planetos

Access the Planet OS API with your Node.js app.

• Node.js
• Package on npm
• Planet OS
• API documentation

Example

const planetos = require ('planetos') ({
  apikey: 'abc123'
});

// NOAA Wave Watch 3 data
const params = {
  lon: -50.5,
  lat: 49.5,
  count: 1,
  context: 'reftime_time_lat_lon'
};

planetos ('noaa_ww3_global_1.25x1d', params, console.log);

Installation

This module requires an API key from Planet OS. You can find it in your account settings.

npm install planetos

Configuration

The module takes the following settings:

param	type	required	default	description
apikey	string	yes		Your API key
timeout	number	no	5000	Request timeout in ms
endpoint	string	no	Planet OS	Override default API endpoint (i.e. proxy)

const planetos = require ('planetos') ({
  apikey: 'abc123',
  timeout: 10000,
  endpoint: 'https://my.proxy/http://data.planetos.com/v1'
});

API call

The function takes these arguments:

argument	type	required	description
dataset	string	yes	Dataset name, i.e. noaa_ww3_global_1.25x1d
params	object	yes	Dataset query parameters
callback	function	yes	function (err, data) {}

// Process results
function myCallback (err, data) {
  if (err) {
    return console.log (err);
  }

  console.dir (data, {
    depth: null,
    colors: true
  });
}

// Query parameters
const params = {
  lon: -50.5,
  lat: 49.5,
  count: 1,
  context: 'reftime_time_lat_lon'
};

// Request data from API
planetos ('noaa_ww3_global_1.25x1d', params, myCallback);
