Schematics

Angular schematics is a workflow tool that allows you generate component, modules, and resolve dependency issues. The main goal of the schematics is ease of use and development in angular environment.

EJ2 Slider supports Angular schematic’s module injection, component generation, automation dependency installation, styles imports, etc.

Getting started

Note: Angular schematics supports only from the Angular CLI v6. So, check your version by running ng --version. If it is below version 6, update your CLI by running the following command: npm install -g @angular/cli.

In order to work with Angular schematics, create an Angular CLI application. Run the following command to create a CLI application.

ng new angular-application

After running the above command and all the dependency modules installed, we can generate EJ2 Slider component using schematics.

Dependency and Module injection using Schematics

Using schematics, we can perform dependency and module injection of the EJ2 inputs package @syncfusion/ej2-angular-inputs automatically. Run the following command in the root of the application.

ng add @syncfusion/ej2-angular-inputs --modules=slider

If we ignore the --modules=slider flag, it will import all the modules present (ColorPickerModule, UploaderModule, etc.) inside @syncfusion/ej2-angular-inputs package.

The above command will do the following,

  • Installs the @syncfusion/ej2-angular-inputs package, and add an entry in package.json file.
  • Imports the SliderModule module in the app.module.ts, and add an entry in the import property of the @NgModule decorator.

Component generation using Schematics

Angular Schematics can be used to generate component, module file, etc. In the same way, Slider components can also be generated.

By using the Schematics to generate EJ2 Slider, the time for configuring components is significantly reduced and it is made ready for development immediately. To generate EJ2 Slider component with specific features, refer to the following table.

The general syntax for the ng generate command is ng generate @syncfusion/<component-package-name>:<componentName-featureName> --name=<your-desired-name>

Feature Name Schematics command
Default Slider ng generate @syncfusion/ej2-angular-inputs:slider-default --name=default-slider
MinRange Slider ng generate @syncfusion/ej2-angular-inputs:slider-minrange --name=minrange-slider
Range Slider ng generate @syncfusion/ej2-angular-inputs:slider-range --name=range-slider
Ticks Slider ng generate @syncfusion/ej2-angular-inputs:slider-ticks --name=ticks-slider
Limits Slider ng generate @syncfusion/ej2-angular-inputs:slider-limits --name=limits-slider
Vertical Slider ng generate @syncfusion/ej2-angular-inputs:slider-vertical --name=vertical-slider

The above commands will do the following,

  • Generate the Slider with specific features mentioned in the src/app with folder name of the name property passed.
  • Import the generated component into the app.module.ts file, and add an entry in the declarations array in the @NgModule decorator.

Note: It is not required to run the above commands only after the ng add @syncfusion/ej2-angular-inputs, but it is required to have @syncfusion/ej2-angular-inputs installed.
