babel-plugin-transform-flow-comments

Turn flow type annotations into comments.

You should be able to use this plugin instead of babel-plugin-flow-strip-types to preserve the / @flow / directive and still use flow.

Example

In

``javascript
function foo(bar?) {}
function foo2(bar?: string) {}
function foo(x: number): string {}
type B = {
name: string;
};
export type GraphQLFormattedError = number;
import type A, { B, C } from './types';
import typeof D, { E, F } from './types';
`

Out

`javascript
"use strict";

function foo(bar /:: ?/) {}
function foo2(bar /:: ?: string/) {}
function foo(x /: number/) /: string/ {}
/*:: type B = {
name: string;
};*/
/:: export type GraphQLFormattedError = number;/
/:: import type A, { B, C } from './types';/
/:: import typeof D, { E, F } from './types';/
