    This plugin installs the Base64 flow-node to be used within Axway API Builder's flow editor. The flow-node provides two methods:


    Encodes data into a string using the base64 encoding scheme. If the data is a Buffer or a string, its bytes will be encoded as-is. Otherwise, the data will be first converted using JSON.stringify, and then encoded.

    Param Type Required Description
    data number|boolean|string|object y The data to encode.


    Decodes a base64 encoded string into the provided format (see "Decode data as" parameter).

    Param Type Required Description
    data string y The base64 encoded string.
    as boolean|buffer|number|object|string n If "buffer", data will be returned as a Buffer. If "string", data will be converted to utf-8 String. If "number", the data will be converted to a utf-8 string and then parsed as base 10 integer. If "boolean”, the data will be converted to a utf-8 string and if "false", "0", or empty string, the value is false (otherwise, true). If "object", the value is converted to a utf-8 string and parsed using JSON.parse. Default: buffer
