PGlite Embeddable WASM Postgres for Browser and Node.js

PGlite is a WASM build of Postgres packaged as a TypeScript library that runs a full Postgres database in the browser, Node.js, Bun, and Deno. At only 3.7MB gzipped, it enables local-first applications with real SQL capabilities and no external database dependencies.

Installation

Use the upstream install or setup path that matches your environment:

• npm install @electric-sql/pglite
• Docker is required to build the WASM module, along with Node (v20 or above) and pnpm for package management and building the TypeScript packages.
• git clone --recurse-submodules https://github.com/electric-sql/pglite
• pnpm install

Requirements and caveats from upstream:
