Feature Request : Package.json Babel RC support (instead of .babelrc)

[SilentCicero]

Parcel is awesome.

I would love if I could just use the package.json to specify my .babelrc settings. Currently, that doesn't seem to be supported, and I'm forced to include an additional .babelrc file. I hate those little files. Any chance this could be an option like in webpack?

Thoughts on this?

On 1.5.1 configuring babel through package.json works for me. Do you have an example config which fails?

[optimisticupdate]

Ok, on 1.5.1 it works, but on current master this was removed with #559.

Why was this removed? How can I use babel-stage-2 or stage-0 or any other babel preset with 1.6?

[SilentCicero]

A babel rc file ATM. Yeah, I would really like this added back, package Json is an acceptable place for babel settings almost everywhere else in the ecosystem. Parcel should accommodate.

@SilentCicero how did you get this to work with a babelrc file? I tried the babelrc file approach and it still blew up when trying to use features that required stage-2. I went back to 1.5 and everything works.

Isn't stage 0/1 further ahead than stage 2? Maybe a deer ate issue.

@SilentCicero yes. My project is just using stage-2 though and I'm unable to use any stage-2 features. From what I understand of the 1.6 release notes, babel-preset-env is automatic but how do I add to that?

Babel config in package.json should already work. See:

parcel/src/transforms/babel.js

Lines 193 to 199 in 595252c

	async function findBabelRc(asset) {
	if (asset.package && asset.package.babel) {
	return asset.package.babel;
	}
	return await asset.getConfig(['.babelrc', '.babelrc.js']);
	}
