# Read a Hacker News thread with the full comment tree

## What works

1. Take the item id from the thread URL (the id= parameter).
2. Fetch the item from the Algolia HN API at hn.algolia.com/api/v1/items/<id>. It returns the story and the whole nested comment tree in one response.
3. Comment text is HTML; strip tags or convert to text before summarising.

## Pitfalls

- The official Firebase API (hacker-news.firebaseio.com) returns one item per request, so a big thread takes hundreds of calls.
- Deleted and dead comments come back with empty text.
