NUS Library Proxy Helper

A small Chrome Manifest V3 extension that turns the NUS Libraries proxy bookmarklet into a click-to-proxy and auto-proxy workflow for publication pages.

The NUS guide documents the same core redirect pattern:

javascript:void(location.href='https://libproxy1.nus.edu.sg/login?url='+location.href);

This extension uses the equivalent URL:

https://libproxy1.nus.edu.sg/login?url=<current URL>

Install locally

1. Open chrome://extensions.
2. Enable Developer mode.
3. Click Load unpacked.
4. Select this folder: /Users/liyutong/Downloads/nus-temper-monkey.

Use

• Click the extension icon, then choose Open through NUS proxy.
• On configured publication article pages, the content script can auto-redirect through the proxy.
• The popup explores the current page for DOI, PDF, citation, supplement, and full-text links. Use Proxy beside a detected resource to open that resource through NUS.
• Use the popup Access Guide download button to save a local Markdown guide.
• If NUS Libraries does not subscribe to a title or has not configured a vendor for proxy access, the redirected page may still fail.

Expand publisher support

Open the extension options page and add a publication site:

• Name: human-readable publisher name.
• Domains: one per line, such as dl.acm.org or *.publisher.com.
• URL path patterns: one per line, such as /doi/, /article/, or /science/article/.
• Auto-proxy: controls whether matched pages redirect automatically.

The default site list lives in src/config.js. The options page stores edits in Chrome sync storage and supports JSON export/import for moving rules across browsers.

Privacy

The extension does not send data to a custom server. It reads the active page to detect common scholarly resources and redirects selected pages or links to the NUS Libraries proxy.
