Light set-up for ecmascript6 dev
mkdir proj
cd proj
npm init
npm install babel-cli babel-preset-es2015 --save-dev
mkdir src
touch src/index.js
Your package.json file should contain the following main and script declarations:
{
"main": "src/index.js",
"scripts": {
"build": "babel src/ --presets babel-preset-es2015 --out-dir dist",
"start": "npm run build && node dist/index.js"
},
}
This makes your npm run build use babel to transpile the code in the src dir into the dist dir.
npm start calls build, then runs the transpiled code in dist/index.js.
