# rescript-use-subscription

## ⚠️ Deprecated

The `use-subscription` package is now just a wrapper for `use-sync-external-store`. New bindings can be found [here](https://github.com/illusionalsagacity/rescript-use-sync-external-store) with migration instructions.

This is a zero-cost ReScript binding package for use with [use-subscription](https://github.com/facebook/react/tree/main/packages/use-subscription)

## Usage

Usage is essentially the same as the javascript package:

```reasonml

let {useSubscription} = module(UseSubscription)

@react.component

let make = () => {

  let options = React.useMemo(() => {

    UseSubscription.getCurrentValue: () => Some(1),

    subscribe: callback => {

      callback(. Some(1))

      (.) => ()

    },

  })

  let val = useSubscription(options)

  
{val->Belt.Option.mapWithDefault(React.null, React.int)}

}

```


Uncurried functions are used to eliminate overhead from the ReScript generated output.
