Hypvector
platypii · App
HypVector is a JavaScript library for storing and querying embedding vectors directly in Apache Parquet files. A file on S3 or local disk becomes the vector store, and it describes itself, holding the dimension, metric, normalisation and cluster centroids in its metadata. You can run exact search, or approximate search that combines binary codes, clusters and reranking. It works in browsers and Node, includes TypeScript definitions and is part of HypStack, an open-source stack for AI observability.

Why it's useful
A single Parquet file on S3 or local disk can serve as your vector store, so similarity search does not need a separate database server.
What you could do with it
- Write your embeddings and their ids to a Parquet file, then search it for the vectors closest to a query embedding.
- Search a Parquet vector file hosted at a URL straight from the browser, with no server in between.
- Choose exact search over the full vector column, or approximate search using binary codes, clusters and reranking.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.2.2, the file with digest sha512-hKuxBHES27VUZP2O/fo2sd6tSAJMpzCcPn9ykIcVP8w9WmxC/4rWwctDlfScTnru3bz6sPJ49sIFNx5TGytenw==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y hypvector@0.2.2Pinned to 0.2.2, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.
The badge, if this is your listing
It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
