+
+# @nrwl/angular:component
+
+Generate an Angular Component.
+
+## Usage
+
+```bash
+nx generate component ...
+```
+
+By default, Nx will search for `component` in the default collection provisioned in `workspace.json`.
+
+You can specify the collection explicitly as follows:
+
+```bash
+nx g @nrwl/angular:component ...
+```
+
+Show what will be generated without writing to disk:
+
+```bash
+nx g component ... --dry-run
+```
+
+## Options
+
+### name (_**required**_)
+
+Type: `string`
+
+The name of the component.
+
+### changeDetection
+
+Alias(es): c
+
+Default: `Default`
+
+Type: `string`
+
+Possible values: `Default`, `OnPush`
+
+The change detection strategy to use in the new component.
+
+### displayBlock
+
+Alias(es): b
+
+Default: `false`
+
+Type: `boolean`
+
+Specifies if the style will contain `:host { display: block; }`.
+
+### export
+
+Default: `false`
+
+Type: `boolean`
+
+Specifies if the component should be exported in the declaring NgModule. Additionally, if the project is a library, the component will be exported from the project's entry point (normally `index.ts`).
+
+### flat
+
+Default: `false`
+
+Type: `boolean`
+
+Create the new files at the top level of the current project.
+
+### inlineStyle
+
+Alias(es): s
+
+Default: `false`
+
+Type: `boolean`
+
+Include styles inline in the component.ts file. Only CSS styles can be included inline. By default, an external styles file is created and referenced in the component.ts file.
+
+### inlineTemplate
+
+Alias(es): t
+
+Default: `false`
+
+Type: `boolean`
+

+
+### path (**hidden**)
+
+Type: `string`
+
+The path at which to create the component file, relative to the current workspace. Default is a folder with the same name as the component in the project root.
+
+### project
+
+Type: `string`
+
+The name of the project.
+
+### selector
+
+Type: `string`
+
+The HTML selector to use for this component.
+
+### skipSelector
+
+Default: `false`
+
+Type: `boolean`
+
+Specifies if the component should have a selector or not.
+
+### skipTests
+
+Default: `false`
+
+Type: `boolean`
+
+Do not create "spec.ts" test files for the new component.
+
+### style
+
+Default: `css`
+
+Type: `string`
+
+Possible values: `css`, `scss`, `sass`, `less`, `none`
+
+The file extension or preprocessor to use for style files, or 'none' to skip generating the style file.
+
+### type
+
+Default: `component`
+
+Type: `string`
+
+Adds a developer-defined type to the filename, in the format "name.type.ts".
+
