I need to perform these conversions
without intermediate buffers.

1) string -> gzip -> base64
2) base64 -> gunzip -> string

How to do that with io.pipe?

    thank you

    it is first gzip a string then base64 the gzip-ed content
    how you would do that?

    Thank you for the great example.

    In practice the base64 encoded string
    ---
    sRequest64 := buf.Bytes()
    ---
    will be sent to web service which should accept a string.

    The receiving part should accept a string and then write it buffer.

    How to modify?
    --
    // Read with no intermediate buffer
    r, err := gzip.NewReader(base64.NewDecoder(base64.StdEncoding, &buf))

    I modified it, now it works accepting strings:
