elasticsearch: create index with mappings using javascript

Question

I\'m trying to create an elasticsearch index with mappings using the official javascript client.

My code is as follows:

Answer 1

Note: this uses client.indices.create() and not client.indices.putMapping()

I recently succeeded in creating an index with a custom mapping like this:

client.indices.create({
  index: 'yourIndex',
  body: {
    yourIndex: {
      mappings: {
        yourType: {
          properties: {
            yourText: {
              type: 'string',
            }
          }
        }
      }
    }
  }
});

It seems you have to start defining the body with your index, followed by the mappings keyword, followed by your type and so forth. I used the elasticsearch package version 15.4.1 with elastic version 6.5.4
