# X Bookmarks → RSS
A tiny [Hono](https://hono.dev) app on Cloudflare Workers that turns your X (Twitter)
bookmarks into a live RSS 2.0 feed. Uses the official X API v2 (OAuth 2.0 user context).
State lives in a single **D1** database.
Personal/single-user: the feed is unguarded (`/feed.xml`, no key). Bookmarks are stored in
D1 and accumulate, so tweets stay in your feed even after they scroll out of X's 100-item
bookmarks API window.
## How it works
- There is **no login route**. You seed one OAuth2 refresh token into D1 once; from then on
the app refreshes the access token itself on every sync (refresh tokens rotate and the new
one is written straight back to D1).
- `GET /feed.xml` — if the last sync is older than `SYNC_TTL_SECONDS`, it refreshes the
access token, pages through your bookmarks, and upserts them into D1; then it renders RSS
from **all** stored rows (newest first). Sync failures are swallowed — the feed still
serves what's already stored.
## Setup
### 1. Create the D1 database
```sh
npm install
wrangler d1 create x-bookmarks-db # paste the printed database_id into wrangler.jsonc
npm run db:init # applies schema.sql to the remote DB
```
### 2. Set secrets (used to refresh the token)
```sh
wrangler secret put X_CLIENT_ID
wrangler secret put X_CLIENT_SECRET
```
`SYNC_TTL_SECONDS` (default 900) and `MAX_ITEMS` (default 100, items pulled per sync) are
plain vars in `wrangler.jsonc`.
### 3. Seed your refresh token
You need one OAuth2 refresh token with the `tweet.read users.read bookmark.read
offline.access` scopes (this is the only step that requires a one-time authorization — every
sync afterward is automatic). Once you have it:
```sh
export X_CLIENT_ID=... # same values as the secrets above
export X_CLIENT_SECRET=...
scripts/seed-token.sh "<your-refresh-token>"
```
The script validates the token, captures the rotated token, and writes `refresh_token` +
`user_id` into the D1 `meta` table.
### 4. Deploy & subscribe
```sh
wrangler deploy
```
Add `https://<your-worker>.workers.dev/feed.xml` to your RSS reader.
## Notes
- Refresh tokens rotate on every use and are written back to D1 immediately.
- If syncs start failing (token revoked), re-run `scripts/seed-token.sh` with a fresh token.
- The feed is unguarded by design (personal use). Don't host it where you'd mind it being
readable, or re-add a key check.
