swc-jit

library0.2.0jsnpmunverified

swc-jit v0.2.0 provides a just-in-time transpiler for Node.js using the experimental loader API, allowing TypeScript files to be executed directly without precompilation. It integrates with SWC for fast transpilation and supports source maps for debugging. The package is designed as a lighter alternative to ts-node, leveraging SWC's speed. However, it relies on Node's experimental loaders, which may change across Node versions. The package has no recent updates and may be considered in maintenance mode.
