Replace `ansis` dependency with `util.styleText`

https://nodejs.org/api/util.html#utilstyletextformat-text-options

Available since Node v20.12.0 which matches the current minimum version of v20.19.0.

It seems the only complication is the generateColor function which currently returns an Ansis color specifier, but this type can be replaced with the type of the first parameter of styleText.

PR welcome if anyone wants to work on that!

Can I try this? Please assign me this issue

You may want give node-style-text a try to get a better API. Feel free to inline the code, it's one line of code.

@fisker have you thought about contributing that to Node.js?

Hey @whyang9701, are you still planning to work on this? I'm interested in tackling it if you're not available.

@fisker have you thought about contributing that to Node.js?

No, I'm fine with having this package for myself.

styleText does not currently support RGB or hex colors, making it difficult to remove ansis. I prefer to close this for now, but I'm open to future improvements.

I recommend limit yourself to 16 colors. Many people use terminal themes that only support 16 colors, and by using more than those 16 colors, those themes likely will not work optimally.

I don't think most people are using terminals with only 16 colors; rather, 256-color support is the norm. The vast majority of Linux and macOS terminals support 256 colors by default. I would guess that, in most cases, colors should display correctly—perhaps with some fallback if necessary.

[silverwind]

It's not about color support in the terminal, but having consistent readable output across all terminal color themes.

Some people have light terminals, some have dark ones. If you output for example a static RGB yellow, it will likely look bad on of the two color schemes. By limiting yourself to the basic 16 colors which are covered by all terminal themes, you can ensure the color stays readable.

[sxzz]

I think it depends on the use case. In tsdown, RGB colors are only used for package names. We can assign a consistent color to each package name. However, if we limit ourselves to just 16 colors, there may be duplicates.
