Steps to writing Javascript in 2018:
1. mkdir and touch necessary files.
2. install and configure babel.
35. Start configuring webpack.
900. open app.js

I love gulp.

Or have a good framework that install a nice boilerplate or directly a nice boilerplate?

Then is :
Donwload boilerplate /Install boilerplate
Download dependencies
Run
Profit

Not using create-react-app or a better boilerplate is suicide

Used a few of them, then removing/replacing the unnecessary dependencies was a pain ...

@donnico That's cool. I could work on a CLI that generates all dependencies needed for a type of project. could be MERN or MEAN.

@romangraef Haven't tried that. Is it easier than Webpack?

@willol Not when you work for a company that requires you to do everything from scratch.
If you use starters, you're on fire.

3. Profit

Ohh that WATERFALL!

3mb+ of files for boilerplate is fucking ridiculous.

Clone create-react-app.
npm install or yarn install as if it makes a difference.
Look at node_modules.
Internalise the fact that this is your app, without any of the dependencies that *you* will actually need.
