babel-preset-env SyntaxError: Unexpected token with spread properties

Question

Why its not accepting spread properties ? I am using babel-preset-env for this.

.babelrc

Answer 1

The Object rest spread operator will probably be a future feature of an ECMAScript specification (it's in stage 3 for the moment).

For now, it can be supported thanks to Babel but you have to use the transform-object-rest-spread plugin.

{
    "presets": [
        "react",
        [
            "env",
            {
                "targets": {},
                "debug": true,
                "modules": "commonjs"
            }
        ],
        "transform-object-rest-spread"
    ]
}
