These are some very minimal changes to the standard express.js generated app.js file. It looks nice, “=>” syntax is getting easier to read the more I use and get used to it. Note: I took out a lot of unrelated code to isolate the topic of the blog. This example is for getting a development, learning environment ready to use Babel.js with Express on the back and front ends.
How’d I do it?
Using Babel’s “babel-node” cli tool, its compiling in real time in the development env. For production, do not use babel-node, you’ll want to compile with Babel.js then run with node. Just use “npm install -g babel-cli” and babel-node is already there and built in.
I also included eslint for good measure. Make sure to “npm install –save-dev babel-eslint” and set the parser to “babel-eslint.”
What else do you suggest that can I do to the app.js to take advantage ES6 features, without straying too far from the default?
