@wclr Could you take a look at this PR? It should be fairly minor. |

Keen to try this out! We've got a large code base that takes ~30s to startup right now and would love to cut that down. |

Any progress on this? |

ts-node can pull all of these options from your tsconfig.json, is there some reason that can't be done when using ts-node-dev? https://typestrong.org/ts-node/docs/configuration#via-tsconfigjson-recommended |
|
Any updates here? This would also reduce our build times by quite a bit |

If you want an alternative solution, I've switched ts-node-dev to https://github.com/esbuild-kit/tsx, it's great! :) ts-node-dev was always causing problems (high CPU, compatibility macOS/Linux) and I wanted a tool that combined watching and transpiling (so that I didn't have to install something like nodemon) Example: (I'm unaffiliated with tsx) |

@wclr Could you take a look at this PR? Basically, we cannot use this tool with ts-node + swc, since it overrides the transpileOnly property. |

from what I can see in the official docs, ts-node does not use -W short flag for swc, there's only a full --swc option

Was the original options['transpile-only'] assignment not working properly? Is there an edge case that had to be resolved with a ternary operator?
