Generate and send indices from Hugo static sites for use with Algolia.
An alternative to the Docsearch plugin, allowing for manual index exports. Supports YAML, JSON, and TOML front matter.
Install hugo-algolia
from npm
npm install hugo-algolia
Or
yarn add hugo-algolia
hugo-algolia
looks into the /content
folder of your site by default and places a JSON file with the export into the /public
folder, but if you'd like to use custom inputs and outputs just pass an -i
or -o
followed by your path via command line.
In your package.json file:
//Default
scripts: {
"index": "hugo-algolia"
}
or
scripts: {
"index": "hugo-algolia -i \"content/subdir/**\" -o public/my-index.json"
}
You can send your index to Algolia by including your API key, app ID, and index name in your config.yaml, which you can find in your Algolia account dashboard. Then, pass an -s
flag to your hugo-algolia
command.
---
baseURL: "/"
languageCode: "en-us"
title: "Your site name"
theme: "your-theme"
description: "A cool site!"
algolia:
index: "index-name"
key: "[your API key]"
appID: "[your app id]"
---
then
scripts: {
"index-and-send": "hugo-algolia -s"
}
If you don't want to set your write key in your config.yaml
, you can also use environment variables. Just set a variable ALGOLIA_WRITE_KEY
to the write key for your account, and the module will use that instead.
That's cool! Just set the index
param in your file's front matter to false
and hugo-algolia
will skip it during the indexing process. Content with draft: true
will also be ignored.
There are a few flags you can use to customize your indices:
-m
- Create multiple indices based on the default index
param in the front matter of each markdown file, or another specified param.
hugo-algolia -m "[optional-custom-param]"
-p
- Partially index files using only specified params.
hugo-algolia -p "[param], [param], [param]"
-all
- By default, hugo-algolia
skips content that doesn't have an index
param, or whichever param you specify in your command. If you'd like to index those files, use this flag.
--config
- Pass in a custom config file.
hugo-algolia --config ./mysweetconfig.yaml
hugo-algolia -m "categories" -p "title, uri, categories" -all
This command would create multiple indices depending on the category of each .md
file, but only inlcude the title
, uri
, and categories
information in the output file.
The gray-matter
package used in this module does not support TOML front matter out of the box. If you're using TOML in your front matter, just use the toml
flag in your command.
hugo-algolia --toml
Algolia assigns each entry in the index an objectID. It uses this attribute as primary key for an entry. If you want to update an entry, you must send the objectID for the entry you want to update. To prevent duplicated content, this package uses the page's URI as objectID. This way, you can generate the index as many times as you want and Algolia will only index content that has changed. If you want to override an objectID for an entry, you can especify it in the frontmatter.
