[Question] Is parcel suitable for building a npm package?

Choose one: is this a 🐛 bug report or 🙋 feature request?

A question.

🎛 Configuration (.babelrc, package.json, cli command)

I’m writing a npm package, where I use the npm script to bundle the src files together into a single file. But I found the dist file doesn’t bundle everything together, which causes this error:

/Users/changyan/Documents/repos/test/node_modules/react-animation-wrapper/lib/index.js:12:29: Cannot resolve dependency './emptyFunction'...

and when looking into the bundled file I noticed it’s requiring something like this:

var e,r=require("./emptyFunction")

My npm script looks like this:

{
  "build": "parcel build ./src/index.js --out-dir ./lib",
}

And I searched around on the internet but didn’t find something useful to resolve my problem. Also, I read a post that addressed that rollup or webpack are probably better choices for writing npm packages. Is that true? Or am I using it wrong?

@djstein it looks parcel build --target node was added in #652.

For libraries Microbundle is intended for building multiple outputs from the same input. In theory you get CJS, ESM, UMD, .min.js, .d.ts, etc. in one pass.

I don’t think that’s in scope for Parcel?
