Description

I'm struggling to understand how to transform the vector output from Redis into a JavaScript array of numbers.

My application code is similar to the KNN search example https://github.com/redis/node-redis/blob/master/examples/search-knn.js

Here's the relevant snippet that stores vectors for similarity search:

function float32Buffer(arr) { return Buffer.from(new Float32Array(arr).buffer); } // Add some sample data... // https://redis.io/commands/hset/ await Promise.all([ client.hSet('noderedis:knn:a', { v: float32Buffer([0.1, 0.1]) }), client.hSet('noderedis:knn:b', { v: float32Buffer([0.1, 0.2]) }), client.hSet('noderedis:knn:c', { v: float32Buffer([0.1, 0.3]) }), client.hSet('noderedis:knn:d', { v: float32Buffer([0.1, 0.4]) }), ]); 

Now here is my issue: I want to get the vector by its key and be able to see the original vector as a JavaScript Array.

I tried the following:

const redisResult = await redisClient.hGet(id, 'v'); console.log(redisResult) 

The output is a cryptic string like "�����'<�n;�h�?�Vٍ���/<7c��" that I believe may be [RESP](https://redis.io/docs/reference/protocol-spec/) format. I want to transform that result into its corresponding array, e.g. [0.1, 0.3]`, however I'm not sure how to do so. Any guidance would be greatly appreciated. Thanks!

I wonder if I should try using https://www.npmjs.com/package/redis-parser ...
