Styling a component with forwardRef

[molily]

Environment

• Linaria version: @linaria/core 6.2.0, @linaria/react 6.2.1
• Next.js 14.2.5, next-with-linaria 0.7.0
• Node.js version: 20.16.0
• OS: macOS 14.5

Description

Hi, I'm using Linaria in a Next project via next-with-linaria.

In a file marked with 'use client', I have a component defined with forwardRef that accepts styles:

const StylableInputFwdRef = forwardRef<HTMLInputElement, StylableInputProps>(({ label, className, style }, ref) =>
  <p>
    <label>
      {label}{" "}
      <input ref={ref} className={ className } style={ style } />
    </label>
  </p>
);

I would like to style this component with Linaria:

const InputLinariaFwdRef = styled(StylableInputFwdRef)`
  border: 2px inset blue;
`;

This declaration raises an error:

next14-linaria/node_modules/@wyw-in-js/transform/lib/module.js:224
      throw new EvalError(`${e.message} in${this.callstack.join('\n| ')}\n`);
      ^

EvalError: TextEncoder is not defined in next14-linaria/node_modules/next/dist/compiled/next-server/app-page.runtime.dev.js
| next14-linaria/node_modules/next/dist/server/future/route-modules/app-page/module.compiled.js
| next14-linaria/node_modules/next/dist/server/future/route-modules/app-page/vendored/rsc/react.js
| next14-linaria/src/app/ClientComponent.tsx
    at evalFile.next (<anonymous>)

The error seems to happen in Next.js code but is re-thrown by wyw-in-js.

I'm not sure whether my problem is caused by Linaria itself, by next-with-linaria, wyw-in-js or Next.js. I'd appreciate any hints.

Is is possible to wrap a component with forwardRef? Am I fundamentally misunderstanding how Linaria works in a client component?

Thanks for your time and thank you for this project!

Reproducible Demo

Fresh Next.js project with Linaria: https://github.com/molily/next14-linaria
Relevant code is in https://github.com/molily/next14-linaria/blob/main/src/app/ClientComponent.tsx

• npm install
• npm run dev
• Go to http://localhost:3000

Hi,

the issue seems to be a typing issue of forwardRef. Assigning the return-type of forwardRef to StylableInputFwdRef works:

- const StylableInputFwdRef = forwardRef<HTMLInputElement, StylableInputProps>(({ label, className, style }, ref) =>
+ const StylableInputFwdRef: React.ForwardRefExoticComponent<React.PropsWithoutRef<StylableInputProps> & React.RefAttributes<HTMLInputElement>> = forwardRef(({ label, className, style }, ref) =>

Note that linaria's styled already calls forwardRef on every component regardless whether it's necessary or not.
