Yes, Readability.js is injected into a hidden WKWebView for each extraction. I also recently added Defuddle as a second engine to handle JS-heavy sites and ones with custom extractors (Twitter/X, Reddit, YouTube, Hacker News, GitHub, etc.). A coordinator routes to the right engine based on the domain. After extraction, the HTML gets parsed into typed content blocks and rendered as native SwiftUI views — much nicer for theming and performance than using a web view. The Share Extension just grabs the URL and hands it off to the main app for full processing.
That's really cool that you rewrote the Postlight parser in native Swift — that's a serious undertaking. I considered going fully native for parsing but the JS engines are surprisingly capable when you let them run in a WebView. Really enjoyed reading your write-up too! The scoring approach you took for content extraction is essentially what Readability.js does under the hood too — scoring DOM nodes by heuristics and bubbling scores up to parents. Impressive that you reimplemented that in native Swift.
I built Moji because I was drowning in saved articles. Every read-it-later app I tried became a graveyard of unread links — no structure, no way to surface the right article at the right time. Moji is a native iOS read-it-later app that saves articles for offline reading and organizes them automatically using smart collections. The name "Moji" comes from 墨迹 (mòjì) in Chinese — it literally...
Yeah I’m aware of those bad user inputs, I’ll probably add some basic validation for that when I get a chance.
Given tons of posts are created everyday on Hacker News, sometimes it could be difficult to keep up with stories that I’m interested in, wouldn’t it be great to be able to collect and digest stories regularly based on my own interests? To solve this problem, I built a “smart” weekly newsletter service which delivers HN content based on topics/keywords, which I find pretty useful. What's your...
At this moment, a tag/topic is simply the keyword when you do search on HN. I agree it’s going to be more helpful to choose tags if it shows related stories.
Hacker News is a wonderful source of information which continues to inspire me to explore and learn.
