# Flourish font watcher

The function exported from this module will call
`window.template.update()` (or another function) when any new
fonts are loaded.

## How to install

`npm install -s @flourish/font-watcher`

Then import it with:

```js
import addFontWatcher from "@flourish/font-watcher";
```

## Usage

If no callback is specified, then `addFontWatcher` will call
`window.template.update()` whenever it detects that a new font
has been loaded:

```js
addFontWatcher();
```

If you supply a callback, then it will be called with a
[FontFaceSetLoadEvent](https://developer.mozilla.org/en-US/docs/Web/API/FontFaceSetLoadEvent)
object as the parameter. For example, you can do:

```js
addFontWatcher(function () {
    console.log("Fonts have loaded");
});
```


Calls update() when new fonts are loaded.
