  • This is a bugfix
  • This is a feature
  • This is a code refactor
  • This is a test update
  • This is a docs update
  • This is a metadata update

For Bugs and Features; did you add new tests?

I'm not sure how exactly to write a test for this except testing it manually.

Motivation / Use-Case

fixes #1781

Breaking Changes

No

Additional Info

I had a very strange behavior when I try to change the value of this.watchOptions when I do

this.watchOptions = options.watchOptions || {};
this.watchOptions.ignored = this.watchOptions.ignored || /node_modules/;

chokidar always reads the ignored option as undefined even if i try to edit the value of this.watchOptions just right before setting it's options.

this.watchOptions.ignored = this.watchOptions.ignored || /node_modules/;

const options = {
      ignoreInitial: true,
      persistent: true,
      followSymlinks: false,
      atomic: false,
      alwaysStat: true,
      ignorePermissionErrors: true,
      ignored: this.watchOptions.ignored,
      usePolling,
      interval,
    };

it works only with me the way I did the change
So what's wrong about it? and if I can write a test for this how would I test it.

lib/Server.js Outdated
}
// ignoring node_modules folder by default
options.watchOptions.ignored =
options.watchOptions.ignored || /node_modules/;

I think we need use here [/node_modules/]. also need add tests to avoid future regressions

plz check Node6

I think this error is unrelated to this PR...

CI is green
