I've been interested in two interlinked technologies for some time. The first is Progressive Web Apps (https://web.dev/progressive-web-apps) which lets the websites behave more like native apps, and the second is the File System API (https://developer.mozilla.org/en-US/docs/Web/API/File_System_Access_API) which enables browsers to access the local file system.<p>I decided to go a little more deeply into them, and tonight, I uploaded a repository (https://github.com/joaomelo/textorama) with an open-source project I've been working on nights and weekends for the last few weeks.<p>Textorama is a web editor that works with plain text files in your local system. The content is in your disk in a universal open format, and the browser ensures the editor only accesses the files you permit.<p>There is a working instance available here: https://textorama.online.
