Correct way of importing and using lodash in Angular

Question

I used to be able to use a lodash method in Angular by an import statement that looked like the following:

import {debounce as _debounce} from \'lodash\';
         


        

Answer 1

Importing lodash or any javascript library inside angular:

step-1: Install the libarary(lodash)

npm i --save lodash

step-2: import it inside the component and use it.

import it as follow:

import 'lodash';

declare var _:any;

or

import * as _ from 'lodash';

Step-3: Install type definitions for Lo-Dash (it's optional)

npm install --save-dev @types/lodash

see the example if you still have doubts

import { Component, OnInit } from '@angular/core';
// import * as _ from 'lodash';
import 'lodash';

declare var _:any;

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  title = 'test-lodash';

  ngOnInit() {
    console.log(_.chunk(['a', 'b', 'c', 'd'], 2)); //lodash function
    console.log(_.random(1, 100)); //lodash function
  }

}
