How to use ES6+ in nodejs
This article is about how to use es6+
in nodejs project
Initialising project with npm
npm init -y
Installing babel plugins for es6+ features
npm i -D @babel/cli @babel/core @babel/plugin-proposal-class-properties @babel/plugin-transform-runtime @babel/preset-env
Adding babel support for project
touch .babelrc
Paste the following content in .babelrc
{
"presets": ["@babel/preset-env"],
"plugins": ["@babel/plugin-proposal-class-properties", "@babel/transform-runtime"]
}
Babel is not a compiler or interpreter it is just a transpiler so we have to transpile es6
to es5
using babel then we have to execute that transpiled code. For that we can write npm script.
Add the following script to package.json
"build": "babel src -d dist",
"start": "npm run build && node dist"
Now create src
folder and start writing es6+
code inside that folder. Run npm start
it will create dist
folder inside that folder we can find transpiled code.
Cheers!!!
