Elasticsearch: Make GET request of index's fields from mapping

Question

I want to autotest some things for elastic. One of them it's to: 1. GET all fields from mapping 2. Check that all fields are present 3. Check that fields with present _id in their names have type integer. But let's get started at least with returning mappings. I do it successfully in kibana console with

GET /persons/_mappings

But did not find any information about how to do it in requests: Currently, I have this request:

let client = await connectElastic();
        const response = await client.search({
            method: 'GET',
            index: 'persons',
            // perheps here must be some parameter?
        });

Using elasticsearch.js library elasticsearch.js:

first create client:

var elasticsearch = require('elasticsearch');
var client = new elasticsearch.Client({
  host: 'localhost:9200',
  log: 'trace'
});

You can use this api:

client.indices.getMapping({ index: 'persons'}, (err, res) => {
     if (!err) {
         console.log(res);
     }
});

Hi Tarek. Thank you. That's exactly what I needed. I see I've read this elastic.co/guide/en/elasticsearch/client/javascript-api/current/… documentation in very "scratch the surface" manner. Need to read it thoroughly. By the way, you just missed a bit from my question. The client is already built, I don't know why you haven't seen it and proposed me to create the client :-)

You are very welcome Alexander. I know you created the client, I just wanted to include the require of the library, link to it, and creation of the client for anyone else who need the same solution :)
