Dear Guilers,
I'd like to implement a web server using the (web server) module, but
allow for “streaming” results. The way I imagine this would look like,
is something like this:
(define (request-handler request body)
(values '((content-type . (text/plain)))
;; This function can build its response by writing to
;; ‘port’, rather than to return the whole body as a
;; string.
(lambda (port)
(format port "Hello world!"))))
(run-server request-handler)
Is this possible with the (web server) module? If so, how?
What you describe is exactly how it works. The second value can be a bytevector, #f or a procedure that takes a port as argument. Here is an example use [0] and here is the code [1][0] https://framagit.org/a-guile-mind/culturia.next/blob/master/culturia/web/helpers.scm#L34 [1] https://git.savannah.gnu.org/cgit/guile.git/tree/module/web/server.scm#n198
