About this fork

Enables the flow type-checking of directories. Flow's binary is optimized for taking directories as input. Leveraging this can dramatically improve performance over the original repository, for larger codebases.
Uses textual output rather than JSON output, so error output is not truncated.
Removes outdated options that flow no longer supports.
Removed the abort option, effectively making it the default behavior.

gulp-flowtype

Run Facebook's Flow in your gulp pipeline

Installation

$ npm install --save-dev gulp-flowtype

Running Windows?

Flow hasn't provided an official binary as of yet, you can follow the issue here #6.

If you do manage to compile flow and get it running. You can set the path to your own executable using an environment variable.

$ set FLOW_BIN=/path/to/flow

Usage

var react = require('gulp-react');
var flow = require('gulp-flowtype');

gulp.task('typecheck', function() {
  return gulp.src('./*.js')
    .pipe(flow({
        all: false,
        weak: false,
        declarations: './declarations',
        killFlow: false,
        beep: true,
        abort: false
    }))
    .pipe(react({ stripTypes: true })) // Strip Flow type annotations before compiling
    .pipe(gulp.dest('./out'));
});
