Coveo JavaScript Search UI Framework

Installation

You should install the Coveo JavaScript Search UI Framework as an npm package:

npm install --save coveo-search-ui

All resources will be available under node_modules/coveo-search-ui/bin. You can include those in your pages with <script> tags. This will make the variable Coveo globally available in your page.

If you are using a module bundler (Browserify, Webpack, rollup, etc.), you can use require('coveo-search-ui') or import * as Coveo from 'coveo-search-ui'.

Alternatively, you can download the latest version of the Coveo JavaScript Search UI Framework here.

Including the Resources from a CDN

Since the April 2017 release, it is possible to access the resources of any specific Coveo JavaScript Search Framework official release (from version 1.2537 on) through a content delivery network (CDN).

You can simply use a URL such as https://static.cloud.coveo.com/searchui/v[VERSION]/[PATH_TO_FILE], where you replace [VERSION] by the actual release version number you wish to use and [PATH_TO_FILE] by the path of the file you require.

Example:

The following tags include the 1.2537 version (April 2017 release) of the CoveoJsSearch.min.js, templateNew.js and CoveoFullSearchNewDesign.css files.

<head>

  [ ... ]

  <script src="https://static.cloud.coveo.com/searchui/v1.2537/js/CoveoJsSearch.min.js"></script>
  <script src="https://static.cloud.coveo.com/searchui/v1.2537/js/templates/templatesNew.js"></script>
  <link rel="stylesheet" href="https://static.cloud.coveo.com/searchui/v1.2537/css/CoveoFullSearchNewDesign.css" />

  [ ... ]

 </head>

Basic Usage

<!-- Include the library scripts. -->
<script src="js/CoveoJsSearch.js"></script>
<script src="js/templates/templates.js"></script>

<!-- Each DOM element with a class starting with "Coveo" (uppercase) will instantiate a component. -->
<body id="search" class='CoveoSearchInterface'>

    <!-- Each DOM element with a class starting with "coveo-" (lowercase) is strictly for CSS/alignment purpose. -->
    <div class='coveo-search-section'>

        <!-- Any Coveo component can be removed (or added); none is actually required for the page to "load". -->
        <div class="CoveoSearchbox"></div>
    </div>

    <!-- The "data-" attributes of each component allow you to pass options to this specific component instance. -->
    <div class="CoveoFacet" data-title="Author" data-field="@author" data-tab="All"></div>
    <div class="CoveoFacet" data-title="Year" data-field="@year" data-tab="All"></div>
    <script>
        // The following line shows you how you could configure an endpoint against which to perform your search.
        // Coveo.SearchEndpoint.configureCloudEndpoint('MyCoveoCloudEnpointName', 'my-authentification-token');

        // We provide a sample endpoint with public sources for demo purposes.
        Coveo.SearchEndpoint.configureSampleEndpoint();

        // Initialize the framework by targeting the root in the interface.
        // It does not have to be the document body.
        Coveo.init(document.body);
    </script>
</body>

You can find more examples of fully configured pages in the ./pages folder.

A tutorial is available to help you get started (see Coveo JavaScript Search UI Framework Getting Started Tutorial).

Build

You should have node 9.5.0 (or later) installed to build this project.

npm install -g yarn
yarn global add gulp
yarn install
gulp

Important Gulp Tasks

  • gulp default: Builds the entire project (CSS, templates, TypeScript, etc.)
  • gulp compile: Builds only the TypeScript code and generates its output in the ./bin folder.
  • gulp css: Builds only the Sass code and generates its output in the ./bin folder.
  • gulp sprites: Regenerates the sprites image as well as the generated Sass/CSS code.
  • gulp test: Builds and runs the unit tests.
  • gulp doc: Generates the documentation website for the project.
  • gulp dev: Starts a webpack dev server for the project.
  • gulp devTest: Starts a webpack dev server for the unit tests.

Dev Server

Make sure you were able to run gulp entirely without any errors first. Then you can start the dev-server:

gulp dev

This will start a webpack-dev-server instance (see Webpack Dev Server).

You can now load http://localhost:8080/index.html in a web browser.

Any time you hit Save in a source file, the bundle will be recompiled and the dev page will reload.

If you need to modify the content of the search page (i.e., the markup itself, not the TypeScript code), modify the index.html page under ./bin. This page is not committed to the repository, so you do not have to worry about breaking anything. However, if you feel like you have a good reason to modify the original index.html, feel free to do so.

You might need to assign more memory to Webpack if you see errors about heap out of memory. To do so, use this command :

node --max_old_space_size=8192 ./node_modules/gulp/bin/gulp.js dev;

Tests

Tests are written using Jasmine. You can use npm run test to run the tests in Chrome Headless.

If you wish to write new unit tests, you can do so by starting a new webpack-dev-server instance.

To start the server, run gulp devTest.

Load http://localhost:8081/tests/SpecRunner.html.

Every time you hit Save in a source file, the dev server will reload and re-run your tests.

Code coverage will be reported in ./bin/coverage

Documentation

General reference documentation is generated using TypeDoc (see Coveo JavaScript Search UI Framework - Reference Documentation). The generated reference documentation lists and describes all available options and public methods for each component.

Handwritten documentation with more examples is also available (see JavaScript Search Framework Home).

A tutorial is available (see JavaScript Search Framework Getting Started Tutorial). If you are new to the Coveo JavaScript Search UI Framework, you should definitely consult this tutorial, as it contains valuable information.

You can also use Coveo Search to find answers to any specific issues/questions (see search.coveo.com).
