fix(moss-md-indexer): migrate off legacy @inferedge-rest/moss SDK - #528
PredictiveManish wants to merge 15 commits into
Conversation
Replace the deprecated @inferedge-rest/moss dependency with @moss-dev/moss and switch from destructive delete-then-create to non-destructive upsert. The old upload flow deleted the live index before rebuilding it, which meant search was broken during the upload window and completely gone if the upload failed. The new flow upserts new documents and removes stale ones, keeping the index available throughout. - Replace MossRestClient with MossClient from @moss-dev/moss - Add non-destructive upsert as default behavior - Add recreate option for legacy delete-then-create when needed - Add unit tests for uploader with mocked MossClient - Update vitepress-plugin-moss references to new package name

In `@packages/moss-md-indexer/CHANGELOG.md`:
- Line 14: Update the upload-failure guarantee in the changelog to state only
that a failed upload does not delete the existing index; remove the claim that
the existing index remains intact or that no data is lost.
In `@packages/moss-md-indexer/src/uploader.ts`:
- Around line 68-70: Update the getIndex error handling in the uploader flow to
treat only the documented “Index not found” error as a missing index and proceed
to createIndex; rethrow every other error, including authentication failures, so
the original getIndex failure propagates.
- Line 85: Update uploadDocuments in the existing-index path to capture the
result of mossClient.addDocs, perform stale-document deletion as currently
implemented, then return that result. Add a test covering this path and
verifying the MutationResult, including fields such as jobId, is returned.

Included review availability: Your plan provides up to 4 included reviews per hour; 3 remain after this review.
- Add MossClient.close() in finally blocks to release native resources - Check model mismatch on getIndex and warn user to recreate - Handle empty docs on existing index (delete all stale docs) - Add engines field (node >=20.4) matching SDK requirement - Wrap createIndex in try/catch in default path for consistent error msg - Add tests for close(), model mismatch, empty docs on existing index
The getIndex existence check is intentionally outside the upload error wrapper so auth/network errors propagate with their original type and are not wrapped in 'Moss Upload Failed'. Added comment to make this explicit for code reviewers.
If the markdown parser fails or returns nothing, we should not wipe the existing index. Empty document sets now leave the index untouched with a warning. Users who actually want to clear an index should use the recreate option.
The empty documents check now runs at the top of uploadDocuments, before any delete or create calls. This prevents both the recreate path and the default path from touching the live index when the document set is empty (e.g. parser failure).

Legacy indexes (no version/artifact) and model-mismatched indexes now throw with instructions to use recreate: true instead of warning and continuing with addDocs, which would leave search broken.
IndexInfo has two version fields: index.version (build format) and model.version (artifact identity). Legacy detection needs the model artifact version, not the index format version.
Legacy indexes (built by old SDK without model artifact version) are useless with the new SDK since text queries won't work. Instead of throwing and telling users to pass recreate:true (which the plugin doesn't expose), auto-recreate them on first upload. Model mismatches still throw since that's a user config error.

Legacy indexes still throw with a clear error message, but now the
vitepress plugin reads recreate from search config options and passes
it to uploadDocuments. Users can set recreate: true in their VitePress
config to handle the one-time migration from the old SDK.
search: {
provider: 'moss',
options: { projectId, projectKey, indexName, recreate: true }
}
uploadDocuments now receives a third argument (UploadOptions).
Update the plugin test to expect { recreate: false } by default.

sync() now accepts recreate and forwards it to uploadDocuments, so callers using the documented sync() API can handle legacy indexes without needing to call uploadDocuments directly.

Description
This PR fixes two problems in
packages/moss-md-indexer:Problem 1: Legacy SDK dependency
The md-indexer depends on
@inferedge-rest/moss(last published as 1.0.0-beta.3), a pre-release SDK that the rest of the repo has moved away from. Every other JS package uses@moss-dev/moss. The old package name also appears invitepress-plugin-mosscomments and README. The version range>=1.0.0-beta.3is unbounded, meaning a future major release under that scope would install without anyone noticing.Problem 2: Destructive upload behavior
Every time a VitePress build runs, the plugin calls
uploadDocuments()which deletes the live index and then recreates it. UntilcreateIndexfinishes, search on the deployed site has no index to query. IfcreateIndexfails (network error, quota, bad document), the site is left with no index at all. ThedeleteIndexcall also swallows most errors and only logs a warning.What changed
