A PostgreSQL server instance running in a virtual machine running in the browser

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
While postgres-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 to http://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 the
buildroot
image - Buildroot: Scripts to build the CPU and memory snapshot run by v86.
- Websockproxy: Networking
- v86 which is the 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 for v86 emulators everywhere
