## Architecture 

![architecture](assets/Highlevel-arch.jpg)  

## Features 

- Builds an Elastic Serverless project via REST API

- Creates a client via the Javascript library

- Performs the following steps with the Javascript client:

    - Creates an Inference Endpoint to an Azure Openai embedding model

    - Creates an index mapping corresponding to a dataset in this repo

    - Bulk loads the included JSON lines dataset (1000 documents).  This Kaggle [dataset](https://www.kaggle.com/datasets/rmisra/news-category-dataset) was used.

    - Performs a sample semantic search against this dataset

- Deletes the Elastic Serverless project

## Prerequisites 

- Elastic Cloud account and API key

- Azure Openai resource and API key

- node

- npm

## Installation 

- Execute the command below

```bash

git clone git@github.com:joeywhelan/serverless-js.git && cd serverless-js && npm install
