Can you provide a screenshot of what it's supposed to look like?

My errors in Node.js aren't colored so this may be expected behavior.

error.js

throw new Error('error message');

Ok, this is my errors in Node.js

for this example i would expect it to have the same color as when i run node --loader @esbuild-kit/loader main.ts

I investigated this, and I'm not sure if there's a solution.

We pipe the stderr here so that experimental warnings can be removed.

It can be changed to inherit to support colors (TTY), but we lose suppressing warnings.

Alternatively, we can look for another way to suppress warnings (eg. in-process), but I haven't found a way.

I wrote a filter function for stderr to solve this problem.

But because the automatic feature of v8 is too confidential I cannot overcome it so the error message Error: <message error> will become Error：<message error>. I use 「：」in Japanese to ignore this automatic feature

Can I make such a drag request?

I'm not sure what you mean, but a pull request will help me understand what you're doing.

Thanks!
