I tried the sample given in official website of Canvas JS with Angular5. Tried with npm install. But on build of angular application, giving build error as: | export ColumnChart from '../charts/column'; | export StackedColumnChart from '../charts/stacked_column';

Not getting how to solve this issue. Using v1.8.0 of Canvas JS.

• javascript
• charts
• angular5
• canvasjs

CanvasJS doesn’t have official npm package published yet. The package that you are using through npm is not an official one but from a third party.

You can save CanvasJS library (canvasjs.min.js) in source folder of your project (‘src/app’ or ‘src/app/assets/js’ or ‘src/app/lib’) and import it to your app using import * as CanvasJS from './canvasjs.min' (path may vary based on file location like ‘./assets/js/canvasjs.min’ or ‘./lib/canvasjs.min’).

Here is a sample project showing how to import CanvasJS Charts in your Angular 5 App.
