新功能

date-fns 1.x 不支持日期的反格式化，相关 issue 有：#4028 #3976 #2492 #4101。
date-fnx 2.x 已支持该功能。

date-fns 1.x does not support date parsing. Related issues are: #4028 #3976 #2492 #4101. date-fnx 2.x already supports [this feature] (https://date-fns.org/v2.9.0/docs/parse)

如何实现

由于 angular 的日期格式与 date-fns 的日期格式并不兼容。因此反格式化功能只有在用户引入了 date-fns 才能使用。

Since angular's date format and date-fns' date format are not compatible. Therefore, the parsing feature could only be supported when the user provides date-fns.

Breaking Change

我们推荐用户使用 date-fns 2.x 的新的 format 格式。同时也提供配置项将 1.x format 转为 2.x format，新旧 format 的对比参照这里。

We recommend that users use the new format of date-fns 2.x, and we also provide configuration items to convert 1.x format to 2.x format. For a comparison of the old and new formats, refer to here.

@NgModule({
  ...
  imports     : [ NgZorroAntdModule ],
  providers: [
    { provide: NZ_DATE_LOCALE, useValue: enUS },
    // Set `dateFnsFormatConvert ` to convert format from v1 to v2
    { provide: NZ_DATE_FNS_COMPATIBLE, useValue: true }
  ]
})
export class AppModule { }
