cwd: 'babelrc' doesn't find .babelrc.js
I was having trouble getting babel to export aliased modules -- they were always transpiling with absolute paths instead of relative ones. I had been configuring babel with a .babelrc.js file instead of .babelrc --- when I renamed it, things started working as expected.
It would be ideal if .babelrc.js files were supported!
I'm happy to put together a PR for this. It looks like find-babel-config isn't very active, it might make sense to handle this from within this module.
find-babel-config supports .babelrc.js though: https://github.com/tleunen/find-babel-config/tree/master/test/data/babelrcjs
Yeah... But we'll have to rework that option with Babel 7 anyway I believe...
babel.config.js works differently than the other filenames (see https://babeljs.io/docs/en/next/babelconfigjs).
So I wonder how useful is the babelrc custom cwd that we have instead of always using the root project... Defaulting on the root project, except if you provide a custom cwd. No more custom magic values.
@fatfisz That's odd - I was getting absolute paths (as if it weren't finding the cwd) when I had a .babelrc.js, and it started working with a .babelrc.
@tleunen In the case of a monorepo, with Babel 7's babel.config.js will also be used to help babel identify where package-specific configuration is. I'm not sure of the extent of what the cwd option does --- but the babel.config.js file may not always be the 'correct' working directory.
What do you mean exactly. If you have one babel.config.js in each "package" in the monorepo. It will be ok. (But then I agree that the project root won't be the same).
But anyway, I think using the new core function loadPartialConfig (as explained here https://github.com/babel/babel/pull/7472) will solve all issues related to that. Since we'll be relying on babel to know what file is used, thus knowing the "root".
It looks like babel.config.js will be used for setting up global config, and will ignore .babelrc files:

Unless you opt into them using the babelrcs or babelrcRoots options
