News Translation Analysis

Current Architecture

The application fetches news via src/services/rss.ts.

• Mechanism: Direct HTTP requests (via proxy) to RSS/Atom XML feeds.
• Processing: DOMParser parses XML client-side.
• Storage: Items are stored in-memory in App.ts (allNews, newsByCategory).

The Challenge

Legacy RSS feeds are static XML files in their original language. There is no built-in "negotiation" for language. To display French news, we must either:

1. Fetch French feeds.
2. Translate English feeds on the fly.

Proposed Solutions

Option 1: Localized Feed Discovery (Recommended for "Major" Support)

Instead of forcing translation, we switch the source based on the selected language.

• Implementation:
  • In src/config/feeds.ts, change the simple URL string to an object: url: { en: '...', fr: '...' } or separate constant lists FEEDS_EN, FEEDS_FR.
  • Pros: Zero latency, native content quality, no API costs.
  • Cons: Hard to find equivalent feeds for niche topics (e.g., specific mil-tech blogs) in all languages.
  • Strategy: Creating a curated list of international feeds for major categories (World, Politics, Finance) is the most robust & scalable approach.

Option 2: On-Demand Client-Side Translation

Add a "Translate" button to each news card.

• Implementation:
  • Click triggers a call to a translation API (Google/DeepL/LLM).
  • Store result in a local cache (Map).
• Pros: Low cost (only used when needed), preserves original context.
• Cons: User friction (click to read).

Option 3: Automatic Auto-Translation (Not Recommended)

Translating 500+ headlines on every load.

• Cons:
  • Cost: Prohibitive for free/low-cost APIs.
  • Latency: Massive slowdown on startup.
  • Quality: Short headlines often translate poorly without context.

Recommendation

Hybrid Approach:

1. Primary: Source localized feeds where possible (e.g., Le Monde for FR, Spiegel for DE). This requires a community effort to curate feeds.json for each locale.
2. Fallback: Keep English feeds for niche tech/intel sources where no alternative exists.
3. Feature: Add a "Summarize & Translate" button using the existing LLM worker. The prompt to the LLM (currently used for summaries) can be adjusted to "Summarize this in [Current Language]".

Next Steps

1. Audit src/config/feeds.ts to structure it for multi-language support.
2. Update rss.ts to select the correct URL based on i18n.language.
