Usage

ReactScript has a simgle export that is a custom react hook useScript.

The useScript hook will return the status of the tag that you can listen for to handle different states in your rendering, but you can also pass in named callbacks onLoad and onFailure.

open ReactScript

let onLoad = (event: Webapi.Dom.Event.t) => {
  Js.log2("Loaded", event)
}

let onFailure = (event: Webapi.Dom.Event.t) => {
  Js.log2("Failed", event)
}

/* only a single script tag is created per unique url */

let scriptStatus: Script.status = Script.useScript(~src=url, ~onLoad, ~onFailure)

switch scriptStatus {
| Idle => <div> {"Idle"->React.string} </div>
| Loading => <div> {"Loading"->React.string} </div>
| Ready => <div> {"Ready"->React.string} </div>
| Failed => <div> {"Failed"->React.string} </div>
}

No Callback Props:

let scriptStatus: Script.status = Script.useScript(~src=url, ())
