This repo holds what we're calling a "bridge" package that is meant to ease the transition for libraries that use "babel-core" as a peer dependency for Babel 6.
The issue with Babel 7's transition to scopes is that if a package depends on
Babel 6, they may want to add support for Babel 7 alongside. Because Babel 7
will be released as
@babel/core instead of
babel-core, maintainers have
no way to do that transition without making a breaking change. e.g.
cannot change to
without it being a breaking change.
To address this, we're releasing this bridge package, to allow users to do
peerDependencies:"babel-core": "6.x | ^7.0.0-bridge"
then where users of this package would originally have done
npm i some-package babel-core
to install Babel 6, they could now do
npm i some-package babel-core@^7.0.0-bridge @babel/core
to install the bridge package, and install Babel 7's core.
