library2.3.0jsnpmunverified

Babel plugins used by the Fable compiler, an F# to JavaScript/TypeScript/Python/Dart/Rust/Beam transpiler. The package is part of the Fable ecosystem. As of v5.0.0, Fable supports multiple compilation targets. The fable-babel-plugins package is typically not installed directly but pulled in as a dependency of the Fable compiler. Its release cadence follows Fable's. Key differentiators: these plugins handle F# specific transformations in the Babel pipeline. Note: The package has been largely superseded by Fable's integrated plugin system.
