Will add a comment to the start of the transpiled code. Since transpiling via Babel is becoming one of the last steps of the build process it's handy to add some tooling around this final step. For instance could be used:
$ npm install babel-plugin-add-header-comment
The following is an example
.babelrc file. Using the following settings the comment will be created using 3 different features:
"This string will be inserted in")
"presets": "es2015""plugins":"add-header-comment""header":"This string will be inserted in a comment header""!node executeThisOutputAddedToHeader.js""?readInTheContentsOfThisFile.txt"
Sometimes you may want to just add headers to specific files. In this case you can do the following:
"presets": "es2015""plugins":"add-header-comment""files":"src/index.js":"header":"This string will be inserted in a comment header"
newLineChar- This is the newline char that should be used by the plugin. Default value:
cache- This is a string which represents what type of operations should be cached. For instance if you wanted to cache both read and command executions you could pass in

commentStart- This is a string which describes how the comment is started/opened. For instance if you'd like you're comment to start with

COMMENT END*/pass in
