Integrating CanvasJS with Ember.js: A Step-by-Step Guide

*CanvasJS is a JavaScript charting library that allows developers to create interactive and visually appealing charts. While it is commonly integrated with popular frameworks like Angular, Vue, React, etc., it can also be seamlessly integrated with other JavaScript frameworks. In this article, let us explore how to integrate CanvasJS with [Ember.js](https://emberjs.com/)*.

Why Ember.js?

Ember.js is a popular JavaScript framework known for its strong conventions and productivity features, and provides a comprehensive solution for building modern web applications with a focus on developer experience and performance. Integrating CanvasJS with Ember.js can enhance your application’s data visualization capabilities, making it easier to present complex data in an understandable and interactive manner.

Prerequisites

Before we begin, ensure you have the following:

• Node.js and npm installed
• Ember CLI installed (npm install -g ember-cli)
• A basic understanding of Ember.js and CanvasJS

Step-by-Step Integration

1. Create a new Ember.js application.

ember new canvasjs-app
cd canvasjs-app

2. Install CanvasJS in the project

npm install @canvasjs/charts

3. Generate a component called canvasjs-chart.

ember generate component canvasjs-chart

4. Open the generated component files, and import the necessary libraries. Here, we have created a basic column chart using CanvasJS and rendered it.

// app/components/canvasjs-chart.js

import Component from "@glimmer/component";
import { action } from "@ember/object";
import CanvasJS from "@canvasjs/charts";

export default class CanvasjsChartComponent extends Component {
  @action
  renderChart() {
    const chart = new CanvasJS.Chart(this.element, {
      title: {
        text: "Sample Chart"
      },
      theme: "dark2",
      data: [{
        type: "column",
        dataPoints: [
          { label: "Apple", y: 10 },
          { label: "Orange", y: 15 },
          { label: "Banana", y: 25 },
          { label: "Mango", y: 30 },
          { label: "Grape", y: 28 }
        ]
      }]
    });

    chart.render();
  }

  didInsertElement() {
    this.renderChart();
  }
}

// app/templates/components/canvasjs-chart.hbs

<div style="height: 300px; width: 100%;"></div>

5. Now, you can use the canvasjs-chart component in any template within your Ember.js application. For example, we have updated the app/templates/application.hbs file to include the component:

// app/templates/application.hbs

<CanvasjsChart />

6. Finally, run your Ember.js application to see the CanvasJS chart in action:

ember serve

Open your browser and navigate to http://localhost:4200 to view the chart.

By following these steps, you have successfully integrated CanvasJS into your Ember.js application using a custom component named canvasjs-chart. This setup allows you to create dynamic and interactive charts, enhancing the data visualization capabilities of your Ember.js projects. Feel free to play around with the different chart types, and customization options provided by CanvasJS that align with your requirements.
