Describe the bug

I don't know what has changed. My plugin worked well. I created backups of my development.

Now any plugin I compiled breaks next js.
If I compile my old backup it breaks next js.
I create an empty plugin according to the instructions "getting-started" - it breaks next js.
https://swc.rs/docs/plugin/ecmascript/getting-started

Any plugin that I compile on my computer breaks next js. The plugins that I compiled the day before yesterday work well.

I completely reinstalled Cargo and Rust. Reinstalled swc_cli and swc_core. It did not help.
I have tried many different versions of rust. (nightly and stable). It did not help.

I really need help.
I am ready to provide any information and try any guesses.

This error is printed to the console many times

Input code

swc plugin new --target-type wasm32-wasi my-first-plugin

Config

Expected behavior

Next js doesn't break.

Actual behavior

There are no errors during compilation. But any plugin I compile breaks Next js. The plugins I compiled earlier do not break Next js.

Version

swc_cli: latest, swc_core: latest, cargo: latest, rust:latest

Additional context

I don't have any other dependencies. I removed everything and installed only the latest swc.

The problem was that I had dependencies in my Cargo.toml that also added WASM import/exports without being used for the functionality on the interface to SWC. Removing the dependency solved to problem.

I have a similar problem with my WebAssembly plugin. I get:

Error: failed to handle: failed to invoke plugin: failed to invoke plugin on 'Some("test.js")'

Caused by:
    Error while importing "__wbindgen_placeholder__"."__wbindgen_jsval_loose_eq": unknown import. Expected Function(FunctionType { params: [I32, I32], results: [I32] })

    at Compiler.transformSync (.../node_modules/@swc/core/index.js:241:29)
    at Object.transformSync (.../node_modules/@swc/core/index.js:348:21)

I already spent (too) many hours on this. I am using the Rust Toolchain nightly-2022-09-23 and the very latest versions of SWC.

I observed that plugins that work well (for example, the Istanbul Coverage Plugin) have a considerably smaller wasm interface when inspecting it with wasmer inspect. For example:

while my plugin has all the bindgen exports (and imports). I have not yet understood why this is the case.

I have a similar problem but only 2 dependencies. swc_core and serde. Please take a look at this repository. Do you see what I can change? https://github.com/HeartyPorridge/my-first-plugin

stahlbauer May 17, 2023

Another important point was to really be in line with the version of SWC.

Would adding serde-wasm-bindgen = { version = "0.5.0" } change something in your case? (Just a guess.)

It did not help.
I have tried many versions, tried on virtual machines (ubuntu and windows).
SWC "getting-started" https://swc.rs/docs/plugin/ecmascript/getting-started doesn't work :(

romanusname May 17, 2023

Please write the versions with which you have no problems. I'm interested in rust nightly, swc_core, swc_cli

Please tell me which version you are using. I have this problem for many days now
