Plugins: Replace plugin: Unexpected token when using "process" plain text in Svelte

[MichielLeyman]

• Rollup Plugin Name: replace
• Rollup Plugin Version: 2.3.1
• Rollup Version: 1.20.0
• Operating System (or Browser): Fedora 31
• Node Version: 10.16.3

How Do We Reproduce?

https://repl.it/repls/ScarceOverjoyedRoute

Expected Behavior

Using the plaintext "process" should not stop the application from compiling. Every time I use "process" in the HTML section of a .svelte file, things break.
Finding the source of this issue took quite a while, I haven't found any other keywords that break compilation.

Actual Behavior

Error: Unexpected token (Note that you need plugins to import files that are not JavaScript)

Thanks for reporting. Do you have a stack trace handy you could add to the issue? (I'm away from my machine right now, but was curious)

@shellscape Please reopen the issue. I've just stumbled upon this and it took me a while to find out what was breaking the compilation. The error output is similar to that posted by @MichielLeyman.

We don't reopen stale issues unless someone is willing to take it on.

[ganigeorgiev]

@shellscape I'm not familiar with the rollup codebase (first project with it). Could you at least point me where to look?

[MichielLeyman]

@ganigeorgiev If I recall correctly, this happened because I used the replace plugin a certain way to pass environment variables. I ended up making variables globally available instead, as a workaround in that project:

replace({
  NODE_ENV: JSON.stringify(process.env.NODE_ENV),
})

@MichielLeyman Ah, thank you.
