And it works for FlowType also:
JSTwister is a Javascript productivity booster. It's goal is to offer all sorts of common refactors(eg adding automatically imports statements in code etc ) and unit testing assistance. Currently it is in early alpha, meaning is under heavy development and the feature set is slim.
The plan is to gradually add super useful features to it, depending on the demand and feedback coming from you.
Follow it's development at https://www.jstwister.com/docs/getting-started/ or follow us on twitter (@jstweetster).
You need to have Node >= 6.0 installed and available in PATH.
You can also watch us a https://www.jstwister.com or follow us on Twitter(@jstweetster) for updates and interesting articles on Javascript code quality!
Please note that JSTwister is a commercial product and some of it's features will require a license in the future , while MANY of them will remain FOREVER free.
For now feel free to use all of it's feature as you please, whether for PERSONAL or COMMERCIAL purposes!
