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 🙏

vite-plugin-vue-server-ref

NPM version

Share state between clients and Vite server.

Install

npm i -D vite-plugin-vue-server-ref

Add plugin to your vite.config.ts:

// vite.config.ts
import ServerRef from 'vite-plugin-vue-server-ref'

export default {
  plugins: [
    ServerRef({
      state: {
        /* Your custom initial state */
        foo: 'bar',
        object: {
          count: 0
        }
      }
    })
  ]
}

Use import it in your modules (server-ref:[key])

import foo from 'server-ref:foo'

console.log(foo.value) // bar

foo.value = 'foobar'

// same as other modules / clients imported the server ref with same key
// or even refresh the pages
console.log(foo.value) // foobar

Or working with reactive object (server-reactive:[key])

import object from 'server-reactive:object'

console.log(object.count) // 0

Type Support

As server import can't infer the type correctly (by default it's ServerRef<any>), you can using as to specify the type.

import type { ServerReactive, ServerRef } from 'vite-plugin-vue-server-ref/client'
import _foo from 'server-ref:foo'
import _object from 'server-ref:object'

const foo = _foo as ServerRef<string>
const object = _object as ServerReactive<{ count: number }>

foo.value // string
object.count // number

Controls

import foo from 'server-ref:foo'

foo.$syncUp = false // make it download only

foo.value = 'foobar' // won't send to server or other clients
import foo from 'server-ref:foo'

foo.$syncDown = false // make it upload only

// changes from other clients won't be received
import foo from 'server-ref:foo'

// listen to server change
foo.$onSet((value) => {
  console.log(`Changes from server: ${value}`)
})

Diffing

When working with reactive objects, you can add ?diff to make the syncing incremental (deep diff).

import object from 'server-ref:object?diff'

console.log(object) // { foo: ..., bar: ... }

object.foo.nested = 'bar'
// the patch will be sent as '{ foo: { nested: 'bar' }}}'
// instead of the entire object
