Hello, I am new to ng2 and have a question that may seem obvious to some. I recently installed the jstree library using npm in my angular-cli application by running the command npm i jstree --save. Following this, I also installed the types for jstree with npm i @types/jstree --save-dev as part of the setup process. However, when I tried to use it, I encountered difficulties. Can someone please guide me on how to properly utilize this third-party library with TypeScript?
To successfully make it work, I followed these steps starting with a new cli application.
npm install --save jquery jstree
npm install --save-dev @types/jquery @types/jstreeAfter that, I made changes to the angular.json file or if using an older version of angular-cli, edited the angular-cli.json file. Added
"../node_modules/jstree/dist/themes/default-dark/style.min.css"I then included the following items in the scripts property array:
"../node_modules/jquery/dist/jquery.min.js",
"../node_modules/jstree/dist/jstree.min.js"
Updated src/app/app.component.html with:
<div id="foo">
<ul>
<li>Root node 1
<ul>
<li>Child node 1</li>
<li><a href="#">Child node 2</a></li>
</ul>
</li>
</ul>
</div>
Further updates were made in src/app/app.component.ts:
import { Component, OnInit } from '@angular/core';
declare var $: any;
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
ngOnInit(): void {
$('#foo').jstree();
}
}
These steps should guide you through! Now, you should be good to go!
Hey @CodingExpert, it looks like I have a solution for your issue. However, could you please provide more code examples to demonstrate how you intend to apply it?
Keep in mind that since jstree relies on jQuery, you'll need to import it as well.
You might also need to utilize the scripts configuration.
