## babel-bridge
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
```js
|
||
|
|
peerDependencies: {
|
||
|
|
"babel-core": "6.x"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
cannot change to
|
||
|
|
|
||
|
|
```js
|
||
|
|
peerDependencies: {
|
||
|
|
"@babel/core": "6.x"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
without it being a breaking change.
|
||
|
|
|
||
|
|
### Solution
|
||
|
|
|
||
|
|
To address this, we're releasing this bridge package, to allow users to do
|
||
|
|
|
||
|
|
|
||
|
|
```js
|
||
|
|
peerDependencies: {
|
||
|
|
"babel-core": "6.x | ^7.0.0-bridge"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
then where users of this package would originally have done
|
||
|
|
|
||
|
|
```sh
|
||
|
|
npm i some-package babel-core
|
||
|
|
```
|
||
|
|
|
||
|
|
to install Babel 6, they could now do
|
||
|
|
|
||
|
|
|
||
|
|
```sh
|
||
|
|
npm i some-package babel-core@^7.0.0-bridge @babel/core
|
||
|
|
```
|
||
|
|
|
||
|
|
to install the bridge package, and install Babel 7's core.
