For displaying directory structures, check out tree:

$ tree bundle-app
bundle-app/
├── dist
│   └── index.html
├── package.json
├── package.lock.json
├── src
│   ├── hero.js
│   └── index.js
└── webpack.config.js

2 directories, 6 files
Enter fullscreen mode Exit fullscreen mode

If you're on a mac, brew install tree

Hopefully this is the last packaging tool and we all start using this one. Who remembers bower? :D

I was just checking your process and one of your initial command doesn't seems to be working
npx webpack ./index.js -o ./

it's throwing unknown command error

npx webpack --entry ./index.js -o ./ should work

Makes sure you install webpack first.. It could be as a result of webpack not being installed on your machine. Otherwise use the confirmation file.

I've installed the webpack, my issue seems to be different. Webpack-cli is not detecting webpack as a command. Can you help me with this?

okay, try installing webpack and the webpack-cli globally, that should do the trick

this way our browser only ever loads a single JavaScript file that it needs to run and this significantly decreases load time

How does loading a single javascript file decreases load time? I assume a single javascript file would increase load time as the file will be bigger?

I'm confused...

I was just about to dive into webpack. This helped. Thanks for sharing!
