flow typesystem support

[cocodrino]

Hi, sorry if it's a noob question but I've added some flow code and I get an error when I run it

Aconr error: unexpected token (9:6) var a: number[] = [2,3,4];

generally flow works out the box with react, because the babel react preset supports flow by default, I changed the babel preset from latest to react but seems doesnt work neither

thank you so much, I'm really enjoying fuse-box over webpack!!!...

Hi! If you changed your babel presets or configuration in general, make sure you remove .fusebox before restarting your process.

hi @nchanged I remove the .fusebox folder but the it still shows the error, this is the full error log

I'm not sure, I just change the preset to react but the logs seems to show than I'm not doing in right way

//my .babelrc file is
{
    "sourceMaps": true,
    "presets": ["react"],
    "plugins": [
        ["transform-react-jsx"]
    ]
}

is it correct???...thank you

It feels like babel can't capture your code. Please run with --debug options, and copy paste the output.

Make sure you .babelrc is in your appRoot (next to node_modules)

If nothing helps, please provide a repository where we can reproduce your error.

hi...thanks for the support @nchanged , I could resolve the problem, I change my babel config adding es2015 (I was replacing es2015 for react because I though than the react-preset include the same es2015 functionalities plus react, now I include both)

 "presets": ["es2015","react"],

thank you
