I had a lot of questions when it came to packaging up my JavaScript library, such as:
- minify?
- output to single file or maintain file/folder structure?
- have an esm build (or cjs)?
- transpile or not? (e.g. jsx -> createElement)
- package.exports setup?
- other package.json settings? (e.g. type)
- multiple outputs - dev/prod?
- what is "double bundling"?
With the hope of answering these questions, and more, I created the Modern Guide to Packaging Your JavaScript Library.
I created it on GitHub so that, as time goes on, it will (hopefully) remain fresh and updated - if I had written it as an article, then no one else could have contributed as easily, and it may have gone stale.
Hopefully this guide is helpful to you, too.
