fetch

A minimal composable DSL for fetching JSON from HTTP (GET/POST).

NOTE: this IS NOT a general purpose HTTP client. If you need one, there are plenty to choose from. If you still want to use this and lack some features, use hack to access underlying HttpRequestMessage before sending.

It comes with builders allowing for sync (blocking) and async calls (both Task and Async variants):

  • fetch<'T> - Sync
  • fetchTask<'T> - Task async
  • fetchAsync<'T> - F# async
  • rq<'T> - just the request - use it to create parts that can be used in the fetch* builders

Examples

#r "paket: nuget Arquidev.Fetch ~> 1"
open Arquidev.Fetch

// POST with JSON body
let result = fetch<{|success: bool|}> {
    POST "https://api.example.com/users"
    Body {| name = "John"; email = "john@example.com" |}
    Authorization "Bearer token123"
}
if result.success then ...

// hack it
let data = fetch<Data> {
    GET "https://api.example.com/data"
    hack (fun req -> req.Headers.Add("X-Custom", "value"))
}

Look at tests.fsx for more.

Composition

Note: the order of composition is important if the same element is specified in both rq and fetch - the last declaration wins

// compose it

let common = rq {
    Authorization "Bearer token"
    UserAgent "MyApp/1.0"
}

fetch<Data> {
    GET "http://localhost"
    common
}

Console logging

*NOTE: for full headers and request/response content set env var: FETCH_DEBUG=1 or in code Fetch.debugEnabled true|false *

Fetch.enableLogs ()
//call(s) here
