Met Office Datapoint

A JavaScript module for accessing weather data via the Met Office's legacy open data API known as DataPoint.

Disclaimer: This module is in no way part of the DataPoint service or otherwise affiliated with the Met Office in any way

Features

* Retrieve a list of sites providing observations
* Retrieve a list of timesteps that observations are available for
* Retrieve observation data for site(s)
* Retrieve a list of sites that forecast data is avaialble for
* Retrieve a list of timesteps that forecast data is available for
* Retrieve forecast data for site(s)

Installation

The module can be directly installed via npm or yarn, e.g.

``bash
npm install metoffice-datapoint
`

Usage

The module needs to be instantiated with an API key from Met Office DataPoint.

`javascript
const datapoint = require('metoffice-datapoint')
const apiKey = '01234567-89ab-cdef-ghij-klmnopqrstuv' // API Key
{Observations, Forecasts} = datapoint(apiKey)
`

The module can additionally be instantiated with a logging object to produce logging messages. The logging object is expected to contain methods for error, warn, info, trace, and debug (i.e. winston, log4js, ...)

`javascript
const winston = require('winston')
logger = winston.createLogger({
transports: [new winston.transports.Console()]
})

{Observations, Forecast} = datapoint(apiKey, logger)
`

### Observations

#### Sitelist

`javascript
Observations.sitelist()
.then((sites) => {
console.log(sites)
})
`

#### Capabilities

`javascript
Observations.capabilities()
.then((timestep) => {
console.log(timestep) // Timesteps are Date objects
})
`

#### Values

`javascript
Observations.values()
.then((reports) => {
console.log(reports)
})
`

$3

#### Sitelist

`javascript
Forecast.sitelist()
.then((sites) => {
console.log(sites)
})
`

#### Capabilities

`javascript
Forecast.capabilities()
.then((timestep) => {
console.log(timestep) // Timesteps are Date objects
})
`

#### Values

`javascript
Forecast.values()
.then((reports) => {
console.log(reports)
})
