jsDoofinder (In progress)

This library allows you to make requests to Doofinder Search Engines and show the results in your website. You'll be able to retrieve and shape your data easily with it.

Summary

Installation

npm

npm install doofinder

bower

bower install doofinder

Downloadable minified javascript file

https://raw.githubusercontent.com/doofinder/js-doofinder/master/dist/doofinder.min.js

CSS

We offer some simple CSS. You can download it in the link https://raw.githubusercontent.com/doofinder/js-doofinder/master/dist/doofinder.css

Quick Start

In this example we'll write a view that will just show results.

Let's begin by showing a simple HTML template (myview.html):

<html lang="en">
<head>
<script type="application/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<script type="application/javascript" src="path/to/your/js/doofinder.min.js"></script>
<script>
(function(doofinder, document){
  $(document).ready(function(){
    // Use here your Search Engine hashid and doofinder zone
    var client = new doofinder.Client('97be6c1016163d7e9bceedb5d9bbc032', 'eu1');
    // #query is the DOM selector that points to the search box
    var queryInputWidget = new doofinder.widgets.QueryInput('#query');
    // #scroll is where we'll display the results
    var resultsWidget = new doofinder.widgets.ScrollResults('#scroll');
    // The controller to rule them all
    var controller = new doofinder.Controller(
        client,
        [queryInputWidget, resultsWidget]
    );
  });
})(doofinder, document);
</script>
<style>
#scroll{
    position: relative;
    height: 800px;
    overflow: auto;
}
</style>
</head>
<body>
  <input type="text" id="query"/>
  <div id="scroll">
  </div>
</body>

Note that we are importing two javascript files:

jquery.min.js: we use it to make sure that everything is being done when the document is ready.
doofinder.min.js: contains doofinder namespace with its classes.

We need to create the inner scroll via css. We get it setting the sroll wrapper's height and overflow as you can see above. It is also necessary set the position to "relative" in order to calculate the scroll position to ask for the next page.

The options we have filled in for the Client:

hashid: the unique hashid of your search engine.
zone: the zone where your search engine is located (eu1, us1, ...).

For the QueryInput widget:

queryInput selector: the CSS selector of our query input.

For the ScrollResults widget:

scroll selector: the CSS selector for the scroll wrapper.

WARNING: Note that Doofinder Search API is protected with CORS, so you must enable the host you are requesting from. You can do this from your Doofinder Administration Panel > Configuration > TODO(@ecoslado) This feature in Admin Panel.

With all this in place you'll have a search box where you can write a query and the results will be shown. Scrolling into the layer you'll see more results.

Classes

Controller

Controller is the class that manages client and widgets. Allows you to make different queries to your index and interact with the different widgets you will instantiate.

constructor

Examples

Example 1: Create a simple template to show results.

In the Quick Start example we composed a simple view using the Doofinder Library. Let's see how to shape the results by a Handlebars template.

 
var resultsTemplate = '{{#each results}}' +
  ' <div>'+
  '   <div>' +
  '     <a href="{{href}}">'+
  '       <img src="{{image}}" alt="{{header}}">'+
  '     </a>'+
  '     <div>'+
  '       <a target="_blank" data-df-hitcounter="{{dfid}}" href="{{href}}">'+
  '         <div>{{header}}</div>' +
  '         <div>{{body}}</div>' +
  '         <div>' +
  '          <span>{{#format-currency}}{{price}}{{/format-currency}}</span>' +
  '         </div>'+
  '       </a>' +
  '    </div>' +
  '  </div>' +
  '</div>' +
  '{{/each}}';

var resultsWidget = new doofinder.widgets.ScrollResults('#scroll', {template: resultsTemplate});

Let's have a look to the template:

We used {{#each results}} to iterate through the items.
We used {{field_name}} tags to print the content of a field.
We used {{#if filed_name}} to check the presence of a field.
We used {{#format-currency}} helper to print the price with the coin symbol and formatted.
Note that we use a data attribute (data-df-hitcounter) to show the dfid. You can use this to send it with the Controller.hit method.

Example 2: Adding extra info to our template.

Maybe you want to add more information to your template dynamically. Imagine you want to show prices lower that a given number, i.e. 100. You can add this variable to the template scope by the option templateVars.

var resultsWidget = new doofinder.widgets.ScrollResults('#scroll', {
  template: resultsTemplate,
  templateVars: {
    maxPrice: 100
    }
  });

So you can modify your template in order to show just the prices lower than maxPrice.

 
var resultsTemplate = '{{#each results}}' +
  ' <div>'+
  '   <div>' +
  '     <a href="{{href}}">'+
  '       <img src="{{image}}" alt="{{header}}">'+
  '     </a>'+
  '     <div>'+
  '       <a target="_blank" data-df-hitcounter="{{dfid}}" href="{{href}}">'+
  '         <div>{{header}}</div>' +
  '         <div>{{body}}</div>' +
  '         {{#lt price ../maxPrice}}'
  '         <div>' +
  '          <span>{{#format-currency}}{{price}}{{/format-currency}}</span>' +
  '         </div>' +
  '         {{/lt}}' +
  '       </a>' +
  '    </div>' +
  '  </div>' +
  '</div>' +
  '{{/each}}';

var resultsWidget = new doofinder.widgets.ScrollResults('#scroll', {
  template: resultsTemplate,
  templateVars: {
    maxPrice: 100
    }
  });

And we have used the {{#lt}} helper to compare the price with the maxPrice. Note that we have written ../maxPrice instead of maxPrice. This is because we are in the loop and we must access to a variable out of results array. For more information about Handlebars templates, click here.

Example 3: Create a custom template function.

Template functions are called helpers in Handlebars. You can create and add custom helpers to your template by using the templateFunctions option. We'll create a helper that convert a text in bold.


{
  templateFunctions: {
    bold: function(options){
      return "<b>" + options.fn(this) + "</b>"
    }
}

This helper will take the text in the tag and will wrapper it with the <b> tag. Note that options.fn(this) returns the text wrapped by the helper.

We'll use the helper to show the header and instantiate the widget.

var resultsTemplate = '{{#each results}}' +
  ' <div>'+
  '   <div>' +
  '     <a href="{{href}}">'+
  '       <img src="{{image}}" alt="{{header}}">'+
  '     </a>'+
  '     <div>'+
  '       <a target="_blank" data-df-hitcounter="{{dfid}}" href="{{href}}">'+
  '         <div>{{#bold}}{{header}}{{/bold}}</div>' +
  '         <div>{{body}}</div>' +
  '         <div>' +
  '          <span>{{#format-currency}}{{price}}{{/format-currency}}</span>' +
  '         </div>'+
  '       </a>' +
  '    </div>' +
  '  </div>' +
  '</div>' +
  '{{/each}}';

var resultsWidget = new doofinder.widgets.ScrollResults('#scroll', {
  template: resultsTemplate,
  templateFunctions: {
    bold: function(options){
        return "<b>" + options.fn(this) + "</b>"
      }
    }
  });
