disallow duplicate use: directives

📖 Rule Details

We can define any number of use: directive with the same action, but duplicate directives with the exact same action and expression are probably a mistake. This rule reports reports use: directives with exactly the same action and expression.

<script>
  /* eslint svelte/no-dupe-use-directives: "error" */
</script>

<!-- ✓ GOOD -->
<div use:clickOutside use:clickOutside={param} />
<div use:clickOutside={foo} use:clickOutside={bar} />

<!-- ✗ BAD -->
<div use:clickOutside use:clickOutside />
<div use:clickOutside={param} use:clickOutside={param} />

🔧 Options

Nothing.
