`tsdx` uses `.browserslistrc` to determine how to transpile the source code. By default it supports very old environments. By specifying relatively modern targets, the bundle size has been reduced with ~40%. This also significantly increases performance and readability of the output, because babel’s regenerator runtime isn’t used anymore. The output target can’t be set to something too new, because `tsdx` uses an older version of terser which isn’t compatible with all new syntax (e.g. optional chaining).

I dig it, thank you! |

Do you have any ETA of when this will be released? I understand the language server and VSCode extension don’t need a release of the language service, because they are linked in this mono repo and bundled when released, but I’d like to use these language service changes in monaco-tailwindcss. (Also I’d love to collaborate with the Tailwind team to work on this and integrate it in the playground.) 😄 |

I see you did! Thank you! |
