jsonResponse(options)

Options

Optional table is passed directly to Luvit's json.stringify function and dkjson which it uses internally:

• indent - when indent (a boolean) is set, the created string will contain newlines and indentations. Otherwise it will be one long line.

• keyorder - keyorder is an array to specify the ordering of keys in the encoded output. If an object has keys which are not in this array they are written after the sorted keys.

• level - this is the initial level of indentation used when indent is set. For each level two spaces are added. When absent it is set to 0.

• buffer - buffer is an array to store the strings for the result so they can be concatenated at once. When it isn't given, the encode function will create it temporary and will return the concatenated result.

• bufferlen - when bufferlen is set, it has to be the index of the last element of buffer.

• tables tables is a set to detect reference cycles. It is created temporary when absent. Every table that is currently processed is used as key, the value is true.

• exception - when exception is given, it will be called whenever the encoder cannot encode a given value.
