What version of bun is Railway using right now?

I'm having a deployment issue due to bcrypt:

Error: Cannot find module '/app/node_modules/bcrypt/lib/binding/napi-v3/bcrypt_lib.node'

The fix was released last week with v1.0.17:

You can specify it via a nixpacks.toml file in your project

for example:

[phases.setup]
  nixpkgsArchive = '9c69bc8cae2f3b38536a50801961e2e62da13595'

this is for version 1.0.18

For future readers, you can also use the latest commit like so

[phases.setup]
    nixpkgsArchive = 'master'

Where can I find the nix archives?

I need to pin to Bun 1.1.22. Bun still segfaults regularly with new releases, and I've found the best way to run it in prod is to pin to a version and manually upgrade every so often.

OK, it seems the latest Bun version is v1.1.20, but I specifically had to upgrade from that version to v1.1.22 due to segfaults, so if I try to run my Bun application on Railway, it just segfaults

Will have to Dockerize in the end, anyways

Please note we do not maintain Nix Packages, that is a separate entity that we have no affiliation with, we are simply using them as a package manager.

If you need cutting edge, for any language, on the majority of cloud container platforms, you will always need a Dockerfile.

There is no overhead to using a Dockerfile as a Dockerfile is what Nixpacks is actually generating behind the scenes for you.

@brody any chance you could work with Nix to get the latest Bun into their packages? Yes we can make our own Docker files, but

Bun docker image is built without SIMD
It's more tedious that what you get on Vercel, which seems to be able to keep up with Bun development. They have 1.1.26 at the moment.

No I'm sorry but thats not something we can do, Nix has their own maintainers for that, we are simply using them as a package manager.
