react native hybrid app development

Introduction

It is precise to say that mobile phones have now become an integral part of our day to day life. With regards to Android and iOS enhancements, organizations often get confused with what should they opt or offer their clients. They are in a dilemma to move forward with a multipurpose application with unique User Interface (UI) and amazing User Experience (UX) or applications that are ideal with plentiful stages and are swifter to build in any scenario. With this situation, there comes the REACT Native Development in the depiction.

About React Native

React Native went through an astonishing fame and is sponsored by Facebook. It has an extensive and massive network bolster in the current time. React Native is based on ReactJS which has provided a mammoth rivalry to a long time of top preference, AngularJS. With the piece of information that there are a few likeness and dissimilarity among ReactJS and React Native, which are made with an orientation to underneath, React Native, is a system that builds a chain of command of UI components to erect the JavaScript code. It has a planning and structure of both iOS and Android stages to build a resourceful application with local look and feel.

With ReactJS being an open source JavaScript library supports in making great UIs. Be that as it may, equally React Native and ReactJS are created by Facebook with identical plan standards, to the side from structuring interfaces. As it uses a related code for making REACT Native iOS or the REACT Native Android apps, you merely require knowing the HTML, CSS and the JavaScript. How about we explore the implication of the REACT Native Framework here!

The React Native Framework is known as the Future of Hybrid Apps. Let’s see, What are the reasons behind it?

1) Supports both iOS and ANDROID

Formerly, Facebook just created React Native to be of assistance to iOS platform. Besides, with its partial help to the Android development frameworks and Android working platform. The library would now be able to render versatile UIs for the two stages.

So, Facebook decided to utilize React Native to manufacture its own Ads Manager application, making both an iOS and an Android version. A similar group of engineers worked on the two variants. Facebook additionally made React Native open-source, with the possibility that similarity with different stages like Windows or OS could be chipped away at by the improvement network, so it can remain tuned.

2) Has Reusable Components which enables Hybrid Applications to Render Natively

Gone are the WebView components of other cross breed portable apps. This is feasible in light of the reality that React Native’s building squares are reusable “local segments” that get together purposely to local. Components you would utilize in iOS or Android have partners spot on in React, so you will get a consistent look and feel.

This part based structure furthermore empowers you to fabricate apps with a more quick, web-style way to deal with progression than compared to common half breed solutions, yet with no web by any chance. The application will have the swiftness, look, and expediency of a local portable system.

3) React Native is applied with UI Components To An Alive App’s Code – With No Rewriting At All

This is a massive reward for organizations that require extending an in progress application, however, would have a preference not to update it. Fuse React Native parts into the app’s code. Or on the other hand, if your existing half breed application was built with Cordova and Ionic, you can reuse that Cordova-based code efficiently with a module.

4) React Native is a Top Mobile JavaScript Framework amongst Developers and is continuously Maturing

If you know JavaScript, React Native is a swift pick-up, in effect enabling any of the front-end web developers to be an effective and on the spot mobile developer. No need to become skilled at iOS’s Swift or Java for Android – have knowledge of JavaScript, few of the native UI elements, know integration of platform APIs, and any other specific platform design patterns and you are able to get going. Also, comprised in React Native’s library are Flexbox CSS styling, debugging, inline styling, and support deploying to moreover the Google Play or App Store.

React is growing speedily and Facebook has initiated its advanced plans to carry on investing in its overall expansion.

5) React Native is meant for the Precise and Spot on User Interface (UI)

React Native is persistent exclusively on building a mobile UI. In comparison to JavaScript frameworks like Angular or React, React Native is majorly UI-focused, turning it more like a JavaScript library than an actual framework. The resulting UI is exceedingly responsive and feels fluid all credit to asynchronous JavaScript connections with the overall native environment. This means the application will have more rapid load times than a distinctive hybrid application and a smooth feel.

6) Native Application Development Is Much More Proficient and Competent

While native app development is more often than not connected with inadequacy, lesser developer productivity, and slow time of deployment, React Native is all about enhancing the overall pace and agility of web application development to the overall hybrid space with native outcomes.

Beneath React Native’s hood is Facebook’s trendy ReactJS UI library for different web applications. React Native enables all of ReactJS’s superior app performance, DOM abstraction, and easy programming methodologies to hybrid mobile app development.

7) Enables 3rd party Plugin Compatibility, Lesser Memory Usage and a Better Experience

The 3rd party plugins mean you won’t have to depend on a WebView for specific functions. For example, if you are adding Google Maps features and functionality to your application, React Native lets you connect the plugin with a native module, so you can connect the map up with the device’s specific functions including rotate, zoom, and the compass while using lesser memory and loading rapidly. If your application backs old operating systems, this can assist you to keep the application run very smoothly.

Moving Forward

React Native supports and enables you to make authentic as well as vitalizing applications with the backing of JavaScript. It is compatible with both Android and iOS stages. You just need to code once, and the React Native applications are available for both the iOS and Android stages which spare progression time.

Technostacks is one of the leading IT Company in India, has fruitfully carved its niche within a few years of its commencement. The company is occupied actively in offering comprehensive software solutions to cater to the demands of an assorted clientele across the globe.

iOS unit testing

In General, we will test some parts separately before integrating into something if it’s working or not, otherwise, your full product will be wasted.

Of course not every developer wants to solve the bug after developed the whole App and don’t want to change business logic every time in app and compile the whole project and check results.

Stuck!!! THINK… what’s the solution to save our compile time, Then UNIT Test in the picture.

If you’re reading this iOS Unit Testing tutorial, you already know you should write tests for your code and UI, but you’re not sure how to test in Xcode.

Tests should run quickly, and the developer doesn’t mind by running them.

Let’s Start Testing.

Unit Testing in Xcode

Create new Project File -> New -> Project. Enable both “Include Unit Tests” & “Include UI Tests” when Create you will have Tests files added in your source code.

Unit Testing in Xcode

iOS Unit Testing

The template imports XCTest and defines a UITESTDemoTests subclass of XCTestCase, with setup(), tearDown() and example test methods. Also, it Inherit the XCTestCase class.

Related Article:- The Ultimate Guide For Scanning and Detecting 3D Objects With An iOS App

There are three ways to run the test class.

  • Product\Test or Command-U. This actually runs all test classes.
  • Click the arrow button in the test navigator
  • Click the diamond button in the gutter.

run the test class

The sample tests don’t do anything yet, so they’ll run really fast!

When all the tests succeed, the diamonds will turn green and show check marks. Click the gray diamond at the end of testPerformanceExample() to open the Performance Result:

UI Testing iOS

After the import statement there is “@testable import UITESTDemo”, this gives the unit tests access to the classes and methods in UITESTDemo.

For this blog, we just taking Google API and want to check if Google API working proper or not or any exceed Limit which says have to enter google key to access Lat long details from address.

Source:- maps.googleapis.com

Create API model which will make a network call and give response through closure block. API model code will look like below.

import UIKit

class APIModel: NSObject {

	override init() {

	}

	func jsonCallGET(classURL: String, completionHandler:@ escaping(_result:Any?,_error:Error?) -> Swift.Void)
	{
	    let urlString = classURL
		var request = URLRequest(url: URL(string: urlString)!)
		let session = URLSession.shared
		request.httpMethod = "GET"
		session.dataTask(with: request)
		{
			data, response, error in
			if error != nil
			{
				print(error!.localizedDescription)
				return
			}
			do
			{
			let jsonResult: NSDictionary? = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as? Any as! NSDictionary
			print("Synchronous\(String(describing: jsonResult))")

			if(jsonResult?.value(forKey: "status") as! String == "OVER_QUERY_LIMIT")
				{
					completionHandler(jsonResult?.object(forKey:"data"),error)
				}
				else
				{
					completionHandler(nil, error)
				}
			}
		catch
		{
		print(error.localizedDescription)
		}

		}.resume()
	}
}

Now at the top of the UITESTDemoTests class, add this property:

var APIModelObj : APIModel!
Create object APIModel in setup()
APIModelObj = APIModel()

This creates a SUT (System Under Test) object at the class level, so all the tests in this test class can access the SUT object’s properties and methods.

Before you forget, release your SUT object in tearDown()

APIModelObj = Nil

Now you’re ready to write your first test!

Replace you textExample() method with below.

func testcheckGETAPIcall() {
	// This is an example of a functional test case.
	let url = "http://maps.googleapis.com/maps/api/geocode/json/address=CGroad&sensor=true"
	APIModelObj.jsonCallGET(classURL: url) {
		(result, error) in
		XCTAssertNil(result, "API is not giving any response, please check with your backend developer")
	}

}

Run your test: it should stop at XCTAssertNil with a Test Failure.

Your XCTESTCASE runs successfully but it didn’t wait for the response which will get from the API, Now how can I validate API is working properly or not.

Solution

To test that asynchronous operations behave as expected, you create one or more expectations within your test and then fulfill those expectations when the asynchronous operation completes successfully. Your test method waits until all expectations are fulfilled or a specified timeout expires.

Create an expectation for a background download task in the top of your UITESTDemoTests class.

let expectation = XCTestExpectation(description: “”Check API call”)

Add fulfill statement in your response closer after checking the Assertion in testcheckGETAPIcall(). Fulfill the expectation to indicate that the background task has finished successfully.

Also, need to add Wait statement which will be waiting for the array of expectations created until it will be fulfilled, also we can specify a timeout in that so no response on a longer timer will automatically terminate the XCTEST with Failure.

Your function will look like as below :

func testcheckGETAPIcall() {
	// This is an example of a functional test case.
	let url = "http://maps.googleapis.com/maps/api/geocode/json?address=CGroad&sensor=true"
	APIModelObj.jsonCallGET(classURL: url) { 
		(result, error) in

		XCTAssertNotNil(result, "API is not giving any response, please check with your backend developer")
		self.expectation.fulfill()
	}
	wait(for: [expectation], timeout: 60.0)
}

Run the test. If the API model will return nil it will stop on assertion statement.
That’s it. Stay tuned for UI Test with Xcode.

aws serverless api

How to work with an AWS Serverless API

Just think if your backend had no infrastructure and no permanent server, it sounds a bit isolated, doesn’t it? As it turns out, Serverless backends could subsequently be the coming big thing for advancely implementing robust and scalable cloud architecture.
However, even at present, AWS API’s are utilized in the form of Serverless API.

What is Amazon API Gateway and how to build it?

Amazon API Gateway is an AWS service that empowers developers to build, publish, sustain, maintain, monitor, and secure APIs at all-inclusive scales. You can create APIs that way in AWS and other sorts of web services.
Together with AWS Lambda, API Gateway acts like an app-facing part of the AWS Serverless infrastructure. For an application to call publicly accessible AWS services, you can utilize Lambda to communicate with the needed services and work on the Lambda functions by using API methods in the required API Gateway. AWS Lambda operates and runs the code on a highly accessible computing infrastructure.

How API Gateway assists Developers

API Gateway is built for web and mobile developers who want to offer secure as well as reliable access to backend APIs for access from mobile apps, web apps, and server apps that are created internally or by 3rd party ecosystem partners. A publicly reachable endpoint can offer the business logic that API Gateway proxies call, or it can be utterly run as a Lambda function.

There are two kinds of programmers who utilize API Gateway. The first one is the application developers and the others are API developers. An app developer creates a functioning app to call AWS services by enabling API methods in API Gateway. An API developer develops and deploys an API to empower the needed functionality in the accessible API Gateway. The API developer has to be an IAM user in the AWS account that has the ownership of the API.

Benefits of API Gateway

API Gateway assists you to deliver the best robust, secure, and scalable mobile and web app backends. API Gateway enables you to securely unite mobile and web apps to business logic hosted on AWS Lambda, APIs hosted on Amazon EC2, or other publicly workable web services hosted across AWS.

With API Gateway, you can build and work on APIs for backend services. For instance, you don’t require to create and sustain infrastructure to manage authorization and access control, traffic management, tracking, monitoring and analytics, version management, and software development kit (SDK) generation.

You can further add the DynamoDB table name as an environment variable and fill in the handler name to the specific function name.

Creating an API Gateway with Lambda Integration

To create an API with Lambda integrations, you can utilize both Lambda proxy integration and the
Lambda custom integration. In a broad-spectrum, you must utilize the Lambda proxy integration for an agile and smooth API set up while offering flexible and commanding features.

Lambda proxy integration

With the Lambda proxy integration, the input to the integrated Lambda function can be articulated as any mix of request headers, path variables, query string parameters, and the body. With adding together, the Lambda function can utilize the API configuration settings to control its execution logic.

Lambda custom integration

While having Lambda custom integration, you must make sure that the input to the Lambda function is completed as the integration request payload. This means that an API developer needs to map input data provided as request parameters into the suitable integration request body. You may also require translating the client-supplied request body into a format accepted by the Lambda function.

Below you can view how you can use AWS Lambda to develop a service using Node.js.

Utilization of API Key’s

You can utilize API key to secure your services right from the required unauthorized access. You can configure it within the API Gateway as below.

Stages and Deployment URL:

Once you are all set with our API Gateway and Lambda function, you can easily deploy to “Stage” with deployment URL that is obtainable through the App or Web as below.

Deploy To Stage With URL

The Serverless Web Request

Within a serverless infrastructure, every request matches up to its own server. After the server processes the function, it is straight away destroyed.

Steps for handling a web request:

  • The request comes in by an API Gateway
  • The API request is being properly mapped to a dictionary utilizing Velocity Template Language (VTL)
  • A server is built
  • The server then transforms the dictionary to a customary Python WSGI and feeds it into the required application
  • The application returns it, and it passes it by the API Gateway.
