Hacker News readers as Progressive Web Apps

  • A spiritual successor to TodoMVC

    TodoMVC has helped thousands of developers select
    an MV* framework for their JavaScript applications.

  • However, the web ecosystem
    has evolved in the past few years allowing us to build powerful applications using
    modern browser capabilities.
  • To provide developers with examples, we collected a list of unofficial Hacker News clients built with a number of popular JavaScript frameworks and libraries.
  • Each implementation is a complete Progressive Web App that utilizes
    different progressive technologies to provide a fast, reliable and engaging experience.
  • Our implementations aim to follow a loose specification.
