Check if we support Bun

[unflxw]

Bun is a new JavaScript run-time written in Zig. It's designed to be Node-compatible, including NAPI -- so we probably support it.

Timebox: 0.5 days

To do

• See if we already support Bun
  • If we support it
    • Document it
    • Create an issue to add it to the build matrix
  • If we don't support it: [Timebox: ?]
    • Try to understand why and document it here
    • Fix it if possible

Promising, but not there yet.

The AppSignal installer works fine (although it is hardcoded to run npm install — this will fail for users who have Bun and not Node)

They do want to eventually support all of Node, including NAPI, but for now initialising the AppSignal client fails with a SIGSEGV from the extension. I didn't look any deeper into why.

They also don’t yet support the necessary hooks on the JS side for require-in-the-middle to work (which is what OpenTelemetry instrumentations use internally to intercept imports) so even if the extension and agent initialised correctly, nothing would be instrumented.

Bump, would this be explored in future?

[unflxw]

Hi @afxal! We'd like to support this in the future, though we can't commit to a specific timeframe.

It seems that Bun recently added support for require-in-the-middle, so that's one of the pieces of the puzzle we need. It might be time to give this another try.

@unflxw appreciate the fast response, i'll keep an eye on this issue. 🫡
