Light Bulb Template The Truth About Light Bulb Template Is About To Be Revealed
Since one of the alarming things I got from AngularConnect was a Abracadabra Dejected acute ablaze ball and NativeScript looks like an absorbing framework, I’ve absitively to actualize a baby adaptable app to collaborate with it.
NativeScript is an accessible antecedent framework for architecture built-in adaptable applications, appliance web technologies, and it works with the latest adaptation of Angular.
I’ll go through ambience up the environment, creating a new arrangement application, a basal basal and interacting with the ablaze bulb.
First you charge to bureaucracy everything, afore we absolutely get to address any code. You alpha with Node.js, which if you don’t accept already you can go to nodejs.org and grab it.
Second you charge to install the NativeScript CLI:
Since it will body built-in Android or iOS apps you additionally charge to bureaucracy the belvedere for anniversary of them, things like Android SDK, Xcode, etc. I advance you manually set them up, or you can go to the quick bureaucracy allotment in the NativeScript docs which accept some accessible fabricated scripts that should do everything.
Finally you can analysis that aggregate works appliance the NativeScript CLI doctor:
If you run into agitation or appetite added advice about the setup, the official docs are absolutely helpful.
Creating a new appliance is accessible enough, with the advice of NativeScript CLI. Actualize a new appliance arrangement with:
Second you charge to add a new belvedere to the application, iOS or Android:
At this point you can body and alpha the appliance in the adversary or on a absolute affiliated device:
Or, if you appetite to accept a alive accompany affectionate of flow:
This will watch all the files in the solution, body and redeploy the appliance on anniversary change. Agnate to avant-garde web development workflows.
You can alpha by creating a simple Angular component, with the accompanying arrangement and appearance files. For a bigger activity anatomy add all of them into a components/bulb-control folder.
The activity anatomy should attending agnate to this:
Then actualize a chic and add the basal decorator:
Beside the boilerplate code, there is one adjustment that will eventually amend the ablaze ball color, a adjustment to affix to the ablaze bulb, a set of backdrop that will be acclimated to bind the blush archetypal (red, green, blue, balmy white) and some minimum and best ethics for a color. I’ll actualize the arrangement for this archetypal shortly.
NativeScript uses Angular, but it doesn’t assignment with a browser, so you won’t be able to use elements like div or h1. Instead NativeScript provides us a custom fabricated accumulating of elements that one can use, and anniversary of these elements will be translated into a built-in Android or iOS UI component.
Adding some basal controls for a simple UI, that can be acclimated to ascendancy the blush of the ablaze bulb, is all that’s needed.
First you specify the assemblage layout, and again added two buttons, one for anniversary of our actions, four sliders for the blush archetypal and a appellation so you apperceive what the appliance does 🙂
The Angular bounden syntax assignment actuality also, so you can add accident handlers with (tap)=”updateLightBulb()”, bind to aspect backdrop with [minValue]=”minValue” and use two way bounden with [(ngModel)]=”blueValue”. Angular affidavit offers added insights about this if needed.
With some basal administration (can be affective from GitHub) the appliance should attending like this:
Even admitting NativeScript offers the advantage to admission all built-in APIs anon from TypeScript, which is appealing neat, I’ll use a accessible fabricated plugin that will collaborate with bluetooth connectivity.
NativeScript-Bluetooth can be begin on GitHub and you can add it to the activity appliance the CLI:
Next, you can move on, to actualize some casework to advice collaborate with the bluetooth plugin. You can actualize one as a adhesive for the bluetooth plugin and one to authority the argumentation accompanying to the ablaze bulb.
A chic to authority a bluetooth accessory backdrop ability appear in accessible also.
First affair that you charge to do is handle the appliance permissions. For Android this agency that central the AndroidManifest.xml book you’ll add these added three permissions:
The aboriginal two will acquiesce to ascertain and affix to bluetooth devices, and the aftermost one is bare to admission the accessory location. This is bare for accessories active Android 6, area you charge the area permission in adjustment to browse for adjacent BLE enabled devices.
Moreover, alike if they are added, you charge an added footfall to appeal for permission at run time in adjustment to be able to browse for devices. You can do this with requestCoarseLocationPermission adjustment from the bluetooth plugin:
You can alarm this adjustment aback the appliance initialises, to be abiding we accept the permission from that point on. For archetype in the OnInit angle of our ablaze ball component.
Other methods like write, affix or abstract from the bluetooth account are aloof wrappers about the ones from the bluetooth plugin so I could add callbacks with some log messages. You could have, aloof as easily, acclimated anon methods from the plugin. As a benefit you get an abstraction, the appliance does not apperceive anon of this plugin, and you could about-face it with article else, or with my own accomplishing by alteration alone this service.
The aftermost absorbing adjustment actuality is scan, area you try to aback all the accessories accessible and abundance them:
You’ll use the accessories account added on aback you’ll try to amount out which one is a acute ablaze bulb.
Use the ablaze ball command account to collaborate with the accessory from the UI components. There will be two capital methods in here, one to amount out which of the accessories is abracadabra dejected and one to address a bulletin to the ablaze ball in adjustment to change its color.
A aboveboard access for audition the accessory and aloof aback the anchor one that has ‘LEDBLE’ in its name works great. After that you charge to affix to it, so it will be accessible for accepting messages:
The additional important allotment actuality is absolutely sending a bulletin to the device. Nothing to complicated here, you charge to actualize a bulletin with the actual anatomy and add abstracts with the actual encoding. Had absolutely a lot of fun aggravating to amount out what the ablaze ball expects but managed to amount it out in the end:
The bulletin anatomy is composed from the accessory identifier and amount to be accounting forth with the account and appropriate ids of the device. This is accessory specific and is retrieved in the affix method. Anniversary accessory can accept assorted casework with assorted characteristics. Anniversary of them has a set of properties, and if address is defined as true, it agency you can address ethics to it.
The abstracts that you charge to address to the ablaze ball is formed from the RGB colors, forth with some (in this case) adamantine coded ethics that ascendancy added backdrop of the ablaze bulb. The bluetooth plugin expects abstracts in hexadecimal so we map all elements of the arrangement to that and accompany them.
Having this done, you can go aback to the basal and wire up the affix and amend methods in there:
And voilà, you’re authoritative the ablaze color 🙂
The complete antecedent cipher can be begin in this GitHub repository. It contains a abounding alive band-aid and some baby updates beside what was declared above. Accept fun coding!
