Add SurveyJS Dashboard to an Angular Application

This step-by-step tutorial will help you get started with SurveyJS Dashboard in an Angular application. To add SurveyJS Dashboard to your application, follow the steps below:

• Install the survey-analytics npm Package
• Configure Styles
• Load Survey Results
• Configure the Visualization Panel
• Render the Visualization Panel

As a result, you will create the following dashboard:

If you are looking for a quick-start application that includes all SurveyJS components, refer to the following GitHub repository: SurveyJS + Angular CLI Quickstart Template.

SurveyJS Dashboard is distributed as a survey-analytics npm package. Run the following command to install it:

npm install survey-analytics --save

SurveyJS Dashboard depends on the Plotly.js library. Use the following commands to install type definitions for this library:

npm i @types/plotly.js-dist-min --save-dev

Due to the design of Plotly.js exports, you should also open the tsconfig.json file and set the allowSyntheticDefaultImports flag to true:

{
  "compilerOptions": {
    // ...
    "allowSyntheticDefaultImports": true
  }
}

Open the angular.json file and reference the SurveyJS Dashboard style sheet:

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  // ...
  "projects": {
    "project-name": {
      "projectType": "application",
      // ...
      "architect": {
        "build": {
          // ...
          "options": {
            // ...
            "styles": [
              "src/styles.css",
              "node_modules/survey-analytics/survey.analytics.min.css"
            ],
            // ...
          }
        }
      }
    }
  }
}

You can access survey results as a JSON object within the SurveyModel's onComplete event handler. Send the results to your server and store them with a specific survey ID. Refer to the Handle Survey Completion help topic for more information.

To load the survey results, send the survey ID to your server and return an array of JSON objects:

import { AfterViewInit, Component } from '@angular/core';

const SURVEY_ID = 1;

@Component({
  // ...
})
export class AppComponent implements AfterViewInit {
  // ...
  ngAfterViewInit(): void {
    loadSurveyResults("https://your-web-service.com/" + SURVEY_ID)
      .then((surveyResults) => {
        // ...
        // Configure and render the Visualization Panel here
        // Refer to the help topics below
        // ...
      });
  }
}

function loadSurveyResults (url) {
  return new Promise((resolve, reject) => {
    const request = new XMLHttpRequest();
    request.open('GET', url);
    request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
    request.onload = () => {
      const response = request.response ? JSON.parse(request.response) : [];
      resolve(response);
    }
    request.onerror = () => {
      reject(request.statusText);
    }
    request.send();
  });
}

For demonstration purposes, this tutorial uses predefined survey results. The following code shows a survey model and the structure of the survey results array:

const surveyJson = {
  elements: [{
    name: "satisfaction-score",
    title: "How would you describe your experience with our product?",
    type: "radiogroup",
    choices: [
      { value: 5, text: "Fully satisfying" },
      { value: 4, text: "Generally satisfying" },
      { value: 3, text: "Neutral" },
      { value: 2, text: "Rather unsatisfying" },
      { value: 1, text: "Not satisfying at all" }
    ],
    isRequired: true
  }, {
    name: "nps-score",
    title: "On a scale of zero to ten, how likely are you to recommend our product to a friend or colleague?",
    type: "rating",
    rateMin: 0,
    rateMax: 10,
  }],
  showQuestionNumbers: "off",
  completedHtml: "Thank you for your feedback!",
};

const surveyResults = [{
  "satisfaction-score": 5,
  "nps-score": 10
}, {
  "satisfaction-score": 5,
  "nps-score": 9
}, {
  "satisfaction-score": 3,
  "nps-score": 6
}, {
  "satisfaction-score": 3,
  "nps-score": 6
}, {
  "satisfaction-score": 2,
  "nps-score": 3
}];

Analytics charts are displayed in a Visualization Panel. Specify its properties in a configuration object. In this tutorial, the object enables the allowHideQuestions property:

const vizPanelOptions = {
  allowHideQuestions: false
}

Pass the configuration object, survey questions, and results to the VisualizationPanel constructor as shown in the code below to instantiate the Visualization Panel. Assign the produced instance to a constant that will be used later to render the component:

import { AfterViewInit, Component } from '@angular/core';
import { Model } from 'survey-core';
import { VisualizationPanel } from 'survey-analytics';

const surveyJson = { /* ... */ };
const surveyResults = [ /* ... */ ];
const vizPanelOptions = { /* ... */ };

@Component({
  // ...
})
export class AppComponent implements AfterViewInit {
  ngAfterViewInit(): void {
    const survey = new Model(surveyJson);
    const vizPanel = new VisualizationPanel(
      survey.getAllQuestions(),
      surveyResults,
      vizPanelOptions
    );
  }
}

import { AfterViewInit, Component } from '@angular/core';
import { Model } from 'survey-core';
import { VisualizationPanel } from 'survey-analytics';

const surveyJson = {
  elements: [{
    name: "satisfaction-score",
    title: "How would you describe your experience with our product?",
    type: "radiogroup",
    choices: [
      { value: 5, text: "Fully satisfying" },
      { value: 4, text: "Generally satisfying" },
      { value: 3, text: "Neutral" },
      { value: 2, text: "Rather unsatisfying" },
      { value: 1, text: "Not satisfying at all" }
    ],
    isRequired: true
  }, {
    name: "nps-score",
    title: "On a scale of zero to ten, how likely are you to recommend our product to a friend or colleague?",
    type: "rating",
    rateMin: 0,
    rateMax: 10,
  }],
  showQuestionNumbers: "off",
  completedHtml: "Thank you for your feedback!",
};

const surveyResults = [{
  "satisfaction-score": 5,
  "nps-score": 10
}, {
  "satisfaction-score": 5,
  "nps-score": 9
}, {
  "satisfaction-score": 3,
  "nps-score": 6
}, {
  "satisfaction-score": 3,
  "nps-score": 6
}, {
  "satisfaction-score": 2,
  "nps-score": 3
}];

const vizPanelOptions = {
  allowHideQuestions: false
}

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements AfterViewInit {
  title = 'SurveyJS Dashboard for Angular';

  ngAfterViewInit(): void {
    const survey = new Model(surveyJson);
    const vizPanel = new VisualizationPanel(
      survey.getAllQuestions(),
      surveyResults,
      vizPanelOptions
    );
  }
}

Switch to the component template. Add a page element that will serve as the Visualization Panel container:

<!-- app.component.html -->
<div id="surveyVizPanel"></div>

To render the Visualization Panel in the page element, call the render(containerId) method on the Visualization Panel instance you created in the previous step:

// ...
@Component({
  // ...
})
export class AppComponent implements AfterViewInit {
  ngAfterViewInit(): void {
    // ...
    vizPanel.render("surveyVizPanel");
  }
}

To view the application, run ng serve in a command line and open http://localhost:4200/ in your browser.

<div id="surveyVizPanel"></div>

import { AfterViewInit, Component } from '@angular/core';
import { Model } from 'survey-core';
import { VisualizationPanel } from 'survey-analytics';

const surveyJson = {
  elements: [{
    name: "satisfaction-score",
    title: "How would you describe your experience with our product?",
    type: "radiogroup",
    choices: [
      { value: 5, text: "Fully satisfying" },
      { value: 4, text: "Generally satisfying" },
      { value: 3, text: "Neutral" },
      { value: 2, text: "Rather unsatisfying" },
      { value: 1, text: "Not satisfying at all" }
    ],
    isRequired: true
  }, {
    name: "nps-score",
    title: "On a scale of zero to ten, how likely are you to recommend our product to a friend or colleague?",
    type: "rating",
    rateMin: 0,
    rateMax: 10,
  }],
  showQuestionNumbers: "off",
  completedHtml: "Thank you for your feedback!",
};

const surveyResults = [{
  "satisfaction-score": 5,
  "nps-score": 10
}, {
  "satisfaction-score": 5,
  "nps-score": 9
}, {
  "satisfaction-score": 3,
  "nps-score": 6
}, {
  "satisfaction-score": 3,
  "nps-score": 6
}, {
  "satisfaction-score": 2,
  "nps-score": 3
}];

const vizPanelOptions = {
  allowHideQuestions: false
}

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements AfterViewInit {
  title = 'SurveyJS Dashboard for Angular';

  ngAfterViewInit(): void {
    const survey = new Model(surveyJson);
    const vizPanel = new VisualizationPanel(
      survey.getAllQuestions(),
      surveyResults,
      vizPanelOptions
    );
    vizPanel.render("surveyVizPanel");
  }
}
