Did you manage to run it locally and add documents? I am experiencing some issues with docs. not being added on load :)

Additionally, would be great if we could add linting. Run yarn add eslint@latest and format it :)

ElasticSearch Client mutates the config when passed in raw (see here). This means, that ElasticSearch will complain the second time we try to init a client, since its two different objects.

Instead we should add a function:

getConfig() {
    return { ...this.options_.config }
}

And use this when initializing the function: this.client_ = new Client(options.config)

Hope this makes sense :)

ElasticSearch will complain if the index does not exist. Let's add a try / catch and create an index, if we receive an error 404 and a message saying that the index is not present. Something along the lines of:

async updateSettings(indexName, settings) {
    try {
      return await this.client_.indices.putSettings({
        index: indexName,
        body: { settings: settings },
      })
    } catch (error) {
      if (error.status === 404) {
        await this.createIndex(indexName, {})
        return await this.updateSettings(indexName, settings)
      }
    }
  }

Add a couple of build scripts:

"build": "babel src --out-dir dist/ --ignore **/__tests__",
"prepare": "cross-env NODE_ENV=production npm run build",
"watch": "babel -w src --out-dir dist/ --ignore **/__tests__",

Currently, I didn't test them, I will test them on weekend.

Hey, thanks for the PR! Since v2 brought a lot of architectural and API changes on the backend, we will be closing this ticket.
