Search and replace static import statements Codeshift transformer
This jscodeshift codemod/transform replaces import source text.
It was created specifically to deal with private repositories- their @name is not a valid module name.
However this tool also can be useful for generating creating mounting of libraries.
A fork of cjs-to-es6 has this codemod builtin. Pass a --renameImportSource=^@(.*)/_$1/ arument to the run to run your own rename, or let it default to that search & replace.
