This is a Webpack loader for Flowcheck.
Flowcheck is a runtime assertions library that uses Flow syntax but is meant to be ran in development.
Chain this loader with jsx?stripTypes so types are stripped in JS code:
// Webpack configmoduleexports =...module:loaders:test: /\.jsx?$/ loaders: 'jsx?harmony&stripTypes' 'flowcheck' exclude: /node_modules/;
You can use this with or without using Flow or TypeScript itself.
It can also be a nice first step towards migrating code to Flow.
