是否有脚本或工具可以帮助将流自动迁移到TypeScript？

我有一个使用流的旧react本机模块。有几千行代码。现在，我想使用TypeScript将这些代码迁移到一个新项目中。我正在寻找一个自动工具，以帮助我解决繁琐的类型转换工作。如果它能解决大约90%的问题，我将不胜感激。 比如说,

• 将所有

  .js

  文件更改为'

  ts

  或

  tsx

  文件，如：

• 转换类型

有什么建议吗

最后，我用

还有其他选择：

Usage: flow-to-ts [options]

Options:
  -V, --version                    output the version number
  --inline-utility-types           inline utility types when possible, defaults to 'false'
  --prettier                       use prettier for formatting
  --semi                           add semi-colons, defaults to 'false' (depends on --prettier)
  --single-quote                   use single quotes instead of double quotes, defaults to 'false' (depends on --prettier)
  --tab-width [width]              size of tabs (depends on --prettier) (default: 4)
  --trailing-comma [all|es5|none]  where to put trailing commas (depends on --prettier) (default: "all")
  --bracket-spacing                put spaces between braces and contents, defaults to 'false' (depends on --prettier)
  --arrow-parens [avoid|always]    arrow function param list parens (depends on --prettier) (default: "avoid")
  --print-width [width]            line width (depends on --prettier) (default: 80)
  --write                          write output to disk instead of STDOUT
  --delete-source                  delete the source file
  -h, --help                       output usage information

你试过了吗？嗨，我用过了。有一个错误<代码>错误：EISDIR:目录上的非法操作，在cli.js:79:23的Object.readSync（fs.js:498:3）处读取。我应该使用文件globs，而不是目录路径。

// Flow
import type { Type1, Type2 } from ./dir/to/path
// Typescript
import { Type1, Type2 } from ./dir/to/path

// Flow
type Date = {
  toString: () => string,
  setTime: (time: number) => number
}

// TypeScript
interface Date {
  toString(): string;
  setTime(time: number): number;
}

// Flow 
value: ?string 
// TypeScript 
value: string | null

yarn global add @khanacademy/flow-to-ts
flow-to-ts --write --delete-source ${myProjectPath}/src/**/**.js
