  • Pros and cons of vue js
    Vue.js – is a JavaScript-framework that uses the MVVM pattern for creating user interfaces based on data models through reactive binding data.
  • A developer might not know how to use it but he should have heard about Vue js, because the framework became popular in past few years the number of use the words “Vue js” and “Vue.js” in Google trend in 2016 was more than in four times higher comparing to 2015.
  • Advantages of vue js:

    Having borrowed from older frameworks, such as Angular and React only the best, Vue.js stands the perfect balance between readability, maintainability of code and the pleasure of it, this code, writing.

  • From React Vue.js took a component approach, props, one-way data flow for the component hierarchy, performance, the ability to render on the backend and understanding the importance of proper state management.
  • This makes it easy to add the Vue library to the project, like jQuery.All this is possible in the React library, but generally the code written on React relies more on JSX and on the features of ES.

Both React.js and Vue.js have benefits and disadvantages, that may confuse a potential client at first. We’re going to make their comparison in this article.

  • The client uses reagent for the view, cljs-http for making REST calls, and sente for the socket connection.
  • Any result obtained or process described is simply the application of rules to facts unless otherwise stated.
  • We have written a rule rule matches on it and makes REST calls to fetch the cart and a list of products from the server.
  • Because its eid is , there is some magic here, as Precept auto-retracts any fact with the eid of at the end of every session, ensuring such facts survive one rule firing only.
  • When a response from the server is received, facts are inserted into the session, rules fire, state advances, and views update.

How to Scan Fingerprints with Async PHP and React Native — SitePoint

How to multi-factor authentication with Fingerprints scans, Async PHP and React Native

  • Our composer.json file could look something like:
    {
    “scripts”: {
    “dev”: “vendor/bin/aerys -d -c loader.php”,
    “prod”: “vendor/bin/aerys -c loader.php”
    },
    “require”: {
    “amphp/aerys”: “dev-amp_v2”,
    “pre/kitchen-sink”: “^0.1.0”
    },
    “autoload”: {
    “psr-4”: {
    “App\\”: “app”
    }
    },
    “config”: {
    “process-timeout”: 0
    },
    “minimum-stability”: “dev”,
    “prefer-stable”: true
    }

    This is from composer.json in the server project

    We can also set up a placeholder for requesting scans, along with an HTTP GET route to get to it:
    namespace App\Action;

    use Aerys\Request;
    use Aerys\Response;

    class ScanAction
    {
    public function __invoke(Request $request, Response $response)
    {
    $response-end(“requesting a scan…”);
    }
    }

    This is from app/Action/ScanAction.

  • pre in the server project

    use Aerys\Router;
    use App\Action\ScanAction;

    return (Router $router) = {
    $router-route(
    “GET”, “/scan”, new ScanAction
    );
    };

    This is from routes/web.

  • pre in the server project

    And we can start the server up with a server config file and pre-processor loader script:
    $port = 8080;

    $host = new $port);

    $host-use($router = Aerys\router());

    $web = process ‘http://127.0.0.1:{$port}’ | pbcopy”);

    This is from config.pre in the server project

    return Pre\processAndRequire(__DIR__ . “

  • Let’s add web sockets to our server:
    namespace App\Socket;

    use Aerys\Request;
    use Aerys\Response;
    use Aerys\Websocket;
    use Aerys\Websocket\Endpoint;
    use FingerprintSocket implements Websocket
    {
    private $endpoint;
    private $connections = [];

    public function onStart(Endpoint $endpoint)
    {
    $this-endpoint = $endpoint;
    }

    public function onHandshake(Request $request,
    Response $response)
    {
    // $origin = $request-getHeader(“origin”);
    //
    // if ($origin !

  • == “http://127.0.0.1:8080”) {
    // $response-setStatus(403);
    // $response-end(“origin not allowed”);
    // return null;
    // }

    $info = return $info[“client_addr”];
    }

    public function onOpen(int $clientId, $address)
    {
    $this-connections[$clientId] = $address;
    }

    public function onData(int $clientId, Message $message)
    {
    $body = yield $message;

    yield $this-endpoint-send(
    $payload, $clientId
    );
    }

    public function onClose(int $clientId,
    int $code, string $reason)
    {
    }

    public function onStop()
    {
    // nothing to see here…
    }
    }

    This is from in the server project

    use Aerys\Router;
    use App\Action\ScanAction;
    use (Router $router) = {
    $router-route(
    “GET”, “/scan”, new ScanAction
    );

    $router-route(
    “GET”, “/ws”, Aerys\websocket(new FingerprintSocket)
    );
    };

    This is from routes/web.

Why Use React JS for Fast Interactive User Interfaces? — SitePoint

  • The Virtual DOM is at the core of what makes React fast at rendering user interface elements and their changes.
  • Each time there are changes to the underlying data in a React app, React creates a new Virtual DOM representation of the user interface.
  • This is where efficient diff algorithms, batching DOM read/write operations, and limiting DOM changes to the bare minimum necessary, make using React JS and its Virtual DOM a great choice for building performant apps.
  • Our First 50,000 Stars — Vjeux

    Although some would argue that all projects need React JS, I think it’s uncontroversial to say that React would be a great fit for web apps where you need to keep a complex, interactive UI in sync with frequent changes in the underlying data model.

  • Resources
    If you’re curious about how React JS and its Virtual DOM work, here’s where you can learn more:

    Conclusion
    React JS and other similar JavaScript libraries ease the development of snappy, event-driven user interfaces that are fast at responding to state changes.

Maria Antonietta Perna discusses what makes React JS a great fit for building fast UIs and introduces the concept of the Virtual DOM and how React uses it.

A Year of React Native: SSL Pinning – Made by Many

Notes on #ReactNative: on SSL pinning by @samueljmurray

  • When your app initiates this communication, your backend sends its certificate (which contains the public key).
  • Your app then checks that the certificate has been signed by a Certificate Authority (CA) that is trusted by the user’s device.
  • SSL pinning narrows these avenues of attack by letting you define the exact certificate or public key that your app will accept when communicating with your backend.
  • If you use a service like AWS Certificate Manager or Let’s Encrypt your certificate and public key could change at any time.
  • TrustKit also comes with a handy tool for extracting public keys from certificates and converting them to Base64 encoded SHA256 hashes.

We’ve been using React Native for over a year now and we’re loving how quickly we can create feature-rich and performant apps for iOS and Android. So far w…

How to Scan Fingerprints with Async PHP and React Native

  • In an amazing article on SitePoint, Christopher Pitt demonstrates how to create an async PHP server that can requests a fingerprint scan on the client side.
  • He uses React Native, WebSocket, an async PHP server, PHP preprocessing, … Really amazing stuff.
  • We will also set up an asynchronous HTTP server, with a web socket connection to the app.
  • We will follow this up by adding fingerprint scanning capabilities to the app, and asking for these fingerprint scans from the HTTP server.
  • Then we will build an endpoint through which GET requests can request a fingerprint scan and wait for one to occur.
