feat: add Readwise Reader (reading-state) connector - #14
Conversation
Adds a `readwise-reader` connector that carries reading *state* via the Readwise Reader API v3 — distinct from the existing highlights-only `readwise` connector (classic /api/v2, hidden). - Archive-on-finish: when a document is finished on the device, marks the matching Reader document archived + seen (PATCH /api/v3/bulk_update/). - Fan-in (pullProgress): pulls a Reader document's reading_progress so a part-read article resumes on the device, mirroring the Audiobookshelf fan-in path. Readwise exposes only a 0-1 percentage, so exact-line seek is best-effort (a prior device sample fills the position when present). - Matches by title/author metadata using the framework's decideMatch(), gated at a high confidence (0.85) so it never archives the wrong doc. - Approximates rate-limit backoff (Readwise is 20 req/min) with a cooldown, since the HttpTransport exposes no response headers. Tests: full connector unit coverage (validate/match/push/fan-in/207 retry) and updates the connector-list assertion. Full suite green (269 tests). Co-Authored-By: Claude <noreply@anthropic.com>

- Line 185: Update the document conversion logic around updatedAtMs to use the
parsed updated_at value only; return null when updated_at is absent or its
parsed timestamp is non-finite, preventing invalid InboundChange results. Add
coverage for both missing and invalid updated_at inputs.
- Line 40: Update the candidate-document pagination around MAX_CANDIDATE_PAGES
and listDocs to follow nextPageCursor until no cursor remains, while guarding
against repeated cursors to prevent an infinite loop. Ensure candidatePool
includes documents from later pages so match can select them for archiving, and
add a regression test covering a match on the second page.
- Line 49: Replace the shared rateLimitedUntil cooldown with per-token or
per-account state, and consistently key cooldown reads and updates in match,
pullProgress, and noteRateLimit by the active credential so one token’s 429 does
not suppress requests for another.

Do not create a cursor from local time.
If updated_at is absent, Date.now() creates a newer cursor on every poll. An invalid timestamp produces NaN and reaches InboundChange.updatedAtMs. Return null for both cases and add coverage for both inputs.
Proposed fix
- const updatedAtMs = doc.updated_at ? Date.parse(doc.updated_at) : Date.now();
+ const updatedAtMs = doc.updated_at ? Date.parse(doc.updated_at) : NaN;
+ if (!Number.isFinite(updatedAtMs)) return null;📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

…mestamp CodeRabbit findings on the readwise-reader connector: - Candidate pool now follows nextPageCursor to the end of each location (with a repeated-cursor loop guard) instead of reading only the first 100 docs, so a finished document on a later page still matches and archives. - Rate-limit cooldown is keyed per access token, not a module global, so one account's 429 no longer suppresses Readwise calls for other users on a multi-user server. - pullProgress always returns a finite updatedAtMs (falls back to now when updated_at is missing/unparseable) so it never leaks NaN into an InboundChange. Adds regression tests for each (second-page match, per-token isolation, missing updated_at). Full suite green (272 tests). Co-Authored-By: Claude <noreply@anthropic.com>

Is there an advantage to keeping the old api or does the new one not sync that stuff? |
Good question. Readwise's APIs are a little confusing, but as far as I can tell, the two Readwise APIs are split like this:
So there's nothing to collapse here: this PR adds reading-state sync (archive-on-finish + progress) via v3 and leaves highlights to the v2 connector. Whether the (currently hidden) v2 highlights connector is worth keeping is your call, but this PR doesn't change or replace it. |

Adds a
readwise-readerconnector that carries reading state via theReadwise Reader API v3. It's separate from the existing
readwiseconnector,which is highlights-only (classic
/api/v2) andhidden— this one carriesfinished/progress and touches the Reader API v3 only.What it does
matching Readwise Reader document archived + seen
(
PATCH /api/v3/bulk_update/→{ location: "archive", seen: true }).pullProgress). Pulls a Reader document'sreading_progressso anarticle you've part-read in Readwise resumes on the device — mirroring the
Audiobookshelf fan-in path. Readwise exposes only a 0–1 percentage, so the
exact-line seek is best-effort (a prior device position sample fills it in when
one exists; otherwise it resumes by percentage).
decideMatch(), gated at a high confidence (0.85) so it never archives thewrong document. (Sources that copy the article title verbatim into the EPUB
dc:titlematch effectively exactly.)HttpTransportexposes noresponse headers, a 429 trips a short cooldown that skips Readwise calls until
it clears (configurable via
READWISE_RATE_COOLDOWN_MS).Testing
test/readwise-reader.test.ts: validate / match / archive-on-finish /ignore-in-progress / 207 retry / fan-in (incl. cursor skip).
test/connectors.test.ts(the newconnector is listed; the classic
readwisestays hidden).Validated end-to-end against a real device (XTEINK X3 running CrossPoint
firmware): finishing an article archives it in Readwise, and a freshly
downloaded part-read article resumes near its Readwise position.
Note (not changed here)
fanOutProgressfiresfinishedatpercentage >= 0.98. Short articles one-ink often top out just under that, so archive-on-finish can miss them. Left
the threshold alone to keep this PR focused — happy to follow up with a
configurable/per-connector threshold if that's of interest.
