babel-set-presets

Install

npm install babel-set-presets -g

Usage

Run the command

babel-set-presets

Why

When you install presets as dev dependencies like this.

"devDependencies": {
  "babel-cli": "^6.6.5",
  "babel-core": "^6.7.2",
  "babel-preset-es2015": "^6.6.0"
}

You need to also either add a .babelrc file or add this property to the package.json file.

"babel": {
  "presets": [
    "es2015"
  ]
}

babel-set-presets will crawl your deps and find your presets and update package.json.
