Fable core lib and bindings for native JS objects, browser and Node APIs
npm install --save fable-core
For general information on how to use Fable, please check the documentation.
fable-core uses ES5 syntax but it calls some ES2015 APIs (
so you will need a polyfill like core-js to use it
in environments that don't support these APIs.
The default distribution uses ES2015 modules in order to produce smaller sizes with bundlers
like Rollup (embedded with
fable-compiler) or Webpack 2.
If you are not bundling your app, you'll probably need the UMD distribution instead (see below).
F# project (.fsproj)
F# script (.fsx)
#r "node_modules/fable-core/Fable.Core.dll"open Fable.Coreopen Fable.Import
Usage without bundling
If you're writing a Node application and don't use a module bundler, you just need
fable-compiler to use
fable-core UMD distribution by passing
among the compiler options.
If you target the browser and prefer to load JS dependencies asynchronously instead of bundling,
you can easily load
fable-core files with require.js as follows:
