Angular

PhpStorm provides predefined live templates for creating Angular components, such as a-component, a-component-inline, and a-component-root. For more information about live templates, refer to Live templates.

To view a full list of predefined templates, open the Settings dialog (CtrlAlt0S), go to Editor | Live Templates, and expand the Angular node.

1. In the editor, press Ctrl0J, select the appropriate template (for example, a-component) from the list, and then press Enter.

2. PhpStorm generates a component stub, places the caret at a field with canvas, and waits for you to specify the component name there. As you type the component name, the name of the selector and the template URL are filled in automatically in accordance with the Angular Style Guide.

In PhpStorm, you can create a bunch of files for an Angular component in one action and even place them all in a separate folder. To do that, you need to use a file template with several child templates. When you create a file from the parent template, the related files from the child templates are generated automatically. For more information, refer to Templates with multiple files.

Suppose you want to create an example folder with a bunch of component files, for example, example.component.ts for logic, example.component.html for the template, and example.component.css for styles. You can create a file template with two parent templates so all the three files will be generated at once and placed in a separate folder.

1. In the Settings dialog (CtrlAlt0S), select Editor | File and Code Templates.

2. First create a template for a TypeScript component file:

   1. In the Files tab, click the Add button () on the toolbar. A new, Unnamed, template is added to the list.

   2. In the right-hand pane, specify the template name, let it be Angular Component, and component.ts as the file extension.

   3. In the File name field, type $NAME/$NAME.

   4. Optionally, add a code template, for example:

      **
       * Created by ${USER} on ${DATE}
      */
      
      import { Component } from '@angular/core';

   

   Click Apply.

3. Create a child template for the related HTML file:

   1. Select the parent template Angular Component and click the Create Child Template File button on the toolbar. A child template is added below the Angular Component template.

   2. In the right-hand pane, type $NAME/$NAME in the File name field and specify the component.html extension.

   

   Click Apply.

4. Create a child template for the related Style Sheet.

   1. Select the parent template Angular Component and click on the toolbar. A child template is added below the Angular Component template.

   2. In the right-hand pane, type $NAME/$NAME in the File name field and specify the component.css extension.

5. Click OK to save the templates.

6. Create the component files.

   From the context menu of the folder where you want to store the component files, select New | Angular Component. In the dialog that opens, specify the name that will be used for the folder and for the component files in it (example in this example).

The Extract Angular component refactoring works by running ng generate component, taking schematic preferences inside your angular.json file into account.

1. In an HTML template file, select the code fragment that you want to extract into an Angular component.

2. From the context menu of the selection, choose Refactor | Extract Component.

   Alternatively, press CtrlAltShift0T and select Extract Component from the Refactor This popup.

3. In the dialog that opens, specify the name of the new component.

   • Press CtrlAltHome.

   • Select Navigate | Related Symbol from the main menu.

   • Right-click any area in the editor and select Go To | Related Symbol.

   In a TypeScript component file, the popup also lists all the symbols that were imported into this file.

   

2. To open a file, select it and press Enter. Alternatively, use the numbers associated with each file type:

   1. The TypeScript file with the component class

   2. Template

   3. Tests

   4. Styles

1. Select File | New from the main menu or press AltInsert in the Project tool window, and then select Angular Dependency.
