`transform` support

[troy351]

Hey, thanks for making this plugin, would it support transform (i.e. modify file contents) like rollup-plugin-copy and CopyWebpackPlugin ?

+1, this is a requirement for me as well as I transform xml to json during build and would like to have this in dev mode as well.

edit: looking at the source for rollup-plugin-copy it seems simple enough to do. I need to finish a project first and might give it a shot afterwards.

This feature will be really very welcome.

Hey @sapphi-red , transform should support folders and every file inside the folder (maybe skip binary files) should be copied with this transform. At least that's how CopyWebpackPlugin works

I ended up using rollup-plugin-copy, works just fine

transform is supported, should we close this issue? @sapphi-red

Folders are not supported right now

You can use a glob to grab all the folders files, that will work.

[troy351]

any examples？

[FezVrasta]

{
  src: 'folder/*',
  dest: 'build/folder',
  transform: content => content + 'b',
}

[troy351]

└─folder1
    │  abc.txt
    │  test.png
    │  index.js
    │
    └─folder2
            code.js

I want to copy folder1 and transform all js code, glob not work.

Error: "transform" option only supports a file
