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.
