@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
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
"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';*/
