Postgres WASM

A PostgreSQL server instance running in a virtual machine running in the browser
by Supabase & Snaplet

Demo  •  Discord  •  Snaplet  •  Supabase

Since we worked on this project, awesome and more usable solutions exist:

• PGlite by ElectricSQL which is a native WASM build of Postgres
• pgmock by Stackframe which is using the same approach as this project, emulating the Postgres server in an x86 emulator

Whilepostgres-wasm was more of a proof of concept, both the above solutions can be used to run PostgreSQL in the browser or getting in-memory PostgreSQL databases!

cd packages/runtime && npx serve

Go tohttp://localhost:3000 and have fun!

This repo is split into three packages that build up the environment for running PostgreSQL in the browser.

• runtime: The v86 emulator that starts thebuildroot image
• Buildroot: Scripts to build the CPU and memory snapshot run by v86.
• Websockproxy: Networking

• v86 which isthe emulator for running x86 operating systems in the browser, without it none of the following projects would be possible
• crunchydata playground for leading the way and showing the world that it was possible to run PostgreSQL in the browser
• browser-shell which was already way ahead of its time, especially on the filesystem part
• browser-linux for showing us how we can make the pieces fit together
• Websockets Proxy the ingenious workaround that opened up the world forv86 emulators everywhere
