Doesn't work with babel require hook

[aaronshaf]

I have the following in foo.js:

require('babel-core/register')({
  'plugins': ['typecheck']
})

require('./bar')

In bar.js:

export default function () {}

Error:

@aaronshaf which version of babel are you using?

[aaronshaf]

6.0.15

[phpnode]

Can't replicate this with babel 6.1.x but I notice that you didn't include the commonjs modules transformer (or the es2015 preset) in your config so it should have failed for different reasons. Leads me to suspect you have a .babelrc file which might be overriding something, if so please post the contents here. Will reopen if you can provide a more detailed repro.

I am having this same issue. I have app.js:

require('babel-core/register')();
require('./bar.js');

And in bar.js:

let a: string = 'test';

With .babelrc:

{
    "plugins": [
        "typecheck"
    ],
    "presets": [
        "es2015"
    ]
}

When I run node app, I get the following error:

C:\Users\Scott\Documents\GitHub\test\node_modules\babel-core\lib\transformation\file\index.js:540
      throw err;
      ^

If I remove the : string portion, it runs fine. If I also just do babel app.js bar.js --out-dir dist, I get the output:

app.js -> dist\app.js
SyntaxError: bar.js: Unexpected token (1:8)

global babel-cli@6.2.0 (babel-core@6.2.1) babel-core@6.2.1 typecheck@3.0.2

I feel like I am missing something obvious here, but I cannot get even a basic example to run with the plugin.

@sgodwin424 please try adding babel-plugin-syntax-flow to your list of plugins or babel-preset-react to your list of presets then try again.

[sgodwin424]

Thank you. Adding babel-preset-react or babel-plugin-syntax-flow and babel-transform-flow-strip-types seems to work. I was under the impression that this plugin was standalone as the installation does not seem to suggest otherwise, but I suppose it makes sense that it would need other flow plugins.

Maybe this should be added to the installation section to avoid these issues? I have been wanting to use flowtype, but they do not support Windows yet, so when I found this plugin, I was quite thrilled to be able to use it in part. This is also the reason why I did not have the other flow plugins.

@sgodwin424 there's a weird issue with plugin ordering in babel6 which makes it impossible to specify that this plugin depends on those others automatically. I've added a note to the README in #56
