Type definitions for setContext

[flekschas]

I am wondering if it's possible to annotate setContext calls such that the exposed variables are typed.

For example:

<!-- MyLogger.svelte -->
<script context="module">
  import { setContext } from 'svelte';
  /**
   * Log something
   * @type {(message: string) => void}
   */
  function log(message) {
    console.log(message);
  }

  setContext('my-logger', log);
</script>

My problem is that even though log has type annotations, when someone gets the function via getContext('my-logger') the type is unknown.

I wonder if there's a way to add type annotations to setContext.
