Fidelity.CloudEdge.Runtime

F# and Fable bindings for the full Cloudflare Workers Runtime API surface

Worker-side bindings — Use this package to write Cloudflare Workers in F#. For managing Cloudflare resources from .NET applications, see Fidelity.CloudEdge.Management.

What is this?

Fidelity.CloudEdge.Runtime provides F# type bindings for the APIs available inside a running Cloudflare Worker. These bindings are designed for use with Fable to compile F# to JavaScript that runs on Cloudflare's edge network.

The package includes 727 types generated from the official @cloudflare/workers-types TypeScript definitions using Glutinum, plus hand-crafted helper modules for idiomatic F# usage.

Quick Example

open Fidelity.CloudEdge.Worker.Context
open Fidelity.CloudEdge.KV

let handler (request: Request) (env: obj) (ctx: ExecutionContext) =
    promise {
        // Access KV namespace from environment bindings
        let kv = env?MY_KV_NAMESPACE :?> KVNamespace

        // Read a value
        let! value = kv.get "my-key"

        // Return a response
        return Response.create($"Value: {value}")
    }

How It Works

This package includes both compiled .NET DLLs (for IDE support and type checking) and F# source files in a fable/ folder. When Fable compiles your project, it reads the source files directly and produces JavaScript that calls the Cloudflare Workers runtime APIs.

Package Structure

lib/net10.0/           Compiled DLLs for IDE intellisense
fable/                 F# sources for Fable compilation
  Core/                  Shared utilities
  Runtime/
    CloudEdge.AI/        Workers AI bindings
    CloudEdge.D1/        D1 database bindings
    CloudEdge.DurableObjects/  Durable Objects bindings
    CloudEdge.Hyperdrive/      Hyperdrive bindings
    CloudEdge.KV/        KV storage bindings
    CloudEdge.Queues/    Queue bindings
    CloudEdge.R2/        R2 object storage bindings
    CloudEdge.Vectorize/ Vector database bindings
    CloudEdge.Worker.Context/  Core types + full workers-types surface (727 types)

Requirements

  • Fable 4.x for F# to JavaScript compilation
  • A Cloudflare Workers project (typically set up with Wrangler)
  • Fable.Core and Fable.Promise (included as transitive dependencies)
  • Fidelity.CloudEdge.Management — 32 F# clients for Cloudflare's REST Management APIs (create databases, deploy workers, manage buckets, configure tunnels, etc.)
