[epos] Web Extension Engine
A browser extension for building browser extensions
What it does
Epos is an opinionated engine for building Chromium browser extensions with React. While frameworks like WXT and Plasmo prioritize flexibility, Epos focuses on a zero-config experience with powerful features that work out of the box. At a high level, Epos gives you: - A cross-context messaging system - Shared state with persistence and sync - Storage for files and data - Extension APIs available in any context - Automatic script injection + Shadow DOM - A simpler setup through epos.json

By using Extension.js, adding the package to your npm scripts is all it…

Hey HN, we're excited to have people try out our framework! When we built out a Chrome extension earlier this year, we noticed that the config was too imperative. You had to constantly tell Chrome via the manifest.json file where your files were, what your permissions should be, etc. So we thought it might be interesting to build a more declarative framework. When we built a proof of concept, we enjoyed working with it and decided to invest more time into making it usable and adding more features. We're still pretty early in building it out, and there's a bunch more we want to add, but this…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
