How to run Node.js app with ES6 features enabled?
To run Node.js app with ES6 features enabled, we install a few packages.
We enable ES6 features by running
npm install --save-dev babel
npm install --save-dev babel-cli
npm install --save-dev babel-preset-es2015
npm install --save-dev babel-preset-stage-0
npm install --save-dev nodemon
to install Babel and nodemon.
Then we create a .babelrc file in the project root and add
{
"presets": ["es2015", "stage-0"]
}
to let us run our project with ES6 features.
Then in package.json, we write
{
//...
"scripts": {
"watch": "babel -w src/ -d dist/",
"build": "babel src/ -d dist/",
"serve": "babel -w src/ -d dist/ | nodemon --watch dist",
"test": "echo \"Error: no test specified\" && exit 1"
}
//...
}
to run babel with nodemon to let us run our Node.js app with Babel.
