superagent-elasticserach

Elasticsearch javascript connection handler for Superagent

Why?

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).

Usage

Simple

const elasticsearch = require('elasticsearch');
const SuperagentConnector = require('superagent-elasticsearch');

client = new elasticsearch.Client({
    host,
    log: 'debug',
    connectionClass: SuperagentConnector,
});

Kerberos

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}
});
