Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Nuxt module for mitt library - enable fully typed events and autocompletion

👏 Credits to developit author of the mitt library


Features

  • ✅  Nuxt 3 support
  • 🤞  Easy to use composable
  • 🔌  auto-import - mitt provided by plugin
  • ♻️  Optimized with Vue/Nuxt Lifecycle hooks

📦 Install

Install nuxt-mitter as dependency:

    npm install nuxt-mitter

Add it to the modules section of your nuxt.config.{ts|js}:

    modules: ['nuxt-mitter']

⚠️ Optional - but strongly recommended

Provide your event.d.ts file with type MitterEvents:

export type MitterEvents = {
  foo: string
  bar?: string
}

[!IMPORTANT] ❗  Name of type must be MitterEvents

🚧  Improvements coming soon...


Add mitt key to your nuxt.config.{ts|js} and provide path to types

    mitt: {
        types: '...'   //your path './types/eventTypes.d.ts'
    }

🏁 That's it! You can now use My Module in your Nuxt app

🚀 Examples

Fire an event with the composable useMitter

<!--SayHello.vue-->
<script setup lang="ts">
  const { emit } = useMitter()
  const onClick = () => {
    emit('hello', 'Hello 🫠🖖')
  }
</script>

<template>
  <button @click="onClick">
    Say Hello
  </button>
</template>

Listen to an event with the composable useMitter

<!--SomeWhereInTheComponentTree.vue-->
<script setup>
const { listen } = useMitter()

listen('hello', e => alert(e))
</script>

Types

export type EmitFunction = <K extends keyof MitterEvents>(event: K, payload?: MitterEvents[K]) => void

export type EventHandlerFunction = <K extends keyof MitterEvents>(
  event: K,
  handler: (payload: MitterEvents[K]) => void
) => void

export type ListenFunction = <K extends keyof MitterEvents>(
  event: K,
  handler: (payload: MitterEvents[K]) => void
) => void

export interface UseMitterReturn {
  /**
   * Emits an event with an optional payload.
   * @param event The event name to emit.

   */
  on: EventHandlerFunction

  /**

   */
  listen: ListenFunction
