Nextjs 13.4.8 + swc-plugin = build fail

[aleksanderd]

Hi!

Just updated to latest nextjs (need some features) and got build failed

...

checked several nextjs versions and noticed the problem appeared at 13.4.8

Got similar problem
Looks like its not only Next related

"@effector/swc-plugin": "^0.0.10",  

 "@swc/cli": "^0.1.62",
"@swc/core": "^1.3.68",

Still an issue, but it does not look related specifically to Next. I stumbled across it using Vite setup.

Here's a minimal reproduction:

.swcrc

{
  "$schema": "https://json.schemastore.org/swcrc",
  "jsc": {
    "target": "esnext",
    "experimental": {
      "plugins": [["@effector/swc-plugin", {}]]
    }
  }
}

in.js

"asd"?.toString;

out.js

this?.?;

$ RUST_BACKTRACE=full yarn swc in.js -o out.js

---

In this instance, it does not crash. Here's a version that does:

in.js + stacktrace

in.js

'asd'?.toString()
setTimeout(() => 'asd'?.connect(), 0)

stacktrace:

I'm not deeply familiar with Rust, but I can try and make a PR if someone can point me in the correct direction.

This plugin a bit obsolete and unsupported for a while,
you can try new effector SWC plugin from community:
https://github.com/kireevmp/effector-swc-plugin
(but read documentation carefully, especially about version choosing)

[yumauri]

Ahaha, @kireevmp I didn't pay attention, that the last message was from the author of new plugin 😅
