Coronavirus (COVID-19) in the UK - API Service
Software Development Kit (SDK) for JavaScript
This is a JavaScript SDK for the COVID-19 API, as published by Public Health England on Coronavirus (COVID-19) in the UK.
The API supplies the latest data for the COVID-19 outbreak in the United Kingdom.
The endpoint for the data provided using this SDK is:
https://api.coronavirus.data.gov.uk/v1/data
The SDK is also available for Python and R.
Pagination
Using this SDK will bypass the pagination process. You will always download the entire
dataset unless the latest_by argument is defined.
Installation
Python 3.7+ is required to install and use this library.
To install globally, please run:
npm install -g @publichealthengland/uk-covid19or to install locally in your project, run:
npm install @publichealthengland/uk-covid19Import the library in TypeScript as follows:
import Cov19API from "@publichealthengland/uk-covid19";or using CommonJS:
const Cov19API = require("@publichealthengland/uk-covid19");Example
We would like to extract the number of new cases, cumulative cases, new deaths and cumulative deaths for England using the API.
We start off by importing the library into our workspace:
const Cov19API = require("@publichealthengland/uk-covid19");Next, we construct the value of the filters parameter:
const englandOnly = [
'areaType=nation',
'areaName=England'
];Next step is to construct the value of the structure parameter. To do so, we need to
find out the name of the metric in which we are interested. You can find this information
in the Developer's Guide on the Coronavirus Dashboard website.
In the case of this example, the metrics are as follows:
-
newCasesByPublishDate: New cases (by publish date) -
cumCasesByPublishDate: Cumulative cases (by publish date) -
newDeathsByDeathDate: New deaths (by death date) -
cumDeathsByDeathDate: Cumulative deaths (by death date)
In its simplest form, we construct the structure as follows:
const casesAndDeaths = {
"date": "date",
"areaName": "areaName",
"areaCode": "areaCode",
"newCasesByPublishDate": "newCasesByPublishDate",
"cumCasesByPublishDate": "cumCasesByPublishDate",
"newDeathsByDeathDate": "newDeathsByDeathDate",
"cumDeathsByDeathDate": "cumDeathsByDeathDate"
};Now, we may use filters and structure to initialise the Covid19API object:
const api = new Cov19API({
filters: englandOnly,
structure: casesAndDeaths
});
const data = api.getJSON();
console.log(data)You may also use data.getCSV() to download the data in CSV. This is exemplified later
in this document.
{
'data': [
{
'date': '2020-07-28',
'areaName': 'England',
'areaCode': 'E92000001',
'newCasesByPublishDate': 547,
'cumCasesByPublishDate': 259022,
'newDeathsByDeathDate': None,
'cumDeathsByDeathDate': None
},
{

'areaName': 'England',
'areaCode': 'E92000001',
'newCasesByPublishDate': 616,
'cumCasesByPublishDate': 258475,
'newDeathsByDeathDate': 20,
'cumDeathsByDeathDate': 41282
},
...
],
'lastUpdate': '2020-07-28T15:34:31.000000Z',
'length': 162,
'totalPages': 1
}
To see the timestamp for the last update, run:
const timestamp = api.lastUpdate();
console.log(timestamp);2020-07-28T15:34:31.000Z
To get the latest data by a specific metric, run:
const allNations = [
"areaType=nation"
];
const latestData = new Cov19API({
filters: allNations,
structure: casesAndDeaths,
latest_by: "newCasesByPublishDate"
});
const data = latestData.getJSON();
console.log(data){
"data": [
{
"date": "2020-07-28",
"areaName": "England",
"areaCode": "E92000001",
"newCasesByPublishDate": 547,
"cumCasesByPublishDate": 259022,
"newDeathsByDeathDate": None,
"cumDeathsByDeathDate": None
},
{
"date": "2020-07-28",
"areaName": "Northern Ireland",
"areaCode": "N92000002",
"newCasesByPublishDate": 9,
"cumCasesByPublishDate": 5921,
"newDeathsByDeathDate": None,
"cumDeathsByDeathDate": None
},
{
"date": "2020-07-28",
"areaName": "Scotland",
"areaCode": "S92000003",
"newCasesByPublishDate": 4,
"cumCasesByPublishDate": 18558,
"newDeathsByDeathDate": None,
"cumDeathsByDeathDate": None
},
{
"date": "2020-07-28",
"areaName": "Wales",
"areaCode": "W92000004",
"newCasesByPublishDate": 21,
"cumCasesByPublishDate": 17191,
"newDeathsByDeathDate": None,
"cumDeathsByDeathDate": None
}
],
"lastUpdate": "2020-07-28T15:34:31.000000Z",
"length": 4,
"totalPages": 1
}
You may retrieve CSV-formatted data as follows:
const csvData = api.getCSV();
console.log(csvData)date,areaName,areaCode,newCasesByPublishDate,cumCasesByPublishDate,newDeathsByDeathDate,cumDeathsByDeathDate
