v0.14.0

What's New

Breaking Changes

• fetch() replaces axios — All HTTP requests now use the built-in fetch() API. Projects relying on axios interceptors or custom axios config need to switch to the requestConfig option (a standard RequestInit object) on OpenAIEmbeddings.
• Node.js 22.x minimum — Minimum Node.js version is now 22.x (up from 20.x), driven by undici@8.0.0 requiring node >=22.19.0.

New Features

• Browser & Electron support — Full browser and Electron compatibility with dedicated vectra/browser entry point, IndexedDBStorage, and Webpack browser bundle (#99)
• Local embeddings — TransformersEmbeddings class using @huggingface/transformers for fully local embedding generation with GPU/WASM device selection, quantization, and progress callbacks
• Protocol Buffer format — Opt-in binary protobuf-based index serialization achieving 40–50% smaller index files via ProtobufCodec
• gRPC server — vectra serve exposes 19 RPCs for cross-language access
• Language binding generator — vectra generate scaffolds clients for Python, C#, Rust, Go, Java, TypeScript
• FolderWatcher — vectra watch CLI command and FolderWatcher class for automatic re-indexing when files change
• Pluggable storage systems — Storage abstraction layer allowing custom storage backends (in-memory, cloud, database)
• vectra delete — Delete indexes from the CLI
• vectra migrate — Migrate between JSON and protobuf formats
• BrowserWebFetcher — Browser-native web fetcher using Fetch API + DOMParser
• TransformersTokenizer — Tokenizer matching TransformersEmbeddings model for chunk alignment
• Agent Ready support — Agent-compatible capabilities

Security

• Removed axios dependency — Eliminated supply chain risk by switching to built-in fetch()
• Fixed dependency vulnerabilities — Resolved additional security issues in transitive dependencies

Infrastructure

• CI/CD pipeline with GitHub Actions (build, test, lint, coverage via Coveralls)
• ESLint configuration added
• Developer documentation site launched
• GitHub Pages docs site with Jekyll + just-the-docs
