A plugin to transform decorators on function parameters using BabelJS: http://babeljs.io/

Babel Plugin Transform Function Parameter Decorators

This is a plugin for Babel 6 that is used to transform function parameter decorators into calls to the decorator function within the body of the decorated function:

foo('foo');

function foo(@bar baz) {
    console.log(baz); // 'bar';
}

function bar(@baz qux) {
    console.log(qux); // 'foo';

    return 'bar';
}

NOTE:

This package depends on babel-plugin-transform-decorators-legacy

Installation & Usage

npm install babel-plugin-transform-decorators-legacy babel-plugin-transform-function-parameter-decorators

Add the following line to your .babelrc file:

    {
        "plugins": [
            "transform-decorators-legacy",
            "transform-function-parameter-decorators"
        ]
    }

NOTE: Order of Plugins Matters!

If you are including your plugins manually and using transform-decorators-legacy, make sure that transform-decorators-legacy comes before transform-function-parameter-decorators.

NOTE: This will not work with arrow functions!

Nor will any other decorators for that matter. If you need to use function parameter decorators please consider not using an arrow function.
