Typescript type definitions for elasticsearch-browser

Question

I was attempting to use the JS library for elasticsearch in an Angular application. The library imported with no problem:

npm install elasticsearch
npm install @types/elasticsearch

And then the IDE could recognize the types for the API. However it would not work in the browser. Instead I had to use

npm install elasticsearch-browser

This works and now the API works but there is no @types/elasticsearch to install. I can proceed with development but it really helps to have the IDE check my code. Does anyone know if there is a type-definition out there somewhere?

A possible work-around is to somehow import the @types/elasticsearch definitions and use them for the elasticsearch-browser package. But I don't know how to do that. Any help?

I don't know if it's the right way, but this worked for me:

elasticsearch.d.ts:

declare module "elasticsearch-browser" {
  import elasticsearch from "elasticsearch";
  import "elasticsearch-browser";
  export * from "elasticsearch";
}

Then import elasticsearch from "elasticsearch-browser" anywhere you need to use it.

You've saved my day. For new client lib, just change import elasticsearch from "elasticsearch"; to import "@elastic/elasticsearch"; and export * from "elasticsearch"; to export * from "@elastic/elasticsearch";.

@pootow which folder should the elasticsearch.d.ts be located? I just can't get elastic working in Angular. if you happen to have a small sample I'd be ever so grateful.
