prettier
An opinionated code formatter that enforces consistent style across every language your project speaks.

@babel/core
The core JavaScript compiler that transforms next-generation syntax into code every browser and runtime can understand.

Immutable document, selection, and transaction data structures for the CodeMirror code editor
