Can't import flow types with sourceType script

[Hilzu]

I'm writing an app with CommonJS modules and Flowtype. When setting sourceType to script it becomes impossible to use the Flow import type syntax. As far as I can tell Flow only has ES2015 style syntax for type imports.

Here's my eslint configuration:

{
  "parser": "babel-eslint",
  "parserOptions": {
    "sourceType": "script"
  },
  "plugins": [
    "flowtype",
  ],
  "extends": [
    "eslint:recommended",
    "plugin:flowtype/recommended"
  ]
}

Code like this triggers parse errors:

const { promisify } = require("./promise")
import type { Context } from "koa" 

Example error:

  15:1  error  Parsing error: 'import' and 'export' may appear only with 'sourceType: module'

  13 | const { promisify } = require("./promise")
  14 |
> 15 | import type { Context } from "koa"
     | ^

Is there a way to use CommonJS modules and the import type syntax together with babel-eslint ?

Thank you for the issue. Now that @babel/eslint-parser has been released, we are making this repository read-only. If this is a change you would still like to advocate for, please reopen this in the babel/babel monorepo.
