I am working on angualar 5 app where I have to include dmn-js library which doesn't have typings available. I followed the steps outlined in angular-cli wiki on how to go about including 3rd party libraries, specifically one outlined under heading - "If the library doesn't have typings available at @types/, you can still use it by manually adding typings for it:"
This is how my code now looks like after -
src/typings.d.ts
/* SystemJS module definition */
declare var module: NodeModule;
declare module 'dmn-js';
interface NodeModule {
id: string;
}
src/app/app.component.ts
import { Component, OnInit } from '@angular/core';
import {HttpClient} from '@angular/common/http';
import * as DmnJS from 'dmn-js';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
title = 'DMN';
constructor(private http: HttpClient){
}
ngOnInit(): void {
var viewer = new DmnJS ({ container: 'body' });
var dmnXML; //DMN 1.1 xml
viewer.importXML(dmnXML, this.handleError);
}
handleError(err: any) {
if (err) {
console.warn('Ups, error: ', err);
}else {
console.log('rendered');
}
}
load(): void {
const url = '/assets/dish-decision.dmn';
this.http.get(url, {
headers: {observe: 'response'}, responseType: 'text'
}).subscribe(
(x: any) => {
console.log('Fetched XML, now importing: ', x);
//this.modeler.importXML(x, this.handleError);
},
this.handleError
);
}
save(): void {
//this.modeler.saveXML((err: any, xml: any) => console.log('Result of saving XML: ', err, xml));
}
}
Now when I compile the code, I get below error. I am not sure what needs to be done to resolve the issue since I followed all steps.
