Kotlin solves this problem in a flexible way by providing coroutine support at the language level and delegating most of the functionality to libraries.

Let say we have a file at certain URL and to read that file we are taking the help of Coroutines.

All you need to do is launch it within a coroutine context, like this


Job interviews. A necessary evil. Most candidates break out in a cold sweat at the mere thought. How do I prepare? What are they going to ask me? What should I ask them? Those are just a few of the questions that run through the mind of the average interviewee.

React-native+Expo camera

expo-camera provides a React component that renders a preview for the device's front or back camera. The camera's parameters like zoom, auto focus, white balance, and flash mode are adjustable. With the use of Camera, one can also take photos and record videos that are then saved to the app's cache. Morever, the component is also capable of detecting faces and bar codes appearing in the preview.

Initialising the Project

ISS Location

Many mobile apps need to load resources from a remote URL. You may want to make a POST request to a REST API, or you may need to fetch a chunk of static content from another server.We’ll try to fetch the location of International Space Station (ISS) from the Json file in the link provided.

First we need some constants which we’ll use later in the code.

Here we are using fetch API.React Native provides the Fetch API for your networking needs. Fetch will seem familiar if you have used…


React Native combines the best parts of native development with React, a best-in-class JavaScript library for building user interfaces.

Installation Of Node or NPM

Node.js is a run-time environment which includes everything you need to execute a program written in JavaScript. It’s used for running scripts on the server to render content before it is delivered to a web browser.

NPM stands for Node Package Manager, which is an application and repository for developing and sharing JavaScript code.

To install, navigate to https://nodejs.org/en/download/ and install the node.js which also includes NPM package manager.

The EXPO

If you are new to mobile development, the easiest way to get…


Installation

Before installing, download and install Node.js. Node.js 0.10 or higher is required.

If this is a brand new project, make sure to create a package.json first with the npm init command.

Installation is done using the npm install command:

now we got node_modules and package-lock.json file.

also install body-parser and cors as a middleware

$ npm install body-parser

$ npm install cors

Express Code

Make a new Javascript file inside the main file and name it as file-name.js . And write the following code
