Transportedit
This class is responsible for performing the request to Elasticsearch and handling errors, it also handles sniffing.
const { Client } = require('@elastic/elasticsearch')
const { Transport } = require('@elastic/transport')
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)
}
}
