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.
npm install metoffice-datapoint
Usage
The module needs to be instantiated with an API key from Met Office DataPoint.
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, ...)
const winston = require('winston')
logger = winston.createLogger({
transports: [new winston.transports.Console()]
})
{Observations, Forecast} = datapoint(apiKey, logger)
