Using full featured Datatables Plugin with Angular 6

Question

I am trying to add Datatables plugin (datatables.net) facility with my angualar 6 project. I am not sure how should I include the necessary css, js and other required files

Answer 1

Just add your .css files in styles section and .js files in Scripts section, in angular(-cli).json. I think this would resolve your issues.

Answer 2

By just watching the question and the answer from @dickrichie, I still had an error:

ERROR in node_modules/angular-datatables/src/angular-datatables.directive.d.ts(1
,23): error TS2688: Cannot find type definition file for 'datatables.net'.
node_modules/angular-datatables/src/angular-datatables.directive.d.ts(15,16): er
ror TS2503: Cannot find namespace 'DataTables'.
node_modules/angular-datatables/src/angular-datatables.directive.d.ts(27,25): er
ror TS2503: Cannot find namespace 'DataTables'.

I was missing the two last install steps to make Datatables.net works with Angular 6.

npm install jquery --save
npm install datatables.net --save
npm install datatables.net-dt --save
npm install angular-datatables --save
npm install @types/datatables.net --save-dev

Then follow the message from @dickrichie to edit angular.json and app.module.ts files. Now any table tag where you add "datatable" should work.

-- EDIT

The first part of that answer is with using angular-datatables, but as @fahimuddin asked in fact how to do that without that package, I tried differently.

So no need to install the last two packages, the angular.json looks the same as in @dickrichie answer and in a component I just added before the @Component:

declare var $: any;

And then use directly jQuery and Datatables in ngOnInit():

$('#your-datatable-id').DataTable();

It works and nobody's complaining but I'm not sure if it's a good practice? (And as in my case I'm trying to do an Angular-Electron app, it's still not working in Electron, it wasn't working with angular-datatable neither, but that's another problem!)

Answer 4

Adding DataTablesModule.forRoot() in imports of appmodule.ts works! Or if you are using a lazy loading remember to put it in every module.ts

Answer 5

You need to do changes into angular.json file:

"styles": [
    ...
    "node_modules/datatables.net-bs4/css/dataTables.bootstrap4.min.css",
    ...
],
"scripts": [
    ...
    "node_modules/datatables.net/js/jquery.dataTables.js",
    "node_modules/datatables.net-bs4/js/dataTables.bootstrap4.min.js"
    ...
]

And the same way for extensions plugins.

Answer 6

use angular data tables in Angular 6 angular-datatables

You need to install its dependencies before getting the latest release using NPM:

npm install jquery --save
npm install datatables.net --save
npm install datatables.net-dt --save
npm install angular-datatables@6.0.0 --save
npm install @types/jquery --save-dev
npm install @types/datatables.net --save-dev

angular.json

Import the DataTablesModule in app.module.ts

import { DataTablesModule } from 'angular-datatables';

imports: [
    DataTablesModule
  ],

my datatableslibrary.ts

import { Component, OnDestroy, OnInit } from '@angular/core';
import { Http, Response } from '@angular/http';
import { Subject } from 'rxjs';
import { HttpClient } from '@angular/common/http';
import { DataService } from '../data.service';

@Component({
  selector: 'app-datatableslibrary',
  templateUrl: './datatableslibrary.component.html',
  styleUrls: ['./datatableslibrary.component.css']
})
export class DatatableslibraryComponent implements OnInit, OnDestroy {

  users$: any[] = [];
  dtOptions: DataTables.Settings = {};
  dtTrigger: Subject<any> = new Subject();

  constructor(private http: HttpClient, private data: DataService) {
  }

  ngOnInit() {
    this.dtOptions = {
      pagingType: 'full_numbers',
      pageLength: 5,
      processing: true
    };
    this.data.getUsers().subscribe(data => {
      this.users$ = data;
      this.dtTrigger.next();
    });
  }

  ngOnDestroy(): void {
    this.dtTrigger.unsubscribe();
  }

}

my datatableslibrary.component.html

<table class="table table-striped table-bordered table-sm row-border hover" datatable [dtOptions]="dtOptions"
  [dtTrigger]="dtTrigger">
  <thead>
    <tr>
      <th>Name</th>
      <th>Email</th>
      <th>Website</th>
    </tr>
  </thead>
  <tbody>
    <tr *ngFor="let user of users$">
      <td>{{ user.name }}</td>
      <td>{{ user.email }}</td>
      <td>{{ user.website }}</td>
    </tr>
  </tbody>
