I built a Chrome extension, SaveShelf for Reddit, to keep a local, searchable copy. A few notes on how it's put together.</p> <h2> Reading the list </h2> <p>With host permission for <code>www.reddit.com</code>, the service worker calls <code>/api/me.json</code> to learn the username, then pages through <code>/user/&lt;name&gt;/saved.json</code> one request at a time, backing off when Reddit rate-limits. It uses the session you're already signed into and never writes anything to Reddit.</p> <h2> Storing it </h2> <p>The library lives in IndexedDB, which needs no extra permission. Settings and sync progress go in <code>chrome.storage</code>. Optional auto-sync uses <code>chrome.alarms</code>, off by default.</p> <h2> What it can't do </h2> <p>It can only import what Reddit still lists on day one. After that it keeps each new save, even after Reddit stops listing it. It can't resurrect old ones.</p> <h2> Business model </h2> <p>Free keeps 300 items with export unlocked; Pro is $1.50 once through ExtensionPay. The source is AGPL.</p> <p>Install: <a href="https://chromewebstore.google.com/detail/hefofgeogpjlajeijffmekoplniijgjf" rel="noopener noreferrer">https://chromewebstore.google.com/detail/hefofgeogpjlajeijffmekoplniijgjf</a></p> <p>If you spot something wrong in how I'm using the extension APIs, I'd like to hear it.</p> showdev chrome javascript opensource
