Install

npm install ngx-mat-filter

Choose the version corresponding to your Angular version:

Angular	Angular Material	ngx-mat-filter
9	9	1.x+

Add needed package to NgModule imports:

import { NgxMatFilterModule } from 'ngx-mat-filter';

@NgModule({
  ...
  imports: [NgxMatFilterModule,...]
  ...
})

Usage

Add component to your page:

<ngx-mat-filter [worker]="worker" [fields]="fields"></ngx-mat-filter>

Setup Worker:

constructor() {
  this.worker = new NgxMatFilterWorker<Product>();
}

Setup fields:

this.fields = [
  createTextField({
    key: 'name',
    name: 'Product Name'
  })
];

For Select, Multi-Select and Autocomplete you need to define options:

this.fields = [
  createSelectField({
    key: 'material',
    name: 'Material',
    options: [
      { id: 1, name: 'Wood' },
      { id: 2, name: 'Metal' }
    ]
  })
];

As you see, we have an array options with id and name. If you make an order with this field, it will not work well. So you have to add sortKey to specify which property will be sorted.

this.fields = [
  createSelectField({
    key: 'material',
    name: 'Material',
    options: [
      { id: 1, name: 'Wood' },
      { id: 2, name: 'Metal' }
    ],
    sortKey: 'materialName'
  })
];

Initialize data:

this.worker.setData(this.items);
this.worker.update();

Data change:

this.worker.dataChange.subscribe((data: Product[]) => {
  //filtered data
});

Destroy worker:

ngOnDestroy() {
  this.worker.destroy();
}
