The package provides an API Client for use with Scramjet Transform Hub.

Usage:

```js
import { HostClient, SequenceClient } from "@scramjet/api-client";

const host = new HostClient("http://192.168.0.34:8000/api/v1");

host.getSequence("3e989fe7-a3b7-401e-a269-2fa0a7ac70f4")
```

## Scramjet Transform Hub

This package is part of [Scramjet Transform Hub](https://www.npmjs.org/package/@scramjet/sth).

Scramjet Transform Hub is a deployment and execution platform. Once installed on a server, it will allow you to start your programs and keep them running on a remote machine. You will be able to start programs in the background or connect to them and see their output directly on your terminal. You will be able to pipe your local data to the program, as if it was running from your terminal. You can start your server in AWS, Google Cloud or Azure, start it on your local machine, install it on a Raspberry Pi or wherever else you'd like.

## Use cases

There's no limit what you can use it for. You want a stock checker? A chat bot? Maybe you'd like to automate your home? Retrieve sensor data? Maybe you have a lot of data and want to transfer and wrangle it? You have a database of cities and you'd like to enrich your data? You do machine learning and you want to train your set while the data is fetched in real time? Hey, you want to use it for something else and ask us if that's a good use? Ask us [via email](mailto:get@scramjet.org) or hop on our [Scramjet Discord](https://scr.je/join-community-mg1)!

### Service Discovery: Topics

If a given topic does not exist, Transform-Hub creates it and stores the sent data in the newly created topic. The data is stored in the topic until the data is not consumed (either by the Topic API or by the Instances subscribing to this topic). When the data are sent to the topic they are written to the returned stream.
