NoResultsRecommendation

The NoResultsRecommendation is a wrapper for Recommendation component to display recommendations on a Coveo no results page. The component listens to the main search interface and wait for the no results page to be displayed before initializing the child Recommendation component.

The component also takes care of showing/hiding the Recommendation component based on the "no results" state of the main search interface without triggering additional queries.

Disclaimer: This component was built by the community at large and is not an official Coveo JSUI Component. Use this component at your own risk.

Getting Started

1. Install the component into your project.

npm i @coveops/no-results-recommendations

2. Use the Component or extend it

Typescript:

import { NoResultsRecommendation, INoResultsRecommendationOptions } from '@coveops/no-results-recommendations';

Javascript

const NoResultsRecommendation = require('@coveops/no-results-recommendations').NoResultsRecommendation;

3. You can also expose the component alongside other components being built in your project.

export * from '@coveops/no-results-recommendations'

4. Or for quick testing, you can add the script from unpkg

<script src="https://unpkg.com/@coveops/no-results-recommendations@latest/dist/index.min.js"></script>

Disclaimer: Unpkg should be used for testing but not for production.

5. Include the component in your template as follows:

Place the component in your markup:

<div class="CoveoNoResultsRecommendation">
    <div class="CoveoRecommendation">
    <div class="coveo-recommendation-header">
        <div class="coveo-recommendation-title" style="padding-left: 15px;">Recommendations</div>
    </div>
    <div class="coveo-recommendation-body">
        <div class="CoveoResultList" data-layout="list">
        <script id="Default" class="result-template" type="text/html" data-layout="list">
            <div class="coveo-result-row" style="display: flex; align-items: center;">
                <div class="coveo-result-cell" style="margin-left: 10px;margin-right: 10px;height: 30px;">
                    <div class="CoveoIcon" data-small="true" data-with-label="false"></div>
                </div>
                <div class="coveo-result-cell">
                    <a class="CoveoResultLink" data-open-in-sub-tab="true" data-always-open-in-new-window="true"></a>
                </div>
            </div>
            </div>
            </script>
        </div>
    </div>
    </div>
</div>

Options

NoResultsRecommendation is responsible of the initilization of his child Recommendation component. It means all options you want to pass to your Recommendation component need to be passed to your NoResultsRecommendation component.

<script>
    document.addEventListener('DOMContentLoaded', function () {
      // Coveo.SearchEndpoint.endpoints['default'].options.queryStringArguments.viewAllContent = 'true';
      Coveo.init(document.getElementById('search'), {
        Analytics: {
          searchHub: demoConfig.searchHub,
        },
        SearchInterface: {
          pipeline: 'default'
        },
        NoResultsRecommendation: {
          SearchInterface: {
            pipeline: 'default',
            resultsPerPage: 3
          } 
        }
      });
    })
  </script>

Note: You need to use SearchInterface for the options instead of Recommendation because for some reasons Coveo framework will override Recommendation options by default settings.

Extending

Extending the component can be done as follows:

import { NoResultsRecommendation, INoResultsRecommendationOptions } from "@coveops/no-results-recommendations";

export interface IExtendedNoResultsRecommendationOptions extends INoResultsRecommendationOptions {}

export class ExtendedNoResultsRecommendation extends NoResultsRecommendation {}

Contribute

1. Clone the project
2. Copy .env.dist to .env and update the COVEO_ORG_ID and COVEO_TOKEN fields in the .env file to use your Coveo credentials and SERVER_PORT to configure the port of the sandbox - it will use 8080 by default.
3. Build the code base: npm run build
4. Serve the sandbox for live development npm run serve
