# Gatsby plugin Algolia
> This plugin is in _beta_ and not officially supported yet
>
> Feel free to open issues for any questions or ideasYou can specify a list of queries to run and how to transform them into an array of objects to index. When you run `gatsby build`, it will publish those to Algolia.
```mermaid
graph LR
A[Source 1] --> |query| Gatsby
B[Source 2] --> |query| Gatsby
C[Source 3] --> |query| GatsbyGatsby --> |gatsby build| Algolia
```Here we have an example with some data that might not be very relevant, but will work with the default configuration of `gatsby new`
```shell
yarn add gatsby-plugin-algolia
```First add credentials to a .env file, which you won't commit. If you track this in your file, and especially if the site is open source, you will leak your admin API key. This would mean anyone is able to change anything on your Algolia index.
```shell
// .env.production
ALGOLIA_APP_ID=XXX
ALGOLIA_API_KEY=XXX
ALGOLIA_INDEX_NAME=XXX
``````js
require('dotenv').config({
path: `.env.${process.env.NODE_ENV}`,
});// gatsby-config.js
const myQuery = `
query {
pages: allSitePage {
nodes {
# querying id is required
id
component
path
componentChunkName
jsonName
internal {
# querying internal.contentDigest is required
contentDigest
type
owner
}
}
}
}
`;const queries = [
{
query: myQuery,
queryVariables: {}, // optional. Allows you to use graphql query variables in the query
transformer: ({ data }) => data.pages.nodes, // optional
indexName: 'index name to target', // overrides main index name, optional
settings: {

},

},
mergeSettings: false, // optional, defaults to false. See notes on mergeSettings below
concurrentQueries: false, // default: true

continueOnFailure: false, // default: false, don't fail the build if Algolia indexing fails
algoliasearchOptions: undefined, // default: { timeouts: { connect: 1, read: 30, write: 30 } }, pass any different options to the algoliasearch constructor
},
},
],
};
```The index will be synchronised with the provided index name on Algolia on the `build` step in Gatsby. This is not done earlier to prevent you going over quota while developing.
## Partial Updates
This plugin will update only the changed or deleted nodes on your Gatsby site.
**We rely on Gatsby's default `contentDigest` field, so make sure it is queried.**
## Settings
You can set settings for each index individually (per query), or otherwise it will keep your existing settings.
### Merge Settings
`mergeSettings` allows you to preserve settings changes made on the Algolia website. The default behavior (`mergeSettings: false`) will wipe out your index settings and replace them with settings from the config on each build.
When set to true, the config index settings will be merged with the existing index settings in Algolia (with the config index settings taking precendence).
NOTE: When using `mergeSettings`, any **deleted** settings from the config settings will continue to be persisted since they will still exist in Algolia. If you want to remove a setting, be sure to remove it from both the config and on Algolia's website.
## Concurrent Queries
Sometimes, on limited platforms like Netlify, concurrent queries to the same index can lead to unexpected results or hanging builds. Setting `concurrentQueries` to `false` makes it such that queries are run sequentially rather than concurrently, which may solve some concurrent access issues. Be aware that this option may make indexing take longer than it would otherwise.
## Transformer
The `transformer` field accepts a function and optionally you may provide an `async` function.
Adding a transformer parameter can be useful if the `internal.contentDigest` is more stable than your object. You can for example replace the Gatsby-provided `internal.contentDigest` with a hash of the object.
```js
const crypto = require('crypto');function transformer(data) {
return data.map(item => {
const hash = crypto
.createHash('md5')
.update(JSON.stringify(item))
.digest('hex');return {
...item,
internal: {
...item.internal,
contentDigest: hash,
},
};
});
}
```## Feedback
This is the very first version of our plugin and isn't yet officially supported. Please leave all your feedback in GitHub issues 😊
## FAQ
### Why do my updates not show up?
This could be happening for a few reasons:
#### Development mode
You are using the `gatsby-plugin-algolia` plugin in development mode. The plugin will only push to Algolia when you run `gatsby build`. This is to prevent you from going over your quota while developing.
#### Static `internal.contentDigest`
Some Gatsby plugins don't create a new `internal.contentDigest`, even if the content has changed. To fix this, use a [`transformer`](#transformer) to create a new `internal.contentDigest` based on the content of the node.
