What is the best way to work in "watch" mode? Kotlin incremental js compilation works fast, but webpack is extremely slow on kotlin std lib (1,5 Mb, ~5s to rebuild in watch mode). Kotlin DCE speeds up webpack build, but slows down incremental js compilation...

[snrostov]

without stdlib - 1768ms for webpack. looks good

Does webpack reparse files that remain unchanged?

[snrostov]

looks like he is checked only by modtime. rsync -c solves this

[snrostov]

trying noParse option now...

[konsoletyper]

What about rsync. Do you copy files somewhere before passing them to webpack (as I suggested before)?

[konsoletyper]

Did you try to do it using Gradle sync task?

[konsoletyper]

So I guess you copy everything and mtime gets updated, which signals webpack to reparse everything

What about rsync. Do you copy files somewhere before passing them to webpack (as I suggested before)?

yes, I'm running rsync -c from gradle

[snrostov]

hmm... thanks!

[konsoletyper]

Or https://docs.gradle.org/current/dsl/org.gradle.api.tasks.Copy.html

[konsoletyper]

Ah, sync task will remove everything

[snrostov]

noParse: [/kotlin/] webpack option speed ups to 1002ms, even if kotlin.js is updated

[snrostov]

after removing source map, webpack build takes 81ms
