ESLint checking of files containing FlowType annotations

Package Exports

  • eslint-plugin-flowtype

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (eslint-plugin-flowtype) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

eslint-plugin-flowtype

A plugin for ESLint that strips FlowType type annonations before linting the files.

If your code uses flow type annotations ( http://flowtype.org/ ) and you would like to lint it using ESLint currently the only option is using babel-eslint as ESLint parser instead of the default Espree.

However, Babel-Eslint currently monkey patches ESLint and I had lots of issues with upgrading to newer versions of ESlint and Babel-Eslint.

This plugins strips the type annotations before handing off the file for linting as such you are able to use the latest and greates ESLint parser: Espree on FlowType'd code.

Internally the plugin makes use of Recast for performing AST transforms and stripping the annotations together with esprima-fb parser( which is now deprecated but i couldn't get flow-parser to play nice with recast as such had to use esprima ).

The plugin also preserves the line numbers by using Recast source maps.
