eslint-plugin-flowtype-errors

Demo

Why?

• Lower barrier: Any editor that has ESLint support now supports Flow 🎉
• Less editor configuration: No need to change your entire workflow to incorporate flow. No multiple-linters-per-file nonsense.
• Simple: It's literally just an ESLint rule! Just install the dependency, add a flowconfig, and you're good to go!

Getting Started

This guide assumes that you have installed eslint, babel, babel-plugin-transform-flow-strip-types and configured flow. Check out the from-scratch guide for the full guide on getting started.
