sourcemapFileNames

• Type: string | ((chunkInfo) => string)
• Optional

Defined in: packages/rolldown/src/options/output-options.ts:205

The pattern to use for sourcemaps created from entry points, or a function that is called per entry chunk with PreRenderedChunk to return such a pattern.

Patterns support the following placeholders:

• [format]: The rendering format defined in the output options. The value is any of InternalModuleFormat.
• [hash]: A hash based only on the content of the final generated sourcemap. You can also set a specific hash length via e.g. [hash:10]. By default, it will create a base-64 hash. If you need a reduced character set, see output.hashCharacters.
• [chunkhash]: The same hash as the one used for the corresponding generated chunk (if any).
• [name]: The name of the corresponding chunk.

Forward slashes (/) can be used to place files in sub-directories. This pattern will also be used for every file when setting the output.preserveModules option.
