Time to play some IoT with relayr / Wunderbar

IoT is the current buzz word and I will be doing some more tinkering with current solutions this year. I have done projects with Arduino , Raspberry Pi and looking into relayr / Wunderbar right now.

relayr provides a tech stack with Wunderbar, that easily connects included sensors with the cloud. They provide a wide range of API endpoints to collect data and even integrate hardware solutions like Arduino orRaspberry Pi.

“The WunderBar is built for software developers. It is a powerful rapid prototyping and product development tool that enables developers to immediately start creating products and solutions that utilise the Internet of Things, without any prior hardware knowledge. No soldering or electronic engineering experience is needed. Just choose what sensors you need for your project and start coding.”

Starterkit should arrive next week …

My Javascript Stack

Some time ago I said: “My perfect framework, is a set of solid singular solutions that have proven themselves over the years. Working solo or together in harmony”.

Here is a list of some of my core components, that I use in combination or standalone.

CORE

jQuery – jquery.com
Underscore – underscorejs.org
Directives – github.com/mennovanslooten/jquery.directive.js

LAYOUT

Bootstrap – getbootstrap.com

TEMPLATING

jQuery loadTemplate – github.com/codepb/jquery-template
OR
jsViews / jsRender – jsviews.com/#jsrender

OBSERVABLES

jsViews Observable – jsviews.com/#jsoapi

ROUTER

Director – github.com/flatiron/director

STORAGE

simpleStorage – github.com/andris9/simpleStorage

DEPENDENCY MANAGER

RequireJS – requirejs.org
jQuery Tweak: If you have already loaded jQuery before RequireJS, you can not use define([“jquery”], …) in your module defines. Add this to your main RequireJS config before doing anything else …

define('jquery', [], function() { return jQuery; });

1
2
3

define('jquery', [], function() {
return jQuery;
});

NOW you can live happily ever after :)
OR
Loadrunner – github.com/danwrong/loadrunner

This is basically the core stack that I use to build out ideas :) While Angular is always an option, the above satisfies most of all needs and is often far slimmer. The rest depends on how you organize your code yourself, but at least you are not forced into fixed structures ;)

Hybridauth 3.0 Remake – social logins made easy

“Hybridauth enables developers to easily build social applications and tools to engage websites visitors and customers on a social level by implementing social sign-in, social sharing, users profiles, friends list, activities stream, status updates and more.

The main goal of Hybridauth is to act as an abstract API between your application and various social apis and identities providers such as Facebook, Twitter and Google.”

Hybridauth 2.x was the best option for nicely aggregated social logins so far, but some of the social “Providers” are outdated or no longer working. Version 3.0 is still in development, but providing a complete rewrite.

  require 'vendor/autoload.php';

    $config = [
        'callback' => 'http://localhost/hybridauth/examples/twitter.php',

        'keys' => [ 'key'    => 'your-consumer-key', 'secret' => 'your-consumer-secret' ]
    ];

    $twitter = new Hybridauth\Provider\Twitter( $config );

    try {
        $twitter->authenticate();

        $userProfile = $twitter->getUserProfile();

        $accessToken = $twitter->getAccessToken();

        $apiResponse = $twitter->apiRequest( 'statuses/home_timeline.json' );
    }
    catch( Exception $e ){
        echo "Ooophs, we ran into an issue! " . $e->getMessage();
    }

require 'vendor/autoload.php';

$config = [

'callback' => 'http://localhost/hybridauth/examples/twitter.php',

'keys' => [ 'key' => 'your-consumer-key', 'secret' => 'your-consumer-secret' ]

];

$twitter = new Hybridauth\Provider\Twitter( $config );

try {

$twitter->authenticate();

$userProfile = $twitter->getUserProfile();

$accessToken = $twitter->getAccessToken();

$apiResponse = $twitter->apiRequest( 'statuses/home_timeline.json' );

}

catch( Exception $e ){

echo "Ooophs, we ran into an issue! " . $e->getMessage();

}

For Facebook , Twitter and Google+ I still use my own little wrappers, but if you want more this is the way to go in the future :)

Headless WordPress with the HTTP REST API 2.0+

Using WordPress as a headless system, is nothing new. You can easily build out your own REST API or use the long available HTTP REST API 1.0+ for WordPress.

But with the new HTTP REST API 2.0+ its getting really easy to build out your own REST API Namespace and assign routes for all your JSON needs.

The new REST API will make its appearance in WordPress 4.4, but you can start now by adding the plugin to your system. When the plugin detects 4.4+ it will only load functionality not already present in the core.

A ROUTE

A route tells the API to respond to a given request with a specific function (endpoint). This adds the permalink structure to WordPress so that your functionality can be accessed via an url like this: http://yourdoman.com/wp-json/yourplugin/v1/myfunction/your_parameter

add_action( 'rest_api_init', function () {
    register_rest_route( 'your_namespace/v1', '/your_endpoint/(?P<your_parameter>\d+)', array(
        'methods' => 'GET',
        'callback' => 'your_endpoint',
    ) );
} );

add_action( 'rest_api_init', function () {

register_rest_route( 'your_namespace/v1', '/your_endpoint/(?P<your_parameter>\d+)', array(

'methods' => 'GET',

'callback' => 'your_endpoint',

) );

} );

THE ENDPOINT

The Endpoint is the callback handled by the route. Each endpoint can have additional parameters attached:

custom permissions
default values
sanitization callback
validation callback
field requirements and more

RETURN VALUE

The return values from the endpoint are converted into JSON. You can use the WP_REST_Response object , this wraps normal body data and allows you to return a custom status code.

function your_endpoint( $data ) {
    $posts = get_posts( array(
         'author' => $data['your_parameter'],
    ) );

    if ( empty( $posts ) ) {
        return new WP_Error( 'your_endpoint_no_data', 'No Data', array( 'status' => 404 ) );
    }

    return new WP_REST_Response( $posts, 200 );
}

function your_endpoint( $data ) {

$posts = get_posts( array(

'author' => $data['your_parameter'],

) );

if ( empty( $posts ) ) {

return new WP_Error( 'your_endpoint_no_data', 'No Data', array( 'status' => 404 ) );

}

return new WP_REST_Response( $posts, 200 );

}

Really powerful stuff, that makes it easy to detach WordPress and the actual client using the data provided by it.
