hexo theme

Install

$ npm install --save hexo-algolia

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 Theme Setup

Helpers are provided to make your life easier.

Include Algolia JavaScript Client

The algolia_search theme helper adds the Algolia search client to your pages.

<%- algolia_search() %>

Renders as:

<script src="/assets/algolia/algoliasearchLite.min.js" async></script>

Configure Algolia JavaScript Client

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() %>

Once done, you can retrieve Algolia configuration by querying the data attribute of the algolia:search meta tag.

const algoliaConfig = document.querySelector('meta[property="algolia:search"]').dataset;

const client = algoliasearch(algoliaConfig.applicationId, algoliaConfig.apiKey);
const index = client.initIndex(algoliaConfig.indexName);

Display Search Results

It is now up to you to use the aforementioned example to trigger a search and display the results in your page.

If you need some help, have a look at the search client doc and the tutorials.

Indexing Content

Content is indexed 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 (default: false).
  --flush         Resets the Algolia index before starting the indexation (default: false).
  --indexing-key  An algolia API key with add/delete records permissions.
		  It should be different than the search-only API key configured in _config.yml.
  --layouts       A comma-separated list of page layouts to index (default: "page").

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.
