Rollup Flow plugin

Build Status

This Rollup plugin will remove Flow type annotations during bundling using flow-remove-types.

Install

npm install --save rollup-plugin-flow

var rollup = require('rollup').rollup;
var flow = require('rollup-plugin-flow');

rollup({
  entry: 'main.js',
  plugins: [ flow() ]
}).then(...);

Options

Provide options as an object argument to flow().

all - Transform all files, not just those containing @flow comments.

Default: false

var flow = require('../');

module.exports = {
  plugins: [ flow({ all: true }) ],
  format: 'cjs'
};

pretty - Remove flow types without replacing them with whitespace.

Default: false

Note: Typically source maps are not necessary for this transform, however source maps are recommended when generating "pretty" results.

var flow = require('../');

module.exports = {
  plugins: [ flow({ pretty: true }) ],
  format: 'cjs'
};
