Not agree, we should not deprecate styled-jsx.

@divlo I will happy if styled-jsx will leave long, I want to use it in my future projects, but currently it is unsafe to use it in production, because it hasn't maintaine for a long time.

styled-jsx is not deprecated, we routinely fix bugs that are opened in the Next.js repository. We don't actively watch the vercel/styled-jsx repo, though.

Please open any issues here in the Next.js tracker if you find a bug!

Thanks @Timer!
We like styled-jsx, and it's great to have this library built-in in Next.js.

I already have multiples Next.js projects deployed in production using styled-jsx and I've find no issues.
You can safely use it for your project! @artalar

I love styled-jsx but with nextjs 10.0.5 not working with @font-face using "css.global" for global css in _app.js
