SolrCloud client

Connect to a SolrCloud in node.js.

This library uses Zookeeper to determine the connection to the SolrCloud and returns an instance of Axios that can be used to send requests to the Solr node.

A list of Solr nodes is being retrieved from Zookeeper. The Solr node is being selected randomly.

A basic failover implementation is done by selecting a new node if a request fails.

Installation

npm install --save @pimred/solr-cloud

Usage

const solrCloud = require('@pimred/solr-cloud')

const options = {
  zkConnectionString: 'Connection to Zookeeper',
  collection: 'Name of the Solr collection'
}

solrCloud.createClient(options).then(client => {
  client.get('select', {
    params: {
      q: '*:*'
    }
  }).then(response => console.log(response.data))
})
