Project mention: Show HN: I open-sourced the in-memory PostgreSQL I built at work for E2E tests | news.ycombinator.com | 2024-04-07Hey HN! For a few months, I've been building pgmock at work for our E2E and unit test suite. It emulates Postgres in WebAssembly and has full feature parity with production databases.
The cool thing about it is that you don't need any external processes or proxies. If your platform can run WASM (Node.js, browser, etc.), it can probably run pgmock. Creating a new database with mock data is as simple as creating a JavaScript object.
It's a bit different from the amazing pglite [1] (which inspired me to open-source pgmock in the first place). While pgmock runs an x86 emulator, pglite compiles a Postgres fork to native WASM directly and is hence much faster and more lightweight. However, it only supports single-user mode and a select few extensions, so you can't connect to it with normal Postgres clients (which is quite crucial for E2E testing).
Theoretically, it could be modified to run any Docker image on WebAssembly platforms. Anything specific you'd like to see?
Happy hacking!

Based on your comment below I think you figured out the difference - but if you're looking to execute JS, you can pick between ShadowRealm (where available, or using a polyfill) or my library quickjs-emscripten.
Pros of quickjs-emscripten over ShadowRealm:
- You can use quickjs today in any browser with WASM. ShadowRealm isn't available yet, and polyfills have had security issues in the past. See https://www.figma.com/blog/an-update-on-plugin-security/
- In ShadowRealm eval, untrusted code can consume arbitrary CPU cycles. With QuickJS, you can control the CPU time used during an `eval` using an [interrupt handler] that's called periodically during the eval.
- In ShadowRealm eval, untrusted code can allocate arbitrary amounts of memory. With QuickJS, you can control both the [stack size] and the [heap size] available inside the runtime.
- quickjs-emscripten can do interesting things with custom module loaders and facades that allow synchronous code inside the runtime to call async code on the host.
Pros of ShadowRealm over QuickJS:
- ShadowRealm will (presumably?) execute code using your native runtime, probably v8, JavaScriptCore, or SpiderMonkey. Quickjs is orders of magnitude slower than JIT'd javascript performance of v8 etc. It's also slower than v8/JSC's interpreters, although not by a huge amount. See [benchmarks] from 2019.
- You can easily call and pass values to ShadowRealm imported functions. Talking to quickjs-emscripten guest code requires a lot of fiddly and manual object building.
- Overall the quickjs(-emscripten) API is verbose, and requires manual memory management of references to values inside the quickjs runtime.

A little context: this dive into Fortran is part of the excellent work George has been doing on WebR, to get R running in the browser. The R sources contain a fair bit of Fortran code, and I believe WebR originally used f2c to compile the Fortran to C first, before compiling that to wasm.
With the patches to LLVM Flang, WebR can be built with a real Fortran compiler.
I think George didn't want to say it directly in the blog post, but he has said that he's hoping that Flang would take his patches or implement better ones. That would be a win-win -- these patches wouldn't need to be maintained separately, and since unmodified Flang would be able to compile to wasm, it would benefit other projects out there that use Fortran.
