A jscodeshift codemod designed to split combined var declarations into multiple declarations

split-var-declarations.js

module.exports = function transformer(file, api) {
  const j = api.jscodeshift;

  return j(file.source)
    .find(j.VariableDeclaration)
  	.filter(d => d.value.declarations.length > 1)
  	.forEach(path => {
    	console.log(path)
    	const newDeclarations = path.value.declarations.map(dec =>
          j.variableDeclaration(path.value.kind, [
            dec
          ]))
        console.log(newDeclarations)
    	j(path).replaceWith(newDeclarations)
    })
  	.toSource()
