Progressive Web Apps with Angular

Learn how Angular.js works with Progressive Web Apps out of the box
09 August

Hype.Codes continues to introduce the PWA to our readers.

Progressive Web Apps (PWA) was announced by Google in 2015. This format of creating mobile websites attracted attention due to the relative ease of development and almost instantaneous interaction with the user. As early as May 2016, at the Google I / O Developer Conference, The Washington Post demonstrated its mobile hybrid site-application.

What is PWA? You can perceive this as a site built using web technologies, but which interacts with the user as an application. The advances in the development of browsers, cache and Push-interfaces allowed installing the application on the home screen directly from the browser, receiving pop-up notifications and even working offline.

In this video, you will learn about the PWA features of Angular.

AngularJS is a JavaScript-based open-source front-end web application framework mainly maintained by Google and by a community of individuals and corporations to address many of the challenges encountered in developing single-page applications. The JavaScript components complement Apache Cordova, the framework used for developing cross-platform mobile apps. It aims to simplify both the development and the testing of such applications by providing a framework for client-side model–view–controller (MVC) and model–view–viewmodel (MVVM) architectures, along with components commonly used in rich Internet applications.

Angular is a platform for building apps with the web, and supports Progressive Web Apps out of the box. Learn how Angular's tools enable you to increase engagement with faster loads, offline access, and push notifications through progressive enhancement of your mobile web apps.

What is Truffle?

Small introduction to the most popular Ethereum development framework
11 December

Truffle is a development environment, testing framework and asset pipeline for Ethereum, aiming to make life as an Ethereum developer easier. 

According to the developers, these are main features: 

  • BUILT-IN SMART CONTRACT COMPILATION, LINKING, DEPLOYMENT AND BINARY MANAGEMENT
    • Truffle takes care of managing your contract artifacts so you don’t have to. Includes support for custom deployments, library linking and complex Ethereum applications.
  • AUTOMATED CONTRACT TESTING FOR RAPID DEVELOPMENT
    • Bring your dapp development to the 21st century. Write automated tests for your contracts in both JavaScript and Solidity, and get your contracts developed quickly.
  • SCRIPTABLE DEPLOYMENT & MIGRATIONS FRAMEWORK
    • Write simple, manageable deployment scripts that acknowledge your application will change over time. Foster your dapp’s evolution and ensure you can maintain your contracts far into the future.
  • NETWORK MANAGEMENT FOR DEPLOYING TO BOTH PUBLIC & PRIVATE NETWORKS
    • Don’t manage network artifacts ever again. Let Truffle do it for you, and put your focus on dapp development where it belongs.
  • ACCESS TO HUNDREDS OF EXTERNAL PACKAGES
    • Pull in hundreds of smart contract dependencies from NPM and EthPM to have your code stand on the shoulders of giants.
  • INTERACTIVE CONSOLE FOR DIRECT CONTRACT COMMUNICATION
    • Use Truffle to save time and talk to your contracts via an interactive console, which includes access to all your built contracts and all available Truffle commands.
  • EXTERNAL SCRIPT RUNNER THAT EXECUTES SCRIPTS WITHIN A TRUFFLE ENVIRONMENT
    • Use Truffle to bootstrap your contracts and run a network-aware script, without hassle.
  • BUILT FOR SPEED
    • Whether you’re compiling contracts or running unit tests, Truffle includes clever optimizations to ensure you only compile what you have to and your tests run as quickly as possible. When used along with Ganache, you can develop your dapps quickly and get real code deployed, fast.
