How do you set debounce time for Rollup's file watcher?

[jakobrosenberg]

Documentation Is:

• Missing
• Needed
• Confusing
• Not Sure?

Please Explain in Detail...

I often see double builds from rollup when updating multiple files. It would be helpful if the documentation provided information on how to increase the debounce time.

Your Proposal for Changes

Add debounce info to the documentation.

#3502 Will give you the configuration you want

Thanks @lukastaegert.

I've tried out the v2.9.0, but it seems I have to set delayBuild to 2000+ ms for it to have any effect. The two file changes I'm trying to debounce are ~15-20 ms apart.

[lukastaegert]

Interesting. That should have been debounced even by the initial delay of 200ms. Would be interesting if you could set up some kind of repro, e.g. a simple Rollup build and an additional script that modifies two files similar to what is happening for you. Note that there is one file which is not debounced at the moment which is the rollup config file.
