Thingful node.js Client

This package provides a client for the REST API provided by the IoT search engine, thingful.net.

The project was developed by 1248 and is released under the Apache 2.0 license.

Thingful

This is a factory that allows creation of one, or many ThingfulClients to be used for making queries to the Thingful API.

thingful.createClient()

Returns a new instance of ThingfulClient.

Example:

var thingful = require('thingful');

var client = thingful.createClient();

ThingfulClient

The ThingfulClient is a container for making Thingful API calls, containing information about the current query, paging data and array of Things. The properties can be accessed directly through the object, or the query() shortcut method can be used to fill in the required queryString and bounds properties.

// Set some properties
client.currentQuery = 'QUERY STRING';
client.bounds = {
	minLat: 51.12,
    maxLat: 52.11,
    minLon: 0.12,
    maxLon: 0.15
};
client.limit = 100; // Number of results per page

// The things array will be an empty array as default, but as
// queries are run this will be populated
console.log(client.things);

ThingfulClient.execute()

ThingfulClient.query(queryString, bounds)

Shortcut method to add the required properties to the ThingfulClient object and then run execute() to populate the Things array and paging data.

client.query('temperature', {
    minLat: 51.12,
    maxLat: 52.11,
    minLon: 0.12,
    maxLon: 0.15
}).then(function(res) {
    // "res" is just returning the original client with the populated data
    console.log(res.things);
});

ThingfulClient.next()

Thingful.Thing

Examples

A simple query

// Make the query
client.query('temperature', {
	minLat: 51,
	maxLat: 52,
	minLon: 0,
	maxLon: 1
}).then(function(res) {
	// Resulting things should now be in res.things
	console.log(res.things);
});

A query that makes use of next()

var things = [];

client.query('temperature', {
	minLat: 51,
	maxLat: 52,
	minLon: 0,
	maxLon: 1
}).then(function(res) {
	things.concat(res.things);
	return res.next();
}).then(function(res) {
	things.concat(res.things);
	// "things" should now contain all things from the first and second page
});
