Frameworks and Tools for Progressive Web Apps

Videocap from GDD Europe '17 with tips and tools from proper PWA development
15 September   506

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.

Progressive Web Apps are spreading across the web faster than anyone could have predicted. Two years ago, developers needed to do most of the plumbing themselves to take advantage of the new APIs available in the browser, but today we have powerful and robust tools that can help developers of any background to quickly ship more engaging applications. In this video, you learn about: best practices for PWAs that you should be taking advantage of, the tools that exist to assist developers coming from a wide variety of backgrounds, the philosophies and visions behind these tools, and practical tips for getting started.

What is Truffle?

Small introduction to the most popular Ethereum development framework
11 December   730

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.
