Support packages

Use these alongside Fable.Core 5.2.0, with Xantham package versions matching your generator release.

Utility types

Xantham.Fable.Core

dotnet add package Xantham.Fable.Core

The support library represents TypeScript constructs such as property keys, indexed access, and nominal brands. Its utility types erase at runtime.

open Fable.Core.JS

type Config = { Timeout: int }

let timeoutKey = typekeyof<Config, int> _.Timeout
let timeout = TypeKeyOf.item timeoutKey { Timeout = 30 }

Open Fable.Core.JS for the erased types. Helper functions are available from the auto-opened XanthamFableCore module.

See the API reference for the full surface.

Standard libraries

Xantham.Fable.Core.TS

dotnet add package Xantham.Fable.Core.TS

Generated bindings for TypeScript's esnext and DOM libraries. Add this package to the consumer project alongside Xantham.Fable.Core.

open Fable.Core.TS

type PendingRequest = {
    Completion: Promise<string>
    Target: Fable.Core.TS.Dom.EventTarget
}

The Es module is auto-opened from Fable.Core.TS. DOM types stay under Fable.Core.TS.Dom.

Custom dependency mappings can use a separately generated standard library instead. Adding an assembly reference does not change the generator's configured group dispositions.

See the standard-library reference.

Node bindings

Xantham.Fable.Node

Bindings for @types/node are under development. The package is currently marked as a stub in the repository; treat it as work in progress for this release.

For a specific Node package, generate from its installed declarations and review the resulting findings and compile errors.

TypeScript.Wire is separate

Xantham.TypeScript.Wire is a .NET compiler client for tools that inspect TypeScript. A Fable app using generated bindings does not need it.
