babel-preset-proposals

A Babel 7 preset that manages experimental proposal plugin dependencies, ordering, and default options. Current version 0.4.0 (released 2021-02-24), requires Node >=10. Key differentiators: automatically handles plugin ordering and option defaults for decorators and pipeline operator, removes plugins handled by @babel/preset-env, and supports all major TC39 proposals via boolean or object configuration. Release cadence is irregular; last release was over 3 years ago. Notable changes include removal of jsonStrings/nullishCoalescingOperator/optionalChaining options in v0.2.0 and addition of classStaticBlock in v0.4.0. This preset helps avoid common misconfigurations of Babel proposal plugins.
