Transportedit
This class is responsible for performing the request to Elasticsearch and handling errors, it also handles sniffing.
const { Client, Transport } = require('@elastic/elasticsearch') class MyTransport extends Transport { request (params, options, callback) { // your code } } const client = new Client({ Transport: MyTransport })
Sometimes you need to inject a small snippet of your code and then continue to
use the usual client code. In such cases, call super.method
:
class MyTransport extends Transport { request (params, options, callback) { // your code return super.request(params, options, callback) } }
