Build React Native App (4) - Redux, Jest, and NativeBase

From this blog, typescript feature will be added. There are couple of ways to implement static type checking like; flow from facebook, PropTypes and Typescript.Typescript is well integrated with Visual Studio Code and supports better linter, error messages, and intellisense.Reference siteGithub Sample Ex4Currnet versionD:\GitRepo\reactnative>npm --version 6.3.0 D:\GitRepo\reactnative>react-native --version react-native-cli: 2.0.1 react-native: n/a - not inside a React Native project directory D:\GitRepo\reactnative>yarn --version 1.9.4 Creating React Native App$ react-native init ex4 If you want to specify the version, add "--version 0.57.3" at the end.Add NativeBase to React Native$ npm install native-base --save ... + native-base@2.8.1 added 71 packages from 42 contributors, removed 50 packages, updated 829 packages and audited 34989 packages in 138.542s found 0 vulnerabilities $ $ yarn yarn install v1.9.4 warning package-lock.json found.

Developing SPA app with AngularJS, Spring, Spring Boot, REST, and MyBatis - 2. Unit Testing

Developing SPA app with AngularJS, Spring, SpringBoot, REST, and MyBatis - 2. Unit Testing Introduction From the first posting, we just created simple application and run the application using maven and SpringBoot. From this tutorial, we will try to figure out how to do the unit testing with SpringBoot

Developing app with AngularJS, Spring, Spring Boot, REST, and MyBatis

Developing SPA app with Atom, AngularJS, Spring, SpringBoot, REST, and MyBatis - 1. Setup Environment Introduction I believe the SPA(Single Page Application) will be the direction of future software development and this will be my first small project to develop SPA using following major components; AngularJS for the front-end, Spring REST for the back-end, Spring Boot for running environment, and MyBatis for the database persistence layer. I am a big fan of MyBatis because of flexibility, performance, and easy way to implement MVVM framework.
One of main reason to develop this sample is to understand the structure of AngularJS and Spring framework. If you develop applications with STS or Eclipse, these IDEs will do everything for you, but sometimes it is hard to understand what happening behind scene.
If you are not familiar with Spring Boot project, I strongly recommend to read Official SpringBoot Start Document
