Compatible with node>=4.0.0.

Public Facing Search Options

You can configure Algolia integration to your hexo website with the _config.yml file:

algolia:
  applicationID: 'applicationID'
  apiKey: 'apiKey'
  indexName: '...'
Config Key
applicationID Your Algolia Application ID
apiKey A Search-Only API key
indexName The name of the Algolia index to use

These configuration values are accessible from your hexo theme, to be used with Algolia JavaScript client.

Hexo Helpers

Helpers are provided to make your life easier.

Algolia JavaScript Client Tags

The plugin provides an easy way to add Algolia JavaScript API Client either locally (served by hexo) or remotely (via Algolia CDN).

<%- algolia_search() %>

Renders as:

<script src="/assets/algolia/algoliasearchLite.min.js" async></script>
<%- algolia_search_cdn() %>

Renders as:

<script src="https://cdn.jsdelivr.net/algoliasearch/3/algoliasearchLite.min.js" async></script>

Configuration <meta> Tag

You can make your index configuration available to your page and client-side scripts by adding the algolia_config() hexo helper in the <head> of your document.

<%- algolia_search_config() %>

Renders as:

<meta property="algolia:search" data-application-id="..." data-api-key="..." data-index-name="...">

You can access the exposed configuration by querying the data attribute of the algolia:search meta tag:

<script>
const algoliaConfig = document.querySelector('meta[property="algolia:search"]').dataset;
 
const client = algoliasearch(algoliaConfig.applicationID, algoliaConfig.apiKey);
const index = client.initIndex(algoliaConfig.indexName);
</script> 

Indexing Content

Content can be indexed from the command line with the help of the hexo algolia command.

$ ./node_modules/.bin/hexo algolia

API Key

A separate API Key must be provided as an environment variable named HEXO_ALGOLIA_INDEXING_KEY. Create it with these limited write access permissions: Add records, Delete records, List indices, Delete index.

export HEXO_ALGOLIA_INDEXING_KEY=…
$ ./node_modules/.bin/hexo algolia

Usage

$ ./node_modules/.bin/hexo help algolia
Usage: ./node_modules/.bin/hexo algolia

Description:
Index your content in Algolia Search API

Options:
  --dry-run          Does not push content to Algolia
  --flush            Does not reset the Algolia index before starting the indexation

Security Concerns

Never store your Admin API Key as apiKey in the _config.yml file: it would give full control of your Algolia index to others and you don't want to face the consequences.

Please read Algolia Security guide thoroughly if you need some more informations about this.
