8. 8AV
   A Visual IDE for React▲479

   I made this because building UIs in a lexical medium like code is super annoying. I have to pre-render what I’m making in my head, and then jump between the browser and IDE to test. I was inspired by the developer console in chrome and safari since I end up editing css there because it’s ironically more convenient. Hope it’s useful!

    LiveViewJS – TypeScript back end for LiveView Apps (Phoenix LiveView)▲146

    Author here. I really love the programming paradigm behind by Phoenix LiveView applications and wanted to expand the ecosystem to include programmers like myself that love Typescript. In summary, LiveViewJS reuses all the Phoenix client code and implemented a new backend in Typescript to handle client events and send back updates. Lots more detail and examples in the repo. Would love any questions and/or feedback. Thanks!
