AssetNamingStrategy

The AssetNamingStrategy determines how file names are generated based on the uploaded source file name, as well as how to handle naming conflicts.

Signature

interface AssetNamingStrategy {
  generateSourceFileName(originalFileName: string, conflictFileName?: string): string;
  generatePreviewFileName(sourceFileName: string, conflictFileName?: string): string;
}

Members

generateSourceFileName

Given the original file name of the uploaded file, generate a file name to be stored on the server. Operations like normalization and time-stamping can be performed in this method.

The output will be checked for a naming conflict with an existing file. If a conflict exists, this method will be invoked again with the second argument passed in and a new, unique file name should then be generated. This process will repeat until a unique file name has been returned.

generatePreviewFileName

Given the source file name generated in the {@link generateSourceFileName} method, this method should generate the file name of the preview image.

The same mechanism of checking for conflicts is used as described above.
