Transportedit

This class is responsible to perform the request to Elasticsearch and handling errors, it also handle the 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 just need to inject a little snippet of your code and then continue to use the usual client code, in such case, you should call super.method.

class MyTransport extends Transport {
  request (params, options, callback) {
    // your code
    return super.request(params, options, callback)
  }
}
