Findify Merchant JS npm (scoped)

Getting started

Accessing API:

After MJS loads it start listening to objects in window.findifyApiRegistry and processing them immediately. By using this functionality you can modify response, change styles and inject your code to every part of MJS lifecycle.

Customize styles in iFrame:

You can modify CSS styles of components by simply adding object with single key style and styles or link to CSS file in thats value. e.q:

  style: 'body{ background: black; }'

Include JavaScript files in iFrame:

Same as with adding styles, you can add to registry object with key script and value with link to script you would like to include. e.q:

  script: 'http://path_to_your_javascript_file'

Modify data and view on fly with Hooks.

MJS uses powerful hook system, which allow you to modify data views inside components lifecycle. Hook object contains three fields:

  1. hook - name of hook, is [context].[component] composition, which specifies component where hook will be injected.
  2. mapProps - function which allow you to change data which will be passed to component.
  3. didMount - function triggers on component view was rendered in window.
  4. didUpdate - similar to previews one, but triggers every time when view was changed.


  hook: 'search.products',

  didMount: function(data) {
    $(data.node).appendChild('<div>CUSTOM HTML</div>');

  mapProps: function(props) {
    var width = props.size.width;
    if (width > 1000) {
      return { columns: 4 };
    } else {
      return { columns: 3 };

Available hooks:


  • search.results - Search results container
  • search.facets - Desktop facets list
  • search.facet - Single desktop facet
  • search.products - Products grid
  • search.product - Single product item
  • search.noResults - Products list, which renders when no matching products found


  • autocomplete.suggestions - Suggestions list
  • autocomplete.products - Products matches grid
  • autocomplete.product - Single product item


  • recommendations.slider - Recommendations list with type "Carousel"
  • recommendations.products - Recommendations list with type "Grid"
  • recommendations.product - Single recommendation


  • mobile.facets - Facets list in mobile view
  • mobile.facet - Single facet in mobile view

Lifecycle functions:

mapProps, ({ config, ...rest }) - Allow you to change props which will be passed to component, it contains config and other component specific props. Important - don't execute slow code here, it will affect component rendering speed

didMount, ({ node: DOMNode, data: componentProps }) - Function which will be executed on component did mount, it will pass node and component props to callback. We recommend to do all DOM manipulations here.

didUpdate, ({ node: DOMNode, data: componentProps }) - same as didMount, but will fire every time when props was updated


We will try to follow semver as close as possible. That means bug fixes will be patch releases (1.0.1 -> 1.0.2), additional functionality like new endpoints will be minor releases (1.0.1 -> 1.1.0) and breaking changes to both the library and the API endpoints it hits, will be major releases (1.0.1 -> 2.0.0).
