ngx-duration-picker

ngx-duration-picker screenshot

A reusable Angular duration-picker component that works with ISO_8601 durations.

Requires Bootstrap, css only (no Bootstrap JS or jQuery needed).

DEMO

Installation

  • Run:

npm install --save ngx-duration-picker

  • Then in your app.module.ts add DurationPickerModule between your imports:
@NgModule({
  declarations: [...],
  imports: [
    DurationPickerModule,
    ...
  ],
  providers: [...],
  bootstrap: [AppComponent]
})
export class AppModule { }

Local development

  • On one terminal tab run ng build ngx-duration-picker --watch. This will build the library sources (projects/ngx-duration-picker/*) and watch for changes.

  • On another terminal tab run ng serve to serve the demo app (src/*) and play with it.

Usage

<ngx-duration-picker [(value)]="myDuration"></ngx-duration-picker>

where myDuration will be the variable where the output is stored, you can also pass an initial value.

Watch for changes

if you need to perform some operations each time the bound variable changes, you can use (valueChange):

<ngx-duration-picker [(value)]="myDuration" (valueChange)="doSomeStuff()">

you can pass specify some options by binding [options] to your configuration object:

<ngx-duration-picker [(value)]="myDuration" [options]="{ showWeeks: false }">

Available options

zeroValue
