docs-searchbar.js is a front-end SDK for Meilisearch providing a search bar for your documentation.

docs-searchbar.js comes with a css template. The default styling of this library fits a documentation search bar, but you can customize it.

To make it work, You need to have your documentation's content in a Meilisearch instance. If not already the case, you can achieve this using docs-scraper.

Meilisearch is an open-source search engine. Discover what Meilisearch is!

Index your data

The goal of this library is to provide a front-end search bar into your own documentation. To make that possible, you need to gather your website content in advance, and index it in a Meilisearch instance.

Luckily, we provide all the tools that you need, and can help you through the whole process, if you follow this guide 🚀

Note: If you want to try out docs-searchbar.js as a first introduction, try out our playground.

Use your own scraper

We recommend using the docs-scraper tool to scrape your website, but this is not mandatory.

If you already have your own scraper but you still want to use Meilisearch and docs-searchbar.js, check out this discussion.

🎬 Getting Started

ES module

Add an input tag with the attribute id="search-bar-input in one of your HTML file.

<input type="search" id="search-bar-input" />

Then, import docs-searchbar.js and run the docsSearchBar function. For more explaination of the required parameters, see next section.

import docsSearchBar from 'docs-searchbar.js'

docsSearchBar({
  hostUrl: 'https://mymeilisearch.com',
  apiKey: 'XXX',
  indexUid: 'docs',
  inputSelector: '#search-bar-input',
})

HTML

Add the following code to one of your HTML files.

<!DOCTYPE html>
<html>
  <head>
    <link
      rel="stylesheet"
      href="https://cdn.jsdelivr.net/npm/docs-searchbar.js@{version}/dist/cdn/docs-searchbar.min.css"
    />
  </head>

  <body>
    <input type="search" id="search-bar-input" />
    <script src="https://cdn.jsdelivr.net/npm/docs-searchbar.js@{version}/dist/cdn/docs-searchbar.min.js"></script>
    <script>
      docsSearchBar({
        hostUrl: 'https://mymeilisearch.com',
        apiKey: 'XXX',
        indexUid: 'docs',
        inputSelector: '#search-bar-input',
        debug: true, // Set debug to true if you want to inspect the dropdown
      })
    </script>
  </body>
</html>

The hostUrl and the apiKey (optional) fields are the credentials of your Meilisearch instance.
indexUid is the index identifier in your Meilisearch instance in which your website content is stored.
inputSelector is the id attribute of the HTML search input tag. As an alternative the dom element can be supplied with inputElement directly.

Your documentation content is not indexed yet? Check out this tutorial.

WARNING: We recommend providing the Meilisearch public key, which is enough to perform search requests.

Styling

docs-searchbar.js comes with a css template. It has to be added in your project in the following way:

In an ES+ environment:

import 'docs-searchbar.js/dist/cdn/docs-searchbar.css'

In a HTML file, the link tag should be added in your header:

<link
  rel="stylesheet"
  href="https://cdn.jsdelivr.net/npm/docs-searchbar.js@latest/dist/cdn/docs-searchbar.min.css"
/>

🎨 Customization

The default behavior of this library fits perfectly for a documentation search bar, but you might need some customizations.

Optional parameters

When calling the docsSearchBar method, you can add optional fields:

queryHook

queryHook takes a callback function as value. This function will be called on every keystroke to transform the typed keywords before querying Meilisearch. By default, it does not do anything, but it is the perfect place for you to add some preprocessing or custom functionality.

transformData

transformData takes a callback function as value. This function will be called on every hit before displaying them. By default, it does not do anything, but it lets you add any post-processing around the data you received from Meilisearch.

handleSelected

handleSelected takes a callback function a value. This function is called when a suggestion is selected (either from a click or a keystroke). By default, it displays anchor links to the results page. Here is an example to override this behavior:

docsSearchBar({
  // ...
  handleSelected: function (input, event, suggestion, datasetNumber, context) {
    // Prevents the default behavior on click and rather opens the suggestion
    // in a new tab.
    if (context.selectionMethod === 'click') {
      input.setVal('')

      const windowReference = window.open(suggestion.url, '_blank')
      windowReference.focus()
    }
  },
})

Note that, by default, you can already open a new tab thanks to the CMD/CTRL + Click action.

The function is called with the following arguments:

  • input: a reference to the search input element. It comes with the .open(), .close(), .getVal() and .setVal() methods.

  • event: the actual event triggering the selection.

  • suggestion: the object representing the current selection. It contains a .url key representing the destination.

  • datasetNumber: this should always be equal to 1 as docs-searchbar.js is searching into one dataset at a time. You can ignore this attribute.

  • context: additional information about the selection. Contains a .selectionMethod key that can be either click, enterKey, tabKey or blur, depending on how the suggestion was selected.

meilisearchOptions

You can forward search parameters to the Meilisearch API by using the meilisearchOptions key. Checkout out the Meilisearch documentation about search parameters.

For example, you might want to increase the number of results displayed in the dropdown:

docsSearchBar({
  meilisearchOptions: {
    limit: 10,
  },
})

enableDarkMode

Allows you to display the searchbar in dark mode. It is useful if your website has dark mode support and you also want the searchbar to appear in a dark version. You can always edit the style of the searchbar to match the style of your website. When the option enableDarkMode is set to auto, the searchbar automatically sets the mode to the system mode.

enableDarkMode has three possible states:

  • false: enforce light mode.
  • true: enforce dark mode.
  • auto: system mode (light or dark).

Example:

docsSearchBar({
  ...
  enableDarkMode: 'auto'
})

Dark mode with enableDarkMode set to auto and system mode set to dark:

docs-searchbar with dark mode

enhancedSearchInput

When set to true, a theme is applied to the search box to improve its appearance. It adds the .searchbox class which can be used to further customise the search box.

Example:

docsSearchBar({
  ...
  enhancedSearchInput: true
})
More Examples

Here is a basic HTML file used in the playground of this repository.

As a more concrete example, you can check out the configuration applied in the Meilisearch plugin for VuePress.

Styling

/* Main dropdown wrapper */
.meilisearch-autocomplete .dsb-dropdown-menu {
  width: 500px;
}

/* Main category */
.meilisearch-autocomplete .docs-searchbar-suggestion--category-header {
  color: darkgray;
  border: 1px solid gray;
}

/* Category */
.meilisearch-autocomplete .docs-searchbar-suggestion--subcategory-column {
  color: gray;
}

/* Title */
.meilisearch-autocomplete .docs-searchbar-suggestion--title {
  font-weight: bold;
  color: black;
}

/* Description */
.meilisearch-autocomplete .docs-searchbar-suggestion--text {
  font-size: 0.8rem;
  color: gray;
}

/* Highlighted text */
.meilisearch-autocomplete .docs-searchbar-suggestion--highlight {
  color: blue;
}

TIPS: When inspecting the dropdown markup with your browser tools, you should add debug: true to your docsSearchBar call to prevent it from closing on inspection.
