Answer 1

I have had success using the following setup. I am using the plugin with the babel loader in my webpack module rather than in .babelrc
In webpack:
query: {
presets: [
"es2015", "react", "stage-0", {
"plugins": [
"./schema-build/babelRelayPlugin"
]
}
]
}
In .babelrc:
{
"passPerPreset": true,
"presets": [
"react",
"es2015",
"stage-0"
]
}
