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

SSR hook - Server-Site Rendering hook for React

Make Server-Site Rendering as easy as possible without any framework. Move your website to SSR almost without changes in your code.

Usage

Only one line difference

Client

import { useSSRHook } from "ssr-hook";

const [items, error, isLoading, reload] = useSSRHook<Item[]>("/api/items");

SEO

import { useHeaders } from "ssr-hook";

useHeaders({
    title: "About me | My website",
    description: "This page is about me.",
    image: window.location.origin + "/logo.png",
    canonical: window.location.origin + window.location.pathname,
});

Server

import { render } from "ssr-hook/server";

const { headers, body } = render(origin, url, <App />);

Installation

npm install ssr-hook

Create new project with SSR hook

npx ssr-hook --init my-new-project

Move your project to SSR

Client

All data that you need to have rendered have as GET method and change all your data fetch that you need to have rendered to useSSRHook:

const [items, error, isLoading, reload] = useSSRHook<Item[]>("/api/items");

Change render dom to hydrate:

createRoot(rootElement).render(<App />); => hydrateRoot(rootElement, <App />);

If your development server is on different origin you can use:

import { setSSROrigin } from "ssr-hook";
if (process.env.NODE_ENV === "development") setSSROrigin("http://localhost:1200");

Server

You can just use function render that return headers and body as string and handle it as you wish.

import { render } from "ssr-hook/server";

const { headers, root, renderingData } = render(origin, url, <App />);

const html = `<!doctype html>
<html lang="en">

<head>
  <meta charset="utf-8" />
  ${headers}
</head>

<body>
  <div id="root">${root}</div>
  ${renderingData}
  <script src="/bundle.js"></script>
</body>

</html>`;

Here is example with using express:

import { renderToHTML } from "ssr-hook/server";
import express, { Request, Response } from "express";
import { readFile } from "fs/promises";

const origin = "http://localhost:3000";

const app = express();

// just example of an endpoint
app.get("/api/items", async (req, res) => {
    return [{ title: "Item1" }, { title: "Item2" }];
});

app.get("*", async (req, res) => {
    const indexHtml = await readFile("../index.html", "utf-8");
    const html = await renderToHTML(origin, req.url, indexHtml, <App />);
    res.set("Content-Type", "text/html");
    res.send(html);
});

app.listen(PORT, () => console.log(`SSR is listening on ${LOCALHOST}`));

renderToHTML

There is necessary to have <div id="root"></div> in body and main bundle js script load at the end of the index.html!
