Elasticsearch javascript connection handler for Superagent
Superagent is widely used and it can easily be made to understand kerberos, in-house CAs and more. This is designed to allow you to pass in any superagent like-object as well as get a callback before the request is sent so you can take an action per request (e.g. set a Authenticate token).
const elasticsearch = require('elasticsearch');
const SuperagentConnector = require('superagent-elasticsearch');
client = new elasticsearch.Client({
host,
log: 'debug',
connectionClass: SuperagentConnector,
});const elasticsearch = require('elasticsearch');
const SuperagentConnector = require('superagent-elasticsearch');
const beforeEachRequest = (r) => async {
const token = await getToken(r.url);
r.set('Authorization', `Negotiate ${token}`);
return;
};
client = new elasticsearch.Client({
host,
log: 'debug',
connectionClass: SuperagentConnector,
superagentConfig: {beforeEachRequest}
});Recommended reading: https://www.npmjs.com/package/kerberos https://gist.github.com/dmansfield/c75817dcacc2393da0a7#file-http_client_spnego-js-L20
