 ### `class Encoder`
 
-#### `constructor(form[, boundary]) -> {Encoder}`

   - **{FormDataLike}** form - A FormData object to encode. This object must be a spec-compatible FormData implementation.
   - **{string}** boundary - An optional boundary string that will be used by the encoder. If there's no boundary string is present, Encoder will generate it automatically.
 
 Creates a multipart/form-data encoder.
