In case of a text file its contents will be interpreted as template string (options.text). If the input file is a JSON file it can contain any of the available options.

Options

Options will be merged in following order:

1. Loader Options
2. Resource Query
3. Input file (in case of a JSON input file)

    /* ... */
  }
}
