created regex to ignore .goutputstream files

I created a watcher with chokidar which worked properly but then now I want to ignore some files with regex but doesn't seem to be working though.

What have I done wrong with this code or regex?

here is my code

const watcher = chokidar.watch(process.env.WATCH_PATH, {

    // ignored: /(^|[/\])../,

    ignored: [/^.goutputstream/],

    persistent: true

});

EDIT:
My bad, I wanted anything that starts with .goutputstream so could be .goutputstream-blahblahblah

Do you mean to match any string ending with .goutputstream? Try /.goutputstream$/

Please (re)read Anders Kaseorg's response, and upvote and "Accept" it if it works. As he points out, you have (at least) two issues: 1) you need to escape the period - ., 2) If .goutputstream is REALLY the beginning of the text, you can use /^.goutputstream. Otherwise, if there's a leading path, you can't.

Two problems:

. matches any character, you need to write . to match (only) a period.

^ only matches at the beginning of the string, but you’re probably getting some/path/.goutputstream which doesn’t match your pattern at the beginning of the string. (That’s why the commented regex began (^|[/\]), which matches either the beginning of the string, or a slash or backslash character.)

what you meant is doing something like /(^|[/\]).goutputstream./ ? I always split and pop so I get the filename which would make . the beginning but doesn't really matter. The commented regex is the original sample but I do not want to ignore all . file/folder though so that's why I want to specify which to ignore.

Well, did you try it? Note again that . matches any character, so by putting . at the end of your regex this time, you’ve told chokidar to only ignore filenames with a character after .goutputstream (i.e. .goutputstream is not at the end); is that what you meant? Also, it doesn’t matter what you do to the filename after getting it back from chokidar, with split and pop or anything else (by the way, there’s path.basename for that), because the regex test already happened.

sryz I am really really bad with regex. Yes I have tried after I replied you but doesn't seem to help much. To make it simple as long as the string contains .goutputstream I want to ignore so if it's .goutputstream-fiDMeifnd, hello/.goutputstream-blah, .goutputstream_anything
