feathers-openweathermap

Ever needed weather information in your feathers.js app? No matter if historical, current or forecast data. This is thin layer around the OpenWeatherMap API wrapped in a feathers.js service.

Supported APIs

• Current weather (free)
• Onecall (free)
• Forecast (free)
• Hourly forecast (Included in the Developer, Professional and Enterprise subscription plans)
• Daily forecast (Included in all paid subscription plans)
• Climatic forecast (Included in the Developer, Professional and Enterprise subscription plans)
• Air pollution (free)

Installation

npm install feathers-openweathermap

Get your appid

Follow the instructions at: https://openweathermap.org/appid

Creating a service

const { Service } = require('feathers-openweathermap');

app.use("/weather", new Service({
  appid: "YOUR_APP_ID",
}))

Service options

• appid (required) - your appid from openweathermap.org
• v (optional, default: '2.5') - the version of openweathermap
• mode (optional, default: 'json') - the results format (possible: 'json', 'xml', 'html')
• lang (optional, default: 'en') - the language of the result. info
• units (optional, default: 'standard') - Units of measurement. 'standard', 'metric' and 'imperial' units are available.

Methods

The service exposes two standard methods, find(params) and create(data, params) and custom methods for @feathersjs/feathers@5. These methods are functionally equivalent. The create() method is added so that you can take advantage of the .on('created') service event.

When using the find(params) method, include the query as the params to be passed to the underlying OpenWeatherMap method.

Testing

Simply run npm test and all your tests in the test/ directory will be run. This project is setup with vscode. You can use the debugger with breakpoints. To run tests locally, you'll need your own appid. You can get it here: https://openweathermap.org/appid. Add a .env file with:

APPID = YOUR_APP_ID
