the development of Angular applications. It offers various extensions, utility functions and tools that make it easier to work with Angular components, services and modules. To use ngxtension in your projects, you can add it e.g. via the Angular CLI or install it with npm.<\/p>\n

Command for Angular CLI:<\/p>\n

ng add ngxtension<\/pre>\n
npm command:<\/p>\n
npm install ngxtension<\/pre>\n
Now that ngxtension is installed, let’s take a closer look at the migration of inputs and outputs. Manually migrating inputs and outputs to the new input()<\/code> and output()<\/code> functions can be a tedious and error-prone task. Fortunately, this process is almost completely automated through the use of ngxtension.<\/p>\n

Use ngxtension to migrate @Input to Signal Inputs<\/h2>\n
With Angular v17.1, Signal Inputs were released and have since allowed us developers to use more declarative and reactive code patterns. For this reason, ngxtensions publishes schematics that take over the code migration for us. Among other things<\/p>\n
