Angular Material: 我需要导入每个卡片组件吗

Question

如果我想使用 Material 卡片组件。

'mat-card-actions' is not a known element:
'mat-card-content' is not a known element:
'mat-card-title' is not a known element:
'mat-card-header' is not a known element:
'mat-card' is not a known element:

需要一一导入吗？

Answer 1

是的，为了 Angular 的 tree-shaking。顺便说一句，你可以只在一个文件中创建一个数组并导入数组，然后将其传播到导入中：

FILE 1-- -- -- -- -- -- -
import {
  lib
} from './file'

@NgModule()
export class App {
  ...
  ...
  imports: [
    ...lib
  ]
}



FILE 2-- -- -- -- -- -- -
import { ...
} from '...'

export const lib = [All_Components]

Answer 2

只需要导入模块即可。

import {MatCardModule} from '@angular/material/card';
