Nuxtjs Guideline: DataFetching — Use $fetch for non-reactive requests. Description: $fetch for event handlers and non-component code. Do: $fetch in event handlers or server routes. Don't: useFetch in click handlers. Good Example: async function submit() { await $fetch('/api/submit', { method: 'POST' }) }. Bad Example: async function submit() { await useFetch('/api/submit') }. Severity: High. Docs: https://nuxt.com/docs/api/utils/dollarfetch.
