Detailed description
cssSourceTrace
Optional | Type:
CssSourceTraceUserOptions| Default:false
Mark the token source file in the output CSS for tool rules.
Remark
Off by default. When turned on, the tokens: token <= source-file comment will be inserted before the generated CSS rules.
Used to check which source code file a certain tool class comes from. You can pass in { root } to control the relative path base in the annotation.
This capability is intended for debugging and demo acceptance, and production builds are usually kept turned off to reduce product volume.
default value
false
babelParserOptions
Optional | Type:
(Partial<Options> & { cache?: boolean | undefined; cacheKey?: string | undefined; cacheMaxEntries?: number | undefined; cacheMaxSourceLength?: number | undefined; })| Version: ^3.2.0
Configuration options for @babel/parser.
experimentalJsFastPath
Optional | Type:
boolean | "oxc"
Experimental JS transpilation fast path.
Remark
Currently OXC is only attempted when source maps are turned off on the call side and there are no module graphs, module replacements, ignore call/tag template semantics.
The current release line requires Node ^22.18.0 || >=24.11.0. OXC will still automatically fall back to Babel when loading fails.

Optional | Type:
Partial<Omit<Result, "file">>| Version: ^3.2.0
Configuration options for postcss.
tailwindcssRuntimeOptions
Optional | Type:
TailwindCssRuntimeOptions
Customize Tailwind CSS runtime parameters.
logLevel
Optional | Type:
"info" | "warn" | "error" | "silent"
Controls the command line log output level.
Remark
The default is info, which can be set to silent to block all output.
