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 🙏

Readme

@Proact/core

Proact is an template engine for node js which renders React like jsx functional components to static HTML or XML.

Features

  • Optimized for fast server rendering
  • Supports async rendered views
  • Output caching
  • Built-in express view engine

install

npm install @proact/core

Basic usage

Rendering HTML

// templates/Paragraph.jsx
import Proact from '@proact/core'

export default (props, context) => (
  <p>{context.body}</p>
)
// index.js
const Proact = require('@proact/core')

const renderer = Proact.createRenderer({ views: 'templates' })

renderer
  .renderToString('Paragraph.jsx', { body: 'lorem ipsum' })
  .then(function (html) {
    console.log(html)
  })

Rendering XML

// templates/data.jsx
import Proact from '@proact/core'

export default async (props, context) => {
  return (
    <data
      xmlns="http://www.myorg.org/schemas/data/0.9"
      m:xmlns="http://www.myorg.org/schemas/meta/0.9"
    >
      <title>{context.title}</title>
      <m:category>{context.category}</m:category>
    </data>
  )
}
// index.js
const Proact = require('@proact/core')

// set docType to xml
const renderer = Proact.createRenderer({
  views: 'templates',
  docType: 'xml',
})

renderer
  .renderToString('data.jsx', {
    title: 'lorem ipsum',
    category: 'dolor',
  })
  .then(function (xml) {
    console.log(xml)
  })

Built-in express view engine

// server.js
const express = require('express')
const Proact = require('@proact/core')

const PORT = 3100
const app = express()

Proact.initializeViewEngine(app, { views: 'views' })

app.get('/', (req, res) => {
  const context = { title: 'Basic Example' }
  res.render('index', context)
})

app.listen(PORT, function () {
  console.log(`server running at http://localhost:${PORT}`)
})

JSX Views

Proact supports only functional components. The component gets two parameters: props and context.

import Proact from '@proact/core'

export default (props, context) => (
  <div>{context.user.email}</div>
)

Components can also be async.

import Proact from '@proact/core'

export default async function (props, context) {
  const data = await getSomeDataAsync()
  return (
    <ul>
      {data.map(item => <li>{item}</li>)}
    </ul>
  )
}

Insert HTML content

import Proact, { UnsafeHtml } from '@proact/core'

export default (props) => {
  const { name } = props
  return (
    <UnsafeHtml html={`<h1>Hello ${name}</h1>`} />
  )
}

Use content cache

import Proact, { Cache } from '@proact/core'

const getItems = function (numberOfItems) {
  return new Promise((resolve) => {
    setTimeout(() => {
      resolve(
        Array(numberOfItems)
          .fill()
          .map(() => 'Lorem ipsum dolor sit amet')
      )
    }, 500)
  })
}

const List = async (props) => {
  const items = await getItems(props.numberOfItems)
  return (
    <ul>
      {items.map((item) => (
        <li>{item}</li>
      ))}
    </ul>
  )
}

const CachedList = () => {
  return (
    <Cache
      key={`large-list`}
      // maxAge duration in seconds
      maxAge={60}
      content={() => <List numberOfItems={1000} />}
    />
  )
}

Short example

import Proact, { Cache, UnsafeHtml } from '@proact/core'
import MarkdownIt from 'markdown-it'
import db from '../db'

const markdown = new MarkdownIt()

const Post = async (props) => {
  const { slug } = props
  const post = await db.getPostBySlug(slug)
  const content = markdown.render(post.content)
  return (
    <section>
      <h1>{post.title}<h1>
      <h1>{post.abstract}<h1>
      <UnsafeHtml html={content} preserveWhitespaces />
    </section>
  )
}

const RelatedPosts = async (props) => {
  const { slug } = props
  const posts = await db.getRelatedPosts(slug)
  return posts.map(item => (
    <article>
      <h3>{item.title}</h3>
      <p>{item.abstract}</p>
      <a href={`/blog/${slog}`}>read more...</a>
    </article>
  )
}

const BlogPost (props, context) {
  const { slug } = context
  return (
    <>
      <Cache
        key={`post_${slug}`}\
        maxAge={360}
        content={() => (
          <Post slug={slug} />
        )}
      />
      <Cache
        key={`relatedposts_${slug}`}
        maxAge={60}
        content={() => (
          <RelatedPosts slug={slug} />
        )}
      />
    </>
  )
}
