# node-red-contrib-twc-covid19-tracker
Node-RED node for The Weather Company (TWC) COVID-19 Disease Tracking API

These nodes implements the [TWC APIs for COVID-19 Disease Tracking](https://weather.com/swagger-docs/ui/sun/v3/sunV3DiseaseTracker.json).

The API allows you to track the progression of a disease for a given location.  It provides information regarding active diseases including confirmed cases, deaths, and recoveries over a period of up to 60 days in the past.

## Install

Either use the Editor - Menu - Manage Palette - Install option, or run the following command in your Node-RED user directory (typically `~/.node-red`).
```
$ npm install node-red-contrib-twc-covid19-tracker
```

## Register

To use **The Weather Company API for COVID-19 Disease Tracking**, you need an **API key**.  [Call for Code](https://developer.ibm.com/callforcode) participants can register to join the [Call for Code 2020 COVID Challenge](https://developer.ibm.com/callforcode/getstarted/covid-19/) and request a TWC API key for this Node-RED node at [callforcode.weather.com](https://callforcode.weather.com) A time-limited API key will be sent to you via email.

## node-red-contrib-twc-covid19-tracker Nodes

This Node-RED package creates **twc covid19 tracker** and **twc covid19 country report** nodes in your Node-RED palette.
- **twc covid19 tracker** - Query 60 day history of COVID-19 statistics at the Country, State, County level by Geocode, Place ID or Postal Code.
- **twc covid19 country report** - Query the current state of a disease for a set of countries globally.

Review the [CHANGELOG](https://github.com/call-for-code/node-red-contrib-twc-covid19-tracker/blob/master/CHANGELOG.md) for enhancement history.

### Explore the node-red-contrib-twc-covid19-tracker Node-RED node

Once the node is installed in your Node-RED palette, drag it to your flow and double-click on the **twc covid tracker** node. In the **Properties** dialog box enter the following information:

* Your TWC API Key provided by [callforcode.weather.com](https://callforcode.weather.com)
* Specify whether the node will retrieve **country**, **state** or **county** COVID-19 data
* Specify the location you are interested in; **geocode** latitude/longitude, **Place ID**, or **Postal Key**
* The location either via latitude/longitude, place id or postal code.  Examples:
  * 40.74,-73.99
  * 327145917e06d09373dd2760425a88622a62d248fd97550eb4883737d8d1173b
  * 10001:US

Review the node information documentation in the Node-RED right hand side bar for techniques that allow you to programmatically pass in the above parameters via a *msg.twcparams* json object.

## Review the TWC Disease Tracker API documentation

The Weather Company offers [TWC Weather Data Packages](https://business.weather.com/products/weather-data-packages) that are available for purchase. The Node-RED node in this package implements the Disease Tracking API service and is free for Call for Code participants (please review the [Terms of Service](https://callforcode.weather.com/register/))

The TWC Disease Tracker API allows you to track the progression of the COVID-19 disease for a given location. It provides information regarding active diseases including confirmed cases, deaths, and recoveries over a period of up to 60 days in the past.

See the [online documentation](https://weather.com/swagger-docs/ui/sun/v3/sunV3DiseaseTracker.json) for more information about The Weather Company API for Disease Tracking.

See the [online documentation](https://weather.com/swagger-docs/ui/sun/v3/sunV3DiseaseTrackerCountryList.json) for more information about The Weather Company API for Global Disease Country Reporting.

The APIs returns an array of json objects containing COVID-19 data which you can integrate into dashboards or applications.

## Tutorials

For a full tutorial with instructions, screenshots and examples, review the IBM Developer
[Build a Node-RED COVID-19 dashboard](https://developer.ibm.com/tutorials/build-a-node-red-covid-19-dashboard-using-twc-disease-tracker-api/) tutorial.

## Examples

Learn how to implement a Node-RED COVID-19 statistics dashboard using The Weather Company Disease Tracker API.

Access COVID-19 location and infection data through an API provided by **The Weather Company** (TWC) and incorporate that data in
Node-RED dashboard, charts, and tables. Use Node-RED for data analysis and data visualization of COVID-19 infections
by country, state and county.

Four examples are provided in the [examples](https://github.com/call-for-code/node-red-contrib-twc-covid19-tracker/tree/master/examples) folder.

___
#### Example #1

#### Example #4

- This example Node-RED Dashboard displays all of the States in the USA in a table and, for the selected state, plots 60 days of COVID-19 historical data on a chart.  It also plots a chart of new cases reported each day and a seven day moving average that demonstrates flattening the curve or states that have recurrent
outbreaks.  It also drops pins with state metrics on a map.  To determine the latitude/longitude of the state, it uses a TWC location API - reuse your TWC api key.

- [Install Node-RED](https://nodered.org/docs/getting-started/) on your system or in the cloud
  - This flow can be deployed to [IBM Cloud](https://cloud.ibm.com/registration) by creating a [Node-RED Starter Application](https://developer.ibm.com/components/node-red/tutorials/how-to-create-a-node-red-starter-application/)
- This flow requires Node-RED v1.1 or higher

![COVID-19 Dashboard](https://raw.githubusercontent.com/Call-for-Code/node-red-contrib-twc-covid19-tracker/master/screenshots/Node-RED-COVID19-States-Dashboard-flow.png)
![COVID-19 Dashboard](https://raw.githubusercontent.com/Call-for-Code/node-red-contrib-twc-covid19-tracker/master/screenshots/Node-RED-COVID19-States-Dashboard.png)

This flow has four sections:
1. The **Load State Table** section displays a Node-RED Dashboard button widget, a Template node which contains a CSV list of States and zip codes, and a CSV node which splits the state list into individual messages.
1. The **Query COVID Stats for all 50 States** section calls the [TWC Disease Tracking API](https://weather.com/swagger-docs/ui/sun/v3/sunV3DiseaseTracker.json) to retrieve the COVID19 infection data for each state.  It builds an array of states and their COVID19 stats.
1. The **Build Charts and Tables** section displays a table of states with sortable COVID19 stats.  When a user selects a state, the 60 days of COVID-19 historical data is displayed on a chart and table.  It also plots a chart of new cases reported each day and a seven day moving average that demonstrates flattening the curve or states that have recurrent outbreaks.
1. The **COVID Map of USA** section determines the latitude/longitude of the state by using a [TWC Location Search API](https://weather.com/swagger-docs/ui/sun/v3/sunV3LocationSearch.json) call.  It then drops pins with state COVID19 metrics on a map.
