Starting with React 15, React will warn that unitless values will no longer bw appended with px and the appending will be removed in future versions of react,this is a codemod that finds unitless specifications in your code and appends with px.
npm install jscodeshift -gnpm install react-style-px-suffix-codemod- run this script with
jscodeshift -t node_modules/react-style-px-suffix-codemod <DIRECTORY_OR_FILE_TO_RUN_ON>
It is also possible to pass a --ignore flag when running to specify properties that you do not want to have px appended, example below. The properties should be comma delimited
jscodeshift -t <THIS_SCRIPT> <DIRECTORY_OR_FILE_TO_RUN_ON> --ignore=fontSize,hats
