[Feature]: Allow output.filename to be a function #2526
Description
What problem does this feature solve?
I want to have dynamic output path for different entry points.
In webpack I used it this way:
output: {
filename: ({ runtime }) => {
switch (runtime) {
case ENTRY_SW:
return `${ENTRY_SW}.js`;
case ENTRY_CHARTING_LIBRARY_CUSTOM_CSS:
return `assets/lib/empty.js`;
default:
return `[name].[${hashType}].js`;
}
},
},I see that rspack can now accept a function for output: web-infra-dev/rspack#3483 .
If I understand correctly how does it work, it seems that now this can be implemented in rsbuild?
What does the proposed API look like?
type FilenameConfigValue = string | (pathData: JsPathData, assetInfo?: JsAssetInfo) => string;
type FilenameConfig = {
js?: FilenameConfigValue;
css?: FilenameConfigValue;
svg?: FilenameConfigValue;
font?: FilenameConfigValue;
image?: FilenameConfigValue;
media?: FilenameConfigValue;
}; output: {
filename: {
js: ({ runtime }) => {
switch (runtime) {
case ENTRY_SW:
return `${ENTRY_SW}.js`;
case ENTRY_CHARTING_LIBRARY_CUSTOM_CSS:
return `assets/lib/empty.js`;
default:
return `[name].[${hashType}].js`;
}
},
},
},
