pglite — Embeddable Postgres with Real-Time, Reactive Bindings
Overview
pglite is an embeddable Postgres database built in WebAssembly (WASM), allowing developers to run Postgres in environments like browsers, Node.js, Bun, and Deno without additional dependencies. It's lightweight, only 3mb gzipped, and supports many Postgres extensions, including pgvector. pglite stands out for its ability to run Postgres natively in WASM without relying on a Linux virtual machine.
Key Features
- Runs Postgres in WASM without a Linux virtual machine
- Supports many Postgres extensions, including pgvector
- Lightweight, with a 3mb gzipped size
- Real-time, reactive bindings for efficient data handling
Use Cases
- Building local-first, reactive, and real-time applications directly on Postgres
- Ephemeral in-memory database for testing and development
- Persistence to the filesystem (Node/Bun/Deno) or indexedDB (Browser)
Advantages
- No need for additional dependencies or a Linux virtual machine
- Small footprint, making it suitable for various environments
- Supports a wide range of Postgres extensions, enhancing functionality
Limitations / Considerations
- Currently in alpha status, which may imply potential instability or incomplete features
- May have limitations in terms of performance compared to a full Postgres installation
