Configuration

alias

Type: Record<string,string>
Default: null

Alias configuration, where each key is an alias and the value is a relative path based on the working directory.
When Rollup resolves a file, if the path starts with an alias, the plugin will replace it with an absolute path (path.join(cwd, alias, the rest of source)). If the path omits the file name, the plugin will attempt to find an index.xx file in the directory in the order specified by extensions. It will then calculate the relative path based on the file that imported this path and perform the replacement.

cwd

Type: string
Default : process.cwd()

Working directory path.

extensions

Type: string[]
Default: ['.js', '.ts'] | ['.ts', '.js']

When the file name is omitted (determined by path.extname), it will look for an index.xx file in the directory in this order, and throw an exception if not found.
The plugin will check if there is a tsconfig.json in the working directory. If so, the default value is ['.ts', '.js'], otherwise it is ['.js', '.ts'].
