Open Source — vectools & n8n Workflows

Open Source · npm Package · n8n Official Gallery

Two threads of open-source work: a small utility library for the AI embeddings ecosystem, and automation templates published in n8n’s official workflow gallery.

vectools (npm)

vectools is a zero-dependency, ESM-native utility library for vector mathematics, built for the growing ecosystem of AI embedding workflows in JavaScript and TypeScript. Working on semantic search, RAG pipelines, and embedding-based retrieval, the same low-level operations — cosine similarity, dot products, normalization — kept coming up without a lightweight, dependency-free option in the JS ecosystem.

import { cosineSimilarity } from 'vectools';

const score = cosineSimilarity([1, 2, 3], [1, 2, 4]);
// → 0.9914601339836674

• Zero dependencies — no transitive supply-chain risk
• Pure ESM — tree-shakeable, works natively in Node.js 12+, Deno, and browsers
• TypeScript-first — ships with full .d.ts type definitions

npm install vectools

n8n Workflows

Three workflow templates published under my n8n creator profile, covering AI-assisted document parsing and job search automation with Google Gemini:

• Extract Job Titles from Resumes with Google Gemini AI — parses unstructured resume documents and extracts job titles with semantic accuracy, handling nested or inconsistent formats.
• Score and Log Relevant Job Listings using Google Gemini, JSearch and Notion — cross-references live JSearch listings against a candidate profile, scores relevance with Gemini, and logs matches to Notion.
• A third workflow runs locally as part of the same automation stack, not yet published to the gallery.
