Pipelines#

Pipeline is a computation expression used to combine HttpHandlers in a declarative manner.

The result of the computation expression is a standard Giraffe HttpHandler (docs), which means that it's easily composable with other parts of the Giraffe ecosystem.

Example:

open Saturn

let headerPipe = pipeline {
    set_header "myCustomHeader" "abcd"
    set_header "myCustomHeader2" "zxcv"
}

let endpointPipe = pipeline {
    plug fetchSession
    plug head
    plug requestId
}

You can also use any HttpHandler defined in Giraffe in pipelines (using plug) - documentation can be found here.
